問題描述

好的，我已經找遍了這個.基本上我們使用的是跨域請求的 $http 請求.我們的服務器允許域，當請求返回 200 時，一切正常.但是，無論何時我們的服務器返回一個錯誤，500、401 等等，Angular 都會認為這是一個 CORS 問題.

Okay, I've looked all over for this. Basically we're using $http request that ARE cross domain requests. Our server allows the domain and when a request returns 200, everything is OK. However, anytime our server returns an error, 500, 401, whatever, Angular thinks it's a CORS issue.

我使用 Fiddler 調試了響應以驗證我的服務器正在返回 500，但 Angular 會阻塞它.

I debugged the response with Fiddler to verify my server IS returning a 500, yet Angular chokes on it.

這是請求:

       var params = {
            url: "fakehost/example",
            method: 'GET',
            headers: {
                "Authorization": "Basic encodedAuthExample"
            }
        };

       $http(params).then(
            function (response) { // success 

            },
            function (error) { // error 
                 // error.status is always 0, never includes data error msg
            });

然后在控制臺中，我會看到這個:

Then in the console, I will see this:

XMLHttpRequest 無法加載 fakehost/example.請求的資源上不存在Access-Control-Allow-Origin"標頭.因此，Origin 'mylocalhost:5750' 不允許訪問.

XMLHttpRequest cannot load fakehost/example. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'mylocalhost:5750' is therefore not allowed access.

然而，在提琴手中，真正的反應是:

Yet, in fiddler, the true response is:

HTTP/1.1 500 Internal Server Error
Cache-Control: no-cache
Pragma: no-cache
Content-Type: application/json; charset=utf-8
Expires: -1

{"errorId":null,"errorMessage":"Index was outside the bounds of the array.","errorDescription":"Stack trace here"}

我正在使用 AngularJS v1.2.16

I'm on AngularJS v1.2.16

推薦答案

我想我找到了答案，看起來你必須在你的 asp.net 管道中注入正確的 CORS 標頭，如上所述 這里.

I think I found an answer, looks like you will have to inject in your asp.net pipeline the correct CORS headers, as mentioned here.
