Question

我正在使用谷歌驱动器API。当我尝试使用

从驱动器中获取文件时

return sequelize.transaction({
  isolationLevel: Sequelize.Transaction.SERIALIZABLE
}, function (t) {

 // your transactions

}).then(function(result) {
  // transaction has been committed. Do something after the commit if required.
}).catch(function(err) {
  // do something with the err.
});

我收到错误

＆＃34;操作无法“完成。（许可不足）。

任何人都知道我需要在仪表板中设置哪个权限？

Answer 1

如果用户需要访问非公开文件，请务必使用Google登录。或者您对用户相关文件列表感兴趣。

要执行此操作，请先请求登录。确保同时设置Google登录的UIDelegate，以便在正确的时间点显示登录屏幕：GIDSignInUIDelegate。要展示它，您可以致电：

GIDSignIn.sharedInstance().signIn()

如果用户已经登录，您可以致电：

if userSignedInBefore {
    GIDSignIn.sharedInstance().signInSilently()
}

假设您在这样的特定类中调用了您的请求（用于说明这个想法）：

class Requester {
    static let service = GTLServiceDrive()

    static func fetchData() {
        let query = GTLQueryDrive.queryForFilesList()
        query?.pageSize = 1
        query?.fields = “files”
        service.executeQuery(query!, delegate: self, didFinish: #selector(self.displayResult(ticket:finishedWithObject:error:)))
    }
    ...
}

此外，您需要GIDSignInDelegate的代表，当用户登录时，这个代表会注意并存储用户的相关信息：

// https://developers.google.com/identity/sign-in/ios/
func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!, withError error: Error!) {
    // Perform any operations when the user disconnects from app here.
    // ...
    if (error == nil) {
        // Perform any operations on signed in user here.
        //            let userId = user.userID                  // For client-side use only!
        //            let idToken = user.authentication.idToken // Safe to send to the server
        // ....
        // Here you will receive an authorizer instance that implements the GTMFetcherAuthorizationProtocol protocol.
        // This authorizer instance will be required by your GTLRDriveService services as authorizer reference.
        // https://developers.google.com/identity/sign-in/ios/api/interface_g_i_d_authentication
        var authorizer = user.authentication.fetcherAuthorizer()

        // Here you can trigger any callback to now fetch the desired data
        Requester.service.authorizer = authorizer
        Requester.fetchData()
    } else {
        print("\(error.localizedDescription)")
    }
}
