获取错误{“error”：“invalid_grant”，“error_description”：“令牌已过期或吊销”。}来自Google oauth2 API

Question

2016年，我在我的谷歌开发者控制台账户上创建了一个应用

c.g.api.client.auth.oauth2.Credential    : unable to refresh token

com.google.api.client.auth.oauth2.TokenResponseException: 400 Bad Request

这是因为访问令牌或刷新令牌在2016年后的今天过期了吗？我应该尝试从google开发者控制台重置客户端密码吗？

编辑——下面是我正在使用的代码

public GoogleMailComponent googleMailComponent() {
        GoogleMailConfiguration googleMailConfiguration = new GoogleMailConfiguration();
        googleMailConfiguration.setClientId(clientId);
        googleMailConfiguration.setClientSecret(clientSecret);
        googleMailConfiguration.setAccessToken(accessToken);
        googleMailConfiguration.setRefreshToken(refreshToken);

        GoogleMailComponent googleMailComponent = new GoogleMailComponent();
        googleMailComponent.setConfiguration(googleMailConfiguration);
        return googleMailComponent;
    }

Answer 1

删除tokens/StoredCredential文件可以解决这个问题。

下次当我运行Java应用程序试图连接到Google Sheets时，它提示我

1. 转到一个URL
2. 允许访问Google API
