二、get方法的请求和测试

2）用户展示请求方式是: Get

3）接口的url 是: /api/users

4）接口的响应状态码是200，还可以看到响应body的JSON内容。

二、get方法的请求和测试

1.封装回去请求地址的方法

package com.automation.test;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Properties;

public class TestBase {
   public Properties props ;

   public TestBase() {
       try {
           props = new Properties();
           FileInputStream fis = new FileInputStream(System.getProperty("user.dir")+"\\src\\main\\java\\com\\qa\\config\\config.properties");
           props.load(fis);
       } catch (FileNotFoundException e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       } catch (IOException e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       }

   }
   public static void main(String[] args) {
       System.out.println(System.getProperty("user.dir")); // 这个方法就是找到项目的绝对路径的位置。
   }
}

2封装一个获取请求头的方法

package com.qa.restclient;

import java.io.IOException;
import java.util.HashMap;

import org.apache.http.Header;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;
import org.json.JSONObject;
import org.json.JSONString;

public class RestClient {


   public void get(String url) throws Exception {
       //创建一个可关闭的HttpClient对象
       CloseableHttpClient httpClient = HttpClients.createDefault();
       //创建一个HttpGet的请求对象
       HttpGet get = new HttpGet(url);
       //执行请求,相当于postman上点击发送按钮，然后赋值给HttpResponse对象接收
       CloseableHttpResponse httpResponse = httpClient.execute(get);

       //获取响应的代码
       int statusCode = httpResponse.getStatusLine().getStatusCode();
       System.out.println("获取响应的代码"+statusCode);
       //把响应的内容存在字符串中
       String responseString = EntityUtils.toString(httpResponse.getEntity(),"utf-8");
       System.out.println(responseString);
       //创建Json对象,把上面你的字符串序列化为Json对象
       JSONObject jsonObject = new JSONObject(responseString);
       System.out.println("respon json from API-->" + jsonObject);
       //获取响应头信息,返回是一个数组
        Header[] headerArray = httpResponse.getAllHeaders();
        //创建一个hashmap对象，通过postman可以看到请求响应头信息都是Key和value得形式，所以我们想起了HashMap
        HashMap<String, String> hm = new HashMap<String, String>();
        //增强for循环遍历headerArray数组，依次把元素添加到hashmap集合
        for(Header header : headerArray) {
            hm.put(header.getName(), header.getValue());
        }

        //打印hashmap
        System.out.println("response headers -->"+ hm);

   }
   public static void main(String[] args) {
       RestClient client = new RestClient();
       try {
           client.get("https://reqres.in/api/users");
       } catch (Exception e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       }
   }
}

在通过testng进行测试

package com.qa.tests;

import javax.management.MXBean;

import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

import com.automation.test.TestBase;
import com.qa.restclient.RestClient;

public class GetApiTest extends TestBase {
   private String url;
   private RestClient restclient;
   private GetApiTest apiTest;
   @BeforeClass
   public void setUp() {
       apiTest = new GetApiTest();
       url = (String) apiTest.props.get("HOST");
       System.out.println(url);

   }
   @Test
   public void test() throws Exception {
       restclient = new RestClient();
       restclient.get(url + "/api/users");
   }
}
