java 连接https请求方法 使用httpclient_访问调用https方法

下一篇:很抱歉没有了

https请求比http更安全 是在http的基础上加了SSL数据加密协议

http的连接很简单,是无状态的;HTTPS协议是由SSL+HTTP协议构建的可进行加密传输、身份认证的网络协议,比http协议安全

下面介绍一下java 代码如何调用https请求,这里使用的是httpclient 代码如下:

import java.net.URI;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import java.util.Map.Entry;

import javax.net.ssl.SSLContext;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.client.HttpClient;
import org.apache.http.client.config.RequestConfig;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.client.utils.URIBuilder;
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.conn.ssl.SSLContextBuilder;
import org.apache.http.conn.ssl.TrustStrategy;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;


public class HttpsclientTest {


	public static void main(String[] args) {
		try {
		
		
			SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy() {
				@Override
				public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
					return true;
				}
			}).build();
			SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext);
			HttpClient httpClient = HttpClients.custom().setSSLSocketFactory(sslsf).build();
			HttpPost httppost = new HttpPost("https://community.apache.org/contributors/");
			MultipartEntityBuilder mEntityBuilder = MultipartEntityBuilder.create();
			//params
			//mEntityBuilder.addTextBody("userName", "1234");

			httppost.setEntity(mEntityBuilder.build());
			//httppost.addHeader("Content-Type", "Application/JSON");
			
			int timeOut = 1000*50;
			// set Timeout
			RequestConfig requestConfig = RequestConfig.custom().setConnectionRequestTimeout(timeOut)
					.setConnectTimeout(timeOut).setSocketTimeout(timeOut).build();
			httppost.setConfig(requestConfig);
			// get responce
			HttpResponse responce = httpClient.execute(httppost);
			// get http status code
			int status = responce.getStatusLine().getStatusCode();
			System.out.println("request code:" + status);
			String resultString = null;
			if (status == HttpStatus.SC_OK) {
				// get result data
				HttpEntity entity = responce.getEntity();
				resultString = EntityUtils.toString(entity);
			}
			System.out.println(resultString);
		
			
		}
		catch (Exception e) {
			e.printStackTrace();
		}
	
	}
