Java测试开发--HttpClient常规用法(九)
1.HttpClient可以读取网页(HTTP/HTTPS)内容
2.对url发送get/post请求(带不带参数都可以),进行测试
一、maven项目pom.xml需要引入包
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5.13</version>
</dependency>
二、新建类进行测试
1 public class HttpClientTest { 2 3 public static void main(String[] args) throws IOException{ 4 //创建默认http请求 5 HttpClient httpClient = HttpClients.createDefault(); 6 //创建post请求 7 HttpPost httpPost = new HttpPost("http://127.0.1.1:8080/goods/UserServlet"); 8 //传递参数 9 List<NameValuePair> pairsList = new ArrayList<NameValuePair>(); 10 11 BasicNameValuePair bPair1 = new BasicNameValuePair("method", "loginMobile"); 12 BasicNameValuePair bPair2 = new BasicNameValuePair("loginname", "abc"); 13 BasicNameValuePair bPair3 = new BasicNameValuePair("password", "abc"); 14 pairsList.add(bPair1); 15 pairsList.add(bPair2); 16 pairsList.add(bPair3); 17 HttpEntity httpEntity = null; 18 try { 19 //参数转码 20 httpEntity = new UrlEncodedFormEntity(pairsList,"utf-8"); 21 //请求实体放入post请求中 22 httpPost.setEntity(httpEntity); 23 //用http连接执行post请求并且获得http请求响应 24 HttpResponse response = httpClient.execute(httpPost); 25 //从response中取到响应实体 26 HttpEntity entity = response.getEntity(); 27 //把响应实体转到文本 28 String html = EntityUtils.toString(entity); 29 System.out.println("====="+html); 30 } catch (UnsupportedEncodingException e) { 31 // TODO Auto-generated catch block 32 e.printStackTrace(); 33 } 34 } 35 36 }
