如何将google api访问令牌从java服务器传递到gapi javascript客户端？

1 年，8 月 Questions & Answers 943

我能够使用运行在Tomcat中的Java AuthorizationCodeFlow获取凭据

现在，我正试图将我在服务器上获得的访问令牌传递回客户机，以便我们能够使用gapi javascript客户机在浏览器中执行工作，而无需通过服务器

我使用以下方法在gapi中设置访问令牌：

function setAccessToken() {
    gapi.auth.setToken({
        access_token: '<access_token from server>'
    });
}

然后我给gapi打电话。客户加载以获取驱动器客户端代码：

gapi.client.load('drive', 'v2', onDriveClientLoaded);

然后我调用一个函数来获取或创建GoogleDrive中的文件夹（这已经使用gapi.auth.authorize（）进行了测试，因此我知道代码应该可以正常工作）

function onDriveClientLoaded() {
    getOrCreateFolder();
}

但在getOrCreateFolder中，当我调用gapi时。客户驾驶儿童列表（…）答案是

{
    code: 401,
    message: "Invalid Credentials",
    ...
}

我见过很多地方有人表示他们这样做过。但到目前为止，我还不能让它工作

在fiddler中，我得到了以下回应：

   }
  ],
  "code": 401,

 }
}

事实证明，一切都按预期进行。我需要查看令牌的刷新，因为我使用的access_令牌无效，因此出现了“Invalid Credentials”消息

我通过在postman中放置以下内容来测试access_令牌：
```
https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=<access_token>
```
当使用不正确的访问令牌时，我得到了无效凭据响应，但当我刷新令牌时，我得到了以下有效响应：
```
{
 "issued_to": "<some_id>.apps.googleusercontent.com",
 "audience": "<some_id>.apps.googleusercontent.com",
 "scope": "https://www.googleapis.com/auth/drive",
 "expires_in": 3470,
 "access_type": "offline"
}
```
