我的个人地带在 web.config 中添加 (全局)
<system.webServer> <httpProtocol> <customHeaders> <add name="Access-Control-Allow-Methods" value="OPTIONS,POST,GET"/> <add name="Access-Control-Allow-Headers" value="x-requested-with"/> <add name="Access-Control-Allow-Origin" value="*" /> </customHeaders> </httpProtocol> </system.webServer>
设置单个一般处理程序可以跨域
context.Response.ClearHeaders();
context.Response.AppendHeader("Access-Control-Allow-Origin","");
string requestHeaders = context.Request.Headers["Access-Control-Request-Headers"];
context.Response.AppendHeader("Access-Control-Allow-Headers",
string.IsNullOrEmpty(requestHeaders) ? "" : requestHeaders);
context.Response.AppendHeader("Access-Control-Allow-Methods", "POST, OPTIONS");
