本文介绍了一种绕过HTTPS证书验证的方法，并演示了如何使用Apache HttpClient库发送POST请求。通过创建自定义的SSLClient类，我们实现了对证书验证的忽略，确保了即使在证书不可信的情况下也能成功发起请求。此外，还提供了一个测试类，用于展示如何使用这些工具进行实际的POST请求。

1.绕过证书验证

import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import org.apache.http.conn.ClientConnectionManager;
import org.apache.http.conn.scheme.Scheme;
import org.apache.http.conn.scheme.SchemeRegistry;
import org.apache.http.conn.ssl.SSLSocketFactory;
import org.apache.http.impl.client.DefaultHttpClient;
//用于进行Https请求的HttpClient
public class SSLClient extends DefaultHttpClient{
	public SSLClient() throws Exception{
        super();
        SSLContext ctx = SSLContext.getInstance("TLS");
        X509TrustManager tm = new X509TrustManager() {
                @Override
                public void checkClientTrusted(X509Certificate[] chain,
                        String authType) throws CertificateException {
                }
                @Override
                public void checkServerTrusted(X509Certificate[] chain,
                        String authType) throws CertificateException {
                }
                @Override
                public X509Certificate[] getAcceptedIssuers() {
                    return null;
                }
        };
        ctx.init(null, new TrustManager[]{tm}, null);
        SSLSocketFactory ssf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
        ClientConnectionManager ccm = this.getConnectionManager();
        SchemeRegistry sr = ccm.getSchemeRegistry();
        sr.register(new Scheme("https", 443, ssf));
    }
}

　　2.实现httpclient客户端发送post请求报文

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import java.util.Map.Entry;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.message.BasicHeader;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.util.EntityUtils;
/*
 * 利用HttpClient进行post请求的工具类
 */
public class HttpClientUtil {
	public String doPost(String url,Map<String,Object> map,String charset){
		HttpClient httpClient = null;
		HttpPost httpPost = null;
		String result = null;
		try{
			httpClient = new SSLClient();
			httpPost = new HttpPost(url);
			//设置参数
			List<NameValuePair> list = new ArrayList<NameValuePair>();
			Iterator iterator = map.entrySet().iterator();
			while(iterator.hasNext()){
				Entry<String,Object> elem = (Entry<String, Object>) iterator.next();
				list.add(new BasicNameValuePair(elem.getKey(),(String) elem.getValue()));
			}
			if(list.size() > 0){
				UrlEncodedFormEntity entity = new UrlEncodedFormEntity(list,charset);
				httpPost.setEntity(entity);
			}
			HttpResponse response = httpClient.execute(httpPost);
			if(response != null){
				HttpEntity resEntity = response.getEntity();
				if(resEntity != null){
					result = EntityUtils.toString(resEntity,charset);
				}
			}
		}catch(Exception ex){
			ex.printStackTrace();
		}
		return result;
	}
    public static String doPost(String url,String json){
        HttpClient httpClient = null;
        HttpPost httpPost = null;
        String result = null;
        try{
            httpClient = new SSLClient();
            httpPost = new HttpPost(url);
            httpPost.addHeader("Content-Type", "application/json");
            StringEntity se = new StringEntity(json);
            se.setContentType("text/json");
            se.setContentEncoding(new BasicHeader("Content-Type", "application/json"));
            httpPost.setEntity(se);
            HttpResponse response = httpClient.execute(httpPost);
            if(response != null){
                HttpEntity resEntity = response.getEntity();
                if(resEntity != null){
                    result = EntityUtils.toString(resEntity,"utf-8");
                }
            }
        }catch(Exception ex){
            ex.printStackTrace();
        }
        return result;
    }
}

　　3.测试类

import java.util.HashMap;
import java.util.Map;

import com.alibaba.fastjson.JSONObject;
//对接口进行测试
public class TestMain {
	private String url = "https://www.baidu.com/aa/api/cc";
	private String charset = "utf-8";
	private HttpClientUtil httpClientUtil = null;
	
	public TestMain(){
		httpClientUtil = new HttpClientUtil();
	}      
	
	public void test(){
		String httpOrgCreateTest = url;
		
		String json = "{\r\n" + 
				"	\"SessionId\":\"9977uqut\",\r\n" + 
				"	\"Caller\":\"86675251\",\r\n" + 
				"	\"Called\":\"18258268539\",\r\n" + 
				"	\"DisplayNumber\":\"18258268539\",\r\n" + 
				"	\"MediaAddress\":\"10.8.22.16\",\r\n" + 
				"	\"MediaPort\":10,\r\n" + 
				"	\"PayloadType\":8,\r\n" + 
				"	\"PacketTime\":20,\r\n" + 
				"	\"MediaAttribute\":1,\r\n" + 
				"	\"BitRate\":1,\r\n" + 
				"	\"SampleRate\":8000,\r\n" + 
				"	\"CSRId\":\"teller09\"\r\n" + 
				"}";
		String httpOrgCreateTestRtn = httpClientUtil.doPost(httpOrgCreateTest,json);
		System.out.println("result:"+httpOrgCreateTestRtn);
	}
	
	public static void main(String[] args){
		TestMain main = new TestMain();
		main.test();
	}
}
