如何使用Dropbox Java/Android SDK v2自動進行身份驗證？

Question

爲了提高應用程序質量，我正在測試：單元測試和UI測試。因爲我在應用程序中使用Dropbox支持，所以我想測試它，並且我需要在測試前驗證Dropbox帳戶（在我的Android應用程序中，用戶可以保存文件，讀取它們，重命名等 - 基本文件例程）。

的Dropbox提供Java/Android SDK v2用的例子，但即使command-line tool需要一些手動操作 - 打開的瀏覽器應用程序的URL，並選擇帳戶：

// Run through Dropbox API authorization process 
     DbxRequestConfig requestConfig = new DbxRequestConfig("examples-authorize"); 
     DbxWebAuth webAuth = new DbxWebAuth(requestConfig, appInfo); 
     DbxWebAuth.Request webAuthRequest = DbxWebAuth.newRequestBuilder() 
      .withNoRedirect() 
      .build(); 

     String authorizeUrl = webAuth.authorize(webAuthRequest); 
     System.out.println("1. Go to " + authorizeUrl); 
     System.out.println("2. Click \"Allow\" (you might have to log in first)."); 
     System.out.println("3. Copy the authorization code."); 
     System.out.print("Enter the authorization code here: "); 

     String code = new BufferedReader(new InputStreamReader(System.in)).readLine(); 
     if (code == null) { 
      System.exit(1); return; 
     } 
     code = code.trim(); 

     DbxAuthFinish authFinish; 
     try { 
      authFinish = webAuth.finishFromCode(code); 
     } catch (DbxException ex) { 
      System.err.println("Error in DbxWebAuth.authorize: " + ex.getMessage()); 
      System.exit(1); return; 
     } 

     System.out.println("Authorization complete."); 
     System.out.println("- User ID: " + authFinish.getUserId()); 
     System.out.println("- Access Token: " + authFinish.getAccessToken()); 

任何可能性使Dropbox的身份驗證自動無需進行人工干預？我期望提供應用密鑰/祕密，帳戶電子郵件/密碼，並獲得會話accessToken。

PS。我想避免使用Robelectric + Espresso並將其保留在單元/集成測試中，而不是在UI測試中。

這是我的測試模板（我希望它有助於某人）。 您必須執行TODO並至少手動運行測試兩次（以粘貼授權碼和訪問令牌），然後您可以執行測試。所有下一個測試調用都不需要手動執行任何操作。

public class DropboxFileSystemTest { 

    // credentials 
    private static final String APP_KEY = ""; // TODO : paste your app key 
    private static final String APP_SECRET = ""; // TODO : paste your app secret 

    // do run the test and follow the instructions 
    private static final String accountEmail = "test@domain.com"; // TODO : paste your test Dropbox account 
    private static String authCode; // TODO : run the test and paste auth code 
    private static String accessToken // TODO : run the test and paste access 

    private DbxAppInfo appInfo = new DbxAppInfo(APP_KEY, APP_SECRET); 

    // Run through Dropbox API authorization process 
    private DbxRequestConfig requestConfig = new DbxRequestConfig(DropboxFileSystemTest.class.getSimpleName()); 
    private DbxWebAuth webAuth = new DbxWebAuth(requestConfig, appInfo); 

    private void startAuth() throws IOException { 
     DbxWebAuth.Request webAuthRequest = DbxWebAuth.newRequestBuilder() 
      .withNoRedirect() 
      .build(); 

     String authorizeUrl = webAuth.authorize(webAuthRequest); 
     System.out.println("1. Go to " + authorizeUrl); 
     System.out.println("2. Click \"Allow\" (you might have to log in first). WARNING: log-in to " + accountEmail); 
     System.out.println("3. Copy the authorization code."); 
     System.out.println("4. Paste the authorization code to this test `this.authCode` value"); 
     System.out.println("5. Re-run the test"); 
    } 

    private DbxClientV2 client; // to be used for the requests 

    private void initWithAccessToken() { 
     DbxRequestConfig config = new DbxRequestConfig(UUID.randomUUID().toString()); 
     client = new DbxClientV2(config, accessToken); 
    } 

    private void initAndVerifyAccount() throws DbxException { 
     initWithAccessToken(); 

     // check expected account (trying to prevent user account to be wiped out) 
     DbxClientV2 client = DbxClientHolder.get().getClient(); 
     FullAccount account = client.users().getCurrentAccount(); 
     if (!account.getEmail().equals(accountEmail)) 
      throw new RuntimeException("Wrong account: current is " + account.getEmail() + ", but " + accountEmail + " is expected"); 
    } 

    private void clearFileSystem() throws FileSystemException { 
     // TODO : clear Dropbox file system 
    } 

    @Before 
    public void setUp() throws IOException, FileSystemException, DbxException { 
     auth(); 
     clearFileSystem(); 
    } 

    private void finishAuth() { 
     DbxAuthFinish authFinish; 
     try { 
      authFinish = webAuth.finishFromCode(authCode); 
     } catch (DbxException ex) { 
      System.err.println("Error in DbxWebAuth.authorize: " + ex.getMessage()); 
      System.exit(1); return; 
     } 

     System.out.println("Authorization complete."); 
     System.out.println("- User ID: " + authFinish.getUserId()); 
     System.out.println("- Access Token: " + authFinish.getAccessToken()); 
     System.out.println(); 

     System.out.println("1. Copy the access token"); 
     System.out.println("2. Paste the access token to this test `this.accessToken` value"); 
     System.out.println("3. Re-run the test"); 

     accessToken = authFinish.getAccessToken(); 
    } 

    private void auth() throws IOException, FileSystemException, DbxException { 
     if (accessToken == null) { 
      if (authCode != null) { 
       finishAuth(); 
       throw new RuntimeException("Manual actions required: copy-paste access token"); 
      } else { 
       startAuth(); 
       throw new RuntimeException("Manual actions required: copy-paste authCode"); 
      } 
     } else { 
      initAndVerifyAccount(); 
     } 
    } 

    @After 
    public void tearDown() throws FileSystemException { 
     if (client != null) { 
      clearFileSystem(); 
     } 
    } 

    @Test 
    public void testSmth() { 
     // TODO : write your test using `this.client` for requests 
    }

不，Dropbox API不提供自動執行應用程序授權流程的方法。

請注意，您可以存儲並重新使用訪問令牌，因此您可能只需手動爲測試帳戶獲取一個，然後重新使用它。
