Question

过去一小时我一直在阅读有关XMLHttpRequest的内容，但我似乎可以让这项工作成功。所以，我有一个django服务器与tastypie和另一个服务器/端口上的JavaScript客户端，当我尝试做一个jquery帖子我得到一个

XMLHttpRequest cannot load http://127.0.0.1:8000/api/smart/rating/. Origin http://localhost is not allowed by Access-Control-Allow-Origin.

我在客户端

上收到Xmlthhprequest错误消息

Django代码：

class RatingResource(ModelResource):
city = fields.ForeignKey(CityResource, 'city')
user = fields.ForeignKey(UserResource, 'user')
class Meta:
    queryset = Rating.objects.all()
    resource_name = 'rating'
    #authentication = BasicAuthentication()
    #authorization = DjangoAuthorization()

我的jquery呼叫从localhost发布：80到localhost：8000：

$('#star').raty({
  path: "../assets/img/",
  score    : rating,
  click : function(score, evt) {
      window.rate_app = score;
      var url = "http://127.0.0.1:8000/api/smart/rating/";
      //var comment = $('#textarea').val();
      var comment = "teste do php";
      console.log(cityId);  
      $.post(url,{city : '/api/smart/city/'+cityId+'/' ,comment : comment,id:'4',resource_uri:'/api/smart/rating/4/',rating : score, user: '/api/smart/auth/user/2/'},function(data,status){
          if (data=="error")
              console.log("error");
          else
              console.log("success");
      });

  }
});

更新：

HTTP / 1.0 401 UNAUTHORIZED

curl --dump-header - -H "Content-Type: application/json" -X POST --data '{"city": "/api/smart/city/35/", "comment": "teste do php", "id": "4", "resource_uri": "/api/smart/rating/4/", "rating": "3","user_id": "/api/smart/auth/user/2/"}' `http://localhost:8000/api/smart/rating/`

我做错了什么？

您好，我认为您实际上是在提出交叉来源请求。

要启动跨源请求，浏览器会使用Origin HTTP标头发送请求。此标头的值是为页面提供服务的站点。

要允许该请求，它会在其响应中发送一个Access-Control-Allow-Origin标头。标题的值表示允许的源站点。

Access-Control-Allow-Origin: localhost:80

基本上你需要允许服务器端的选项请求发送回来 Access-Control-Allow-Origin标头
