请求的资源不支持http方法'OPTIONS' [英] The requested resource does not support http method 'OPTIONS'

问题描述

大家好，

当我通过POSTMAN发送请求时，它工作正常，但当我发送请求时，我的Web应用程序（用于POST，DELETE和PUT，PATCH）动词），系统给我错误  请求的资源不支持
< g class =" gr_ gr_189 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace"数据-GR-ID =" 189" id =" 189"> http < / g> 方法'选项' 

我花费数小时根据我删除的一些网站并添加属性到web配置，但我没有得到任何正确的答案。在此我添加了配置文件。我做错了吗？< g class =" gr_ gr_611 gr-alert gr_gramm gr_inline_cards gr_run_anim
Punctuation multiReplace"数据-GR-ID =" 611" id =" 611"> thing。< / g>

我正在使用WEB API 2

解决方案

我认为你已经有了解决方案，如果没有，你可以在控制器文件中包含下一个代码：

 public HttpResponseMessage Options（）
 {
 return new HttpResponseMessage {StatusCode = HttpStatusCode.OK}; 
} 
 

问候。

Hi All,

When I send the request via POSTMAN it works fine, but When I send the request my web application ( for the POST, DELETE and PUT, PATCH verbs ), system gives me error The requested resource does not support <g class="gr_ gr_189 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" data-gr-id="189" id="189">http</g> method 'OPTIONS' 

I spend hours and hours, according to some websites I removed and added attributes to web config, but I didn't get any proper answer. Herewith I added my config file. Am I doing any wrong <g class="gr_ gr_611 gr-alert gr_gramm gr_inline_cards gr_run_anim Punctuation multiReplace" data-gr-id="611" id="611">thing.</g>

I am using WEB API 2

Hi,

I think you have got already the solution, if not you could include next code in controller file:

   public HttpResponseMessage Options()
   {
      return new HttpResponseMessage { StatusCode = HttpStatusCode.OK };
   }

Regards.
