Ory Kratos 為使用者認證與管理系統。本文將動手實現瀏覽器(React+AntD)的完整流程,實際瞭解下它的 API 。
瞭解 Kratos
獲取程式碼
git clone -b v0.7.0-alpha.1 --depth 1 https://github.com/ory/kratos.git
檢視 API
go-swagger 檢視:
cd kratos
swagger serve -F=swagger ./spec/swagger.json
執行服務
docker-compose 執行:
cd kratos
docker-compose -f quickstart.yml -f quickstart-postgres.yml -f quickstart-standalone.yml up --build --force-recreate
# If you have SELinux, run: -f quickstart-selinux.yml
運行了官方 Quickstart 例子,可以訪問 http://127.0.0.1:4455/dashboard 體驗。
檢視 DB
pgAdmin 開啟(DB 資訊見 quickstart-postgres.yml
):
查看錶:
檢視配置
cd kratos
cat contrib/quickstart/kratos/email-password/kratos.yml
設定環境變數可以覆蓋。以 _
表示層級,如 SELFSERVICE_FLOWS_SETTINGS_UI_URL=<value>
覆蓋 selfservice.flows.settings.ui_url
。
Self-Service 流程
- Registration
- Login
- Logout
- User Settings
- Account Recovery
- Address Verification
- User-Facing Error
- 2FA / MFA
瀏覽器流程
客戶端流程
動手配置:Kratos 服務
- Ory Kratos
- Public API (port 4433)
- Admin API (port 4434)
- Postgres DB (port 5432)
- Browser Return URL (port 3000)
- MailSlurper: a development SMTP server
- Server UI (port 4436)
配置檔案
- ory-kratos/config/kratos.yml: 配置檔案
- ory-kratos/config/identity.schema.json: 認證 JSON 模式
啟動檔案
- ory-kratos/start.yml: Docker Compose 檔案
執行服務
cd ory-kratos
docker-compose -f start.yml up --build --force-recreate
如果想執行官方 Self-Service UI 例子,那麼:
docker-compose -f start.yml -f start-ui-node.yml up --build --force-recreate
之後,訪問 http://127.0.0.1:3000/ 體驗。在 Register new account
/ Reset password
時,可訪問虛擬 SMTP 服務 http://127.0.0.1:4436 接收郵件。
動手實現:瀏覽器流程
新建 React 應用
yarn create react-app my-web --template typescript
cd my-web
yarn start
訪問 http://localhost:3000/ ,可見 React 歡迎頁。
引入 AntD
yarn add antd
修改 src/App.tsx
,引入 antd 元件:
import React, { Component } from 'react'
import { Button } from 'antd';
import logo from './logo.svg';
import './App.css';
class App extends Component {
render() {
return (
<div className="App">
<header className="App-header">
<img src={logo} className="App-logo" alt="logo" />
<Button type="primary">Button</Button>
</header>
</div>
);
}
}
export default App;
修改 src/App.css
,引入 antd 樣式:
@import '~antd/dist/antd.css';
可見 antd 藍色按鈕元件。
引入 Sass
yarn add node-sass
字尾 css
改為 scss
,tsx
裡的 import
也改下。
引入 Router
yarn add react-router-dom @types/react-router-dom
於 pages
目錄下實現如下頁面 UI:
src/pages 功能 路由
├── dashboard.tsx 主頁 /, /dashboard
├── error.tsx 錯誤 /error
├── login.tsx 登入 /auth/login
├── recovery.tsx 恢復 /recovery
├── registration.tsx 註冊 /auth/registration
├── settings.tsx 設定 /settings
└── verification.tsx 驗證 /verify
引入 SDK
yarn add @ory/[email protected]
註冊
APIs:
GET
/self-service/registration/browser
: 初始化註冊流程GET
/self-service/registration/flows
: 獲取註冊流程POST
/self-service/registration
: 提交註冊流程
頁面載入後的處理流程:
componentDidMount() {
// 獲取 flow id 引數
const flowId = utils.parseUrlQuery("flow", this.props.location) as string;
// 沒有 flow id,初始化註冊流程
if (!flowId || !utils.isString(flowId)) {
console.log("No flow ID found in URL, initializing registration flow.");
utils.redirectToSelfService("/self-service/registration/browser");
return;
}
// 根據 flow id,獲取註冊流程資訊
authPublicApi
.getSelfServiceRegistrationFlow(flowId, undefined, {
withCredentials: true,
})
.then((res: AxiosResponse<SelfServiceRegistrationFlow>) => {
if (utils.assertResponse(res)) {
utils.redirectToSelfService("/self-service/registration/browser");
return;
}
this.setState({ flowId: flowId, flow: res.data });
})
.catch(utils.redirectOnError);
}
流程資訊 this.state.flow
,如下:
{
"id": "74c643a1-f302-45c9-a760-1ad7b1157e1c",
"type": "browser",
"expires_at": "2021-07-20T05:22:30.958717Z",
"issued_at": "2021-07-20T05:12:30.958717Z",
"request_url": "http://127.0.0.1:4433/self-service/registration/browser",
"ui": {
"action": "http://127.0.0.1:4433/self-service/registration?flow=74c643a1-f302-45c9-a760-1ad7b1157e1c",
"method": "POST",
"nodes": [{
"type": "input",
"group": "default",
"attributes": {
"name": "csrf_token",
"type": "hidden",
"value": "QQyUDHa4KJ3M6mowHHN4pboN4iaUOZL+4gYVtKYRWzSdWjSNcW5dG/SNzocyqqqAtV48KzQVMIC6X+Pv3tNPNw==",
"required": true,
"disabled": false
},
"messages": [],
"meta": {}
}, {
"type": "input",
"group": "password",
"attributes": {
"name": "traits.email",
"type": "email",
"disabled": false
},
"messages": [],
"meta": {
"label": {
"id": 1070002,
"text": "E-Mail",
"type": "info"
}
}
}, {
...
