## 功能特性
|
||||
|
||||
- **Webhook回调**: 实时接收平台事件通知
|
||||
- **开放API**: 通过API密钥访问平台功能
|
||||
- **签名验证**: 确保请求安全可靠
|
||||
- **权限控制**: 细粒度的API访问权限管理
|

|
||||
|
||||

|
||||
|
||||
### 1.2 查询Webhook列表
|
||||
|
||||
**接口**: `GET /api/v1/dev/extension/webhooks?application_id=1`
|
||||
|
||||
**响应示例**:
|
||||
```json
|
||||
{
|
||||
"code": 200,
|
||||
"data": [
|
||||
{
|
||||
"id": 1,
|
||||
"application_id": 1,
|
||||
"name": "商城系统",
|
||||
"url": "https://your-server.com/webhook",
|
||||
"secret_key": "your_secret_key",
|
||||
"events": "[\"user.registered\",\"user.recharged\"]",
|
||||
"status": "active",
|
||||
"retry_count": 3,
|
||||
"timeout": 10,
|
||||
"created_at": "2024-01-01T00:00:00Z"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### 1.3 更新Webhook

||||
|
||||
**接口**: `PUT /api/v1/dev/extension/webhooks/:id`

|
||||
|
||||

|
||||
|
||||

|
||||
|
||||
## 二、Webhook事件
|
||||
|
||||
### 2.1 支持的事件类型
|
||||
|
||||
| 事件代码 | 事件名称 | 触发时机 |
|
||||
|---------|---------|---------|
|
||||
| `user.registered` | 用户注册 | 新用户注册成功时 |
|
||||
| `user.login` | 用户登录 | 用户登录成功时 |
|
||||
| `user.recharged` | 用户充值 | 用户充值成功时 |
|
||||
| `user.expired` | 用户到期 | 用户会员到期时 |
|
||||
| `card.used` | 卡密使用 | 卡密被使用时 |
|
||||
| `card.expired` | 卡密过期 | 卡密过期时 |
|
||||
| `abnormal.detected` | 异常检测 | 检测到异常行为时 |
|
||||
|
||||
### 2.2 回调数据格式
|
||||
|
||||
当事件触发时,平台会向配置的URL发送POST请求:
|
||||
|
||||
```json
|
||||
{
|
||||
"event": "user.registered",
|
||||
"timestamp": 1234567890,
|
||||
"data": {
|
||||
"user_id": 123,
|
||||
"username": "testuser",
|
||||
"email": "test@example.com",
|
||||
"application_id": 1
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 2.3 验证回调请求
|
||||
|
||||
如果配置了`secret_key`,平台会在请求头中添加:
|
||||
|
||||
```
|
||||
X-Webhook-Secret: your_secret_key
|
||||
```
|
||||
|
||||
您的服务器应验证此头部以确保请求来自平台。
|
||||
|
||||

