Web支持HTTPS的client(HTTP&XML-RPC)
生成Web自签名的证书（在命令行执行以下命令）
keytool -genkey -keysize 2048 -validity 3650 -keyalg RSA -dname "CN=Hanshow, OU=Hanshow, O=Hanshow, L=Jiaxing, ST=Zhejiang, C=CN" -alias shopweb -keypass password_of_key -storepass password_of_store -keystore shopweb.jks
-keysize 2048 指定生成2048位的密钥
-validity 3650 指定证书有效期天数（3650=10年）
-keyalg RSA 指定用RSA算法生成密钥
-dname 设置签发者的信息
-alias 设置别名
-keypass 设定访问key的password
-storepass 设定访问这个KeyStore的password
web.jks指定生成的KeyStore文件名叫web.jks
- 把生成的web.jks存放到classpath路径中。
- 以下代码依赖Jackson JSON，OkHttp3，Apache XML-RPC Client。
- 以下的实现全部是基于trustAll，即信任任何服务器
