关于 webapi ajax进度条信息设置
1、Web.config 设置跨域
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />
<add name="Access-Control-Allow-Headers" value="Content-Type" />
<add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE,OPTIONS" />
</customHeaders>
</httpProtocol>2、Global.asax中配置OPTIONS
protected void Application_BeginRequest()
{
if (Request.Headers.AllKeys.Contains("Origin") && Request.HttpMethod == "OPTIONS")
{
Response.Flush();
}
}
