UserInfo接口是OAuth2.0中规定的需要认证访问的接口,可以返回认证用户的声明信息。请求UserInfo接口需要使用通行令牌。响应报文通常是json数据格式,包含了一组claim键值对集合。与UserInfo接口通讯必须使用https。
根据RFC2616协议,UserInfo必须支持GET和POST方法。
UserInfo接口必须接受Bearer令牌。
UserInfo接口应该支持javascript客户端跨域访问,可以使用CORS协议或者其他方案。
推荐使用GET方法,使用Authorization头承载Bearer令牌来请求UserInfo接口。
GET /userinfo HTTP/1.1
Host: server.example.com
Authorization: Bearer SlAV32hkKG
如果某个claim为空或者null,不返回该键。
必须返回sub(subject)声明。
必须校验UserInfo返回的sub与id_token中的sub是否一致
content-type必须是application/json,必须使用utf-8编码
如果加密位jwt返回,content-type必须位application/jwt
HTTP/1.1 200 OK
Content-Type: application/json
{
"sub": "248289761001",
"name": "Jane Doe",
"given_name": "Jane",
"family_name": "Doe",
"preferred_username": "j.doe",
"email": "janedoe@example.com",
"picture": "http://example.com/janedoe/me.jpg"
}
HTTP/1.1 401 Unauthorized
WWW-Authenticate: error="invalid_token",
error_description="The Access Token expired"
客户端必须校验如下内容
Authorizaton
头中获取Bearer Token
的值,找到的话则返回access_token
参数值Beaer Token
的话则返回校验失败结果public async Task<BearerTokenUsageValidationResult> ValidateAsync(HttpContext context)
{
var result = ValidateAuthorizationHeader(context);
if (result.TokenFound)
{
_logger.LogDebug("Bearer token found in header");
return result;
}
if (context.Request.HasFormContentType)
{
result = await ValidatePostBodyAsync(context);
if (result.TokenFound)
{
_logger.LogDebug("Bearer token found in body");
return result;
}
}
_logger.LogDebug("Bearer token not found");
return new BearerTokenUsageValidationResult();
}
由IUserInfoRequestValidator
的默认实现UserInfoRequestValidator
对入参进行校验。
accessToken
,必须包括openid
声明的权限sub
声明,sub
是subject
的缩写,代表用户唯一标识accessToken
所有claim
,移除以下与用户信息无关的claim
。claim
创建名称为UserInfo
的Principal
IProfileService
的IsAcriveAsync
方法判断用户是否启用,不是启动状态的话返回invalid_token
错误Principal
public async Task<UserInfoRequestValidationResult> ValidateRequestAsync(string accessToken)
{
// the access token needs to be valid and have at least the openid scope
var tokenResult = await _tokenValidator.ValidateAccessTokenAsync(
accessToken,
IdentityServerConstants.StandardScopes.OpenId);
if (tokenResult.IsError)
{
return new UserInfoRequestValidationResult
{
IsError = true,
Error = tokenResult.Error
};
}
// the token must have a one sub claim
var subClaim = tokenResult.Claims.SingleOrDefault(c => c.Type == JwtClaimTypes.Subject);
if (subClaim == null)
{
_logger.LogError("Token contains no sub claim");
return new UserInfoRequestValidationResult
{
IsError = true,
Error = OidcConstants.ProtectedResourceErrors.InvalidToken
};
}
// create subject from incoming access token
var claims = tokenResult.Claims.Where(x => !Constants.Filters.ProtocolClaimsFilter.Contains(x.Type));
var subject = Principal.Create("UserInfo", claims.ToArray());
// make sure user is still active
var isActiveContext = new IsActiveContext(subject, tokenResult.Client, IdentityServerConstants.ProfileIsActiveCallers.UserInfoRequestValidation);
await _profile.IsActiveAsync(isActiveContext);
if (isActiveContext.IsActive == false)
{
_logger.LogError("User is not active: {sub}", subject.GetSubjectId());
return new UserInfoRequestValidationResult
{
IsError = true,
Error = OidcConstants.ProtectedResourceErrors.InvalidToken
};
}
return new UserInfoRequestValidationResult
{
IsError = false,
TokenValidationResult = tokenResult,
Subject = subject
};
}
调用IUserInfoResponseGenerator
接口的默认实现UserInfoResponseGenerator
的ProcessAsync
方法生成响应报文。
scope
声明值,查询scope
值关联的IdentityResource
(身份资源)及其关联的所有claim
。得到的结果就是用户请求的所有claim
DefaultProfileService
的GetProfileDataAsync
方法,返回校验结果claim
与用户请求claim
的交集。claim
集合中没有sub
,取校验结果中的sub
值。如果IProfileService
返回的sub
声明值与校验结果的sub
值不一致抛出异常。claim
集合。Cache-Control:no-store, no-cache, max-age=0
,Pragma:no-cache
claim
集合用json格式写入响应内容 public virtual async Task<Dictionary<string, object>> ProcessAsync(UserInfoRequestValidationResult validationResult)
{
Logger.LogDebug("Creating userinfo response");
// extract scopes and turn into requested claim types
var scopes = validationResult.TokenValidationResult.Claims.Where(c => c.Type == JwtClaimTypes.Scope).Select(c => c.Value);
var requestedClaimTypes = await GetRequestedClaimTypesAsync(scopes);
Logger.LogDebug("Requested claim types: {claimTypes}", requestedClaimTypes.ToSpaceSeparatedString());
// call profile service
var context = new ProfileDataRequestContext(
validationResult.Subject,
validationResult.TokenValidationResult.Client,
IdentityServerConstants.ProfileDataCallers.UserInfoEndpoint,
requestedClaimTypes);
context.RequestedResources = await GetRequestedResourcesAsync(scopes);
await Profile.GetProfileDataAsync(context);
var profileClaims = context.IssuedClaims;
// construct outgoing claims
var outgoingClaims = new List<Claim>();
if (profileClaims == null)
{
Logger.LogInformation("Profile service returned no claims (null)");
}
else
{
outgoingClaims.AddRange(profileClaims);
Logger.LogInformation("Profile service returned the following claim types: {types}", profileClaims.Select(c => c.Type).ToSpaceSeparatedString());
}
var subClaim = outgoingClaims.SingleOrDefault(x => x.Type == JwtClaimTypes.Subject);
if (subClaim == null)
{
outgoingClaims.Add(new Claim(JwtClaimTypes.Subject, validationResult.Subject.GetSubjectId()));
}
else if (subClaim.Value != validationResult.Subject.GetSubjectId())
{
Logger.LogError("Profile service returned incorrect subject value: {sub}", subClaim);
throw new InvalidOperationException("Profile service returned incorrect subject value");
}
return outgoingClaims.ToClaimsDictionary();
}
