AngularJS修补法补丁没有被访问控制允许的方法

Question

嗨，我试图发送PATCH要求允许从AngularJS到ServiceStack，收到此错误：

Method PATCH is not allowed by Access-Control-Allow-Methods.

这是请求头：

Connection: keep-alive 
Pragma: no-cache 
Cache-Control: no-cache 
Access-Control-Request-Method: PATCH 
Origin: 
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.85 Safari/537.36 
Access-Control-Request-Headers: accept, content-type

Accept-Encoding: gzip, deflate, sdch 
Accept-Language: en-GB,en-US;q=0.8,en;q=0.6 

这是响应：

Answer 1

的CorsFeature默认情况下不允许PATCH（它是will in next v4.0.48 release）。

你可以指定哪些方法应该可用于CORS同时注册CorsFeature时，如：

Plugins.Add(new CorsFeature(
    allowedMethods: "GET, POST, PUT, DELETE, PATCH, OPTIONS"));
