我有一段jQuery代码可以很好地跨源:

jQuery.ajax({
    url: "http://example.appspot.com/rest/app",
    type: "POST",
    data: JSON.stringify({"foo":"bar"}),
    dataType: "json",
    contentType: "application/json; charset=utf-8",
    success: function (response) {
        console.log("success");
    },
    error: function (response) {
        console.log("failed");
    }
});

但我想将这个转换为Angular.js代码

$http({
    url: "http://example.appspot.com/rest/app",
    dataType: "json",
    method: "POST",
    data: JSON.stringify({"foo":"bar"}),
    headers: {
        "Content-Type": "application/json; charset=utf-8"
    }
}).success(function(response){
    $scope.response = response;
}).error(function(error){
    $scope.error = error;
});

调用$ http的AngularJS方法如下所示:

$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;
});

或者可以更简单地编写:

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

以在AngularJs中使用http服务来实现ajax请求,这有助于从远程服务器读取/加载数据。

下面列出了$ http服务方法,

 $http.get()
 $http.post()
 $http.delete()
 $http.head()
 $http.jsonp()
 $http.patch()
 $http.put()

其中一个例子:

    $http.get("sample.php")
        .success(function(response) {
            $scope.getting = response.data; // response.data is an array
    }).error(){

        // Error callback will trigger
    });
