JAVA利用HttpClient进行HTTPS接口调用的方法

2019年07月19日 | 移动技术网IT编程 | 我要评论

本文介绍了java利用httpclient进行https接口调用的方法，分享给大家，具体如下：

1.为了避免需要证书，所以用一个类继承defaulthttpclient类，忽略校验过程。

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 
 * @classname: sslclient 
 * @description: todo
 * @author devin <xxx> 
 * @date 2017年2月7日 下午1:42:07 
 * 
 */
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.创建一个利用httpclient发送post请求的工具类

import org.apache.http.httpentity;
import org.apache.http.httpresponse;
import org.apache.http.statusline;
import org.apache.http.client.httpclient;
import org.apache.http.client.methods.httppost;
import org.apache.http.entity.stringentity;
import org.apache.http.message.basicheader;
import org.apache.http.util.entityutils;
/**
 * 利用httpclient进行post请求的工具类
 * @classname: httpclientutil 
 * @description: todo
 * @author devin <xxx> 
 * @date 2017年2月7日 下午1:43:38 
 * 
 */
public class httpclientutil {
  @suppresswarnings("resource")
  public static string dopost(string url,string jsonstr,string charset){
    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(jsonstr);
      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,charset);
        }
      }
    }catch(exception ex){
      ex.printstacktrace();
    }
    return result;
  }
}

3.测试代码

public static void main(string[] args){ 
    string url = "https://192.168.1.101/xxx";
    string jsonstr = "{xxx}";
    string httporgcreatetestrtn = httpclientutil.dopost(url, jsonstr, "utf-8");
  }
