The token you're trying to parse is a struct
您尝试解析的令牌是一个结构体
the actualtoken is:
在实际的令牌是：
accessToken.authenticationToken
your code should be like that:
你的代码应该是这样的：
let loginManager = LoginManager()
loginManager.logIn([ .publicProfile, .userFriends, .email ], viewController: self) { loginResult in
switch loginResult {
case .failed(let error):
print(error)
case .cancelled:
print("User cancelled login.")
case .success(let grantedPermissions, let declinedPermissions, let accessToken):
print("accessToken: " + accessToken.authenticationToken)
break
}
}
