Java SDK QuickBooks Online。直接 HTTP — 好的，SDK — 身份验证失败

Question

Java 项目 (Eclipse)。沙盒测试应用。我使用示例 OAuth 应用程序获得了所有必要的令牌和秘密对，并将它们分配给字符串变量：consumerKey、consumerSecret、accessToken、accessTokenSecret、appToken、companyID。

接下来。我尝试通过两种不同的方式授权 QBO：直接使用 HTTP 连接（删除 try/catch 块）：

OAuthConsumer ouathconsumer = new DefaultOAuthConsumer(consumerKey,consumerSecret);

ouathconsumer.setTokenWithSecret(accessToken, accessTokenSecret);

HttpURLConnection urlConnection = null;

URL url = new URL("https://sandbox-quickbooks.api.intuit.com/v3/company/" + companyID + "/customer/4");

urlConnection = (HttpURLConnection)url.openConnection();

urlConnection.setRequestMethod("GET");

urlConnection.setUseCaches(false);

urlConnection.setDoInput(true);

urlConnection.setDoOutput(true);

urlConnection.setRequestProperty("Connection", "Close");

urlConnection.setRequestProperty("Content-Type", "application/json");

urlConnection.setRequestProperty("Accept", "application/json");

ouathconsumer.sign(urlConnection);

urlConnection.connect();

BufferedReader rd = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));

System.out.println(rd.readLine());

rd.close();

而且效果很好！但我想做 SDK 调用。以下来源给了我错误（删除了 try/catch，秘密字符串相同）：

IAuthorizer authorizer = new OAuthAuthorizer(consumerKey, consumerSecret, accessToken, accessTokenSecret);

Context context = new Context(authorizer, appToken, ServiceType.QBO, companyID);

DataService service = new DataService(context);

Customer customer=new Customer();

customer.setId("3");

Customer resultCustomer = service.findById(customer);

最后一行给出当前错误（一些字符串被星号替换）：

com.intuit.ipp.exception.AuthenticationException: ERROR CODE:3200, ERROR MESSAGE:message=ApplicationAuthenticationFailed; errorCode=003200; statusCode=401, ERROR DETAIL:SignatureBaseString: GET&https%3A%2F%2Fsandbox-quickbooks.api.intuit.com%2Fv3%2Fcompany%***%2Fcustomer%2F3&minorversion%3D3%26oauth_consumer_key%***%26oauth_nonce%3D-4488452729022111661%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1450088662%26oauth_token%***%26oauth_version%3D1.0%26requestid%3Dc5bba96ea6894dc3be93588324778891

它说明了身份验证错误，但令牌没问题。请帮帮我。我做错了什么？

Answer 1

已修复。配置中的 URL 结尾不能有斜线！

也可以使用 SDK & log4j 提供的日志工具
