我有客户端和服务器在不同的端口上运行.服务器正在运行 Web 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 Microsoft ASP.NET Web API Cross-Origin Support package 和在 WebApiConfig.cs 中启用它.它给了我 EnableCors() 函数,所以包安装正确.
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在WebApiConfig.cs中的Register()函数:
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 请求工作正常.但是在发送 POST 时,我得到以下信息:
GET requests work fine. But when sending POST, I get the following:
OPTIONS localhost:19357/api/v1/rooms? 404 (Not Found) angular.js:10159 OPTIONS localhost:19357/api/v1/rooms? Origin localhost:8000 is not allowed by Access-Control-Allow-Origin. angular.js:10159 XMLHttpRequest cannot load localhost:19357/api/v1/rooms. Origin localhost:8000 is not allowed by Access-Control-Allow-Origin.根据 Fiddler 的说法,它只发送 OPTIONS 请求.之后它不会发出 POST.
According to Fiddler it only sends the OPTIONS request. It doesn't issue the POST afterwards.
所以我猜WebApiConfig.cs中的config.EnableCors(cors);没有做任何事情,这导致服务器拒绝客户端/浏览器发送 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.
你知道如何解决这个问题吗?
Do you have any idea how to solve this problem?
编辑 05.09.13这已在 5.0.0-rtm-130905 中修复
EDIT 05.09.13 This has been fixed in 5.0.0-rtm-130905
推荐答案我肯定遇到了这个问题 带有属性路由.问题是已修复 5.0.0-rtm-130905.但是,您仍然可以尝试 nightly builds 肯定会有修复.
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.
要将 nightlies 添加到 NuGet 包源,请转到 Tools ->库包管理器 ->包管理器设置并在 Package Sources 下添加以下 URL:myget/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: myget/F/aspnetwebstacknightly
