如何在没有密码的情况下从服务器手动生成access_token?
我想允许超级管理员作为用户登录并查看他们的问题,并通过他们的眼睛看到问题,因此我需要用户access_token。我已经看到了这个question,但是在IdentityServer3中没有帮助我。
最佳答案
首先创建一个名为loginBy的自定义授予
public class LoginByGrant : ICustomGrantValidator
{
private readonly ApplicationUserManager _userManager;
public string GrantType => "loginBy";
public LoginByGrant(ApplicationUserManager userManager)
{
_userManager = userManager;
}
public async Task<CustomGrantValidationResult> ValidateAsync(ValidatedTokenRequest request)
{
var userId = Guid.Parse(request.Raw.Get("user_id"));
var user = await _userManager.FindByIdAsync(userId);
if (user == null)
return await Task.FromResult<CustomGrantValidationResult>(new CustomGrantValidationResult("user not exist"));
var userClaims = await _userManager.GetClaimsAsync(user.Id);
return
await Task.FromResult<CustomGrantValidationResult>(new CustomGrantValidationResult(user.Id.ToString(), "custom", userClaims));
}
}
然后在身份启动类中添加此自定义授予
factory.CustomGrantValidators.Add(
new Registration<ICustomGrantValidator>(resolver => new LoginByGrant(ApplicaionUserManager)));
最后在你的api中
public async Task<IHttpActionResult> LoginBy(Guid userId)
{
var tokenClient = new TokenClient(Constants.TokenEndPoint, Constants.ClientId, Constants.Secret);
var payload = new { user_id = userId.ToString() };
var result = await tokenClient.RequestCustomGrantAsync("loginBy", "customScope", payload);
if (result.IsError)
return Ok(result.Json);
return Ok(new { access_token = result.AccessToken, expires_in = result.ExpiresIn});
}
这是用于identityServer3,但对于identityServer4,它非常相似
