以Post方法向服务器提交json数据

json数据格式

{"time":"12:03","freq":14.853,"ultrasound":0.17,"energy":0.10,"power":0.946,"count":1860,"status":true}

Socket 模拟Http访问

String postParams = "{\"time\":\"12:05\",\"freq\":14.853,\"ultrasound\":0.17,\"energy\":0.10,\"power\":0.946,\"count\":1860,\"status\":true}";

//上面java双引号需要斜线转义

int paramsLen = postParams.length();

StringBuffer post = new StringBuffer(512);

post.append("POST /addRecords HTTP/1.1\r\n");

post.append("Host: 172.93.46.196\r\n");

post.append("Accept: text/html\r\n");

post.append("Connection: Close\r\n");

post.append("Content-Length: " + paramsLen + "\r\n");

post.append("Content-Type: application/json\r\n");

post.append("\r\n");

post.append(postParams);

Socket socket = new Socket("172.93.46.196", 8300);

PrintWriter outWriter = new PrintWriter(socket.getOutputStream());

outWriter.println(post);

outWriter.flush();
