java https单向认证（忽略认证）并支持http基本认证

  
  https单向认证（忽略认证）并支持http基本认证，

　温馨提示 1，jar包要导入对
　　　　　 2，有匿名类编译要注意
　　　　　 3，欢迎提问，拿走不谢！

背景知识

Https访问的相关知识中，主要分为单向验证和双向验证，双向验证在单向验证的基础上构建而成

关于单向验证，如果要细分的话，分为证书验证和普通验证（忽略验证），因为这项验证针对客户端，所以客户端有能力控制是否需要验证

Java类中带有内部类和匿名类编译的class文件命名规则
内部类的class文件命名是：主类＋$＋内部类名

匿名类的class文件命名是：主类＋$＋(1,2,3....)

HttpClient 使用方法

apache.commons.httpclient.HttpClient 已不推荐使用
org.apache.http.client.HttpClient 不推荐使用现在的版本 HttpClient httpClient=new
DefaultHttpClient(); ，建议使用最新版本 CloseableHttpClient httpclient =
* HttpClients.createDefault();

1. 创建HttpClient对象。
*
* 2. 创建请求方法的实例，并指定请求URL。如果需要发送GET请求，创建HttpGet对象；如果需要发送POST请求，创建HttpPost对象。
*
* 3. 如果需要发送请求参数，可调用HttpGet、HttpPost共同的setParams(HetpParams
* params)方法来添加请求参数；对于HttpPost对象而言，也可调用setEntity(HttpEntity
* entity)方法来设置请求参数。
*
* 4. 调用HttpClient对象的execute(HttpUriRequest
* request)发送请求，该方法返回一个HttpResponse。
*
* 5. 调用HttpResponse的getAllHeaders()、getHeaders(String
* name)等方法可获取服务器的响应头；调用HttpResponse的getEntity
* ()方法可获取HttpEntity对象，该对象包装了服务器的响应内容。程序可通过该对象获取服务器的响应内容。
*
* 6. 释放连接。无论执行方法是否成功，都必须释放连接

看来这么多，想必对今天的代码有所了解了，那就直接上代码！
