今天开始学习Android开发
先了解了基本功能、
ublic class webs {
public String executeHttpGet2(){
HttpURLConnection connection = null;
InputStream in = null;
try{
String Url = "http://192.168.0.105:8080/temperature/s";
try {

connection = (HttpURLConnection)url.openConnection();
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setRequestMethod("POST");
connection.setReadTimeout(8000);//传递数据超时
connection.setUseCaches(false);
connection.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
connection.connect();
int resultCode = connection.getResponseCode();
if(HttpURLConnection.HTTP_OK == resultCode) {
in = connection.getInputStream();
return parseInfo(in);
}
return null;
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}catch (Exception e){
e.printStackTrace();
}finally {
//意外退出时，连接关闭保护
if(connection != null){
connection.disconnect();
}
if(in != null){
try{
in.close();
}catch (Exception e){
e.printStackTrace();
}
}
}
return null;
}

//得到字节输入流，将字节输入流转化为String类型
public static String parseInfo(InputStream inputStream){
