HttpClient测试题库API数据接口

创建响应格式类

@Data
@NoArgsConstructor
@AllArgsConstructor
public class HttpResult {

private int code;

private String body;

}

创建一个HttpClient工具类

public class HttpClientUtil {

private CloseableHttpClient httpClient;

public HttpClientUtil() {
    // 1 创建HttpClinet，相当于打开浏览器
    httpClient = HttpClients.createDefault();
}

}

创建GET请求方法

public HttpResult doGet(String url, Map<String, String> SignMap,String token, Map<String, String> map) throws Exception {

    // 声明URIBuilder
    URIBuilder uriBuilder = new URIBuilder(url);


    // 判断参数map是否为非空
    if (map != null) {
        // 遍历参数
        for (Map.Entry<String, String> entry : map.entrySet()) {
            // 设置参数  将需要的参数添加到url
            uriBuilder.setParameter(entry.getKey(), entry.getValue().toString());
        }
    }

    // 2 创建httpGet对象，相当于设置url请求地址
    HttpGet httpGet = new HttpGet(uriBuilder.build());


	//获取签名
    //将业务参数构建成map后传入，得到nonce ,accesskey,timestamp,sign  请求头参数map
    Map<String, String> map1 = SignUtil.buildSignParam (SignMap, Constant.clientId, Constant.clientSecret , 10 ,"GET");

    //遍历存值
    for(Map.Entry<String, String> entry : map1.entrySet()) {

        httpGet.addHeader(entry.getKey(),entry.getValue());

    }

    //Authorization令牌
    httpGet.addHeader("Authorization", "Bearer" + " " + token);

    //Content-Type 数据结构
    httpGet.addHeader("Content-Type", "application/json");

    // 3 使用HttpClient执行httpGet，相当于按回车，发起请求
    CloseableHttpResponse response = null;
    try {
        response = httpClient.execute(httpGet);
    } catch (IOException e) {
        HttpResult httpResult = new HttpResult();
        httpResult.setCode(404);
        httpResult.setBody("请求失败");
        return httpResult;
    }

    // 4 解析结果，封装返回对象httpResult，相当于显示相应的结果
    // 状态码
    // response.getStatusLine().getStatusCode();
    // 响应体，字符串，如果response.getEntity()为空，下面这个代码会报错,所以解析之前要做非空的判断
    // EntityUtils.toString(response.getEntity(), "UTF-8");

    HttpResult httpResult = new HttpResult();
    // 解析数据封装HttpResult

    if (response.getEntity() != null) {
        //httpResult = new HttpResult(response.getStatusLine().getStatusCode(),EntityUtils.toString(response.getEntity(),"UTF-8"));
        httpResult.setCode(response.getStatusLine().getStatusCode());
        httpResult.setBody(EntityUtils.toString(response.getEntity(),"UTF-8"));

    } else {
        //httpResult = new HttpResult(response.getStatusLine().getStatusCode(), "");
        httpResult.setCode(response.getStatusLine().getStatusCode());
        //httpResult.setBody("");
    }

    System.out.println(httpResult.getBody());
    // 返回
    return httpResult;
}

因为这边调用的是题库的API接口，需要有相应的开发者id来生成需要的签名

创建POST方法

public HttpResult doPost(String url, String SignJson, String token, String jsonObj ) throws Exception {
    // 声明httpPost请求
    HttpPost httpPost = new HttpPost(url);

    // 判断map不为空
    if (jsonObj != null) {

		//传入json字符串类型的参数
		//map类型使用 formEntity
        StringEntity stringEntity = new StringEntity(jsonObj,"UTF-8");

        // 把表单对象设置到httpPost中
        httpPost.setEntity(stringEntity);

        System.out.println(stringEntity);

    }


    //将业务参数构建成map后传入，得到nonce ,accesskey,timestamp,sign  请求头参数map
    Map<String, String> Headmap = SignUtil.buildSignParam (SignJson, Constant.clientId, Constant.clientSecret , 10 ,"POST");

    //遍历存值
    for(Map.Entry<String, String> entry : Headmap.entrySet()) {

        httpPost.addHeader(entry.getKey(),entry.getValue());

    }

    //Authorization令牌
    httpPost.addHeader("Authorization", "Bearer" + " " + token );

    //Content-Type 数据结构
    httpPost.addHeader("Content-Type", "application/json");


    // 使用HttpClient发起请求，返回response
    CloseableHttpResponse response = null;
    try {
        response = httpClient.execute(httpPost);
    } catch (IOException e) {
        HttpResult httpResult = new HttpResult();
        httpResult.setCode(404);
        httpResult.setBody("请求失败");
        return httpResult;
    }

    // 解析response封装返回对象httpResult
    HttpResult httpResult = new HttpResult();
    // 解析数据封装HttpResult
    if (response.getEntity() != null) {
        //httpResult = new HttpResult(response.getStatusLine().getStatusCode(),EntityUtils.toString(response.getEntity(),"UTF-8"));
        httpResult.setCode(response.getStatusLine().getStatusCode());
        httpResult.setBody(EntityUtils.toString(response.getEntity(),"UTF-8"));

    } else {
        //httpResult = new HttpResult(response.getStatusLine().getStatusCode(), "");
        httpResult.setCode(response.getStatusLine().getStatusCode());
        httpResult.setBody("");
    }

    System.out.println(httpResult.getBody());

    // 返回结果
    return httpResult;
}

编写测试GetDemo

		HttpClientUtil clientUtil = new HttpClientUtil();

//      GET 查询学科接口
 	    String geturl = "http://api.jtyedu.com/v1/api/subjects";
         Map<String, String> temp = new HashMap<>();
//       添加学段参数
 	    temp.put("stageId", "2");
 	    //获取token
        String token = getToken();
        clientUtil.doGet(geturl,temp,token,temp);
 	    输出结果
{"code":1,"msg":"成功","data":[{"id":1,"name":"语文"},{"id":2,"name":"数学"},{"id":3,"name":"英语"},{"id":4,"name":"道德与法治"},{"id":5,"name":"科学"},{"id":6,"name":"信息技术"},{"id":7,"name":"音乐"},{"id":8,"name":"美术"}]}

编写测试PostDemo

        HttpClientUtil clientUtil = new HttpClientUtil();
        
        String url = "http://api.jtyedu.com/v1/api/question/ids";
        
   		 JSONObject jsonObject = new JSONObject();
        jsonObject.put("questionIds", "1");
	    jsonObject.put("textbookId", "1");
 	    String JsonString = jsonObject.toString();
 	    
 	    clientUtil.doPost(url,JsonString,token,JsonString);
 	    输出结果
 	    {"code":1,"msg":"成功","data":[]}
