本文介绍了一个使用Java实现的HTTP客户端工具类，详细展示了如何通过Apache HttpClient库发送POST请求，并解析响应结果。同时，为了处理HTTPS请求，文章还提供了一种创建信任所有证书的SSL客户端的方法。此外，还提供了一个用于将JSON字符串转换为Map的实用函数。

import java.io.BufferedReader;

public class HttpClientUtil {

   public HttpClientUtil() {
   }

   public String doPost(String var1, JSONObject var2) {
   SSLClient var3 = null;
   HttpPost var4 = null;
   String var5 = "";

   try {
   var3 = new SSLClient();
   var4 = new HttpPost(var1);
   var3.getParams().setParameter("http.protocol.content-charset", "UTF-8");
   var4.addHeader("Content-Type", "application/json");
   StringEntity var6 = new StringEntity(var2.toString(), "utf-8");
   var6.setContentType("text/json");
   var6.setContentEncoding(new BasicHeader("Content-Type", "application/json"));
   System.out.println(var2.toString());
   var4.setEntity(var6);
   HttpResponse var7 = var3.execute(var4);
   InputStream var8 = var7.getEntity().getContent();
   BufferedReader var9 = new BufferedReader(new InputStreamReader(var8, "utf-8"));
   StringBuilder var10 = new StringBuilder();
   String var11 = null;

   while((var11 = var9.readLine()) != null) {
   var10.append(var11 + "\n");
   }

   var8.close();
   var5 = var10.toString();
   System.out.println("请求结果=" + var5);
   if (var7.getStatusLine().getStatusCode() == 200) {
   System.out.println("请求服务器成功，做相应处理");
   } else {
   System.out.println("请求服务端失败");
   }

   return var5;
   } catch (Exception var12) {
   System.out.println("请求异常");
   var12.printStackTrace();
   throw new RuntimeException(var12);
   }
   }

   public static Map<String, Object> jsopStr2Map(String var0) {
   new HashMap();
   JSONObject var2 = JSONObject.fromObject(var0);
   return var2;
