JAVA利用HttpClient进行HTTPS接口调用的方法

JAVA利用HttpClient进行HTTPS接口调用的方法

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

* @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 authTyhttp://pe) 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

* @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");

}
