如何以编程方式向Google进行身份验证？现在的ClientLogin(https://developers.google.com/accounts/docs/AuthForInstalledApps)已过时,我们如何能够执行编程认证,以与谷歌的OAuth2？

使用ClientLogin,我们可以 使用电子邮件和密码参数向https://www.google.com/accounts/ClientLogin发送帖子, 并获取身份验证令牌.

使用OAuth2我找不到解决方案!

我的应用程序是一个java后台进程.我看到,点击此链接:developers.google.com/accounts/docs/OAuth2InstalledApp#refresh,如何使用刷新的令牌获取新的访问令牌.

问题是,当我有一个新的有效访问令牌时,我找不到一个关于如何实例化Analytics对象(例如)来执行查询的java示例

这是我的代码在调用"execute()"时返回401无效凭据:

public class Test {

static final String client_id = "MY_CLIENT_ID";
static final String client_secret = "MY_SECRET";
static final String appName = "MY_APP";

private static final HttpTransport HTTP_TRANSPORT = new NetHttpTransport();
private static final JsonFactory JSON_FACTORY = new JacksonFactory();

static String access_token = "xxxx";
static String refreshToken = "yyyyy";

public static void main (String args[]){

    try {

        GoogleCredential credential = 
            new GoogleCredential.Builder()
                .setTransport(HTTP_TRANSPORT)
                .setJsonFactory(JSON_FACTORY)
                .setClientSecrets(client_id, client_secret).build();
        credential.setAccessToken(access_token);
        credential.setRefreshToken(refreshToken); …
