/**
* @see =====================================================================================================
* @see 在开发HTTPS应用时，时常会遇到两种情况
* @see 1、要么测试服务器没有有效的SSL证书,客户端连接时就会抛异常
* @see javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated
* @see 2、要么测试服务器有SSL证书,但可能由于各种不知名的原因,它还是会抛一个堆烂码七糟的异常
* @see =====================================================================================================
* @see 由于我们这里使用的是HttpComponents-Client-4.1.2创建的连接，所以，我们就要告诉它使用一个不同的TrustManager
* @see TrustManager是一个用于检查给定的证书是否有效的类
* @see SSL使用的模式是X.509....对于该模式,Java有一个特定的TrustManager,称为X509TrustManager
* @see 所以我们自己创建一个X509TrustManager实例
* @see 而在X509TrustManager实例中，若证书无效，那么TrustManager在它的checkXXX()方法中将抛出CertificateException
* @see 既然我们要接受所有的证书,那么X509TrustManager里面的方法体中不抛出异常就行了
* @see 然后创建一个SSLContext并使用X509TrustManager实例来初始化之
* @see 接着通过SSLContext创建SSLSocketFactory，最后将SSLSocketFactory注册给HttpClient就可以了
