java模拟多线程http请求代码分享
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：
packagetest;
importjava.util.ArrayList;
importjava.util.HashMap;
importjava.util.List;
importjava.util.Map;
importjava.util.Map.Entry;
importjava.util.concurrent.ExecutorService;
importjava.util.concurrent.Executors;
importorg.apache.http.HttpEntity;
importorg.apache.http.NameValuePair;
importorg.apache.http.client.config.RequestConfig;
importorg.apache.http.client.entity.UrlEncodedFormEntity;
importorg.apache.http.client.methods.CloseableHttpResponse;
importorg.apache.http.client.methods.HttpPost;
importorg.apache.http.impl.client.CloseableHttpClient;
importorg.apache.http.impl.client.HttpClients;
importorg.apache.http.message.BasicNameValuePair;
importorg.apache.http.util.EntityUtils;

returnparams;
}
publicstaticvoidmain(String[]args){
//运用java工具类中线程池
ExecutorServicepool=Executors.newCachedThreadPool();
for(inti=0;i<2;i++){//开启俩个线程

}
}
publicstaticMapgetHttpParamStr(){

param.put("apiversion",1);
param.put("appversion","3.6.2");
returnparam;
}
}
