I'm trying to call a web API.
The parameter needs to include double-quoted string but not allowed to have backslash.
So far, I tried and have the following code.
let method = "helloWorld"
let parameters = "param1=test¶m2={keywords:[" + "\"Hello\"" + "],type:" + "\"General\"" + "}"
let convertedParameters = parameters.replacingOccurrences(of: "\\", with: "")
let path = baseURL + method + "?" + convertedParameters
let response = Alamofire.request(path, method: .get)
.responseJSON()
This gives an error at backslash(escape string).
Finally, the link looks like the following.
https://example.com/api/hellowWorld?param1=test¶m2={keywords:[\"Hello\"],type:\"General\"}
Then, I remove the backslashes manually, paste it in web browser and it works properly.
https://example.com/api/hellowWorld?param1=test¶m2={keywords:["Hello"],type:"General"}
It is pretty hard to request the change of web API and I want to treat this tiny problem on my side.
Is it technically possible?
I appreciate if someone helps me.

I looking for regular expression to use in my javascript code, which give me last part of url without parameters if they exists - here is example - with and without parameters:
https://scontent-fra3-1.xx.fbcdn.net/v/t1.0-9/14238253_132683573850463_7287992614234853254_n.jpg?oh=fdbf6800f33876a86ed17835cfce8e3b&oe=599548AC
https://scontent-fra3-1.xx.fbcdn.net/v/t1.0-9/14238253_132683573850463_7287992614234853254_n.jpg
In both cases as result I want to get:
14238253_132683573850463_7287992614234853254_n.jpg
Here is this regexp
.*\/([^?]+)
and JS code:
let lastUrlPart = /.*\/([^?]+)/.exec(url)[1];
let lastUrlPart = url => /.*\/([^?]+)/.exec(url)[1];
// TEST
let t1 = "https://scontent-fra3-1.xx.fbcdn.net/v/t1.0-9/14238253_132683573850463_7287992614234853254_n.jpg?oh=fdbf6800f33876a86ed17835cfce8e3b&oe=599548AC"
let t2 = "https://scontent-fra3-1.xx.fbcdn.net/v/t1.0-9/14238253_132683573850463_7287992614234853254_n.jpg"
console.log(lastUrlPart(t1));
console.log(lastUrlPart(t2));
May be there are better alternatives?
You could always try doing it without regex. Split the URL by "/" and then parse out the last part of the URL.
var urlPart = url.split("/");
var img = urlPart[urlPart.length-1].split("?")[0];
That should get everything after the last "/" and before the first "?".
I have integrated oAuth2 (Facebook, LinkedIn, etc) with my XPages app to allow for authentication to easily add comments (response docs). When a user authenticates, it has to redirect to the facebook/linkedin page, then return to complete the document creation. I use the state variable to do this, and pass it in the querystring of the url. When the page reloads and sees the state variable, it calls a "beforePageLoad" event and creates the response document if the user authenticated and has the correct state document.
My problem is when there is already a state parameter in the querystring. I want to replace the value, not add it to the end. I use a solution here from stackOverflow by ellemayo called updateQueryStringParameter. When I call it from my beforePageLoads it runs, but never replaces the parameter, it only appends it to the end. I end up with ...&state=E5A&state=E5F
I have a feeling that it is in the line,
return uri.replace(re, '$1' + key + "=" + value + '$2');
I can write the code using #ReplaceSubstring(), etc, but want to know if there are problems running regex in XPages SSJS. I read on Lotus.com that
A Regular Expression can be specified as Server-side, which uses the
Java (java.util.regex) API or Client-side, which uses the browser
JavaScript Regular Expression Engine. Client-side and Server-side
Regular Expression syntax is similar, but there are differences that a
user must be aware of.
Should I avoid regex in XPages SSJS ? I have it working extensively in client and in some field validations on the XPage itself.
