目前,我正在遵循这篇文章https://dev.outlook.com/restapi/tutorial/dotnet。除了无法从访问令牌中检索用户的电子邮件地址外,一切都很顺利。
private string GetEmailFromIdToken(string token) {
// JWT is made of three parts, separated by a '.'
// First part is the header
// Second part is the token
// Third part is the signature
string[] tokenParts = token.Split('.');
if (tokenParts.Length < 3) {
// Invalid token, return empty
}
// Token content is in the second part, in urlsafe base64
string encodedToken = tokenParts[1];
// Convert from urlsafe and add padding if needed
int leftovers = encodedToken.Length % 4;
if (leftovers == 2) {
encodedToken += "==";
} else if (leftovers == 3) {
encodedToken += "=";
}
encodedToken = encodedToken.Replace('-', '+').Replace('_', '/');
// Decode the string
var base64EncodedBytes = System.Convert.FromBase64String(encodedToken);
string decodedToken = System.Text.Encoding.UTF8.GetString(base64EncodedBytes);
// Load the decoded JSON into a dynamic object
dynamic jwt = Newtonsoft.Json.JsonConvert.DeserializeObject(decodedToken);
// User's email is in the preferred_username field
return jwt.preferred_username;
}
在一些文章中,人们建议添加“openid”
private static string[] scopes = { "openid", "https://outlook.office.com/mail.read",
"https://outlook.office.com/calendars.read" };
在作用域内。然而,它仍然无法工作。它甚至不能成功登录,会抛出异常。 当我不添加“openid”时,我可以成功登录,但“preferred_username”为空。
