发出 http get 请求并访问我得到的数据

Question

In my app, I'm issuing get request to retrieve JSON from my server.

        $http.get('http://localhost:3000/documents/2.json')
            .success(
                    function(success){
                        console.log("Success");
                    })
            .error(
                    function(error){
                            console.log("error has occurred")
        });

Right now, I do successfully get 200 response, but I'm not sure how to access the json file I'm getting from the URL in my web app. I assume there's gotta be something like function(JSONData) but not sure how to implement it in my function above.

I'm issuing this in client side(Written in Angular) and getting the data from the server(written in Rails). My front end (in Angular) is part of Rails app now.

Answer 1

MAJOR EDIT:

This is the version (1.4.9) that the OP is using.

In the AngularJS $http Documentation v1.4.9 you get a sample script of what you are trying to do.

// Simple GET request example:
$http({
  method: 'GET',
  url: '/someUrl'
}).then(function successCallback(response) {
    // this callback will be called asynchronously
    // when the response is available
  }, function errorCallback(response) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
  });

inside succes call back write

console.log(success)

so your code must look like this

$http.get('http://localhost:3000/documents/2.json')
            .success(
                    function(success){
                        console.log("Success");
                        console.log(success);
                    })
            .error(
                    function(error){
                            console.log("error has occurred")
        });

parameter(success) in function is data, that you receive from server, instear of success you can write anything you want .. usually i write data .. so in my case it will be function (data)
