[网络协议]httpClient请求，post方法发送数据乱码，

post方法请求乱码 ，在请求时设置body 为 “UTF-8” 即可

@Component
public class HttpUtil {

    public static HttpUtil httpUtil;

    private HttpClient httpClient = HttpClients.createDefault();

    //双重锁
    public static HttpUtil getInstance() {
        if (httpUtil == null) {
            synchronized (HttpUtil.class) {
                if (httpUtil == null) {
                    httpUtil = new HttpUtil();
                }
            }
        }
        return httpUtil;
    }
   /**
     * java发送raw
     */  
 public  JSONObject httpRequest(String url,JSONObject json) {
        JSONObject result = null;
        try {
            @SuppressWarnings({"resource"})
            HttpClient httpClient = HttpClientBuilder.create().build();
            HttpPost post = new HttpPost(url);
            post.setHeader("Content-type", "application/json;charset=UTF-8");
            *StringEntity entity = new StringEntity(json.toJSONString(),"UTF-8");*
            post.setEntity(entity);
            HttpResponse response = httpClient.execute(post);
            String content = EntityUtils.toString(response.getEntity());
            result = (JSONObject) JSONObject.parse(content);
        } catch (IOException e) {
            e.printStackTrace();
        }
        return result;
 ｝
｝
导入jar包：
<!--http请求客户端-->
		<dependency>
			<groupId>org.apache.httpcomponents</groupId>
			<artifactId>httpclient</artifactId>
			<version>4.5.6</version>
		</dependency>
请求方法为：
HttpUtil.getInstance().httpRequest(url，JsonObject);
