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

为了提高应用程序质量，我正在进行测试：单元测试和UI测试。由于我在应用程序中有Dropbox支持，我想测试它，在我的android应用程序中测试之前，我需要对Dropbox帐户进行身份验证，用户可以保存文件、读取文件、重命名文件等-基本的文件例程

Dropbox提供了一些示例，但甚至需要一些手动操作-使用URL打开浏览器应用程序并选择帐户：

// 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());

是否有可能在无需手动交互的情况下自动进行Dropbox验证？我希望为会话提供应用程序密钥/密码、帐户电子邮件/密码和accessToken

另外，我希望避免使用Robeelectric+Espresso，并将其保留在单元/集成测试中，而不是UI测试中。

不，Dropbox API不提供自动化应用程序授权流程的方法

请注意，您可以存储和重用访问令牌，因此您可能只需要手动为您的测试帐户获取一次访问令牌，然后再重新使用它。

这是我的测试模板，我希望它能帮助某些人。 您必须执行TODO并手动运行测试至少两次，以粘贴身份验证代码和访问令牌，然后才能执行测试。接下来的所有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
    }

访问令牌是否与应用程序包相关？我想知道为我的生产应用程序接收的访问令牌是否会被接受为unit testA Dropbox API访问令牌只标识应用程序用户对。它不绑定到特定的Java/Android包，因此您可以从多个位置/环境使用相同的访问令牌。
