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

public class HttpClientTest {
    
    public static void main(String[] args) throws IOException{
        //创建默认http请求
        HttpClient  httpClient = HttpClients.createDefault();
        //创建post请求
        HttpPost  httpPost = new HttpPost("http://127.0.1.1:8080/goods/UserServlet");
        //传递参数
        List<NameValuePair> pairsList = new ArrayList<NameValuePair>();
        
        BasicNameValuePair bPair1 = new BasicNameValuePair("method", "loginMobile");
        BasicNameValuePair bPair2 = new BasicNameValuePair("loginname", "abc");
        BasicNameValuePair bPair3 = new BasicNameValuePair("password", "abc");
        pairsList.add(bPair1);
        pairsList.add(bPair2);
        pairsList.add(bPair3);
        HttpEntity httpEntity = null;
        try {
            //参数转码
            httpEntity = new UrlEncodedFormEntity(pairsList,"utf-8");
            //请求实体放入post请求中
            httpPost.setEntity(httpEntity);
            //用http连接执行post请求并且获得http请求响应
            HttpResponse response = httpClient.execute(httpPost);
            //从response中取到响应实体
            HttpEntity entity = response.getEntity();
            //把响应实体转到文本
            String  html = EntityUtils.toString(entity);
            System.out.println("====="+html);
        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

}
