我试图使CORS请求正常工作。使用以下JS代码，我得到此错误：XMLHttpRequest cannot load http://localhost:65491/?token=u80h9kil9kjuu02539buak4r6n&user=~me. No 'Access- Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1:50303' is therefore not allowed access.

这是JS代码：

$.ajax({
     url: "http://localhost:60906/",
     data: {token : 'u80h9kil9kjuu02539buak4r6n', user : '~me'},
     type: "GET",
     crossDomain: true,
     success: function( response ) {
         alert('Success!' + response);
         var context = response;
        }
  });

当我使用chrome的devtools查看网络时，我发现'Access-Control-Allow- Origin'确实没有标题。但是，当我手动加载该网站时，它就存在了！

我使用以下代码设置标题：

response = JsonResponse(simpleWeek)
response['Access-Control-Allow-Origin'] = '*'
return response

希望能有所帮助！
