tomcat注意要把这个配置
client端核心代码：
public static boolean post2(String url) {
File file = new File("D:/psu.jpg");InputStream in = null;String responseContent = null;try {in = new FileInputStream(file);} catch (FileNotFoundException e1) {e1.printStackTrace();}
try {if (url == null || url.trim().equals("")) {
throw new Exception("目标url地址无效");
}
URL url2 = new URL(url);HttpURLConnection hc = (HttpURLConnection) url2.openConnection();hc.setRequestMethod("POST");
System.setProperty("sun.net.client.defaultConnectTimeout",String.valueOf(HttpTest.connectTimeOut));// （单位：毫秒）jdk1.4换成这个,连接超时System.setProperty("sun.net.client.defaultReadTimeout",String.valueOf(HttpTest.readTimeOut));
hc.setDoOutput(true);OutputStream os = hc.getOutputStream();// hc.getInputStream();byte[] tempbytes = new byte[100];int byteread = 0;while ((byteread = in.read(tempbytes)) != -1) {os.write(tempbytes, 0, byteread);
System.out.println(byteread);}os.flush();os.close();
InputStream input = hc.getInputStream();//严重注意，只有有了客户端的这部分的 读 的代码，才会有 写 的过程BufferedReader rd = new BufferedReader(new InputStreamReader(input,"GBK"));String tempLine = rd.readLine();StringBuffer tempStr = new StringBuffer();String crlf = System.getProperty("line.separator");while (tempLine != null) {tempStr.append(tempLine);tempStr.append(crlf);tempLine = rd.readLine();}responseContent = tempStr.toString();rd.close();input.close();
hc.disconnect();} catch (Exception e) {e.printStackTrace();return false;
}try {in.close();} catch (IOException e) {e.printStackTrace();}
return true;
}
server端核心代码
protected void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException {
String fileName = "D:/copy.jpg";RandomAccessFile file = null;ServletInputStream sis = null;
try {file = new RandomAccessFile(fileName, "rw");
sis = request.getInputStream();byte[] buf = new byte[1024];int len = sis.read(buf);while (len != -1) {System.out.println(len);file.write(buf, 0, len);len = sis.read(buf);}} catch (Exception e) {e.printStackTrace();} finally {if (file != null)file.close();
}if (sis != null)sis.close();
}
爱的力量大到可以使人忘记一切，