|
||||
|
||||
## 三、API密钥管理
|
||||
|
||||
### 3.1 创建API密钥
|
||||
|
||||
**接口**: `POST /api/v1/dev/extension/api-keys`
|
||||
|
||||
**请求参数**:
|
||||
```json
|
||||
{
|
||||
"application_id": 1,
|
||||
"name": "商城对接",
|
||||
"permissions": ["user.read", "user.recharge"],
|
||||
"expires_at": "2025-12-31T23:59:59Z"
|
||||
}
|
||||
```
|
||||
|
||||
**参数说明**:
|
||||
- `application_id` (必填): 应用ID
|
||||
- `name` (必填): 密钥名称
|
||||
- `permissions` (可选): 权限列表
|
||||
- `expires_at` (可选): 过期时间
|
||||
|
||||
**响应示例**:
|
||||
```json
|
||||
{
|
||||
"code": 200,
|
||||
"data": {
|
||||
"id": 1,
|
||||
"application_id": 1,
|
||||
"name": "商城对接",
|
||||
"access_key": "abc123...",
|
||||
"secret_key": "xyz789...",
|
||||
"permissions": "[\"user.read\",\"user.recharge\"]",
|
||||
"status": "active",
|
||||
"created_at": "2024-01-01T00:00:00Z"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**重要**: `secret_key`只在创建时返回一次,请妥善保存!
|
||||
|
||||
### 3.2 查询API密钥列表
|
||||
|
||||
**接口**: `GET /api/v1/dev/extension/api-keys?application_id=1`
|
||||
|
||||

|
||||
|
||||
**接口**: `DELETE /api/v1/dev/extension/api-keys/:id`
|
||||
|
||||
### 3.5 重新生成密钥
|
||||
|
||||
**接口**: `POST /api/v1/dev/extension/api-keys/:id/regenerate`
|
||||
|
||||
**注意**: 重新生成后,旧密钥立即失效!
|
||||
|
||||
---
|
||||
|
||||
## 四、开放API接口
|
||||
|
||||
### 4.1 认证方式
|
||||
|
||||
所有开放API请求都需要进行签名认证:
|
||||
|
||||
**请求头**:
|
||||
```
|
||||
X-Access-Key: your_access_key
|
||||
X-Signature: calculated_signature
|
||||
X-Timestamp: 1234567890
|
||||
```
|
||||
|
||||
**签名算法**:
|
||||
```javascript
|
||||
// 1. 构造签名字符串
|
||||
const stringToSign = METHOD + PATH + TIMESTAMP + BODY
|
||||
|
||||
// 示例
|
||||
const method = "POST"
|
||||
const path = "/api/v1/ext/user/123/recharge"
|
||||
const timestamp = "1234567890"
|
||||
const body = JSON.stringify({
|
||||
"amount": 100,
|
||||
"type": "points",
|
||||
"description": "商城充值"
|
||||
})
|
||||
|
||||
const stringToSign = method + path + timestamp + body
|
||||
// 结果: "POST/api/v1/ext/user/123/recharge1234567890{\"amount\":100,\"type\":\"points\",\"description\":\"商城充值\"}"
|
||||
|
||||
// 2. 计算签名
|
||||
const signature = HMAC-SHA256(secretKey, stringToSign)
|
||||
```
|
||||
|
||||
**Python示例**:
|
||||
```python
|
||||
import hmac
|
||||
import hashlib
|
||||
import time
|
||||
import json
|
||||
|
||||
def calculate_signature(secret_key, method, path, timestamp, body):
|
||||
string_to_sign = method + path + str(timestamp) + body
|
||||
signature = hmac.new(
|
||||
secret_key.encode('utf-8'),
|
||||
string_to_sign.encode('utf-8'),
|
||||
hashlib.sha256
|
||||
).hexdigest()
|
||||
return signature
|
||||
|
||||
# 使用示例
|
||||
access_key = "your_access_key"
|
||||
secret_key = "your_secret_key"
|
||||
method = "POST"
|
||||
path = "/api/v1/ext/user/123/recharge"
|
||||
timestamp = int(time.time())
|
||||
body = json.dumps({
|
||||
"amount": 100,
|
||||
"type": "points",
|
||||
"description": "商城充值"
|
||||
})
|
||||
|
||||
signature = calculate_signature(secret_key, method, path, timestamp, body)
|
||||
|
||||
headers = {
|
||||
"X-Access-Key": access_key,
|
||||
"X-Signature": signature,
|
||||
"X-Timestamp": str(timestamp),
|
||||
"Content-Type": "application/json"

## 七、最佳实践
|
||||
|
||||
### 7.1 安全建议
|
||||
|
||||
1. **妥善保管密钥**: Secret Key只在创建时显示一次,请立即保存
|
||||
2. **定期更换密钥**: 建议定期重新生成API密钥
|
||||
3. **最小权限原则**: 只授予必要的权限
|
||||
4. **验证Webhook**: 验证回调请求的来源和完整性
|
||||
5. **使用HTTPS**: 确保所有通信都使用HTTPS
|
||||
|
||||
### 7.2 性能优化
|
||||
|
||||
1. **批量操作**: 使用批量接口减少请求次数
|
||||
2. **缓存数据**: 合理缓存用户信息等数据
|
||||
3. **异步处理**: Webhook回调建议异步处理业务逻辑
|
||||
|
||||
### 7.3 错误处理
|
||||
|
||||
1. **重试机制**: 实现请求重试逻辑,处理网络异常
|
||||
2. **日志记录**: 记录所有API请求和响应,便于排查问题
|
||||
3. **超时设置**: 合理设置请求超时时间

## 九、常见问题
|
||||
|
||||
### Q1: 签名验证失败怎么办?
|
||||
|
||||
**A**: 请检查以下几点:
|
||||
1. 确保使用正确的Secret Key
|
||||
2. 确保时间戳是当前Unix时间戳(秒级)
|
||||
3. 确保签名字符串的拼接顺序正确:METHOD + PATH + TIMESTAMP + BODY
|
||||
4. 确保Body是原始JSON字符串,不要格式化或添加空格
|
||||
|
||||
### Q2: Webhook回调失败怎么办?
|
||||
|
||||
**A**:
|
||||
1. 检查回调URL是否可访问
|
||||
2. 查看Webhook日志了解失败原因
|
||||
3. 确保服务器能正确处理POST请求
|
||||
4. 检查是否设置了正确的超时时间
|
||||
|
||||
### Q3: API密钥泄露了怎么办?
|
||||
|
||||
**A**: 立即删除旧密钥并创建新密钥,或者使用"重新生成"功能。
|
||||
|
||||
### Q4: 如何测试API接口?
|
||||
|
||||
**A**: 可以使用Postman、curl等工具,参考本文档中的签名算法构造请求。
