在开发中,会遇到向ftp服务器上传文件的需求,首先要导入
commons-net-3.3.jar 然后利用api进行相关操作,具体功能如下:
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:
