Start a Datafeed on button press... help please!!

[NeilJordan]

Hi Folks,

I'm trying to create a simple custom object with a button to launch a datafeed but I can't seem to get it to work at all after many hours scratching my head!

This is my code. Could someone please advise where I'm going wrong. (please ignore all the alerts as I tried to figure out where the code was getting to. I always see the "failed to launch feed!" alert.

Thanks

Neil.

<button type="button" ="trigger()">Create Finding</button>

<script type="text/javascript">
     var authstr = '{"InstanceName":"50000","Username":"apisvintake","UserDomain":"","Password":"xxxxxx"}';
     var authUrl = 'https://<server>/archer/api/core/security/login';
     var feedUrl = 'https://<server>/archer/api/core/datafeed/execution';
     var feedstr = '{"DataFeedGuid":"87BB24F5-A66F-498F-B7E6-00F586A74776","IsReferenceFeedsIncluded":false}';
     function trigger() {
    $.ajax
    ({
        type: "POST",
        url: authUrl,
        contentType: "application/json", 
        dataType: "json",
        data:authstr,
        success: function (result) {
               var stringresult = JSON.stringify(result);
               var sesstok = 'Archer session-id=' + stringresult.substr(stringresult.search("SessionToken")+15,32);
            //;
               $.ajax
               ({
                    type: "POST",
                    url: feedUrl,
                    contentType: "application/json",
                    processData: false,
                    dataType: "json",
                    data : feedstr,
                    beforeSend : function( xhr ) {
                              xhr.setRequestHeader( "Authorization", sesstok );
                              xhr.setRequestHeader( "content-Type", "application/json" );
                              xhr.setRequestHeader( "Accept", "application/json,text/html,application/xhtml+xml,application/xml;q=.9,*/*;q=0.8" );
                              alert(sesstok);
                    },
                    success: function (runfeed) {
                         var feedresult = JSON.stringify(runfeed);
                         alert("Feed success");
                    },
                    error: function(errormsg) {
                         alert("failed to launch feed!");     
                         alert(JSON.stringify(errormsg.responseXML));
                    }
               });
        },
          error: function(errMsg) {
               
alert("outside func");
alert(JSON.stringify(errMsg.responseXML));
    }
    });
alert("button press finished");     
};

Neil, why reinvent the wheel

Thanks David. I saw that one, but didn't want to give the group of users that need to see the button the rights to see the datafeed manager. I even tried to add the authorization section into that one but that code was a real mess!!!

[DavidPetty · Accepted solution]

Ahh, ok.  Though I'd advised against this being the credentials are store in clear text in the browser and any curious user could use that information to log into Archer.

With that said

You need to add this to your two ajax calls, after lines 14 and 26

headers: {
 'x-csrf-token': (window.sessionStorage) ? window.sessionStorage.getItem("x-csrf-token") : csrfToken = parent.parent.ArcherApp.globals['xCsrfToken']
},‍‍‍

Also some feedback, you can replace lines 5 and 6 with:

var baseURL = window.location.protocol + '//' + window.location.host + parent.parent.ArcherApp.globals['baseUrl'];‍

then adjust line 12 with

baseURL + '/api/core/security/login'‍

then the same for line 23 with

baseURL + '/api/core/datafeed/execution'‍

This would at least save you the pain of updating the custom object when moving the application from one instance to the next.

You Sir, are a genius!!!

Worked a treat. Thanks!
