在界面点击上传图片的按钮,就打开了图库,然后选择需要上传的图片,点击确定,然后在FTP服务器端就有了刚刚上传的图片(可以指定新的文件夹)
求Damo实例
android客户端实现FTP文件需要用到 commons-net-3.0.1.jar
先将jar包复制到android libs目录下
复制以下实现代码
以下为实现代码:
/**
* 通过ftp上传文件
* @param url ftp服务器地址 如:
* @param port 端口如 :
* @param username 登录名
* @param password 密码
* @param remotePath 上到ftp服务器的磁盘路径
* @param fileNamePath 要上传的文件路径
* @param fileName 要上传的文件名
* @return
*/
public String ftpUpload(String url, String port, String username,String password, String remotePath, String fileNamePath,String fileName) {
FTPClient ftpClient = new FTPClient();
FileInputStream fis = null;
String returnMessage = "0";
try {
ftpClient.connect(url, Integer.parseInt(port));
boolean loginResult = ftpClient.login(username, password);
int returnCode = ftpClient.getReplyCode();
if (loginResult && FTPReply.isPositiveCompletion(returnCode)) {// 如果登录成功
ftpClient.makeDirectory(remotePath);
// 设置上传目录
ftpClient.changeWorkingDirectory(remotePath);
ftpClient.setBufferSize(1024);
ftpClient.setControlEncoding("UTF-8");
ftpClient.enterLocalPassiveMode();
fis = new FileInputStream(fileNamePath + fileName);
ftpClient.storeFile(fileName, fis);
returnMessage = "1"; //上传成功
} else {// 如果登录失败
returnMessage = "0";
}
} catch (IOException e) {
e.printStackTrace();
throw new RuntimeException("FTP客户端出错!", e);
} finally {
//IOUtils.closeQuietly(fis);
try {
ftpClient.disconnect();
} catch (IOException e) {
e.printStackTrace();
throw new RuntimeException("关闭FTP连接发生异常!", e);
}
}
return returnMessage;

在安卓环境下可以使用,在java环境下也可以使用,已经在Java环境下实现了功能,然后移植到了安卓手机上,其它都是一样的。
[java] view plain copy

* @param filename

* @return 成功返回true,否则返回false
*/
public static boolean uploadFile(String url, int port, String username,
String password, String path, String filename, InputStream input) {
boolean success = false;
FTPClient ftp = new FTPClient();
try {
int reply;
ftp.connect(url, port);// 连接FTP服务器
// 如果采用默认端口,可以使用ftp.connect(url)的方式直接连接FTP服务器
ftp.login(username, password);//登录
reply = ftp.getReplyCode();
if (!FTPReply.isPositiveCompletion(reply)) {
ftp.disconnect();
return success;
}
ftp.changeWorkingDirectory(path);
ftp.storeFile(filename, input);
input.close();
ftp.logout();
success = true;
} catch (IOException e) {
e.printStackTrace();
} finally {
if (ftp.isConnected()) {
try {
ftp.disconnect();
} catch (IOException ioe) {
}
}
}
return success;
}
// 测试
public static void main(String[] args) {
FileInputStream in = null ;
File dir = new File("G://pathnew");
File files[] = dir.listFiles();
if(dir.isDirectory()) {
for(int i=0;i<files.length;i++) {
try {

boolean flag = uploadFile("17.8.119.77", 21, "android", "android",
"/photo/", "412424123412341234_20130715120334_" + i + ".jpg", in);
System.out.println(flag);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
}

以上为java代码,下面是android代码。
