arcserver 跨域问题

跨域问题：
XMLHttpRequest cannot load http://10.19.1.59/ArcGIS/rest/services/mapWGS/MapServer/?f=json. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.

在服务器端 C:\Inetpub\wwwroot\ArcGIS\rest\Web.Config 和 C:\Inetpub\wwwroot\ArcGIS\Services\Web.Config 中添加以下段落
<system.webServer>
    <httpProtocol>
      <customHeaders>
        <add name="Access-Control-Allow-Origin" value="*"/>
      </customHeaders>
    </httpProtocol>
</system.WebServer>

IIS下ArcGIS右键'属性'，'HTTP头'在'自定义HTTP头'中添加头名'Access-Control-Allow-Origin'，值'*'
