如何在 C#（Windows 窗体）的 Google OAuth 中添加配置文件范围和电子邮件范围

Question

如何在 Google OAuth 中添加配置文件范围和电子邮件范围，我正在使用下面给出的代码。

        string tokenRequestURI = "https://www.googleapis.com/oauth2/v4/token";
        string tokenRequestBody = string.Format("code={0}&redirect_uri={1}&client_id={2}&code_verifier={3}&client_secret={4}&scope=&grant_type=authorization_code",
            code,
            System.Uri.EscapeDataString(redirectURI),
            clientID,
            code_verifier,
            clientSecret
            );

        // sends the request
        HttpWebRequest tokenRequest = (HttpWebRequest)WebRequest.Create(tokenRequestURI);
        tokenRequest.Method = "POST";
        tokenRequest.ContentType = "application/x-www-form-urlencoded";
        tokenRequest.Accept = "Accept=text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
        byte[] _byteVersion = Encoding.ASCII.GetBytes(tokenRequestBody);
        tokenRequest.ContentLength = _byteVersion.Length;
        Stream stream = tokenRequest.GetRequestStream();
        await stream.WriteAsync(_byteVersion, 0, _byteVersion.Length);
        stream.Close();

您没有在您的 tokenRequestBody 中发送任何范围您是否尝试将它们添加到那里？

string tokenRequestBody = string.Format("code={0}&redirect_uri={1}&client_id={2}&code_verifier={3}&client_secret={4}&scope={5}&grant_type=authorization_code",
        code,
        System.Uri.EscapeDataString(redirectURI),
        clientID,
        code_verifier,
        clientSecret,
        "email profile"
        );

您应该真正考虑使用 Google .net 客户端库，而不是全部手动完成。
