ios - 连接到 Google Drive API 时出错(Swift 5)

Question

我想在我的应用程序中连接到 Google Drive API，以便显示用户文件列表并能够将它们下载到设备。我正在关注这个样本 Integrate Google Drive to iOS app

我连接了 Google SDK 并成功授权了用户。但是我无法以任何方式获取其文件列表。我不断收到以下错误:

"Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup."

我多次在 Google 控制台中检查我的应用程序和设置，一步步完成，但仍然无法解决这个问题。有没有人遇到过同样的问题？

我的代码和截图:

//class AppDelegate...
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        GIDSignIn.sharedInstance().clientID = "Me client ID"
        return true
}

//class myVC: GIDSignInDelegate...
override func viewDidLoad() {
        super.viewDidLoad() 
        GIDSignIn.sharedInstance().presentingViewController = self
        GIDSignIn.sharedInstance().delegate = self
        GIDSignIn.sharedInstance().scopes = [kGTLRAuthScopeDrive]
        GIDSignIn.sharedInstance().restorePreviousSignIn()
}

func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!,
              withError error: Error!) {
        if let error = error {
            print("Google autorization error: \(error.localizedDescription)")
            return
        }
        guard let token = user.authentication.accessToken else { return }
    SourceAuthorizationStateManager.shared.addAuthorizedSource(.googleDrive)
    
    let fullName = user.profile.name
    print("Google authorization successful. User name: \(fullName ?? "Error: no user name")\nUser token: \(token)")
}

//class GoogleDriveFileListSource...
private var fileListTicket: GTLRServiceTicket?
var files: [FileModelProtocol] {
        guard let files = fileList?.files else { return [] }
        return files.map { GoogleDriveFileModel($0) }
}

lazy var driveService: GTLRDriveService = {
    let service = GTLRDriveService()
    service.shouldFetchNextPages = true
    service.isRetryEnabled = true
    return service
}()

func fetchFileList(path: String?, _ completion: @escaping () -> Void) {
        let query = GTLRDriveQuery_FilesList.query()
        query.fields = "kind,nextPageToken,files(mimeType,id,kind,name,webViewLink,thumbnailLink,trashed)"
        
        fileListTicket = driveService.executeQuery(query,
                                                   completionHandler: { [weak self] (_, resultObject, error) in
                                                    if let error = error {
                                                        debugPrint("driveService.executeQuery error: \(error.localizedDescription)")
                                                        return
                                                    }
                                                    
                                                    guard let self = self,
                                                        let fileList = resultObject as? GTLRDrive_FileList else { return }
                                                    
                                                    self.fileList = fileList
                                                    self.fileListTicket = nil
                                                    
                                                    completion()
     })
}

已解决。感谢所有提供帮助的人。我所要做的就是将用户身份验证状态传输到 driveService 并将 GTMSessionFetcher 导入到我的文件中。

var googleUser: GIDGoogleUser?
class myVC: GIDSignInDelegate {
...
func sign(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!,
              withError error: Error!) {
        if let error = error {
            print("Google autorization error: \(error.localizedDescription)")
            return
        }
        guard let token = user.authentication.accessToken else { return }
    SourceAuthorizationStateManager.shared.addAuthorizedSource(.googleDrive)
    googleUser = user   //Here I have saved the current user

    let fullName = user.profile.name
    print("Google authorization successful. User name: \(fullName ?? "Error: no user name")\nUser token: \(token)")
}
}

class GoogleDriveFileListSource {
...
lazy var driveService: GTLRDriveService = {
    let service = GTLRDriveService()
    if let user = googleUser {
    service.authorizer = user.authentication.fetcherAuthorizer() //Here I passed the status
    }
    service.shouldFetchNextPages = true
    service.isRetryEnabled = true
    return service
}()
}

现在代码看起来不太好，我会考虑如何改进它。但这已经有效了，我得到了用户文件的列表。
