java模拟http发送请求,第一种是HttpURLConnection发送post请求,第二种是使用httpclient模拟post请求,
实例代码:
package test; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; import java.util.Map.Entry; import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; import org.apache.http.HttpEntity; import org.apache.http.NameValuePair; import org.apache.http.client.config.RequestConfig; import org.apache.http.client.entity.UrlEncodedFormEntity; import org.apache.http.client.methods.CloseableHttpResponse; import org.apache.http.client.methods.HttpPost; import org.apache.http.impl.client.CloseableHttpClient; import org.apache.http.impl.client.HttpClients; import org.apache.http.message.BasicNameValuePair; import org.apache.http.util.EntityUtils; /**java 模拟测试多线程测试http请求 * @author wdh * */ public class ServiceThreadTest implements Runnable{ private String url; private MapparamStr; public ServiceThreadTest(String url, Map paramStr) { super(); this.url = url; this.paramStr = paramStr; } public String getUrl() { return url; } public void setUrl(String url) { this.url = url; } public Map getParamStr() { return paramStr; } public void setParamStr(Map paramStr) { this.paramStr = paramStr; } @Override public void run() { // http请求实现方式 CloseableHttpClient httpClient = HttpClients.createDefault(); HttpPost post = new HttpPost(url); RequestConfig cOnfig= RequestConfig.custom().setConnectionRequestTimeout(10000).setConnectTimeout(10000) .setSocketTimeout(10000).build(); CloseableHttpResponse respOnse= null; try { List params = setHttpNameValues(paramStr); HttpEntity httpentity=new UrlEncodedFormEntity(params,"utf-8"); post.setEntity(httpentity); post.setConfig(config); respOnse= httpClient.execute(post); HttpEntity entity = response.getEntity(); String cOntent= EntityUtils.toString(entity); System.out.println("content:" + content); } catch (Exception e) { e.printStackTrace(); } } private List setHttpNameValues(Map paramMap) { List params = new ArrayList (); for (Entry entry:paramMap.entrySet()){ params.add(new BasicNameValuePair(entry.getKey(),entry.getValue().toString())); } return params; } public static void main(String[] args) { //运用java工具类中线程池 ExecutorService pool = Executors.newCachedThreadPool(); for (int i =0;i<2;i++) { //开启俩个线程 String url = "xxxx"; Map paramStr = getHttpParamStr(); pool.execute(new ServiceThreadTest(url,paramStr)); } } public static Map getHttpParamStr() { Map param = new HashMap (); param.put("apiversion", 1); param.put("appversion", "3.6.2"); return param; } }
