    "timeout":300,                  # 时间，默认就好
    "method":"aes-256-cfb",         # 加密方式，默认就好

{
    "server": "0.0.0.0",
    "port_password": {
        "8388": "123456789",
        "8381": "123456789",
        "8382": "123456789",
        "8383": "123456789"
    },
    "local_address": "127.0.0.1",
    "local_port":1080,
    "timeout": 300,
