Trying to create a patient by REST module using POST

[Juan Camilo Vanegas Serna]

Hi everybody. I am trying to figure out how to use correctly the REST web service module. I am working on HTML/CSS and JS to run AJAXpetition to my localhost.

I already read from the wiki page that I need to send the identifiers (as a Array) and the person (as a object). Here is how I organized my JSON:

var data ={"identifiers":[{ "identifier":"DFGHA-3",

                               "identifierType":"8d79403a-c2cc-11de-8d13-0010c6dffd0f",

                               "location":"8d79403a-c2cc-11de-8d13-0010c6dffd0f",

                             "preferred":true

                            }],

              "person":{"gender":"M",

                      "birthdate":"1990-10-29",

                      "names":[{"givenName":"Pepito",

                                       "familyName":"Perez"

                                          }]

                         }

};

And the AJAX is organized:

$.ajax({

    type: 'POST',

    url: 'http://localhost:8080/openmrs/ws/rest/v1/patient',

    data: data,

    contentType: 'application/json; charset=UTF-8',

        dataType: 'json',

     xhrFields:{

             withCredentials: true

     },

     beforeSend: function (xhr){

              xhr.setRequestHeader('Authorization','Basic '+btoa('admin'+":"+'Admin123'));            

     },

    success: function(data){

          console.log(data);

    },

    error: function(xhr, type){

       console.log('Ajax error!');

    }

});

But when I send my data, I receive: 

{"error":{"message":"Could not read JSON: Unexpected character ('i' (code 105)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')\n at [Source:

I believe i have some problems with my data variable. The server seems to have problems when try to read the JSON, and the problem is with the 'i' from the identifiers. If i change the order, that is, person first and then identifiers, the error change to Could not read JSON: Unexpected character ('p'...

Thanks for any help can give me,

Juan Camilo.

I already find the error. The first one was the uuid for location and identifier_type. This data is: 

"identifierType":"8d793bee-c2cc-11de-8d13-0010c6dffd0f",

"location":"8d6c993e-c2cc-11de-8d13-0010c6dffd0f"

and not

"identifierType":"8d79403a-c2cc-11de-8d13-0010c6dffd0f",

"location":"8d79403a-c2cc-11de-8d13-0010c6dffd0f"

The second was for the process data of AJAX. You need to set to false. So the AJAX finally is:

$.ajax({

 type: 'POST',

 url: 'http://localhost:8080/openmrs/ws/rest/v1/patient',

 processData:false,

 data: JSON.stringify(data),

 contentType: 'application/json;charset=UTF-8',

 dataType: 'json',

     xhrFields:{

             withCredentials: true

          },

          beforeSend: function (xhr){ 

             xhr.setRequestHeader('Authorization','Basic '+btoa('admin'+":"+'Admin123'));           

          },

 success: function(data){

   console.log(data);

 },

 error: function(xhr, type){

   console.log('Ajax error!');

 }

});

I hope this can help someone.

But the error was highly misleading, it should have returned some "identifier type xxx is invalid" message. I think it's worth a ticket.

But that happens, I forgot say the error when  processData is true in AJAX  instead use JSON.stringify. This is the error when you send the JSON without stringify it:
