[开发测试]Post路径请求参数在java体中实现方式

Post路径请求参数在java体中实现方式

1. 使用Map进行参数的封装

	Map<String, Object> map = new HashMap<>(4);
        map.put("param1", param1);
        map.put("param2", param2);
        map.put("param3", param3);
        ...
      //根据实际业务需求放入参数

2. 发送请求

   try{
            post = this.post(url, map);
            jsonObject = JSONObject.parseObject(post);
            errcode = (String) jsonObject.get("errcode");
            if(StringUtils.isNotEmpty(errcode)) {
               //此处可以进行业务的异常情况处理
            }
            // 得到响应参数
        }catch (Exception e){
            log.error(""+e);
  			//打印异常信息
        }

3. post方法实现

public static String post(String uri, Map<String, Object> params) {
        CloseableHttpClient httpclient = HttpClients.createDefault();
        HttpPost httpPost = new HttpPost(uri);
        CloseableHttpResponse response = null;
        try {

            List<BasicNameValuePair> parameters = Lists.newArrayList();

            Set<Map.Entry<String, Object>> enties = params.entrySet();
            for(Map.Entry<String, Object> entry : enties) {
                parameters.add(new BasicNameValuePair(entry.getKey(), entry.getValue().toString()));
            }

            UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(parameters, "utf-8");
            httpPost.setEntity(formEntity);

            response = httpclient.execute(httpPost);

            if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
                HttpEntity httpEntity = response.getEntity();
                String result = null;
                result = EntityUtils.toString(httpEntity);
                return result;
            }

        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                if (httpclient != null) {
                    httpclient.close();
                    httpclient = null;
                }
                if (httpPost != null) {
                    httpPost.releaseConnection();
                    httpPost = null;
                }
                if (response != null) {
                    response.close();
                    response = null;
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return null;
    }
