接口跨域

需要在请求头加配置

响应头添加

Response.AddHeader("Access-Control-Allow-Origin","*");

或者在web.config 配置

<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />
<add name="Access-Control-Allow-Headers" value="*" />
<add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE" />
</customHeaders>
</httpProtocol>

或者在IIS配置

Access-Control-Allow-Origin 的值最好配置相应的请求方域名，要是*会存在安全问题
