@get:JvmName("minWebSocketMessageToCompress")dispatcher 用于线程调度
connectionPool 连接池 64 个or 5 host 可以提升复用性 方便管理和提升性能
interceptors
networkInterceptors
eventListenerFactory 事件监听器 连接建立 发送head body 等
retryOnConnectionFailure 连接 / 请求 失败是否重置
authenticator 自动认证修正 比如 401 无权限访问等 可以用于刷新token
followRedirects 是否继续重定向 文章来源：https://www.toymoban.com/news/detail-661161.html
followSslRedirects 在followRedirects 开启时 协议切换时 是否继续重定向 比如http 切换https 默认true 文章来源地址https://www.toymoban.com/news/detail-661161.html
cookieJar 存储器 存储cookie 默认是空实现
cache 本地缓存
dns 域名系统 域名解析为ip 函数为 lookup getAllByName List inntAddress 通过域名返回IPList---InetAddress.getAllByName(hostName)
proxy 代理 转发 代理服务器 代理多种方式 还有反向代理 类型 DIRECT 直连 HTTP SOCKS,默认NO_PROXY
proxySelector 判断是否代理 通过select 方法 返回List<Proxy>
proxyAuthenticator 如果代理不可用 需要授权 需要验证机制
socketFactory http请求本质是java socket 通过socketFactory 创建
sslSocketFactory ssl 请求, tls ssl 加密 连接
x509TrustManager 证书验证器,通过证书和签名进行验证 ,X509 证书格式
connectionSpecs List 连接标准 规范,https 连接 客户端 发送tls 连接 的规范 比如连接套件 非对称加密等,ConnectionSpec 类定义各种规范比如 RESTRICTED_TLS支持TLS 1.3 1.2 ,MODERN_TLS1.3 1.2 ,COMPATIBLE_TLS 支持 1.3 1.2 1.1 1.0,CLEARTEXT 明文 传输https 报文 不用tls
protocols List, 支持协力的版本号 比如 1.0 , 1.1, SPDY2,SPDY3 ,HTTP2 最好使用加密 h2c ,H2_PRIOR 非加密,
hostnameVerifier: 验证合法性 域名 只验证第一个 [0]
certificatePinner:加强验证,可以配置证书 hash
certificateChainCleaner:=== 证书验证相关 操作X509
callTimeoutMillis 超时
connectTimeoutMillis 连接超时
readTimeoutMillis 读取超时
writeTimeoutMillis 写入超时
pingIntervalMillis 心跳机制 websocket / http2 使用