Here is the call to the function:
if(#Contains( qString,"state=")){
qString=updateQueryStringParameter(qString, "state", linkDoc.getNoteID() );
}else{
qString="?"+qString+"&state=" + linkDoc.getNoteID()
}
the function:
function updateQueryStringParameter(uri, key, value) {
var re = new RegExp("([?&])" + key + "=.*?(&|$)", "i");
var separator = uri.indexOf('?') !== -1 ? "&" : "?";
if (uri.match(re)) {
// I also tried --> if (re.test(uri)) {
return uri.replace(re, '$1' + key + "=" + value + '$2');
}
else {
return uri + separator + key + "=" + value;
}
}
It was not an XPage or Regex problem. I was using the querystring provided by Domino the excludes the "?" as part of the querystring. when I send "?" + qString to the function, it works. Regex needed to know where to start looking, thus it never found the start of the query string.
I'm looking to match a part of several HTML files that get passed into a loop in an ASP file and then return that part of the HTML files to include in my output. Here's my code so far:
<%for i=0 to uBound(fileIDs) ' fileIDs is an array of URLs
dim srcText, outText, url
Set ex = New RegExp
ex.Global = true
ex.IgnoreCase = true
ex.Pattern = "<section>[\S\s]+</section>" ' This finds the HTML I want
url = fileIDs(i)
Set xmlhttp = CreateObject("MSXML2.ServerXMLHTTP")
xmlhttp.open "GET", url, false
xmlhttp.send ""
srcText = xmlhttp.responseText
outputText = ex.Execute(mediaSrcText) ' I expect this to be the HTML I want
Response.Write(outputText.Item(0).Value) ' This would then return the first instance
set xmlhttp = nothing
next %>
I've tested the regular expression on my files and it's matching the parts that I want it to.
when I run the page containing this code, I get an error:
Microsoft VBScript runtime error '800a01b6'
Object doesn't support this property or method
on the line with ex.Execute. I've also tried ex.Match, but got the same error. So I'm clearly missing the proper method for returning the match so I can write it out into the file. What is that method? Or am I approaching the problem from the wrong direction?
Thanks!
You need a Set when you're assigning outputText:
Set outputText = ex.Execute(mediaSrcText)
I should probably also say that you really shouldn't be using regular expressions to attempt to parse HTML, although I don't know enough about the context to offer more specific advice.
I am hoping someone can help get me in the right direction...
I am using Powerbuilder 12 Classic and trying to consume a Oracle CRM OnDemand web service.
Using Msxml2.XMLHTTP.4.0 commands, I have been able to connect using https and retrieve the session id, which I need to send back when I invoke the method.
When I run the code below, I get the SBL-ODU-01007 The HTTP request did not contain a valid SOAPAction header error message. I am not sure what I am missing??
OleObject loo_xmlhttp
ls_get_url = "https://secure-ausomxxxx.crmondemand.com/Services/Integration?command=login"
try
loo_xmlhttp = CREATE oleobject
loo_xmlhttp.ConnectToNewObject("Msxml2.XMLHTTP.4.0")
loo_xmlhttp.open ("GET",ls_get_url, false)
loo_xmlhttp.setRequestHeader("UserName", "xxxxxxx")
loo_xmlhttp.setRequestHeader("Password", "xxxxxxx")
loo_xmlhttp.send()
cookie = loo_xmlhttp.getResponseHeader("Set-Cookie")
sesId = mid(cookie, pos(cookie,"=", 1)+1, pos(cookie,";", 1)-(pos(cookie,"=", 1)+1))
ls_post_url = "https://secure-ausomxxxx.crmondemand.com/Services/Integration/Activity;"
ls_response_text = "jsessionid=" + sesId + ";"
ls_post_url = ls_post_url + ls_response_text
loo_xmlhttp.open ("POST",ls_post_url, false)
loo_xmlhttp.setRequestHeader("COOKIE", left(cookie,pos(cookie,";",1)-1) )
loo_xmlhttp.setRequestHeader("COOKIE", left(cookie,pos(cookie,";",1)-1) )
ls_post_url2 = "document/urn:crmondemand/ws/activity/10/2004:Activity_QueryPage"
loo_xmlhttp.setRequestHeader("SOAPAction", ls_post_url2)
loo_xmlhttp.send()
ls_get_url = "https://secure-ausomxxxx.crmondemand.com/Services/Integration?command=logoff"
loo_xmlhttp.open ("POST",ls_get_url, false)
loo_xmlhttp.send()
catch (RuntimeError rte)
MessageBox("Error", "RuntimeError - " + rte.getMessage())
end try
I believe you are using incorrect URL for Login and Logoff;
Here is the sample:
https://secure-ausomxxxx.crmondemand.com/Services/Integration?command=login
https://secure-ausomxxxx.crmondemand.com/Services/Integration?command=logoff
Rest of the code looks OK to me.
