Http和Https网络同步请求httpclient和异步请求async-http-client

Http和https网络请求

主要总结一下使用到的网络请求框架，一种是同步网络请求org.apache.httpcomponents的httpclient，另一种是异步网络请求com.ning的async-http-client，总结一下常用的http请求方式封装使用，如post、get、put、delete等，以及涉及到ssl证书https请求的双向证书验证。

一、apache同步请求httpclient

1、引入文件

[java] view plain copy

<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5.2</version>
</dependency>

2、http和https的方法封装

涉及常用的post和get的请求，https的ssl双向证书验证。
