The IBM Watson iOS SDK using the Alchemy News service on Bluemix returns a string result which requires parsing to pull out the fields like url and cleaned title. ref: https://github.com/watson-developer-cloud/swift-sdk
I pull the string into an array and parse it in swift3 using some string methods but this is pretty ordinary and can produce unpredictable results
Is there a more elegant approach where I can access specific fields, like the url and cleaned title which I am passing to a UITableViewCell to select and segue to the url link.
sample code:
let alchemyDataNews = AlchemyDataNews(apiKey: apiKey)
let failure = { (error: Error) in print(error) }
let start = "now-14d" // 7 day ago
let end = "now" // today
let query = ["count": "15",
"dedup": "true",
"q.enriched.url.title": "[IBM]",
"return": "enriched.url.url,enriched.url.title" "enriched.url.title,enriched.url.entities.entity.text,enriched.url.entities.entity.type"]
Also I have noticed the search string [IBM] has a prefix of 0, i.e. 0[IBM] and have also seen an "A". What do these prefixes mean and where are they documented
Here is one way you can access the fields from a returned payload.
alchemyDataNews.getNews(from: "now-4d", to: "now", query: queryDict, failure: failWithError) { news in
for doc in (news.result?.docs)! {
var cleanedTitle = doc.source?.enriched?.url?.cleanedTitle
var author = doc.source?.enriched?.url?.author
var title = doc.source?.enriched?.url?.title
}}
Also, here is a nice API reference link for alchemy data which contains all of the request parameters and filters.

Safely turning a JSON string into an object
(28 answers)
Closed 7 years ago.
I want to parse a JSON string in JavaScript. The response is something like
var response = '{"result":true,"count":1}';
How can I get the values result and count from this?
The standard way to parse JSON in JavaScript is JSON.parse()
The JSON API was introduced with ES5 (2011) and has since been implemented in >99% of browsers by market share, and Node.js. Its usage is simple:
const json = '{ "fruit": "pineapple", "fingers": 10 }';
const obj = JSON.parse(json);
console.log(obj.fruit, obj.fingers);
The only time you won't be able to use JSON.parse() is if you are programming for an ancient browser, such as IE 7 (2006), IE 6 (2001), Firefox 3 (2008), Safari 3.x (2009), etc. Alternatively, you may be in an esoteric JavaScript environment that doesn't include the standard APIs. In these cases, use json2.js, the reference implementation of JSON written by Douglas Crockford, the inventor of JSON. That library will provide an implementation of JSON.parse().
When processing extremely large JSON files, JSON.parse() may choke because of its synchronous nature and design. To resolve this, the JSON website recommends third-party libraries such as Oboe.js and clarinet, which provide streaming JSON parsing.
jQuery once had a $.parseJSON() function, but it was deprecated with jQuery 3.0. In any case, for a long time, it was nothing more than a wrapper around JSON.parse().
WARNING!
This answer stems from an ancient era of JavaScript programming during which there was no builtin way to parse JSON. The advice given here is no longer applicable and probably dangerous. From a modern perspective, parsing JSON by involving jQuery or calling eval() is nonsense. Unless you need to support IE 7 or Firefox 3.0, the correct way to parse JSON is JSON.parse().
First of all, you have to make sure that the JSON code is valid.
After that, I would recommend using a JavaScript library such as jQuery or Prototype if you can because these things are handled well in those libraries.
On the other hand, if you don't want to use a library and you can vouch for the validity of the JSON object, I would simply wrap the string in an anonymous function and use the eval function.
This is not recommended if you are getting the JSON object from another source that isn't absolutely trusted because the eval function allows for renegade code if you will.
Here is an example of using the eval function:
var strJSON = '{"result":true,"count":1}';
var objJSON = eval("(function(){return " + strJSON + ";})()");
alert(objJSON.result);
alert(objJSON.count);
If you control what browser is being used or you are not worried people with an older browser, you can always use the JSON.parse method.
This is really the ideal solution for the future.
