Google 图书 Oauth 访问令牌授权错误

Question

您好，我一直在开发一个应用程序，让用户可以使用 Google 图书 API 搜索图书。一切正常，直到我想访问用户最喜欢的书，添加和删除它们。错误与授权有关。 google 本书 api 在这里说访问最喜欢的书 as

GET https://www.googleapis.com/books/v1/mylibrary/bookshelves?key=yourAPIKey Authorization: /* auth token here */

我正在做的就是这个。

var userId: String?
    if(UserStats.currentUser?.authentication.idToken != nil){
        userId = UserStats.currentUser?.authentication.idToken
    }
    guard let id = userId else{
        print("User Not authenticated")
        return
    }
    print("USer ID : \(id)")
    let theUrl = URL(string: "https://www.googleapis.com/books/v1/mylibrary/bookshelves?key=AIzaSyBIDJ50ak-caS3M-6nSVbxdN_SmssAlTRI)")
    if let url = theUrl{
        print("Search Called")
        var urlRequest = URLRequest(url: url)
        urlRequest.httpMethod = "GET"
        urlRequest.setValue(id, forHTTPHeaderField: "Authorization")
        print("URL : " + url.absoluteString)
        let task = URLSession.shared.dataTask(with: urlRequest, completionHandler: {
            (data, response, error) in

            if response != nil{
                if let res = response as? HTTPURLResponse{
                    if(res.statusCode == 408)
                    {
                        MessageBox.Show(message: "Error : Request TimeOut", title: "Error", view: self)
                    }

                }
            }

            if error != nil{
                print("Error \(error?.localizedDescription)")
                MessageBox.Show(message: (error?.localizedDescription)!, title: "An error occurred", view: self)

            }
            else{
                do{

                    let jsonData  = try JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.mutableContainers) as AnyObject
                    print(jsonData)
                }catch{
                }
            }
        }
    }
}

每次我运行代码都会给我错误。错误在这里

{
error =     {
    code = 401;
    errors =         (
                    {
            domain = global;
            location = Authorization;
            locationType = header;
            message = "Invalid Credentials";
            reason = authError;
        }
    );
    message = "Invalid Credentials";
};
}

我正在使用 Google 为 iOS 登录 sdk，这是我尝试进行身份验证并成功完成的方式。

GIDSignIn.sharedInstance().delegate = self
    GIDSignIn.sharedInstance().uiDelegate = self
    GIDSignIn.sharedInstance().clientID = "1049478111900-4q2m623kj5m0fev7fbqq93tk7rgjvs2f.apps.googleusercontent.com"
    GIDSignIn.sharedInstance().scopes.append("https://www.googleapis.com/auth/books")
GIDSignIn.sharedInstance().signIn()

登录成功，因为我确实在成功登录时看到打印成功，而且我还能够检索登录用户的 accessToken 和 idToken。这是我打印的 idToken。

登录用户的 ID 令牌

请帮我解决这个问题。我整夜都在工作，无法解决这个问题。如果有更好的方法或者我可以解决这个问题，请告诉我。

Answer 1

选项 1：

URL(string: "https://www.googleapis.com/books/v1/mylibrary/bookshelves?access_token=YourToken)")

注意：密钥用于public访问访问令牌是私有的你只需要一个

注意 2：您可以通过放置

来测试它

https://www.googleapis.com/books/v1/mylibrary/bookshelves?access_token=YourToken

在任何网络浏览器中。

选项 2：

Header 应该是这样的

Authorization, Bearer accessToken

我认为你缺少承载。

你不需要两者都做，一个就可以。

When sending the access token in the "Authorization" request header field defined by HTTP/1.1 [RFC2617], the client uses the "Bearer" authentication scheme to transmit the access token.

Authorization : Bearer AccessToken
