无法获取JSON数据

-1

好的，所以我试图从这个URL获取一些JSON数据;无法获取JSON数据

https://maps.googleapis.com/maps/api/place/details/json?placeid=ChIJcUQQbsYJGToRnGdYmvWmmRs&key=API_KEY

但对于许多标签，在logcat的是说 '没有价值'。如果您在浏览器中看到JSON响应，那些数据清晰可见。

代码片段：

public void asd(String id){ 
    StringRequest sr = new StringRequest(Request.Method.GET, id, new Response.Listener<String>() { 
     @Override 
     public void onResponse(String response) { 
      try { 
       JSONObject obj =new JSONObject(response); 
       Log.i("response",response); 
       obj.get("international_phone_number"); 
      } catch (JSONException e) { 
       e.printStackTrace(); 
      } 
     } 
    }, new Response.ErrorListener() { 
     @Override 
     public void onErrorResponse(VolleyError error) { 
      Log.i("sdsd",error.toString()); 
     } 
    }); 
    requestQueue.add(sr); 
}

的logcat：

您是否使用API_KEY与否？ – Nour

“如果您在浏览器中看到JSON响应”无法做到这一点，那就需要一个API密钥。 – njzk2

'international_phone_number'在你的json对象中没有这样的键。只有键是'html_attributions'和'结果' – njzk2

您的错误指出密钥不在响应的顶层，而不是它不存在于数据中的任何位置。

您必须进入results密钥。

JSONObject obj =new JSONObject(response); 
JSONObject result = response.getJSONObject("results"); 
String inumber = result.getString("international_phone_number");

尝试getJSONObject insted刚刚得到。

像如下：

@Override 
public void onResponse(String response) { 
    try { 
     JSONObject obj =new JSONObject(response); 
     JSONObject results = object.getJSONObject("results"); 
     String internationalNumber = result.getString("international_phone_number"); 
    } catch (JSONException e) { 
     e.printStackTrace(); 
}

}
