对于重定向到https://login.microsoftonline.com/的请求，“没有'Access-Control-Allow-Origin'标头存在” [英] “No 'Access-Control-Allow-Origin' header is present” for redirected request to https://login.microsoftonline.com/

问题描述

我正在尝试获取访问码的响应并得到：

I'm trying to get response with an access code and getting:

XMLHttpRequest无法加载 h ...：// login.microsoftonline.com/d331431b-899c-4666-8094-e82e6bfc3964/oaut...auth%2faad&scope=user_impersonation&state=033f4ad89a574135884fd3a03c1743ab。所请求的资源上没有 Access-Control-Allow-Origin标头。因此，不允许访问源' http：// localhost：23589 。

使用了来自 ServiceStack，CORS和OPTIONS的所有建议（无Access-Control-Allow-Origin标头）讨论：

已添加：

Plugins.Add(new CorsFeature(new[] { "http://localhost/", "http://localhost:23589" },
            allowCredentials: true,
            allowedHeaders: "Content-Type, Allow, Authorization"));

甚至：

PreRequestFilters.Add((httpReq, httpRes) =>
{
     //if (httpReq.Verb == "OPTIONS")
     //{
     //    var origin = httpReq.Headers.Get("Origin");
     string origin = httpReq.Headers.Get("Origin");
     httpRes.AddHeader(HttpHeaders.AllowOrigin,  "*");
     httpRes.EndRequest();
     // }
});

仍然没有运气。我们正在使用ServiceStack版本4.0.56

Still no luck. We are using ServiceStack version 4.0.56

推荐答案

问题是因为您要调用 / api / auth / aad 通过Ajax进行OAuth路由，而不是直接链接到您的页面中。

The issue is because you're trying to call the /api/auth/aad OAuth route via Ajax instead of linking to it directly in your page.

您无法通过Ajax调用AAD OAuth路由，因为它重定向到的URL用于捕获客户端授权（ https：// login.microsoftonline.com /..）不允许您看到的错误中指出的CORS。

You can't call the AAD OAuth route via Ajax since the url it redirects to that's used to capture the clients authorization (https://login.microsoftonline.com/..) doesn't allow CORS as indicated in the error that you're seeing.

这是'一个ServiceStack CORS问题，因为它与本地API托管在同一域中，所以您不需要与本地API进行对话（即 http：// localhost：23589 ） HTML页面。使用Ajax访问外部资源时，需要CORS（跨域资源共享）域（即 https://login.microsoftonline.com/..$code>），因为它不允许CORS不允许您通过Ajax访问该URL。

This isn't a ServiceStack CORS issue which you don't need in order to talk to your local API's (i.e. http://localhost:23589) since its hosted in the same domain as the HTML page. CORS (Cross-origin resource sharing) is needed when using Ajax to access a resource outside of the domain (i.e. https://login.microsoftonline.com/..) which since it doesn't allow CORS will not let you access that url via Ajax.
