ServiceStack Cors [英] ServiceStack Cors

问题描述

我正在建立一个项目，并希望实现CORS。它安装在共享的IIS服务器（共享主机）上。

在我的apphost.cs中，根据我在网上找到的几篇文章启用和配置CORS。

  Plugins.Add（new CorsFeature（
 allowedMethods：GET，POST，PUT，DELETE，OPTIONS，
 allowedOrigins：*，
 allowCredentials：true，
 allowedHeaders：content-type，Authorization，Accept））; 
 

我还读到当实现较新的SS API（IService）时，我不得不提供一个钩子'option'call so I added ...

  this.RequestFilters.Add（（httpReq，httpRes，requestDto）=& 
 {
 //发出全局HTTP头后处理请求并关闭响应
 if（httpReq.HttpMethod ==OPTIONS）
 httpRes.EndRequest（）; //添加'using ServiceStack;'
}）; 
  

我可以通过REST控制台调用我的api（chrome addin），但是当我调用ajax请求我收到了405错误。

我查看了此问题，并如上所示实现了它。这个相关的问题不是重复的。  servicestack REST API和CORS  
 
 
 
我正在做的服务调用（POST）是... 
  public object Post（SelectedTroops request）
 {
 return new SelectedTroopsResponse {ArrayOfSelectedTroops = request.ArrayOfSelectedTroops}; 
 
} 
  
如果我遗漏任何可能有帮助的内容，知道。我猜一个旁注问题可能是 - 你怎么有效地跟踪和调试这样的东西？ 
解决方案
您必须使用：
  httpRes.EndRequest（）; 
  
这很重要，它是一个扩展方法。 ServiceStack 命名空间。我建议使用像ReSharper这样的工具，使自动查找和引用扩展方法轻而易举。
 
I am building a project and wish to implement CORS.  It is installed on a shared IIS server (shared hosting).

In my apphost.cs I enable and configure CORS according to several of the articles I find on the web.
Plugins.Add(new CorsFeature(
     allowedMethods: "GET, POST, PUT, DELETE, OPTIONS", 
     allowedOrigins: "*", 
     allowCredentials: true, 
     allowedHeaders: "content-type, Authorization, Accept"));
I also read that when implementing the newer SS API (IService) I had to provide a hook for the 'Options' call so I added...
this.RequestFilters.Add((httpReq, httpRes, requestDto) =>
{
     //Handles Request and closes Responses after emitting global HTTP Headers
     if (httpReq.HttpMethod == "OPTIONS")
         httpRes.EndRequest();  //add a 'using ServiceStack;'
     });
I am able to call my api via REST Console (chrome addin) but when I call with a ajax request I get a 405 error.

Request Method:OPTIONS
Status Code:200 OK

I do not have any [Authentication] on my methods - yet.

I have looked at this question and have implemented it as shown above.  This related question is NOT a duplicate. servicestack REST API and CORS

The service call (POST) that I am making is...
public object Post(SelectedTroops request)
{
     return new SelectedTroopsResponse { ArrayOfSelectedTroops = request.ArrayOfSelectedTroops };

}
If I am missing anything that may be helpful please let me know.  I guess an side note question may be - how do you effectively trace thru and debug something like this?  Any helpful hints would be more than appreciated.
解决方案
You do have to use:
httpRes.EndRequest();
It's important, it's an extension method in the ServiceStack namespace. I recommend using Tools like ReSharper which makes auto-finding and referencing extension methods trivial.