If you are getting this from an outside site it might be helpful to use jQuery's getJSON. If it's a list you can iterate through it with $.each
$.getJSON(url, function (json) {
alert(json.result);
$.each(json.list, function (i, fb) {
alert(fb.result);
});
});
If you want to use JSON 3 for older browsers, you can load it conditionally with:
<script>
window.JSON ||
document.write('<script src="//cdnjs.cloudflare.com/ajax/libs/json3/3.2.4/json3.min.js"><\/scr'+'ipt>');
</script>
Now the standard window.JSON object is available to you no matter what browser a client is running.
The following example will make it clear:
let contactJSON = '{"name":"John Doe","age":"11"}';
let contact = JSON.parse(contactJSON);
console.log(contact.name + ", " + contact.age);
// Output: John Doe, 11
If you pass a string variable (a well-formed JSON string) to JSON.parse from MVC #Viewbag that has doublequote, '"', as quotes, you need to process it before JSON.parse (jsonstring)
var jsonstring = '#ViewBag.jsonstring';
jsonstring = jsonstring.replace(/"/g, '"');
You can either use the eval function as in some other answers. (Don't forget the extra braces.) You will know why when you dig deeper), or simply use the jQuery function parseJSON:
var response = '{"result":true , "count":1}';
var parsedJSON = $.parseJSON(response);
OR
You can use this below code.
var response = '{"result":true , "count":1}';
var jsonObject = JSON.parse(response);
And you can access the fields using jsonObject.result and jsonObject.count.
Update:
If your output is undefined then you need to follow THIS answer. Maybe your json string has an array format. You need to access the json object properties like this
var response = '[{"result":true , "count":1}]'; // <~ Array with [] tag
var jsonObject = JSON.parse(response);
console.log(jsonObject[0].result); //Output true
console.log(jsonObject[0].count); //Output 1
The easiest way using parse() method:
var response = '{"a":true,"b":1}';
var JsonObject= JSON.parse(response);
this is an example of how to get values:
var myResponseResult = JsonObject.a;
var myResponseCount = JsonObject.b;
JSON.parse() converts any JSON String passed into the function, to a JSON object.
For better understanding, press F12 to open the Inspect Element of your browser, and go to the console to write the following commands:
var response = '{"result":true,"count":1}'; // Sample JSON object (string form)
JSON.parse(response); // Converts passed string to a JSON object.
Now run the command:
console.log(JSON.parse(response));
You'll get output as Object {result: true, count: 1}.
In order to use that object, you can assign it to the variable, let's say obj:
var obj = JSON.parse(response);
Now by using obj and the dot(.) operator you can access properties of the JSON Object.
Try to run the command
console.log(obj.result);
Without using a library you can use eval - the only time you should use. It's safer to use a library though.
eg...
var response = '{"result":true , "count":1}';
var parsedJSON = eval('('+response+')');
var result=parsedJSON.result;
var count=parsedJSON.count;
alert('result:'+result+' count:'+count);
If you like
var response = '{"result":true,"count":1}';
var JsonObject= JSON.parse(response);
you can access the JSON elements by JsonObject with (.) dot:
JsonObject.result;
JsonObject.count;
I thought JSON.parse(myObject) would work. But depending on the browsers, it might be worth using eval('('+myObject+')'). The only issue I can recommend watching out for is the multi-level list in JSON.
An easy way to do it:
var data = '{"result":true,"count":1}';
var json = eval("[" +data+ "]")[0]; // ;)
If you use Dojo Toolkit:
require(["dojo/json"], function(JSON){
JSON.parse('{"hello":"world"}', true);
});
As mentioned by numerous others, most browsers support JSON.parse and JSON.stringify.