}]
}
}
之後,依據流程資訊建立表單:
<Card title="Register new account" bordered={false}>
{/* 流程訊息展示 */}
{this.state.flow.ui.messages &&
this.state.flow.ui.messages.map((m: UiText, index) => (
<Alert
key={index}
message={m.text}
type={m.type as AlertProps["type"]}
style={{ marginBottom: 16 }}
showIcon
/>
))}
{/* 流程表單建立 */}
<Form
name="register"
ref={this.formRef}
encType="application/x-www-form-urlencoded"
action={this.state.flow.ui.action}
method={this.state.flow.ui.method}
onFinish={onFinish}
>
{this.state.flow.ui.nodes.map((node, index) => {
return React.cloneElement(ui.toUiNodeAntd(node)!, {
key: index,
});
})}
</Form>
</Card>
其中表單 onFinish
裡處理提交:
const onFinish = (values: any) => {
// 因 AntD Form 不提交原 HTML form,所以自己建立 from 提交
// - 不能直接 find form 提交,此時值已清空
// - 建立 from 提交,與 AntD From 相互無影響
ui.submitViaForm(this.state.flow!.ui, values);
// 或者,用 `/self-service/registration/api` 提交
// this.submitViaApi(values);
};
登入
GET
/self-service/login/browser
: 初始化登入流程GET
/self-service/login/flows
: 獲取登入流程POST
/self-service/login
: 提交登入流程
與註冊流程一樣。
登入後,可通過 whoami
獲取授權資訊:
GET
/sessions/whoami
: 獲取授權資訊
authPublicApi
.toSession(undefined, undefined, {
withCredentials: true,
})
.then((res: AxiosResponse<Session>) => {
if (utils.assertResponse(res)) {
utils.redirectToSelfService("/self-service/login/browser");
return;
}
this.setState({ session: res.data });
})
.catch((err: AxiosError) => utils.redirectOnError(err, "/auth/login"));
Dashboard
頁展示了授權資訊:
驗證
GET
/self-service/verification/browser
: 初始化驗證流程GET
/self-service/verification/flows
: 獲取驗證流程POST
/self-service/verification
: 提交驗證流程
與註冊流程一樣。
恢復
GET
/self-service/recovery/browser
: 初始化恢復流程GET
/self-service/recovery/flows
: 獲取恢復流程POST
/self-service/recovery
: 提交恢復流程
與註冊流程一樣。
設定
GET
/self-service/settings/browser
: 初始化設定流程GET
/self-service/settings/flows
: 獲取設定流程POST
/self-service/settings
: 完成設定流程
與註冊流程一樣。
但要注意的是,依據流程資訊建立表單時,請區分 group
構建多個表單:
const nodesGroup: Record<
string,
{
title?: string;
nodes?: Array<UiNode>;
}
> = {
default: {},
profile: { title: "Profile" },
password: { title: "Password" },
oidc: { title: "Social Sign In" },
};
for (const [k, v] of Object.entries(nodesGroup)) {
nodesGroup[k] = {
title: v.title,
nodes: ui.onlyNodes(this.state.flow!.ui.nodes, k),
};
}
<Card title="Settings" bordered={false}>
{this.state.flow.ui.messages &&
this.state.flow.ui.messages.map((m: UiText, index) => (
<Alert
key={index}
message={m.text}
type={m.type as AlertProps["type"]}
style={{ marginBottom: 16 }}
showIcon
/>
))}
{/* Split Form by group here. Otherwise, one AntD Form method conflicts. */}
{Object.entries(nodesGroup)
.filter(([k, v]) => k !== "default" && v && v.nodes!.length > 0)
.map(([k, v], index) => (
<Form
key={index}
name={k}
encType="application/x-www-form-urlencoded"
action={this.state.flow!.ui.action}
method={this.state.flow!.ui.method}
onFinish={onFinish}
>
<Form.Item>
<div>{v.title}</div>
</Form.Item>
{v
.nodes!.concat(nodesGroup["default"].nodes!)
.map((node, index) => {
return React.cloneElement(ui.toUiNodeAntd(node)!, {
key: index,
});
})}
</Form>
))}
</Card>
登出
GET
/self-service/logout/browser
: 建立登出 URLPOST
/self-service/logout
: 完成登出流程
頁面載入後建立登出 URL ,
authPublicApi
.createSelfServiceLogoutFlowUrlForBrowsers(undefined, {
withCredentials: true,
})
.then((res: AxiosResponse<SelfServiceLogoutUrl>) => {
this.setState({ logoutUrl: res.data.logout_url });
})
.catch((err) => {
// console.log(err);
});
之後,頁面加上登出按鈕:
{this.state.logoutUrl && (
<Button
type="link"
shape="circle"
href={this.state.logoutUrl}
icon={<LogoutOutlined />}
/>
)}
