项目环境 ###:
ASP.NetCore 3.1
IdentityServer4 4.0.0+
主题内容
测试登录方式 : password
错误内容:
connect/token 登陆出错
但百度/google网上的示例没有找到正确的调用方式，无奈只能自己动手，丰衣足食...
首先，先按照之前版本进行传参
- POST请求
- url: connect/token
- 参数传递通过 form-data
调用结果:
<调用结果>
HTTP : 400
{
"error": "invalid_request"
}
查找调用日志
Invoking IdentityServer endpoint: IdentityServer4.Endpoints.TokenEndpoint for /connect/token
可以看到地址匹配是成功的，那就是校验不通过了，接着看一下这个类的源码，找到错误触发地
public async Task<IEndpointResult> ProcessAsync(HttpContext context)
{
if (!HttpMethods.IsPost(context.Request.Method) || !context.Request.HasApplicationFormContentType())
{
return Error("invalid_request");
}
}
此处有两个验证:
- POST请求 √
- HasApplicationFormContentType ？
查看方法定义:
internal static bool HasApplicationFormContentType(this HttpRequest request)
{
if (request.ContentType == null)
{
return false;
}
if (MediaTypeHeaderValue.TryParse(request.ContentType, out MediaTypeHeaderValue parsedValue))
{
return parsedValue.MediaType.Equals("application/x-www-form-urlencoded", StringComparison.OrdinalIgnoreCase);
}
return false;
}
... 好样的，最新版改用了application/x-www-form-urlencoded传参
然后改一下传参方式接着调用:
<调用结果>
HTTP : 400
{
"error": "invalid_scope"
}
换了个错误，至少说明传参改动还是有效的...
查找操作日志：
IdentityServer4.Validation.TokenRequestValidator
No scopes found in request
key code:
string text = parameters.Get("scope");
if (text.IsMissing())
{
text = clientAllowedScopes.Distinct().ToSpaceSeparatedString();
}
List<string> requestedScopes = text.ParseScopesString();
if (requestedScopes == null)
{
LogError("No scopes found in request");
return false;
}
scope取值:
如果没有传值，就去client中取
public static List<string> ParseScopesString(this string scopes)
{
if (scopes.IsMissing())
{
return null;
}
scopes = scopes.Trim();
List<string> list = scopes.Split(new char[1]
{
' '
}, StringSplitOptions.RemoveEmptyEntries).Distinct().ToList();
if (list.Any())
{
list.Sort();
return list;
}
return null;
}
如果有传值 就用传值的获取，多个scope用' '分隔
在配置中，是有AllowedScopes配置，但取不出来？ 先不管，用传值方式先试试...
<调用结果>
HTTP : 400
{
"error": "invalid_scope"
}
??? 再查下日志:
IdentityServer4.Validation.DefaultResourceValidator
Scope api1 not found in store.
还好错误变了，不然没得玩了...
先确认配置信息:
return new List<ApiResource>
{
new ApiResource("api1", "My API")
};
是有这个api1的，好吧，只能再去查看源码了
DefaultResourceValidator Scope验证分析
IdentityResource identity = resourcesFromStore.FindIdentityResourcesByScope(requestedScope.ParsedName);
if (identity != null)
{
if (await IsClientAllowedIdentityResourceAsync(client, identity))
{
result.ParsedScopes.Add(requestedScope);
result.Resources.IdentityResources.Add(identity);
}
else
{
result.InvalidScopes.Add(requestedScope.RawValue);
}
return;
}
首先先通过name去拿IdentityResource，拿到了IdentityResource验证结果即为最终结果
ApiScope apiScope = resourcesFromStore.FindApiScope(requestedScope.ParsedName);
没有拿到IdentityResource则再通过name去拿ApiScope,验证结果即为最终结果
把IdentityResource的Name值配置到Client中的AllowedScopes去，然后再在传参里使用IdentityResource的Name值
<调用结果>

"access_token": "eyJhbGciOiJSUzI1NiIsImtpZCI6IjUyM0EzMjE0Q0M4MzAzQjJBRDA2Mzk5N0E2RDI1NDEyIiwidHlwIjoiYXQrand0In0.eyJuYmYiOjE1OTQxMTAwNjcsImV4cCI6MTU5NDExMzY2NywiaXNzIjoiaHR0cDovL2xvY2FsaG9zdDo1MDAwIiwiY2xpZW50X2lkIjoicm8uY2xpZW50Iiwic3ViIjoiMiIsImF1dGhfdGltZSI6MTU5NDExMDA2NywiaWRwIjoibG9jYWwiLCJqdGkiOiJCMEY1NEI2NDI1QzUwRDU2REVEMjBGQUY0QkMwNTE5MiIsImlhdCI6MTU5NDExMDA2Nywic2NvcGUiOlsib3BlbmlkIl0sImFtciI6WyJwd2QiXX0.PqYMwqHfZ3CHtE8q_eCi5H1FVCPKe01uSPiSTNjV0q1m61s98OQezo9M3FCc4bGTw4c6VruylSQAbtT6sid2nYXV05Eq_fD_4KKPTya6NLuTdwgdUohzNN10f3SC0ea1nDhv_94Ewkov_9OWrCSLxAX9yVFKDDs6dB3V53_49n4-3Hd9BkCOevWk-_FzpkMOOhYMi-5LNeZRAXH3G5_GZ7INtypCUx2f0_v84UzQxx2LjcovzAy0ZR3GgFvAh5rgRwd5oBVeiLZOt2ZjvV0b5NAtPSbiEcufFK5box6qm_q2M6GrrMBUm0aTTTd3Vu6Zx-pjjITHQN934EICRKWYFg",
"expires_in": 3600,
"token_type": "Bearer",
"scope": "openid"
}
over... 总算通了
总结
- 传参需要使用 application/x-www-form-urlencoded
- 配置Client的AllowedScopes值时要使用IdentityResource的Name值，或者配置ApiScope
- 传参传scope时，通过制指定scope进行验证,未传时通过配置的信息(AllowedScopes)进行验证
新版的ApiResource作用
待补充...
