跨域405(Method Not Allowed)问题
zepot post没有问题,用plupload上传出现了这个错误,options过不去。显示Response for preflight has invalid http status code 405
在global中处理下option
protected void Application_BeginRequest() { if (Request.Headers.AllKeys.Contains("Origin") && Request.HttpMethod == "OPTIONS") { Response.End(); } }
另外,还要注意header的设定。多个允许的自定义header逗号隔开。不然也会被拒绝。
<httpProtocol> <customHeaders> <add name="Access-Control-Allow-Origin" value="*" /> <add name="Access-Control-Allow-Headers" value="Content-Type,Token" /> <add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS" /> </customHeaders> </httpProtocol>
正文到此结束
