# springboot+http请求转换 #

\#\#此文章记录一下项目需要小程序和pc相互调用相同业务逻辑的接口，此方法需要请求报文中添加目标url，无其它多余代码开发

# http请求 #

后面再专门学习http  
1.方法+url+协议/版本  
2.请求头  
3.主题

    方式二

    		String responseData = "";

    			StringRequestEntity requestEntity = new StringRequestEntity(json, "application/json", "UTF-8");
    			postMethod.setRequestEntity(requestEntity);
    			int statusCode = httpClient.executeMethod(postMethod);
    			if (statusCode == HttpStatus.SC_OK) { 
    				responseData =  postMethod.getResponseBodyAsString();
    			}
    		} catch (Exception e) { 
    			Logger logger = Logger.getLogger(e.toString());
    			throw new ExecutionException(e);
    		}finally{ 
    			postMethod.releaseConnection();
    		}
