webapi 跨域问题

参考:http://www.cnblogs.com/chenxizhang/p/3821703.html

给自己做个笔记

 HttpContext.Current.Response.AddHeader("Access-Control-Allow-Credentials", "true");
 HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "origin,x-requested-with,content-type");
 HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "POST,GET,OPTIONS");
 HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");

在web.config中添加这段代码

<system.webServer>
<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>
<handlers>
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<remove name="OPTIONSVerbHandler" />
<remove name="TRACEVerbHandler" />
<add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>
</system.webServer>
