java 模拟发送post请求测试

方法一: HttpClient

1public void postTest(HttpServletRequest request,Integer type,String phone,String passwd,String schoolld,String agent){
2        String url = "xxxxxxxxx";//发送请求的URL地址 
3        JSONObject jsonObject = new JSONObject();//封装参数
4        jsonObject.put("phone", "xxxx");
5        jsonObject.put("agent", "xxxx");
6        String params=jsonObject.toString();
7        sendPostHttpClient(url, params);
8}    
9        
10        
11public String sendPostHttpClient(String url, String data) {
12        String response = null;
13        try {
14            CloseableHttpClient httpclient = null;
15            CloseableHttpResponse httpresponse = null;
16            try {
17                httpclient = HttpClients.createDefault();
18                HttpPost httppost = new HttpPost(url);
19                //StringEntity stringentity = new StringEntity(data, ContentType.create("text/json", "UTF-8"));参数传递文本格式
20                StringEntity stringentity = new StringEntity(data, ContentType.create("application/json", "UTF-8"));//参数传递json格式
21                httppost.setEntity(stringentity);
22                httpresponse = httpclient.execute(httppost);
23                response = EntityUtils.toString(httpresponse.getEntity());
24                logger.info("response: " + response);
25            } finally {
26                if (httpclient != null) {
27                    httpclient.close();
28                }
29                if (httpresponse != null) {
30                    httpresponse.close();
31                }
32            }
33        } catch (Exception e) {
34            e.printStackTrace();
35        }
36        return response;
37}

方法二：RestTemplate

1public Map<String,String> getShangHaiCarDealCount(String formatTime) {
2        Map<String,String> map=new HashMap<>();
3        map.put("flag", "fail");
4        String cycle = "1";
5        String pic_type = "3";
6        String qsrq = formatTime;
7        String Submit = "显示";
8        String zzrq = formatTime;
9        
10        String result = null;
11        try {
12            String url = "http://xxxxxxxxxxxxxxxxxxxxxx";
13            RestTemplate client = new RestTemplate();
14            HttpHeaders headers = new HttpHeaders();
15            //  请勿轻易改变此提交方式，大部分的情况下，提交方式都是表单提交
16            headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
17            //  封装参数，千万不要替换为Map与HashMap，否则参数无法传递
18            MultiValueMap<String, String> params= new LinkedMultiValueMap<String, String>();
19            //  也支持中文
20            params.add("cycle", cycle);
21            params.add("pic_type", pic_type);
22            params.add("qsrq", qsrq);
23            params.add("Submit", Submit);
24            params.add("zzrq", zzrq);
25            HttpEntity<MultiValueMap<String, String>> requestEntity = new HttpEntity<MultiValueMap<String, String>>(params, headers);
26            //  执行HTTP请求
27            ResponseEntity<String> response = client.exchange(url, HttpMethod.POST, requestEntity, String.class);
28            result = response.getBody();
29            map.put("result", result);
30            map.put("flag", "success");
31        } catch (Exception e) {
32            e.printStackTrace();
33        }
34        return map;
35    }
