java模拟post请求

一般API接收客户端（比如网页、APP或其他应用服务）的请求，但在测试时需要模拟来自外界的请求，经探索，使用HttpComponentshttpClient可模拟Post提交请求。

此处用HttpComponents的httpclient来完成使命。

import org.apache.http.HttpEntity ;
import org.apache.http.HttpResponse ;
import org.apache.http.client.HttpClient ;
import org.apache.http.client.methods.HttpPost ;
import org.apache.http.impl.client.DefaultHttpClient ;
import org.apache.http.util.EntityUtils ;
import org.junit.Test ;

import java.io.IOException ;

    @Test 
    public void testPost () throws IOException {
        HttpClient client = new DefaultHttpClient() ;
        HttpPost post = new HttpPost("http://127.0.0.1:8080/app/index" ) ;
        post.setHeader( "storeId" ,"1456" ) ;
        post.setHeader( "platform" , "IOS" ) ;
        post.setHeader( "device" , "Iphone6 plus" ) ;
        post.setHeader( "venderId" , "5" ) ;
        HttpResponse response = client.execute(post) ;

        if (response.getStatusLine().getStatusCode() == 200 ) {
            HttpEntity resEntity = response.getEntity() ;
            String message = EntityUtils. toString(resEntity , "utf-8") ;
            System. out .println(message); 
        } else {
            System. out.println(response.getStatusLine().getStatusCode()) ;
            System. out .println("请求失败" ) ;
        } 
    }
