Question

我在执行 gdata api 示例代码时遇到错误。我是 api 的新手。请让我知道相同的解决方案。我需要在哪里放置验证码以及如何放置验证码。

这正是它所说的 - 该服务要求用户解决验证码，然后您才能再次使用自动登录。

异常(exception)应包含相关验证码的 URL。来自client login用户指南:

A failure response from ClientLogin contains an error code and a URL to an error page that can be displayed to the user. If the error code is a CAPTCHA challenge, the response also includes a URL to a CAPTCHA image and a special token. Your application should be able to solicit an answer from the user and then retry the login request.

URL 可通过 getCaptchaUrl() 获得方法。
