1.标准的java接口

try {
URL url=new URL("www.baidu.com");
HttpURLConnection http=(HttpURLConnection) url.openConnection();
int nrc=http.getResponseCode();
if(nrc==HttpURLConnection.HTTP_OK){
//处理数据
}
} catch (Exception e) {
// TODO: handle exception
}

2.apache接口

try {
HttpClient hc=new DefaultHttpClient();
HttpGet get=new HttpGet("www.baidu.com");
HttpResponse rp=hc.execute(get);
if(rp.getStatusLine().getStatusCode()==HttpStatus.SC_OK){
//处理数据
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

3.android网络接口

try {
InetAddress inetAddress=InetAddress.getByName("192.168.1.110");
Socket socket=new Socket(inetAddress,8080,true);
InputStream input=socket.getInputStream();
OutputStream outputStream=socket.getOutputStream();
//处理数据

outputStream.close();
input.close();
socket.close();

} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

4.接下来就是最常见的get和post请求:

try {                        HttpURLConnection httpURLConnection = (HttpURLConnection)url.openConnection();            httpURLConnection.setConnectTimeout(3000);        　　//设置连接超时时间            httpURLConnection.setDoInput(true);                  //打开输入流，以便从服务器获取数据            httpURLConnection.setDoOutput(true);                 //打开输出流，以便向服务器提交数据            httpURLConnection.setRequestMethod("POST");    　　　 //设置以Post方式提交数据            httpURLConnection.setUseCaches(false);               //使用Post方式不能使用缓存            //设置请求体的类型是文本类型            httpURLConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");            //设置请求体的长度            httpURLConnection.setRequestProperty("Content-Length", String.valueOf(data.length));            //获得输出流，向服务器写入数据            OutputStream outputStream = httpURLConnection.getOutputStream();            outputStream.write(data);                        int response = httpURLConnection.getResponseCode();            //获得服务器的响应码            if(response == HttpURLConnection.HTTP_OK) {                InputStream inptStream = httpURLConnection.getInputStream();                return dealResponseResult(inptStream);                     //处理服务器的响应结果            }        } catch (IOException e) {            e.printStackTrace();        }
