Java请求调用参数格式为raw_json类型的接口

**接口参数使用postman调用如图所示，只能使用raw\_json格式调用**  
![postman实例][postman]  
**使用java代码发送http请求实现此种方式的接口调用**

public String doPostJson(String url, String putData, String encoding) throws ParseException {
        
            String body = "";
            CloseableHttpResponse response = null;
            CloseableHttpClient client = HttpClients.createDefault();
    
            // 向指定资源位置上传内容
            HttpPost httpPost = new HttpPost(url);
            String content_type = HttpHeaders.CONTENT_TYPE;
            String accept = HttpHeaders.ACCEPT;
            httpPost.addHeader(content_type, "application/json;charset=utf-8");
            httpPost.setHeader(accept,"application/json");
            httpPost.setEntity(new StringEntity(putData, Charset.forName("UTF-8")));
    
            try {
        
                response = client.execute(httpPost);
                System.err.println("status" + response.getStatusLine().getStatusCode());
    
                // 通过response中的getEntity()方法获取返回值
                HttpEntity entity = response.getEntity();
                if (entity != null) {
        
                    body = EntityUtils.toString(entity, encoding);
                }
            } catch (Exception e) {
        
                e.printStackTrace();
            } finally {
        
                httpPost.abort();
                if (response != null) {
        
                    EntityUtils.consumeQuietly(response.getEntity());
                }
            }
    
            System.err.println("body:" + body);
            return body;
        }
