【问题描述】：

应用程序在生产服务器上运行，通过代理服务器访问https://www.googleapi.com。那么如何将url而不是https://www.googleapi.com设置为http://www.googleapi.com:443。

目前使用的示例代码是

    File dataStoreDir = new File(resourceDir, credentials);

    JsonFactory jacksonFactory = JacksonFactory.getDefaultInstance();

    //List<String> scopes = Arrays.asList(DriveScopes.DRIVE);
    List<String> scopes = Arrays.asList("http://www.googleapis.com/auth/drive:443");

    HttpTransport httpTransport = GoogleNetHttpTransport.newTrustedTransport();

    FileDataStoreFactory dataStoreFactory = new FileDataStoreFactory(dataStoreDir);


    String clientSecret = config.getClientSecret();

    InputStream in = new FileInputStream(new File(resourceDir, clientSecret));
    GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(jacksonFactory, new InputStreamReader(in));


    // Build flow and trigger user authorization request.
    GoogleAuthorizationCodeFlow flow =
            new GoogleAuthorizationCodeFlow.Builder(
                    httpTransport, jacksonFactory, clientSecrets, scopes)
                    .setDataStoreFactory(dataStoreFactory)
                    .setAccessType("offline")
                    .setAuthorizationServerEncodedUrl("http://www.googleapis.com/auth/drive:443")
                    .build();
    Credential credential = new AuthorizationCodeInstalledApp(
            flow, new LocalServerReceiver()).authorize("user");

    logger.info("Credentials saved to " + dataStoreDir.getAbsolutePath());


    drive =  new Drive.Builder(
            httpTransport, jacksonFactory, credential)
            .setApplicationName(applicationName)
            .build();

如何更改上述代码中的网址？当我更改drive 实例创建时

drive =  new Drive.Builder(
                httpTransport, jacksonFactory, credential)
                .setApplicationName(applicationName).setRootUrl("http://www.googleapis.com:443/")
                .build();

然后它给出错误

【解决方案1】：

Google Drive 可以通过代理服务器工作，方法是将所需的连接应用到Google Drive firewall and proxy setting 中列出的以下主机和端口。

但是，请注意，Google 目前不支持对其地址的连接进行身份验证。您必须绕过 Google Apps 管理员帮助页面中给定地址的身份验证，才能允许 Google 通过您的代理工作。

How to configure your proxy server to work with Google Drive 中给出了可能的代理服务器配置。
