启用网页API 2 CORS [英] Enable CORS in Web API 2

问题描述

我有客户端和服务器上的不同端口上运行。服务器运行的是网络API 2（V5.0.0-RC1）

I have client and a server running on different ports. The server is running Web API 2 (v5.0.0-rc1).

我尝试安装了的Microsoft ASP.NET Web API跨域支持包和使它在​​ WebApiConfig.cs 。它给我的 EnableCors（）功能，所以包被正确安装。

I tried installing the Microsoft ASP.NET Web API Cross-Origin Support package and enabled it in WebApiConfig.cs. It gives me the EnableCors() function, so the package was installed correctly.

在这里，你可以看到我的寄存器（）功能 WebApiConfig.cs ：

Here you can see my Register() function in WebApiConfig.cs:

public static void Register(HttpConfiguration config)
{
    config.MapHttpAttributeRoutes();

    var cors = new EnableCorsAttribute("*", "*", "*");
    config.EnableCors(cors);
}

GET 请求正常工作。但是，当发送 POST ，我得到以下内容：

GET requests work fine. But when sending POST, I get the following:

OPTIONS http://localhost:19357/api/v1/rooms? 404 (Not Found) angular.js:10159
OPTIONS http://localhost:19357/api/v1/rooms? Origin http://localhost:8000 is not allowed by Access-Control-Allow-Origin. angular.js:10159
XMLHttpRequest cannot load http://localhost:19357/api/v1/rooms. Origin http://localhost:8000 is not allowed by Access-Control-Allow-Origin.

据提琴手只发送选项请求。它不发出 POST 之后。

所以我猜 config.EnableCors（CORS）; 在 WebApiConfig.cs 不是做任何事情，这导致服务器拒绝客户端/浏览器发送一个 POST 请求。

So I'm guessing the config.EnableCors(cors); in the WebApiConfig.cs isn't doing anything, which leads to the server denying the client/browser to send a POST request.

你有任何想法如何解决这个问题？

Do you have any idea how to solve this problem?

推荐答案

我最肯定打这个问题带属性的路由。 问题 WAS <一个href=\"https://aspnetwebstack.$c$cplex.com/SourceControl/changeset/6eb7f13ca6158800a18dcb299dca481277513cbd\">fixed为5.0.0-RTM-130905的。但尽管如此，你可以尝试在每晚构建其中大部分肯定会修复

I'm most definitely hitting this issue with attribute routing. The issue was fixed as of 5.0.0-rtm-130905. But still, you can try out the nightly builds which will most certainly have the fix.

要Nightlies版添加到您的NuGet软件包源，转到工具 - ＆GT;图书馆软件包管理器 - ＆GT; ：包管理器设置，并在软件包源添加以下网址http://myget.org/F/aspnetwebstacknightly

To add nightlies to your NuGet package source, go to Tools -> Library Package Manager -> Package Manager Settings and add the following URL under Package Sources: http://myget.org/F/aspnetwebstacknightly
