１、發送源碼
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.net.HttpURLConnection;
import java.net.URL;
/**
* 通過HTTP上傳文件
* @author cnyqaio@hotmail.com
* @create 2008-4-14
*/
public class PostUrl {
HttpURLConnection conn = null;
BufferedWriter bWriter = null;
OutputStream os = null;
OutputStreamWriter osw = null;
FileReader fr = null;
BufferedReader br = null;
String str = "";
char c = '\n';
String filename = "d:/shchinamobile.log";
/**
* 通過HTTP協議以POST形式發送指定文件至指定url
* @param url
* @throws IOException
*/
public void sendPost(String url) {
try {
File f = new File(filename);
URL url1 = new URL(url);
conn = (HttpURLConnection)url1.openConnection();
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setUseCaches( false);
conn.setDoOutput(true);
osw = new OutputStreamWriter(conn.getOutputStream());
fr = new FileReader(f);
br = new BufferedReader(fr);
while((str = br.readLine()) != null) {
osw.write(str);
osw.write(c);
}
osw.flush() ;
osw.close() ;
if (conn.getResponseCode() != HttpURLConnection.HTTP_OK)
System.out.println( "connect failed!");
} catch (IOException e) {
e.printStackTrace(System.out);
}
finally
{
if (osw != null)
try {
osw.close() ;
} catch (IOException e1) {
e1.printStackTrace(System.out);
}
if (conn != null)
conn.disconnect() ;
}
}
public static void main(String[] args) {
PostUrl pu = new PostUrl();
try {
pu.sendPost("http://127.0.0.1:8080/testjava/testp.jsp");
} catch (Exception e) {
e.printStackTrace();
}
}
}
２、接收JSP
<%
System.err.println("This a struts page.");
//接收上傳的文件內容的臨時文件的文件名
String tempFileName=new String("tempFileName1");
//tempFile1對象指向這個臨時文件
File tempFile1=new File("D:/",tempFileName);
//outputFile1文件輸出流指向這個臨時文件
FileOutputStream outputFile1=new FileOutputStream(tempFile1);
//得到客戶端提交的所有數據
InputStream fileSource1=request.getInputStream();
//將得到的客戶端的數據寫入臨時文件
byte b[]=new byte[1000];
int n;
while((n=fileSource1.read(b))!=-1)
outputFile1.write(b,0,n);
//關閉輸出流和輸入流
outputFile1.close();
fileSource1.close();
%>
已測試通過
還可以通HttpClient來發送，請參照：
