HTTP(二): http首部字段;

比如:

 getUsers: function(params) {
        var req = {
          method: "GET",
          url: commonService.getPlatformServerUrl("users", "page=" + params.page() + "&pageSize=" + params.count()),
          data: {},
          headers: {
            "Range": "Bytes=5000-10000",
            "Form" : "1287282298@qq.com",
            "Host" : "www.baidu.com",
          }
        };
        return $http(req);
      },