Now, I'd also like to add that if you are using AngularJS (which I highly recommend), then it also provides the functionality that you require:
var myJson = '{"result": true, "count": 1}';
var obj = angular.fromJson(myJson);//equivalent to JSON.parse(myJson)
var backToJson = angular.toJson(obj);//equivalent to JSON.stringify(obj)
I just wanted to add the stuff about AngularJS to provide another option. NOTE that AngularJS doesn't officially support Internet Explorer 8 (and older versions, for that matter), though through experience most of the stuff seems to work pretty well.
If you use jQuery, it is simple:
var response = '{"result":true,"count":1}';
var obj = $.parseJSON(response);
alert(obj.result); //true
alert(obj.count); //1
I'm using a website that requires that their API key AND query data be submitted using Webform.Post method. I'm able to get this to work in Python, C# and I'm even able to construct and execute a cURL command which returns a usable JSON file that Excel can parse. I am also using Postman to validate my parameters and everything looks good using all these methods. However, my goal is to build a query form that I can use within Excel but I can't get past this query syntax in PowerBi Query.
For now I am doing a simple query. That query looks like this:
let
url_1 = "https://api.[SomeWebSite].com/api/v1.0/search/keyword?apiKey=blah-blah-blah",
Body_1 = {
"SearchByKeywordRequest:
{
""keyword"": ""Hex Nuts"",
""records"": 0,
""startingRecord"": 0,
""searchOptions"": Null.Type,
""searchWithYourSignUpLanguage"": Null.Type
}"
},
Source = WebMethod.Post(url_1,Body_1)
in
Source
ScreenSnip showing valid syntax
It generates the following error:
Expression.Error: We cannot convert the value "POST" to type Function.
Details:
Value=POST
Type=[Type]
ScreenSnip of Error as it appears in PowerQuery Advanced Editor
I've spend the better part of the last two days trying to find either some example using this method or documentation. The Microsoft documentation simple states the follow:
WebMethod.Post
04/15/2018
2 minutes to read
About
Specifies the POST method for HTTP.
https://learn.microsoft.com/en-us/powerquery-m/webmethod-post
This is of no help and the only posts I have found so far criticize the poster for not using GET versus POST. I would do this but it is NOT supported by the website I'm using. If someone could just please either point me to a document which explains what I am doing wrong or suggest a solution, I would be grateful.
WebMethod.Post is not a function. It is a constant text value "POST". You can send POST request with either Web.Contents or WebAction.Request function.
A simple example that posts JSON and receives JSON:
let
url = "https://example.com/api/v1.0/some-resource-path",
headers = [#"Content-Type" = "application/json"],
body = Json.FromValue([Foo = 123]),
source = Json.Document(Web.Contents(url, [Headers = headers, Content = body])),
...
Added Nov 14, 19
Request body needs to be a binary type, and included as Content field of the second parameter of Web.Contents function.
You can construct a binary JSON value using Json.FromValue function. Conversely, you can convert a binary JSON value to a corresponding M type using Json.Document function.
Note {} is list type in M language, which is similar to JSON array. [] is record type, which is similar to JSON object.
With that said, your query should be something like this,
let
url_1 = "https://api.[SomeWebSite].com/api/v1.0/search/keyword?apiKey=blah-blah-blah",
Body_1 = Json.FromValue([
SearchByKeywordRequest = [
keyword = "Hex Nuts",
records = 0,
startingRecord = 0,
searchOptions = null,
searchWithYourSignUpLanguage = null
]
]),
headers = [#"Content-Type" = "application/json"],
source = Json.Document(Web.Contents(url_1, [Headers = headers, Content = Body_1])),
...

I have been trying to submit a my own form to WFFM. The form I created is identical to the one created with WFFM, that way all fields map correctly.
I began following the following steps: https://jermdavis.wordpress.com/2015/05/18/programmatic-wffm-submissions/
I had to make minor changes to the code in order to get the SubmitActionManager to work
The members of Sitecore.Form.Core.Submit.SubmitActionManager class
have been moved to the IActionExecutor interface.To obtain the
instance of this interface use the
(IActionExecutor)Factory.CreateObject ("wffm/wffmActionExecutor",
false) call.
