Javascript 不同的回应

我正在使用Facebook图形API，使用javascript

fetch

方法请求一些用户数据。问题是，在尝试Graph API Explorer时返回的响应与返回到fetch方法的响应不同

请求是：

在资源管理器中，响应返回所有请求的数据，而在获取方法中，生日、位置和家乡丢失。那么，这些反应差异背后的原因是什么

以下是图形API响应：

{
   "id": "10152311252041311",
   "birthday": "12/11/1992",
   "age_range": {
      "min": 21
   },
   "gender": "male",
   "first_name": "Karim",
   "last_name": "Elbawab",
   "location": {
      "location": {
         "city": "Cairo",
         "country": "Egypt",
         "latitude": 30.0581,
         "longitude": 31.2289
      },
      "id": "115351105145884"
   },
   "cover": {
      "id": "10153054290206311",
      "offset_y": 36,
      "source": "https://scontent.xx.fbcdn.net/v/t31.0-8/s720x720/11080657_10153054290206311_8236239774331416126_o.jpg?oh=7a5e55ce637ddbcbdacb485c5830bbaf&oe=5998BAC0"
   },
   "picture": {
      "data": {
         "height": 958,
         "is_silhouette": false,
         "url": "https://scontent.xx.fbcdn.net/v/t1.0-1/c1.0.958.958/14492344_10154345907211311_2194946159496032335_n.jpg?oh=27591ffb185acde25518df742f7cbf68&oe=598BA899",
         "width": 958
      }
   },
   "hometown": {
      "location": {
         "city": "Port Said",
         "country": "Egypt",
         "latitude": 31.2667,
         "longitude": 32.3
      },
      "id": "106225446079687"
   }
}

下面是我执行提取请求的方式：

var url = "https://graph.facebook.com/v2.8/me?fields=birthday%2Cemail%2Cage_range%2Cabout%2Cgender%2Cfirst_name%2Clast_name%2Clocation%7Blocation%7D%2Ccover%2Cpicture.height(800).width(800)%2Chometown%7Blocation%7D&";
    url += "access_token=" + accessToken.value;

    fetch(url,{
        method:"GET"
    }).then(function(result){
        var user_info = JSON.parse(result._bodyInit);
        authentication_api.loginWithFacebook(user_info).then(function(res) {
            callback(res);
        });
    }).catch(function(error){
        console.log("Error: " + error);
        callback(error);
    });
}

获取响应：

您应该使用来编辑/更新您的问题，以包括您用于发出获取请求的代码。我已经这样做了，我在请求中列出了所有请求的字段，但如图所示，一些请求的字段丢失了。您的访问令牌可能不包括检索这些字段所需的权限。是，我发现原因是访问令牌，因为我硬编码了从Graph API Explorer获得的令牌，它工作正常，但为什么在测试中使用相同的帐户时权限不同
