在WCF服务上启用CORS。获取HTTP 405：方法不允许 [英] Enable CORS on WCF Service. Get HTTP 405: Method Not Allowed

问题描述

我尝试在WCF服务上启用CORS。当我尝试从我的客户端发送请求时，使用 OPTIONS 动词发送请求。我总是得到一个 HTTP 405：方法不允许错误

如果我尝试使用Fiddler并创建相同的请求 POST 动词的回应似乎是正确的。

我试图移除 webDAV 在教程的帮助下
：

  protected void Application_BeginRequest（object sender，EventArgs e）
 { 
 HttpContext.Current.Response.AddHeader（Access-Control-Allow-Origin，*）; 
 if（HttpContext.Current.Request.HttpMethod ==OPTIONS）
 {
 HttpContext.Current.Response.AddHeader（Cache-Control，no-cache）; 
 HttpContext.Current.Response.AddHeader（Access-Control-Allow-Methods，GET，POST）; 
 HttpContext.Current.Response.AddHeader（Access-Control-Allow-Headers，Content-Type，Accept）; 
 HttpContext.Current.Response.AddHeader（Access-Control-Max-Age，1728000）; 
 HttpContext.Current.Response.End（）; 
} 
} 
  

I am trying to enable CORS on a WCF service. When I try to send a request from my client, the request is sent using the OPTIONS verb. I always get a HTTP 405: Method not allowed error

If I try using Fiddler and create the same request with the POST verb the response seems to be correct.

I have tried to remove webDAV with the help of the tutorial http://brockallen.com/2012/10/18/cors-iis-and-webdav/ but it doesnt seem to work.

I have updated my WCF to enable CORS referring to the tutorial http://enable-cors.org/server_wcf.html. I am not sure what is going wrong. The response seem to have the CORS header

Any help would be highly appreciated.

PS: I did not want to make the question very big and confusing. If you would like to look at my config be let me know and I can share it

Check this link http://praneeth4victory.wordpress.com/2011/09/29/405-method-not-allowed/:

protected void Application_BeginRequest(object sender, EventArgs e)
{
          HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
          if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
{
               HttpContext.Current.Response.AddHeader("Cache-Control", "no-cache");
               HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST");
               HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Content-Type, Accept");
               HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000");
               HttpContext.Current.Response.End();
              }
}
