android httpClient 支持HTTPS的2种处理方式

问题：

项目中Android https或http请求地址重定向为HTTPS的地址，相信很多人都遇到了这个异常(无终端认证)：

javax.net.ssl.SSLPeerUnverifiedException: No peer certificate

解决过程：

1.没遇到过的问题，搜索吧，少年

log里出现这个异常，作者第一次遇到，不知道啥意思。看下字面意思，是ssl协议中没有终端认证。SSL?作者没用到ssl协议呀，只是通过httpClient请求一个重定向https的地址。

好吧，google下，知道了个差不多情况的帖子，http://www.eoeandroid.com/thread-161747-1-1.html。恩恩，一个不错的帖子，给出了个解决方案。照着来试下。添加个继承SSLSocketFactory的

自定义类。并在初始化httpclient支持https时，注册进去。看下面代码：

ok，run下，狂乱的点到测试按钮，深吸口气，盯着eclipse中的logat。咦？神奇的竟然没有报之前的 javax.net.ssl.SSLPeerUnverifiedException: No peer certificate的异常了。服务端的数据正常返回了。,狂喜中…

2.了解并分析问题

狂喜中，得分析这问题诶。不然老大来问，啥情况？楞半天不知道咋说（作者就经常这样，所以吸取教训。所以的弄懂出现的问题，学习+汇报工作）。

思来想去，就是作者请求的是一个重定向https的地址。好吧，那就学习下https（之前被老大深深的教过，http就是request/response）。继续搜索吧，少年。下面总结下学习到的https知识。

2.1 https

HTTPS:超文本安全传输协议，和HTTP相比，多了一个SSL/TSL的认证过程，端口为443。（鄙视下之前说的)

作者没用到ssl协议呀，只是通过httpClient请求一个重定向https的地址

1.peer终端发送一个request，https服务端把支持的加密算法等以证书的形式返回一个身份信息（包含ca颁发机构和加密公钥等）。

2.获取证书之后，验证证书合法性。

3.随机产生一个密钥，并以证书当中的公钥加密。

4.request https服务端，把用公钥加密过的密钥传送给https服务端。

5.https服务端用自己的密钥解密，获取随机值。

6.之后双方传送数据都用此密钥加密后通信。

看下面一张网上的得来的https的时序图：

2.2分析下出现问题的原因

好吧，大概的流程知道了。定位已经非常清楚了。在第2步验证证书时，无法验证。为啥无法验证呢？没有添加信任。详细参考下

http://www.cnblogs.com/P_Chou/archive/2010/12/27/https-ssl-certification.html讲的非常清楚https-ssl的认证过程，膜拜下该作者

这样想来，上面提供的解决方案就是添加默认信任全部证书。以此来通过接下来的通信。

3.解决问题

但是，这样问题是解决了。但是觉得还是不带靠谱（信任全部证书有点危险）。继续噼噼啪啪的网上搜索一番。又找到了一种解决方案，其过程大致这样的：

1.浏览器访问https地址，保存提示的证书到本地，放到android项目中的assets目录。

2.导入证书，代码如下。

3.把证书添加为信任。
