是否有任何其他参数需要设置

string state = "882158738|0.380667456";
string scope = "https://www.googleapis.com/auth/drive.readonly";
string redirect_uri = "APIAddress";
string GoogleClientID= "your ClientID";

string oauthUrl = string.Format("https://accounts.google.com/o/oauth2/auth?" +
                                   "scope={0}&state={1}&redirect_uri={2}&response_type=code&client_id={3}&approval_prompt=force&access_type=offline",
HttpUtility.HtmlEncode("scope"),
state,
HttpUtility.HtmlEncode(redirect_uri ),
HttpUtility.HtmlEncode(GoogleClientID));

return oauthUrl ;
