从 jquery $.ajax 到 angular $http

The AngularJS way of calling $http would look like:

$http({
    url: "http://example.appspot.com/rest/app",
    method: "POST",
    data: {"foo":"bar"}
}).then(function successCallback(response) {
        // this callback will be called asynchronously
        // when the response is available
        $scope.data = response.data;
    }, function errorCallback(response) {
        // called asynchronously if an error occurs
        // or server returns response with an error status.
        $scope.error = response.statusText;
});

or could be written even simpler using shortcut methods:

$http.post("http://example.appspot.com/rest/app", {"foo":"bar"})
.then(successCallback, errorCallback);

有很多事情需要注意:

• AngularJS版本更简洁(特别是使用.post()方法)
• AngularJS将负责将JS对象转换为JSON字符串，并设置标题(可自定义)
• 回调函数分别命名为success和error(也请注意每个回调函数的参数)——在angular v1中不推荐使用.5.
• use then function instead.

The above is just a quick example and some pointers, be sure to check AngularJS documentation for more: http://docs.angularjs.org/api/ng.$http
