我正在尝试设置一项网络服务来查询Google Play购买.我们会为客户存储订单信息,此服务会调用Google Play API来查询订阅详情.

每次我尝试查询购买时,它都会给我错误:

HTTP/1.1 400 Bad Request
{  
   "error":{  
      "errors":[  
         {  
            "domain":"global",
            "reason":"invalid",
            "message":"Invalid Value"
         }
      ],
      "code":400,
      "message":"Invalid Value"
   }
}

这是我尝试过的:

• 在https://console.developers.google.com中创建了一个项目,启用了"Google Play Android Developer API"
• 为类型Web应用程序创建了oAuth 2.0 client_id和client_secret
• 以帐户所有者身份登录后,我生成了一个refresh_token
• 在https://play.google.com/apps/publish中,我转到了设置 - > API访问并将项目链接到我的应用

代码方面,我使用refresh_token来获取access_token:

String refreshToken = "1/ljll6d9ME3Uc13jMrBweqXugV4g4timYcXXXXXXXXX";
HttpPost request = new HttpPost("https://accounts.google.com/o/oauth2/token");
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("client_id", client_id));
params.add(new BasicNameValuePair("client_secret", client_secret));
params.add(new BasicNameValuePair("refresh_token", refreshToken));
params.add(new BasicNameValuePair("grant_type", "refresh_token"));
request.setEntity(new UrlEncodedFormEntity(params));

HttpResponse response = httpClient.execute(request);
HttpEntity entity = response.getEntity();