I have run into similar issues in PB with msxml through ole. Adding this may help:
loo_xmlhttp.setRequestHeader("Content-Type", "text/xml")
you need to make sure that the your value for ls_post_url2 is one of the values that is found in the wsdl file. Just search for "soap:operation soapAction" in the wsdl file to see the valid values for SOAPAction.
I have a URL validation method which works pretty well except that this url passes: "http://". I would like to ensure that the user has entered a complete url like: "http://www.stackoverflow.com".
Here is the pattern I'm currently using:
"^(https?://)"
+ "?(([0-9a-z_!~*'().&=+$%-]+: )?[0-9a-z_!~*'().&=+$%-]+#)?" //user#
+ #"(([0-9]{1,3}\.){3}[0-9]{1,3}" // IP- 199.194.52.184
+ "|" // allows either IP or domain
+ #"([0-9a-z_!~*'()-]+\.)*" // tertiary domain(s)- www.
+ #"([0-9a-z][0-9a-z-]{0,61})?[0-9a-z]\." // second level domain
+ "[a-z]{2,6})" // first level domain- .com or .museum
+ "(:[0-9]{1,4})?" // port number- :80
+ "((/?)|" // a slash isn't required if there is no file name
+ "(/[0-9a-z_!~*'().;?:#&=+$,%#-]+)+/?)$"
Any help to change the above to ensure that the user enters a complete and valid url would be greatly appreciated.
Why not use a urlparsing library? Let me list out some preexisting url parsing libraries for languages:
Python: http://docs.python.org/library/urlparse.html
Perl: http://search.cpan.org/dist/URI/URI/Split.pm
Ruby: http://www.ensta.fr/~diam/ruby/online/ruby-doc-stdlib/libdoc/uri/rdoc/classes/URI.html#M001444
PHP: http://php.net/manual/en/function.parse-url.php
Java: http://download.oracle.com/javase/1.4.2/docs/api/java/net/URI.html#URI(java.lang.String)
C#: http://msdn.microsoft.com/en-us/library/system.uri.aspx
Ask if I'm missing a language.
This way, you could first parse the uri, then check to make sure that it passes your own verification rules. Here's an example in Python:
url = urlparse.urlparse(user_url)
if not (url.scheme and url.path):
raise ValueError("User did not enter a correct url!")
Since you said you were using C# on asp.net, here's an example (sorry, my c# knowledge is limited):
user_url = "http://myUrl/foo/bar";
Uri uri = new Uri(user_url);
if (uri.Scheme == Uri.UriSchemeHttp && Uri.IsWellFormedUriString(user_url, UriKind.RelativeOrAbsolute)) {
Console.WriteLine("I have a valid URL!");
}
This is pretty much a FAQ. You could simply try a search with [regex] +validate +url or just look at this answer: What is the best regular expression to check if a string is a valid URL
I use this regex. It works fine for me.
/((([A-Za-z]{3,9}:(?://)?)(?:[-;:&=+\$,\w]+#)?[A-Za-z0-9.-]+|(?:www.|[-;:&=+\$,\w]+#)[A-Za-z0-9.-]+)((?:/[+~%/.\w-]*)?\??(?:[-+=&;%#.\w])#?(?:[\w]))?)/
