Spring boot 集成 okhttp3， 使用 http，https 在項目調(diào)用第三方服務(wù)是在所難免的，運用傳統(tǒng)類型的Http調(diào)用，封裝繁瑣，代碼量多還不簡潔，避免一次一次的 找 度娘， 小記一下。

引入jar

使用 OkHttp

ok:
  # 啟用okHttp
  enable: true
  proxy:
    enable: false     # true 將啟用代理
    host: 192.168.1.1 # 代理服務(wù)器地址
    port: 8888        # 代理服務(wù)器端口
  http:
    connect-timeout: 10         # 三次握手 + SSL建立耗時 10s
    read-timeout: 5             # 連接建立后，從遠端獲取數(shù)據(jù)，TCP 傳輸 5s
    write-timeout: 5            # 連接建立后，向遠端發(fā)送數(shù)據(jù)，TCP 傳輸 5s
    call-timeout: 20            # 從發(fā)起到結(jié)束的總時長，其中不包括 UnknowsHostException 情況 30s
    max-idle-connections: 50    # 連接池中整體的空閑連接最大數(shù)量
    keep-alive-duration: 50     # 連接空閑時間最多為 50s
