Android FTP服务器上传文件如何实现?
这篇文章将为大家详细讲解有关Android FTP服务器上传文件如何实现?,小编觉得挺实用的,因此分享给大家做个参考,希望大家阅读完这篇文章后可以有所收获。
Ftp相关代码
import android.util.Log; import org.apache.commons.net.ftp.FTP; import org.apache.commons.net.ftp.FTPClient; import org.apache.commons.net.ftp.FTPReply; import java.io.FileInputStream; public class FTPClientUtils { private static final String TAG = "MainActivity"; private FTPClient ftpClient = null; // FTP客户端 /** * 连接到FTP服务器 * * @param host ftp服务器域名 * @param username 访问用户名 * @param password 访问密码 * @param port 端口 * @return 是否连接成功 */ public boolean ftpConnect(String host, String username, String password, int port) { try { ftpClient = new FTPClient(); ftpClient.connect(host,port); // 根据返回的状态码,判断链接是否建立成功 if (FTPReply.isPositiveCompletion(ftpClient.getReplyCode())) { boolean status = ftpClient.login(username, password); /* * 设置文件传输模式 * 避免一些可能会出现的问题,在这里必须要设定文件的传输格式。 * 在这里我们使用BINARY_FILE_TYPE来传输文本、图像和压缩文件。 */ ftpClient.setFileType(FTP.BINARY_FILE_TYPE); ftpClient.enterLocalPassiveMode(); return status; } } catch (Exception e) { e.printStackTrace(); } return false; } /** * 断开ftp服务器连接 * * @return 断开结果 */ public boolean ftpDisconnect() { // 判断空指针 if (ftpClient == null) { return true; } // 断开ftp服务器连接 try { ftpClient.logout(); ftpClient.disconnect(); return true; } catch (Exception e) { e.printStackTrace(); } return false; } /** * ftp 文件上传 * * @param srcFilePath 源文件目录 * @param desFileName 文件名称 * @return 文件上传结果 */ public boolean ftpUpload(String srcFilePath, String desFileName) { boolean status = false; try { FileInputStream srcFileStream = new FileInputStream(srcFilePath); status = ftpClient.storeFile(desFileName, srcFileStream); srcFileStream.close(); return status; } catch (Exception e) { e.printStackTrace(); } return status; } /** * ftp 更改目录 * * @param path 更改的路径 * @return 更改是否成功 */ public boolean ftpChangePath(String path) { boolean status = false; try { status = ftpClient.changeWorkingDirectory(path); } catch (Exception e) { e.printStackTrace(); } return status; } }
2.调用api
boolean isConnect = mFtpClient.ftpConnect("服务器host", "用户名", "密码", 21);//默认端口号是21 if (isConnect) { boolean isSuccessful = mFtpClient.ftpUpload("/sdcard/" + folderName + "/" + mPicturename, "/htdocs/pics/" + mPicturename); if (isSuccessful) { mFtpClient.ftpDisconnect(); //上传成功 } else { //上传失败 } } else { //服务器连接失败 }
附录:自己之前做项目的时候写过的FTP上传代码:
