AngularJS - $ HTTP GET返回错误状态为0？ [英] AngularJS - $http get returns error with status 0?

问题描述

我在这我想从一个服务器$ HTTP GET XML数据的应用程序AngularJS说的 http://example.com/a/b/c/d/getDetails?fname=abc&lname=def （这时候通过手动访问进入在浏览器中的链接显示了XML文件的树结构）。

I've an AngularJS application in which I'm trying to get an XML data with $http get from a server say http://example.com/a/b/c/d/getDetails?fname=abc&lname=def (this when accessed manually by entering the link in a browser shows a tree structure of the XML file).

当我从该链接运行应用程序的数据并不牵强。相反，它显示一个错误的状态0

When I run the application the data from that link is not fetched. Instead its showing an error with status 0.

//url = http://example.com/a/b/c/d/getDetails?fname=abc&lname=def
$http.get(url).success(function (data){
                alert("Success");
                deferred.resolve(data);
            }).error(function (data, status){
                console.log("Error status : " + status);
            });

我不知道为什么$ http.get出现故障并以误差函数返回状态0。

I'm not sure why the $http.get fails and goes to the error function returning status 0.

但是，如果我通过一个URL，其​​中有一个JSON对象的本地服务器，它的工作原理。

But if I pass an URL to the local server which has a JSON object, it works.

是因为我试图访问从不同的域XML文件（CORS问题？），还是别的什么问题？

Is the problem because of me trying to access the XML file from a different domain(CORS issue?) or something else?

请帮我出！

推荐答案

您有 HTTP访问控制（CORS）问题。

回答您的REST请求必须包括CORS指定的头文件，以便服务器允许角正常消耗的响应。从本质上讲，这意味着包括在响应访问控制允许来源头，指定从哪里请求来自，被允许的服务器。 （参考）

The server answering your REST requests MUST include the headers specified by CORS in order to allow Angular to consume properly the response. Essentially this means including the Access-Control-Allow-Origin header in your response, specifying the servers from where the request comes from, that are allowed. (ref)

有是指令角允许一个获取/设置用来保证白名单和黑名单用于采购角模板的URL是安全的。

There is directive Angular allows one to get/set the whitelists and blacklists used to ensure that the URLs used for sourcing Angular templates are safe.
