Spring学习笔记（三十五）：关于httpClient的post请求，到后台中文乱码的问题

• 问题描述：用HttpClient的post进行请求，发现如果post的数据中有中文，那么到后台存进数据库的时候就会乱码；
• 原因分析：是编码问题
• 解决办法：在提交数据的时候，进行编码UTF-8
  代码如下：

public static String postJson(String url,String jsonString) throws Exception{        CloseableHttpClient httpClient = HttpClients.createDefault();        HttpPost httpPost = new HttpPost(url);        //下面这里要加个编码参数：UTF-8，否则提交到接口后，中文会乱码        StringEntity strEntity = new StringEntity(jsonString,"UTF-8");        httpPost.setEntity(strEntity);        String result = "";        try{            CloseableHttpResponse response = httpClient.execute(httpPost);            HttpEntity httpEntity = response.getEntity();            result = EntityUtils.toString(httpEntity,"UTF-8");        }finally{            httpClient.close();        }        return result;    }
