获得状态-1而不是401 Angularjs [英] getting status -1 instead 401 Angularjs

问题描述

我正在尝试从服务器获得响应。该函数看起来如此：

I'm trying to get a response from server. The function looks so:

function getOverview() {
        var req = {
            method: 'GET',
            url: base,
            headers: {
                'authorization': 'Bearer ' + GottenTokens.getSessionToken()
            }
        };

        return $http(req).then(
            function successCallback(response) {
                return response;
            }, function errorCallback(response) {
                console.log(response);
                return response;
            });
    }

当状态为200时，没有问题，它会返回良好的响应状态200.但是......当状态为401时，它返回状态为-1的响应：

When the status is 200, there's no problem, it returns the good response with status 200. But... when the status is 401, than it returns a response with status -1:

Object {data: null, status: -1, config: Object, statusText: ""}

我试过了在postman中，我看到状态为401，并且在浏览器中也是这样说的：

I was trying it in postman and I saw there's the status 401 and also in browser it says so:

XMLHttpRequest cannot load http://localhost:5000/overview. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access. The response had HTTP status code 401.

这意味着浏览器和邮递员从服务器获取状态，但它不会出现在Angularjs中。我正在尝试这篇文章：捕获Http 401 但它没有帮我。我在工厂中有这个功能。

It means that the browser and postman take the status from server, but it doesn't come in Angularjs. I was trying this post: Capture Http 401 but it doesn't help me. I have that function in a "factory".

顺便说一下，服务器是用akka编写的。我不知道它是否有事可做。以前在NodeJS中，我没有遇到任何问题。因为它在akka我无法获得Angularjs的状态。

By the way, the server is written in akka. I don't know if it has something to do. Before was it in NodeJS and I didn't have problems. Since it's in akka I can't get the status in Angularjs.

有人可以帮帮我吗？

推荐答案

在进行跨站点请求时，服务器必须向ALL响应添加有效的CORS头。这包括401之类的错误响应。

When doing cross-site requests, the server has to add to ALL responses a valid CORS header. This includes error responses like 401.

确保您可以看到Access-Control-Allow-Origin 401回复中的标题，很可能丢失。

Make sure you can see the "Access-Control-Allow-Origin" header in your 401 response, it's most likely missing.
