适用于iOS的Google Sheet API的身份验证范围错误 [英] Insufficient authentication scopes error for Google Sheet API for iOS

问题描述

我正在尝试使用适用于iOS的Google Sheets API来获取Google Sheet.我已经成功添加了用户身份验证，因为它不再要求API密钥，但现在出现403错误:

I'm trying to fetch a Google Sheet with the Google Sheets API for iOS. I've successfully added the user authentication since it's no longer asking for an API key, but I'm now getting a 403 error for:

Request had insufficient authentication scopes*.

我在Google Developers Console中添加了以下范围.

I've added the following scopes in the Google Developers Console.

/auth/drive
/auth/spreadsheets

这是我用来执行和执行查询的代码.

And here's the code I'm using to make and execute the query.

let potentialShowSheetID = "1n4wvD2vSSiAnG_pnD9rWR6dNCSnZz0pAGAiSYRaJCKs"
let service = GTLRSheetsService()
private let scopes = [kGTLRAuthScopeSheetsSpreadsheets]  // This was specified in 
    // another Stack Overflow question, but I'm not sure how it would be used
    // and it doesn't seem to help.

override func viewDidLoad() {
    super.viewDidLoad()

    service.authorizer = GIDSignIn.sharedInstance().currentUser.authentication.fetcherAuthorizer()

    let query = GTLRSheetsQuery_SpreadsheetsGet.query(withSpreadsheetId: potentialShowSheetID)

    service.executeQuery(query) { (ticket, data, error) in
        print("GTLRService ticket: \(ticket)")
        if error != nil {
            print("GTLRService potential show query error: \(error!)")
        }
        else {
            print("data: \(data ?? "unknown data")")

        }
    }
}

是否可以使用iOS版Google Sheets API在查询中指定范围?我对框架进行了很好的浏览，似乎从来没有将其作为参数.也许我想念其他东西.

Is there a way to specify the scope in the query with the Google Sheets API for iOS? I looked through the framework pretty well and it doesn't ever seem to take that as a parameter. Maybe I'm missing something else.

更新:我检查了用户的授予范围，它不包括Drive或Sheets API.

UPDATE: I checked the granted scopes for the user and it doesn't include the Drive or Sheets API.

print("Scopes:", GIDSignIn.sharedInstance()?.currentUser.grantedScopes ?? "unknown scopes")

    // Prints -> Scopes: [https://www.googleapis.com/auth/userinfo.profile, https://www.googleapis.com/auth/userinfo.email]

如何指定身份验证期间要授予访问权限的范围?

How can I specify the scopes to grant access to during authentication?

推荐答案

在对Google Sign In API标头进行了一些挖掘之后，我发现只需要为此指定范围:

After some digging around the Google Sign In API headers, I found I just had to specify the scopes with this:

GIDSignIn.sharedInstance()?.scopes = [kGTLRAuthScopeSheetsSpreadsheets, kGTLRAuthScopeCalendar]

...使用 GIDSignInButton 登录之前.

...before signing in with GIDSignInButton.
