利用HttpClient发送json请求的简单方法

public class POSTbasic {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        String from = "18176254331";
        String to = "13757526793";
        SimpleDateFormat nowtime = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");//设置日期格式
        String time = nowtime.format(new Date());
        String content = "aGVsbG8gd29ybGQ=";
        String enc = "utf8";
        System.out.println(time);
        
        String reqId=RandomStringUtils.randomAlphanumeric(11);
        String path = "http://10.17.33.11:18080/spnscp/nel/cincc/sms/recv";

        String body1 = "{\n" +
                "    \"reqId\":\""+reqId+"\",\n" +
                "    \"from\":\""+from+"\",\n" +
                "    \"to\":\""+to+"\",\n" + 
                "    \"smsId\":\""+reqId+"\",\n" +
                "    \"sendTime\":\""+time+"\",\n" +
                "    \"recvTime\":\""+time+"\",\n" +
                "    \"content\":\""+content+"\",\n" +
                     "    \"enc\":\""+enc+"\"\n";
        String body2 = "}";
        String body = body1+body2;
        System.out.println(body);

        try{
            requesttestHTTPCLIENT.Postrequest(path, body);
            
        }catch(Exception e){
             e.printStackTrace();
        }
    }
