### 使用示例
|
||||
|

# 使用默认配置
|
||||
cargo run
|
||||
|
||||
# 使用指定配置文件
|
||||
cargo run -- config.toml
|
||||
|
||||
# 使用JavaScript配置
|
||||
cargo run -- config.js
|
||||
```
|
||||
|
||||
#### 测试
|
||||
```bash
|
||||
# 运行所有测试
|
||||
cargo test
|
||||
|
||||
# 运行单个测试
|
||||
cargo test test_name
|
||||
|
||||
# 代码检查
|
||||
cargo clippy
|
||||
|
||||
# 代码格式化
|
||||
cargo fmt

### 📚 新增v0.2.0功能
|
||||
|
||||
#### TCP/WebSocket代理
|
||||
```toml
|
||||
[[sites."ws.example.com".routes]]
|
||||
type = "tcp_proxy"
|
||||
path_pattern = "/ws/*"
|
||||
target = "ws://websocket-server:8080"
|
||||
protocol = "websocket" # tcp, websocket, http
|
||||
```
|
||||
|
||||
#### 连接池配置
|
||||
```toml
|
||||
[connection_pool]
|
||||
max_connections = 100
|
||||
idle_timeout = 90 # 秒
|
||||
```
|
||||
|
||||
#### 负载均衡配置
|
||||
```toml
|
||||
[[sites."api.example.com".routes]]
|
||||
type = "reverse_proxy"
|
||||
path_pattern = "/api/*"
|
||||
target = "http://primary-backend"
|
||||
|
||||
[sites."api.example.com".routes.load_balancer]
|
||||
strategy = "least_connections" # round_robin, least_connections, weighted_round_robin, ip_hash, random
|
||||
upstreams = [
|
||||
"http://backend1:3000",
|
||||
"http://backend2:3000",
|
||||
"http://backend3:3000"
|
||||
]
|
||||
weights = [3, 2, 1] # 可选权重配置
|
||||
```
|
||||
|
||||
#### 健康检查配置
|
||||
```toml
|
||||
[health_check]
|
||||
interval = 30 # 秒
|
||||
timeout = 5 # 秒
|
||||
path = "/health"
|
||||
expected_status = 200
|
||||
```
|
||||
|
||||
### 🔄 升级指南 (v0.1.0 → v0.2.0)
|
||||
|
||||
#### 配置更新
|
||||
v0.2.0新增了`connection_pool`和`health_check`配置字段，如果使用自定义配置，请更新：
|
||||
|
||||
```toml
|
||||
# v0.1.0 配置
|
||||
port = 8080
|
||||
[sites."example.com"]
|
||||
|
||||
# v0.2.0 配置 (新增字段)
|
||||
port = 8080
|
||||
[sites."example.com"]
|
||||
|
||||
[connection_pool]
|
||||
max_connections = 100
|
||||
idle_timeout = 90
|
||||
|
||||
[health_check]
|
||||
interval = 30
|
||||
timeout = 5
|
||||
path = "/health"
|
||||
expected_status = 200
|
||||
```
|
||||
|
||||
#### API变更
|
||||
- **TCP代理**: 新增`TcpProxyManager`和相关功能
|
||||
- **连接池**: 新增`ConnectionPool`用于HTTP连接管理
|
||||
- **负载均衡**: 新增`LoadBalancer`支持多种算法
|
||||
- **健康检查**: 新增`HealthChecker`用于服务监控
|
||||
|
||||
#### 行为变更
|
||||
- 配置文件新增字段为可选，向后兼容
|
||||
- 现有配置继续工作
|
||||
- 新功能默认禁用，需显式配置
|