Below is the code I have so far:
public void SubmitData(ContactUsFormModel data)
{
var results = new List<ControlResult>();
results.Add(makeControlResult(Models.Constants._cufFirstNameID, "First Name", data.FirstName));
results.Add(makeControlResult(Models.Constants._cufLastNameID, "Last Name", data.LastName));
results.Add(makeControlResult(Models.Constants._cufEmailID, "Email", data.Email));
results.Add(makeControlResult(Models.Constants._cufCompanyID, "Company", data.Company));
results.Add(makeControlResult(Models.Constants._cufSubjectID, "Subject", data.Subject));
results.Add(makeControlResult(Models.Constants._cufMessageID, "Message", data.Message));
var formItem = Sitecore.Context.Database.GetItem(Models.Constants._contactUsFormID);
var simpleForm = new SitecoreSimpleForm(formItem);
var saveActionXml = simpleForm.FormItem.SaveActions;
var actionList = Sitecore.Form.Core.ContentEditor.Data.ListDefinition.Parse(saveActionXml);
var actionDefinitions = new List<ActionDefinition>();
actionDefinitions.AddRange(actionList.Groups.SelectMany(x => x.ListItems).Select(li => new ActionDefinition(li.ItemID, li.Parameters) { UniqueKey = li.Unicid }));
var SubmitActionManager = (IActionExecutor)Factory.CreateObject("wffm/wffmActionExecutor", false);
Sitecore.Form.Core.WffmActionEvent sessionID = new Sitecore.Form.Core.WffmActionEvent();// SessionIDGuid
var result = SubmitActionManager.ExecuteSaving(ID.Parse(Models.Constants._contactUsFormID), results.ToArray(), actionDefinitions.ToArray(), true, ID.Parse( sessionID.SessionIDGuid ));
}
private ControlResult makeControlResult(string fieldID, string fieldName, string fieldValue)
{
return new ControlResult(fieldName, fieldValue, string.Empty)
{
FieldID = fieldID,
FieldName = fieldName,
Value = fieldValue,
Parameters = string.Empty
};
}
I wasnt sure where to get Sitecore.Form.Core.Analytics.AnalyticsTracker.SessionId from to use it inside ExecuteSaving, so I used WffmActionEvent.
Also the guide I followed uses Execute, which is now deprecated, so I had to go with ExecureSaving (my best guess).
This however doesn't seem to be posting the submitted data into the databse. I am unable to see any of my submissions inside WFFM Form Reports or inside mongoDB.
The logs however state that the form is being saved to the database, not sure what the other warnings mean.
24688 17:20:39 WARN [WFFM] Tracker.Current is not initialized
24688 17:20:39 INFO AUDIT (sitecore\admin): [WFFM] Form {978DBF4C-0F56-45A8-A9AC-52EF8D995DDF} is saving to db

As you are using Sitecore 8 the form submission is stored in MongoDB. Sitecore's implementation of MongoDB, xDB mostly relies on tracking users, calling them Contacts.
Most data stored in xDB is linked to a Contact via a ContactId. The error messages you are finding in the log are stating that tracking is currently not enabled, therefore no Contact is present and there is no Interaction between the site and user.
Therefore you need to start Sitecore.Tracker I recommend using the following code
if (!Tracker.IsActive)
Tracker.StartTracking();
if (!Tracker.IsActive || Tracker.Current.Contact == null)
{
// handle no tracker and contact
}
Now that you have tracking working you need to use the correct ID for your sessionID variable.
The blog you are following is based on Sitecore 7, in Sitecore 8 Sitecore.Form.Core.Analytics.AnalyticsTracker.SessionId is removed. I decompiled the Sitecore 7 code and Sitecore.Form.Core.Analytics.AnalyticsTracker.SessionId ultimately uses Tracker.CurrentVisit.VisitId.
However this namespace has changed in Sitecore 8, Visits are now called interactions so instead of your variable SessionID you will want to use
Tracker.Current.Interaction.InteractionId;
That should resolve the issue you are currently having but you may need a bit more development to finish it off.
