AngularJS $http 错误函数从未被调用 [英] AngularJS $http error function never called

问题描述

我有那个简单的代码:

$http.get("/api/test")
    .success(function (data, status, headers, config) {
        console.log(data);
        return data;
    }).error(function (data, status, headers, config) {
        alert("error");
        return status;
});

它工作正常，但从未调用错误函数，即使我从服务器返回 404(未找到)...在这种情况下，它会调用 status = 404...

It works fine, but the error function is never called, even when I return a 404 (Not Found) from the server... In that case it calls that 'success' function with status = 404...

这样对吗?

谢谢

推荐答案

问题在于您的网络服务器，它将 content-length 设置为 0，这意味着这是一个有效值，正如您在 HTTP/1.1 规范.

The problem is your webserver, it is setting content-length to 0 that means that is a valid value as you can see on HTTP/1.1 specification.

我还在 JSFiddle 上做了一个例子，展示了错误和成功的例子.请参阅此处.

Also I made a example on JSFiddle showing the error and success examples. See here.
