Question

我在web.Server元素中配置了Web.Config。

<httpProtocol>
      <customHeaders>
        <add name="Access-Control-Allow-Origin" value="http://localhost:xxxxx" />
        <add name="Access-Control-Allow-Headers" value="content-type" />
        <add name="Access-Control-Allow-Methods" value="GET, POST, OPTIONS, PUT, DELETE" />
      </customHeaders>
</httpProtocol>

来到GET请求检索所有数据。

当我想在请求中POST新元素时，我得不到错误405方法。可能是什么原因？

请求示例：一般：

Request URL:http://localhost:xxxxx/api/company
Request Method:OPTIONS
Status Code:405 Method Not Allowed

响应标题：

Access-Control-Allow-Headers:content-type
Access-Control-Allow-Methods:GET, POST, OPTIONS, PUT, DELETE
Access-Control-Allow-Origin:http://localhost:yyyyy
Allow:GET,POST
Cache-Control:no-cache
Content-Length:76
Content-Type:application/json; charset=utf-8

请求标题：

Accept:*/*
Accept-Encoding:gzip, deflate, br
Accept-Language:pl-PL,pl;q=0.8,en-US;q=0.6,en;q=0.4
Access-Control-Request-Headers:content-type
Access-Control-Request-Method:POST
Connection:keep-alive
Host:localhost:xxxxx
Origin:http://localhost:yyyyy
Referer:http://localhost:yyyyy/ddddd/zzzzzz

Answer 1

我相信Access-Control-Allow-Origin应该是“*”。然后它可能会工作。

ASP.NET MVC中不允许POST方法（使用CORS）