My question is simple but i can not find exact solution. All articles have gor below a line of code:
collection.findOne({hello:'world_no_safe'});
Above codes does work and returns to me undefined error.But it is existed. Anyway, My exact solution is above. Please help me and teach me how to use regex by searching inside of the json api. ı want to use %mysearch data% as a regex expression. ı want to make text search which is used all sentences in json.
For example : i have a json:
[{"data":"Andreas Kollegger explains what kinds of questions you can answer with a graph database. It's not only the big sites that "},{"data":"X explains what kinds of questions you can answer with a graph database. It's not only the big sites that "}]
if i use this expression: collection.findOne({hello:'%Andreas%'});
it has to return first data. Below a real sample from my project.
var mongo = require('mongodb');
var Server = mongo.Server;
var Db = mongo.Db;
var server = new Server('ds053479.mongolab.com', 53479, {auto_reconnect : true});
var db = new Db('orient', server);
db.open(function(err, client) {
client.authenticate('testname', 'fsfsff', function(err, success) {
var collection = db.collection('Models');
collection.insert({Name:'test1'});
// Fetch the document
collection.findOne({Name:'%world_no_safe%'});
});
According to the MongoDB Manual you can use the $regex operator:
collection.findOne({Name: { $regex: '.*world_no_safe.*' }});
I am using parse sdk for backend management for my game. For user signup/login parse api ask for parameter tokenExpiration. I have no idea how to get it from facebook unity sdk.
https://www.parse.com/docs/unity_guide#fbusers-signup
Task<ParseUser> logInTask = ParseFacebookUtils.LogInAsync(accessToken, userId, tokenExpiration);
Got this problem solved by myself using debug_token. Here is the right code on how to do it.
FB.API("/debug_token?input_token="+FB.AccessToken+"&access_token="+FB.AccessToken,Facebook.HttpMethod.GET, AccessTokenCallback);
function AccessTokenCallback(response:String){
Debug.Log(response);
var access = JSON.Parse(response);
Debug.Log("Token Expiration is: "+access["data"]["expires_at"].Value);
}
If you will print the response it will give you a JSON with all information about the access token and you can take whatever info you need about an access token.
Open FacebookAccessTokenEditor.cs and replace original line 81:
formData["batch"] = "[{\"method\":\"GET\", \"relative_url\":\"me?fields=id\"},{\"method\":\"GET\", \"relative_url\":\"app?fields=id\"}]";
by these two:
string getExpiresAt = ",{\"method\":\"GET\", \"relative_url\":\"debug_token?input_token="+accessToken+"\"}";
formData["batch"] = "[{\"method\":\"GET\", \"relative_url\":\"me?fields=id\"},{\"method\":\"GET\", \"relative_url\":\"app?fields=id\"}"+getExpiresAt+"]";
Then open FacebookEditor.cs and in method MockLoginCallback, just before line 220:
isLoggedIn = true;
insert the following lines:
var tokenData = (Dictionary<string, object>)MiniJSON.Json.Deserialize(responses[2]);
var expiresAt = (long)((Dictionary<string, object>)tokenData["data"])["expires_at"];
accessTokenExpiresAt = FromTimestamp((int)expiresAt);
also, add the missing function FromTimestamp which you can copy from AndroidFacebook.cs or IOSFacebook.cs or jus copy from here:
private DateTime FromTimestamp(int timestamp)
{
return new DateTime(1970, 1, 1, 0, 0, 0, 0).AddSeconds(timestamp);
}
Finally, you can call the parse method like you do on IOS or Android or Web:
Task<ParseUser> logInTask = ParseFacebookUtils.LogInAsync(FB.UserId, FB.AccessToken, FB.AccessTokenExpiresAt);
Note: As I have worked on the code, I am not sure of the original line numbers, but I think they are correct. Also, this does not reflect the best coding practices, but since it is used only in a debug context, they're good enough for me.
