I'm writing tests on Postman queries and I'm wondering if there were wildcards to test for equality on a string?
example :
pm.test("projectSheet should includes ", function () {
var jsonData = pm.response.json();
// jsonData.projectSheet === like "projectFile.pdf"
pm.expect(jsonData.projectSheet).to.eql("[*wildcard here*]projectFile.pdf");
});
Thanks for your answers !
You could use a regular expression: pm.expect(jsonData.projectSheet).to.match(/.*projectFile\.pdf/)

Hello I want to extract JSON from below input string.
I have tried bellow regex in java and it is working fine,
private static final Pattern shortcode_media = Pattern.compile("\"shortcode_media\":(\\{.+\\})");
I want in regex for dart.
Input String
<script type="text/javascript">window.__initialDataLoaded(window._sharedData);</script><script type="text/javascript">window.__additionalDataLoaded('/p/B9fphP5gBeG/',{"graphql":{"shortcode_media":{"__typename":"GraphSidecar","id":"2260708142683789190","shortcode":"B9fphP5gBeG","dimensions":{"height":1326,"width":1080}}}});</script><script type="text/javascript">
<script type="text/javascript">window.__initialDataLoaded(window._newData);</script><script type="text/javascript">window._newData('/p/B9fphP5gBeG/',{"graphql":{"post":{"__typename":"id","id":"2260708142683789190","new_code":"B9fphP5gBeG"}}});</script><script type="text/javascript">
(function(){
function normalizeError(err) {
var errorInfo = err.error || {};
var getConfigProp = function(propName, defaultValueIfNotTruthy) {
var propValue = window._sharedData && window._sharedData[propName];
return propValue ? propValue : defaultValueIfNotTruthy;
};
return {}
}
)
Expected json
{"graphql":{"shortcode_media":{"__typename":"GraphSidecar","id":"2260708142683789190","shortcode":"B9fphP5gBeG","dimensions":{"height":1326,"width":1080}}}}
Note: There are multiple json string in input string, i need json of shortcode_media tag
please use
void main() {
String json = '''
{"graphql":
{"shortcode_media":{"__typename":"GraphSidecar","id":"2260708142683789190","shortcode":"B9fphP5gBeG","dimensions":{"height":1326,"width":1080}}},
"abc":{"def":"test"}
}
''';
RegExp regExp = new RegExp(
"\"shortcode_media\":(\\{.+\\})",
caseSensitive: false,
multiLine: false,
);
print(regExp.stringMatch(json).toString());
}
output
"shortcode_media":{"__typename":"GraphSidecar","id":"2260708142683789190","shortcode":"B9fphP5gBeG","dimensions":{"height":1326,"width":1080}}}
Dartpad
The corresponding Dart RegExp would be:
static final RegExp shortcodeMedia = RegExp(r'"shortcode_media":(\{.+\})");
It does not work, though. JSON is not a regular language, so you can't parse it using regular expressions.
The value of "shortcode_media" in your example JSON ends with several } characters. The RegExp will stop the match at the third of those, even though the second } is the one matching the leading {. If your JSON text contains any further values after the shortcode_media entry, those might be included as well.
Stopping at the first } would also be too short.
If someone reorders the JSON source code to the equivalent
"shortcode_media":{"dimensions":{"height":1326,"width":1080},"__typename":"GraphSidecar","id":"2260708142683789190","shortcode":"B9fphP5gBeG"}
(that is, putting the "dimensions" entry first), then you would only capture until the end of the dimensions block.
I would recommend either using a proper JSON parser, or at least improving the RegExp to be able to handle a single nested JSON object - since you seem to already know that it will happen.
Such a RegExp could be:
RegExp(r'"shortcode_media":(\{(?:[^{}]*(?:\{.*?\})?)*?\})')
This RegExp will capture the correct number of braces for the example code, but still won't work if there are more nested JSON objects. Only a real parser can handle the general case correctly.
can anyone help me, I am almost new in Postman.
my issue is as follow:
I send a POST request and get a message asresponse:
{
"errorCode": 1000,
"errorDescription": "Account is not verified by Admin!"
