如何使用Dropbox Java/Android SDK v2自动进行身份验证？

Question

为了提高应用程序质量，我正在测试：单元测试和UI测试。因为我在应用程序中使用Dropbox支持，所以我想测试它，并且我需要在测试前验证Dropbox帐户（在我的Android应用程序中，用户可以保存文件，读取它们，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需要一些手动操作 - 打开的浏览器应用程序的URL，并选择帐户：

// 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的身份验证自动无需进行人工干预？我期望提供应用密钥/秘密，帐户电子邮件/密码，并获得会话accessToken。

PS。我想避免使用Robelectric + Espresso并将其保留在单元/集成测试中，而不是在UI测试中。

这是我的测试模板（我希望它有助于某人）。 您必须执行TODO并至少手动运行测试两次（以粘贴授权码和访问令牌），然后您可以执行测试。所有下一个测试调用都不需要手动执行任何操作。

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不提供自动执行应用程序授权流程的方法。

请注意，您可以存储并重新使用访问令牌，因此您可能只需手动为测试帐户获取一个，然后重新使用它。
