Question

我试图通过Google Drive API v3检索用户信息。

var request = this.driveService.About.Get();
request.Fields = "user.displayName";

var accountInfo = await request.ExecuteAsync();

即使我用消息指定了它抱怨的字段：

Google.Apis.Requests.RequestError ＆＃39;字段＆＃39;此方法需要参数。 [400]

＆＃39;字段＆＃39;

是否意味着其他内容

Answer 1

我必须使用Oauth2Service而不是DriveService，如下所示：

var request = this.authService.Userinfo.Get();

request.Fields = "email";

var accountInfo = await request.ExecuteAsync();

Answer 2

我不知道它是否仍然有效，但这在过去对我有用：

        'https://www.googleapis.com/drive/v3/about?fields=user',
        {
            method: 'GET',
            headers: {
                Authorization: 'Bearer ' + token,
            }
        },

Answer 3

GoogleCredential credential = new GoogleCredential().setAccessToken(googleDriveAccessToken);
    credential.refreshToken();

apachetransport = GoogleApacheHttpTransport.newTrustedTransport(); 

Drive service = new  Drive.Builder(apachetransport, JSON_FACTORY,credential)
                .setApplicationName(APPLICATION_NAME)
                .build();

Get get = service.about().get();

com.google.api.services.drive.model.About about = get.setFields("user").execute();

User user = about.getUser();

System.out.println(user.getEmailAddress());
