多次理解，反复练习，破釜沉舟。
Apache Jakarta Common 下的子项目
支持 HTTP 协议的客户端编程工具包
支持 HTTP 协议最新的版本
怎么利用HttpClient写自动化
简化重点：
1、接口请求与接口响应（先要理解http协议），常见的以下两种请求方式
Get
Post
2、数据解析，学会以下用法
JsonObject
JsonArray
3、结果断言
演示代码片段
这里以https://my.oschina.net/u/3559695/blog/1600534/网页的接口为例 1 @Test
IOException {
3 // 构造数据
4 String cookie = "111111";//会定时更新，自己去获取吧～
7 //json的写法 => Content-Type:application/json (传输的数据格式)
8 // User user=new User();//需要新建一个User类，命名属性的set方法
9 // user.setUserId(3559695);
10 // user.setSkillsNum(5);
11 // String jsonString=JSON.toJSONString(user); 等同于 String jsonString=" {\"userId\":3559695,\"skillsNum\":5}";
12 // System.out.println("打印"+jsonString);
13 // StringEntity stringEntity=new StringEntity(jsonString);
14
15 //form的写法 => Content-Type:application/x-www-form-urlencoded
16 //携带普通的参数params的方式
17 List<NameValuePair> params=new ArrayList<>();
18 params.add(new BasicNameValuePair("userId","3559695"));//BasicNameValuePair是存储键值对的类
19 params.add(new BasicNameValuePair("skillsNum","5"));
20 String jsonString=EntityUtils.toString(new UrlEncodedFormEntity(params, Consts.UTF_8));//这里就是：userId=3559695&skillsNum=5
21 System.out.println(jsonString);
22
23 //1、打开浏览器
24 CloseableHttpClient httpClient = HttpClients.createDefault();
25 //2、创建httpGet对象
26 HttpPost httpPost = new HttpPost("https://my.oschina.net/u/3559695/radar/getUserPortraitRadarMap");
27 httpPost.addHeader("Cookie", cookie);
28 // httpPost.addHeader("Accept-Encoding","gzip, deflate, br");
29 httpPost.addHeader("Content-Type", "application/x-www-form-urlencoded");
30 httpPost.addHeader("User-Agent",
31 "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.97 Safari/537.36");
32 // httpPost.setEntity(stringEntity); 这个是json格式的方式
33 httpPost.setEntity(new UrlEncodedFormEntity(params,"UTF-8"));
34 //3、发送请求，获取响应模型
35 CloseableHttpResponse httpResponse = httpClient.execute(httpPost);
36 //4、从响应模型获取响应实体
37 HttpEntity httpEntity = httpResponse.getEntity();
38 //5、将响应实体转为String
39 if (httpEntity != null){
40 String str = EntityUtils.toString(httpEntity);
41 System.out.println(str);
42 //6、String解析为JsonObject、JsonArray
43 JSONObject jsonObject=JSONObject.parseObject(str);
44 System.out.println(jsonObject);
45 System.out.println("输出状态码code："+jsonObject.getString("code"));
46 System.out.println(jsonObject.get(1));
47 JSONObject jsonObject1=jsonObject.getJSONObject("result");
48 System.out.println(jsonObject1);
49 JSONArray jsonArray=JSONArray.parseArray(jsonObject1.getString("skills"));
50 System.out.println(jsonArray);
51 System.out.println(jsonArray.get(1));
52
53 //测试
54 Assert.assertEquals(jsonObject.getString("code"),"1");
55 Assert.assertTrue(jsonArray.get(1).equals("社区影响力"));
56 Assert.assertNotNull(jsonObject.getString("result"));
57 Assert.assertNotSame(jsonObject1.getString("skills"),jsonArray);
58
59 }else EntityUtils.consume(httpEntity);
60 //释放资源
61 httpResponse.close();
62 httpClient.close();
63 }
url响应结果：
{"code":1,"message":"success","result":{"skills":["社区活跃度","社区影响力","技术贡献度","活动活跃性","开源贡献度","学习积极性"],"maxSkillScore":100,"skillsScore":[11.932739749333637,10.202996646175928,10.279304325337817,5.0,5.0,12.192893401015228]},"time":"2019-11-21 12:45:10"}
