httpclient访问https

HttpClient访问https站点时，需要注意证书的处理。有几种方法可以解决这个问题。方法一是将站点的证书导入到Java的证书库文件中。方法二是在HttpClient访问时使用网站的证书进行访问。方法三是在HttpClient访问https站点时忽略认证。方法四是在HttpClient访问https站点时信任所有证书。如果JRE或者JDK没有导入某个站点的证书，那么在访问时会报错，错误信息可能是"javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"。\[1\]\[2\]\[3\]
