签到天数: 2 天 [LV.1]初来乍到
|
一、发送Get请求
- import java.net.*;
- import java.io.*;
- public class URLSender {
- /** * @param args */
- public static void main(String[] args) throws IOException {
- try {
- Socket socket = new Socket("www.nwu.edu.cn", 80);
- boolean autoflush = true;
- PrintWriter out = new PrintWriter(socket.getOutputStream(), autoflush);
- BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
- //send an HTTP request to the web server
- out.println("GET / HTTP/1.1");
- out.println("Host: nwu.edu.cn");
- out.println("Connection: Close");
- out.println();
- //read the response
- boolean loop = true;
- StringBuffer sb = new StringBuffer(8096);
- while (loop) {
- if (in.ready()) {
- int i = 0;
- while (i != -1) {
- i = in.read();
- sb.append((char) i);
- }
- loop = false;
- }
- //Thread.currentThread().sleep(50);
- }
- //display the response to the out console
- System.out.println(sb.toString());
- socket.close();
- } catch (UnknownHostException e) {
- System.err.println("Don"t know about host: Victest.");
- System.exit(1);
- } catch (IOException e) {
- System.err.println("Couldn"t get I/O for " + "the connection to: Victest.");
- System.exit(1);
- }
- }
- }
复制代码 2、用Socket发送一个POST请求
try {
// Construct data
String data = URLEncoder.encode("key1", "UTF-8") + "=" + URLEncoder.encode("value1", "UTF-8");
data += "&" + URLEncoder.encode("key2", "UTF-8") + "=" + URLEncoder.encode("value2", "UTF-8");
// Create a socket to the host
String hostname = "hostname.com";
int port = 80;
InetAddress addr = InetAddress.getByName(hostname);
Socket socket = new Socket(addr, port);
// Send header
String path = "/Servlet/SomeServlet";
BufferedWriter wr = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream(), "UTF8"));
wr.write("POST "+path+" HTTP/1.0
");
wr.write("Content-Length: "+data.length()+"
");
wr.write("Content-Type: application/x-www-form-urlencoded
");
wr.write("
");
// Send data
wr.write(data);
wr.flush();
// Get response
BufferedReader rd = new BufferedReader(new InputStreamReader(socket.getInputStream()));
String line;
while ((line = rd.readLine()) != null) {
// Process line...
}
wr.close();
rd.close();
} catch (Exception e) {
}
