连接那个IP 出口就是那个 IP

nginx打印IP方法

location /myip {
    default_type text/plain;
    return 200 "$remote_addr\n";
}

验证脚本

#!/bin/bash
TARGET_URL="验证地址/ip"  # 建议加 https
while read -r proxy; do
    # 使用 curl 测试代理，获取返回 IP
    result=$(curl -s -x "http://$proxy:8080" --connect-timeout 3 --max-time 5 "$TARGET_URL")
    if [ "$result" = "$proxy" ]; then
        echo "$result ✅"
    else
        echo "$proxy ❌ ($result)"
    fi
done

方法bash shell.sh <ip_list.txt

随机ip方案,需要oepnresty+lua来支持

access_by_lua_block {
    local ips = {
        "192.168.1.10",
        "192.168.1.11",
        "192.168.1.12",
        ...
    }

    local ip = ips[math.random(#ips)]
    ngx.var.local_bind_ip = ip
}


proxy_bind $local_bind_ip;
