blade-auth-client
blade-auth-client 是 Blade 生态的共享 Casdoor 认证客户端包。它抽离了统一的 token 校验、FastAPI 装配和 Socket.IO 握手接口,供各个服务复用。
安装
pip install blade-auth-client[fastapi,socketio]
Casdoor 配置要求
Casdoor 的 application、scope 和 redirect URI 约束见 docs/casdoor-setup.md。
快速上手(0.4.0+)
from fastapi import FastAPI, Depends
from blade_auth_client import AuthConfig, BladeAuth, CasdoorClaims, LazyProvisioner
class MyProvisioner(LazyProvisioner["MyUser"]):
async def provision_user(self, claims: CasdoorClaims) -> "MyUser":
# 首次登录:建用户并绑定 claims.sub;非首次:查出来刷字段
...
auth = BladeAuth(
AuthConfig.from_yaml("configs/oauth_config.yaml"),
provisioner=MyProvisioner(),
)
app = FastAPI()
app.include_router(auth.router, prefix="/api/v1/auth")
@app.get("/me")
def me(user = auth.require()):
return user
详细流程见 docs/接入指南.md;多 app 共享鉴权 / BladeAuth 设计背景见 docs/设计/设计-API暴露面收敛.md。
从 0.3.x 升级
- 推荐迁到
BladeAuthfacade(上面那段)。老零件(OidcClient/TokenVerifier/create_auth_router/make_require_auth_dep/ 等)0.4.0 仍可从顶层 import,但会DeprecationWarning,0.5.0 移除。 LazyProvisioner.ensure_user→provision_user。老名字继续可用且 SDK 内部自动回落,调用时 warn 一次。
Web 会话与组织
系统里有两类长期凭据,生命周期不同,别混用:
| web 令牌 | PAT | |
|---|---|---|
| 是什么 | 密码登录换来的 RS256 JWT | 不透明的 sk-blade-v3-… |
| 代表 | 某人这次登录 | 某人这个身份 |
logout 后 |
立即失效 | 不受影响 |
| 适合 | 网页 / 客户端会话 | 脚本、服务间调用 |
会话用 web 令牌、自动化用 PAT。拿 PAT 当会话使,用户点了登出也退不掉;拿 web 令牌做自动化,用户一登出你的定时任务就断了。
from blade_auth_client import SessionClient, OrgClient
from blade_auth_client.session import AccountLockedError
from blade_auth_client.errors import InvalidTokenError
sc = SessionClient("http://blade-oauth:19000")
try:
token = await sc.login("alice", "secret")
except AccountLockedError: # 429:连续失败被冻结
...
except InvalidTokenError: # 401:账号或密码不对
...
me = await sc.me(token.access_token) # SessionUser(含 source / source_id)
await sc.logout(token.access_token) # 服务端拉黑,之后一律 401
logout 只作用于传入的这一枚令牌:同一用户在别处的会话、以及他的 PAT 都不受
影响。需要「所有设备下线」用管理端的 DELETE /api/v1/users/{id}/sessions。
重复登出不报错——登出表达的是意图,令牌本来就无效同样满足这个意图。
本地口令校验不过时,blade-oauth 会转发给管理员配置的外部认证源,认证通过即自动
建号;对调用方没有区别,拿到的始终是 blade-oauth 自己签的令牌。SessionUser.source
告诉你这个账号从哪来(admin_api / bootstrap / external / legacy)。
oc = OrgClient("http://blade-oauth:19000")
roster = await oc.my_members(token) # 我同组织的人,普通用户可调
orgs = await oc.list(admin_token) # 需要 admin
org = await oc.get(admin_token, "org-a")
members = await oc.members(admin_token, "org-a")
my_members 返回脱敏视图——OrgMember 刻意没有邮箱、手机、额度等字段,
避免花名册被当成全公司通讯录来爬。注意判断 OrgRoster.truncated:花名册上限
500 人,服务端会如实告诉你名单是否被截断。
版本策略
0.0.x 版本仅用于占位发布和联调验证,不承诺可用性。0.2.0 起采用仅校验 iss + 签名 + exp 的简化策略。
发布
仓库已经预留了 GitHub Actions 发布流水线:
- PR 校验:
.github/workflows/python-sdk-ci.yml - PyPI 发布:
.github/workflows/python-sdk-publish.yml
首次配置 Trusted Publishing 时,在 PyPI 项目的 Publishing 页面添加 GitHub publisher,填写:
- Owner:
blade-hq - Repository name:
blade-oauth - Workflow name:
python-sdk-publish.yml
日常发版流程:
# 1. 修改 sdk/python/pyproject.toml 里的 version
# 2. 推送代码到默认分支后,创建并推送同版本 tag
git tag blade-auth-client-vX.Y.Z
git push origin blade-auth-client-vX.Y.Z
发布 workflow 会校验 tag 版本与 pyproject.toml 一致,然后自动构建并发布到 PyPI。
