Purchases.products：获取API

Question

我正在尝试获取产品信息，但出了点问题。有人知道到底出了什么问题吗？String query ="https://www.googleapis.com/androidpublisher/v3/applications/jksldf/purchases/products/kmdsd/tokens/kjls"  HttpURLConnection connection;            try {                connection = (HttpURLConnection) new URL(query).openConnection();                connection.setRequestMethod("GET");                connection.setUseCaches(false);                connection.connect();                if (HttpURLConnection.HTTP_OK == connection.getResponseCode()) {                    BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream()));                    String line;                    StringBuilder stringBuilder = new StringBuilder();                    while ((line = bufferedReader.readLine()) != null) {                        stringBuilder.append(line);                        JSONArray ja = new JSONArray(stringBuilder);                    }                }            } catch (Throwable throwable) {                throwable.printStackTrace();            }        }    }

Answer 1

当我将 url 粘贴到浏览器中时，我还会收到一条错误消息：

  "code": 401,  
  "message": "Login Required"

这意味着您将需要一个访问令牌才能使用他们的 API
