多目标配置

IoM在0.1.2版本开始支持多服务器配置。当主服务器失效时，会自动切换到备用服务器。

注意: 目前只能同时启用一种通信协议，不同协议的配置需要分别使用。

HTTP 协议

基础配置

targets:
  - address: "127.0.0.1:8080"
    http:
      method: "POST"
      path: "/"
      version: "1.1"
      headers:
        User-Agent: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36"
        Content-Type: "application/octet-stream"

多服务器配置示例

targets:
  # Primary
  - address: "127.0.0.1:8080"
    http:
      method: "POST"
      path: "/"
      version: "1.1"
      headers:
        User-Agent: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36"
        Content-Type: "application/octet-stream"

  # Secondary
  - address: "192.168.1.100:8080"
    http:
      method: "POST"
      path: "/api"
      version: "1.1"
      headers:
        User-Agent: "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7)"
        Content-Type: "application/octet-stream"

HTTPS 协议

基础配置（IP地址）

targets:
  - address: "127.0.0.1:443"
    http:
      method: "POST"
      path: "/"
      version: "1.1"
      headers:
        User-Agent: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36"
        Content-Type: "application/octet-stream"
    tls:
      enable: true
      sni: "127.0.0.1"
      skip_verification: true

域名配置

targets:
  - address: "primary.example.com:443"
    http:
      method: "POST"
      path: "/"
      version: "1.1"
      headers:
        User-Agent: "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7)"
        Content-Type: "application/octet-stream"
    tls:
      enable: true
      sni: "primary.example.com"
      skip_verification: true

多服务器配置示例

targets:
  # Primary
  - address: "primary.example.com:443"
    http:
      method: "POST"
      path: "/"
      version: "1.1"
      headers:
        User-Agent: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36"
        Content-Type: "application/octet-stream"
    tls:
      enable: true
      skip_verification: true

  # Secondary
  - address: "secondary.example.com:443"
    http:
      method: "POST"
      path: "/"
      version: "1.1"
      headers:
        User-Agent: "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7)"
        Content-Type: "application/octet-stream"
    tls:
      enable: true
      sni: "secondary.example.com"
      skip_verification: true

配置说明: - tls.enable: 启用TLS加密 - tls.sni: 使用域名时建议配置SNI - tls.skip_verification: 跳过证书验证

TCP 协议

基础配置

targets:
  - address: "127.0.0.1:5001"
    tcp: {}

多服务器配置示例

targets:
  # Primary
  - address: "primary.example.com:5001"
    tcp: {}

  # Secondary
  - address: "secondary.example.com:5001"
    tcp: {}

配置说明: - 最简单的配置方式，仅需指定地址 - 支持IP地址和域名 - 无加密传输，适用于内网环境

TCP+TLS 协议

基础配置

targets:
  - address: "primary.example.com:5001"
    tcp: {}
    tls:
      enable: true
      sni: "primary.example.com"
      skip_verification: true

多服务器配置示例

targets:
  # Primary
  - address: "primary.example.com:5001"
    tcp: {}
    tls:
      enable: true
      sni: "primary.example.com"
      skip_verification: true

  # Secondary
  - address: "secondary.example.com:5001"
    tcp: {}
    tls:
      enable: true
      sni: "secondary.example.com"
      skip_verification: true

补充说明

连接顺序

服务器按照在targets数组中的顺序依次尝试连接。

自动切换

当当前服务器连接失败时会继续重试连接，超过一定次数后会自动切换到下一个可用服务器。

协议限制

同一配置文件中只能使用一种通信协议（HTTP、TCP或REM），不能混用。

DGA模式配置

DGA（Domain Generation Algorithm）模式允许在默认服务器无法连接时，动态生成新的域名进行连接尝试。

配置示例

targets:
  - address: "primary.example.com:443"
    domain_suffix: "example.com"  # DGA域名后缀
    http:
      method: "POST"
      path: "/"
      version: "1.1"
      headers:
        User-Agent: "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7)"
        Content-Type: "application/octet-stream"
    tls:
      enable: true
      sni: "primary.example.com"
      skip_verification: true