}
this message is already saved in a var named "messageAccountIsnotVerified"
when I try to use comparison in postman tets script and compare the message with the expected string is working fine:
pm.test("test", function () {
var jsonData = pm.response.json();
pm.expect(jsonData.errorCode).to.eql(1000);
pm.expect(jsonData.errorDescription).to.eql("Account is not verified by Admin!");
});
But When I try to save the String text "Account is not verified by Admin!" in a variable named: messageAccountIsnotVerified
and try to make the same comparison
pm.test("test", function () {
var jsonData = pm.response.json();
pm.expect(jsonData.errorCode).to.eql(1000);
pm.expect(jsonData.errorDescription).to.eql("messageAccountIsnotVerified");
});
or
pm.test("test", function () {
var jsonData = pm.response.json();
var message = pm.environment.get("messageAccountIsnotVerified");
pm.expect(jsonData.errorCode).to.eql(1000);
pm.expect(jsonData.errorDescription).to.eql(message);
});
it failed with error:
test | AssertionError: expected 'Account is not verified by Admin!' to deeply equal 'messageAccountIsnotVerified'
Can someone explain to me
1. what does the "deeply equal" mean and
2. what do I wrong and
3. how can I use the assertion by using the variable
Thanks for any Hint
Just additional Info: I have the same issue when I compare email with
# sign in another message - so I assume may be something to do with special chars
You need to get the variable in the following way:
pm.expect(jsonData.errorDescription).to.deep.equal(pm.environment.get("messageAccountIsnotVerified"))
.to.deep.equal can be used to reference something further down in a nested object.
Add .deep earlier in the chain to use deep equality instead. See the deep-eql project page for info on the deep equality algorithm: https://github.com/chaijs/deep-eql.
Looking at the response body you posted { "errorCode": 1000, "errorDescription": "Account is not verified by Admin!" }, I don't see a problem with the first test but for it to complain about deep equal then this response is probably no exactly as you posted.
You could reduce this all down again if you wanted too:
pm.test("test", () => {
pm.expect(pm.response.json()).to.deep.equal({"errorCode": 1000, "errorDescription": "Account is not verified by Admin!"})
});
That test would do the same as above.
let string = pm.response.json()
pm.expect(string).to.equal("String from Response")
I want to use regex to find records that match certain pattern on Express.js using MongoDB.
Here is my code
var urlList = [];
var db = req.db;
var collection = db.get('project');
var regex = '/^'+url+'/';
console.log('regex = '+regex);
collection.find({url: { $regex: regex, $options: 'i' }},function(err,list){
console.log('length = '+list.length);
var arrayUrl = [];
for (var i=0;i<list.length;i++){
console.log(list[i].url);
arrayUrl.push(list[i].url);
}
});
But I got list.length = 0 although the database contains the records that match the pattern for sure.
Using the following command on cmd
db.project.find({url:{$regex:/^Projek-1/,$options: 'i'}});
I got the results I want.
How to use regex on express.js to find matched records in MongoDB database?
First, you don't really need to use $regex, you'll do fine with url: /foobar/i.
Anyway, the problem is that you are not creating a proper RegExp object, only a string that looks like one. Use a proper one by creating a new instance of RegExp
Example:
var re = new RegExp("^" + url);
...
find({url: re})
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.*' }});
// ex: http://example.com/john_smith
app.get('/^(a-z)_(0-9)', function(req, res) {
res.send('user');
});
// ex: http://example.com/john_smith/messages/1987234
app.get('/^(a-z)_(0-9)/messages/:id', function(req, res) {
res.send('message');
});
I wrote the above code for an app that I want to pass a username as a url variable to node.js like I would do: $username = $_GET['username']; in PHP. I'm not too good at writing regular expressions so I wanted to see if anyone could set me on the right track. Thanks in advance.
From your requirement it doesn't seem like you need a regular expression. Just use a a variable in your rule, like below:
// Grabs whatever comes after /user/ and maps it to req.params.id
app.get('/user/:id', function (req, res) {
var userId = req.params.id;
res.send(userId);
});
If you want to have better control, you could use a regular expression. To grab things you are interested in from the expression, use a capture group (which are typically expressed as a set of matching parenthesis):
// Grabs the lowercase string coming after /user/ and maps it to req.params[0]
app.get(/^\/user\/([a-z]+)$/, function (req, res) {
var userId = req.params[0];
res.send(userId);
});
A little off topic, but here's a really good intro to express.js that will help you understand it better (including how the routes work):
http://evanhahn.com/understanding-express-js/
You're looking for req.params, which is an array of all of the capture groups in the regex.
The capture groups start at 1; req.params[0] is the entire match.
