Question

The function JSON.parse appears to be malfunctioning within the code, yet it operates smoothly when executed in

I am facing an issue with my Angular $http post service that communicates with a WCF service. The success handler in the http post is as follows:

.success(function (data) {
    var response = JSON.parse(data);
    var tsValid = response.Outcome;
    deferred.resolve(tsValid);
}

However, I always get 'undefined' for tsValid. Upon adding some console logs, I noticed that the "data" variable looks like this:

 "{\"Message\":\"Valid Timestamp\",\"Reference\":\"CheckTimestamp:Completed\",\"Outcome\":true,\"Data\":null,\"MessageCount\":0,\"MessageGUID\":null}"

After parsing, "response" appears as:

{"Message":"Valid Timestamp","Reference":"CheckTimestamp:Completed","Outcome":true,"Data":null,"MessageCount":0,"MessageGUID":null}

It seems like all JSON.parse did was remove the escape characters. When attempting to access response.Outcome, it returns undefined.

Curiously, manually parsing the "data" variable using JSON.parse in a command prompt works correctly and allows me to access response.Outcome.

Any suggestions on why JSON.parse isn't functioning properly within the success handler?

EDIT - I have updated the console output to eliminate the "data:" and "response:" tags that were initially included by me for identification purposes.

Answer №1

When it comes to the response, make sure you access the key data by using the following code:

var tsValid = response.data.Outcome;

UPDATE

Please execute this code snippet and share the logs with me.

.success(function (data) {
    console.log(data);
    var response = JSON.parse(data);
    console.log(response);
    var tsValid = response.Outcome;
    deferred.resolve(tsValid);
}
