您好，我正在尝试从 AngularJS 向 ServiceStack 发送 PATCH 请求，收到此错误：

Access-Control-Allow-Methods 不允许方法 PATCH。

这是请求标头：

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: */*
Referer: https://pankajb1.dev.ma.net/ui/static/index.html
Accept-Encoding: gzip, deflate, sdch
Accept-Language: en-GB,en-US;q=0.8,en;q=0.6

这是回复：

HTTP/1.1 200 OK

【问题讨论】：

似乎服务器不允许 PATCH 请求，您可以在 Access-Control-Allow-Methods 中看到。

标签： c# asp.net angularjs

【解决方案1】：

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

同时您可以在注册CorsFeature时指定哪些方法可用于CORS，例如：

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