Angular http service not responding

[shavo007]

Hi,

I have drakov running using grunt on localhost:3000.

[LOG] Setup Route: GET /subscribe Subscribe by email
   Drakov 0.1.8      Listening on port 3000
-- STARTED --

My endpoint I can hit via browser or postman.

Example:

http://localhost:3000/subscribe?id=12345&type=xyz&email=xyz&hv=xyz

But when I try and call the api in angular, in the server console it logs continuously:

[LOG] OPTIONS /subscribe?id=12345&type=xyz&email=xyz&hv=xyz

Code snippet angular:

 $http.get('http://localhost:3000/subscribe?id=12345&type=xyz&email=xyz&hv=xyz', {headers: {
        'Custom-Header': 'a'}})
        .success(function (response) {
          console.log('Response ' + response);
        });

My grunt config:

 grunt.registerTask('mock-api', 'Start drakov server', function() {
    var done = this.async();

    var drakovOptions = {
      sourceFiles: './doc/*.md',
      serverPort: 3000
     // autoOptions: true
      //disableCORS: false
    };

    drakov.run(drakovOptions, function(err){
      console.log('-- STARTED --');
      if (err) {
        throw err;
      }
    });
    done();
  });

NB: My angular app is running on a different port using connect on port 9000.

I have got a bit further but not much!
In the response I added in two headers:

+ Headers

            Access-Control-Allow-Origin: *
            Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept

Angular http service now calls get instead of options but it just keeps looping and inevitably crashes!!!

i think instead of adding in the custom headers to the blueprint file, i need to work out for local development how to host drakov and grunt connect on the same domain (localhost). I think i need a proxy!!!

[yakovkhalinsky]

CORS is enabled by default, so I'm not sure if I can explain why it doesn't respond.

Are you able to post the endpoint snippet from the markdown file?

[shavo007]

Cheers for the reply mate.

This is my code snippet from my .md file.

# Group Subscriptions


## Subscription  [/api/subscribe{?id,type,email,hv}]


+ Parameters
    + id (string, `12345`, required) ... Tracking number(s) [delimiter is ',']
    + type (string, `xyz`, optional) ... the type of the item represented by the id field. If this is populated, id is expected to be a single  track  number.
    + email (string, `z.dead@g.com.au`, optional) ...  the email address to which track advice will be sent
    + hv (string, `xyz`, optional) ... the hash used to validate the id and email address fields



### Subscribe by email [GET]

+ Response 200

    + Headers

            content-type: application/json

    + Body

              {
                  "QueryTrackEventsResponse": {
                      "TrackingResult": {
                          "ReturnMessage": {
                              "Code": "ESB-10000",
                              "Description": "Success"
                          },
                          "TrackingID": "xxx",
                          "ArticleDetails": {
                              "ArticleID": "xxx",
                              "EventNotification": "00",
                              "ProductName": "International",
                              "ClientStatus": "None",
                              "EventCount": 0
                          }
                      }
                  }
              }

In the server log I see:

[LOG] Setup Route: GET /api/subscribe Subscribe by email

I have added in the config to use a connect-proxy.

Once I did this, it resolved the issue!!!

This is a snippet of the proxy config in my gruntFile.js

     proxies: [{
        context: '/api', // the context of the track microservice api
        host: 'localhost', // wherever the data service is running
        port: 3000 // the port that the microservice is running on
      }],

Do you believe I do not need the proxy?

[yakovkhalinsky]

sorry for the late reply, we use Drakov with protractor tests that run static Angular.js interfaces with no need of a proxy.

Maybe the proxy is modifying the headers somehow.

[shavo007]

From what I read, you need a proxy when you are running a back-end server to prevent CORS.

Closing as the above plugin worked for me.
