Python's FTP module

Python itself with an FTP module, you can easily implement FTP upload, download and other operations. Here's how to use:

from ftplib import FTPimport socket    #用来设置超时时间FTP.connect(服务器地址,端口,超时时间)      # 连接服务器FTP.login(用户名,用户密码)        # 用户登录FTP.pwd(路径)                    # 读取操作路径FTP.cwd(路径)                    # 设置要操作FTP文件夹路径FTP.nlst()            # 获得目录下文件FTP.retrbinary(文件名, 回调函数)     # 下载FTP上的文件FTP.delete(文件名)                # 删除FTP文件FTP.storbinary(文件名, 文件对象 [,块大小])     # 上传FTP文件FTP.quit()                      # 退出FTP服务器FTP.set_pasv(boolean)           # 是否设置为被动模式FTP.rename(old, new)            # 重命名FTP.delete(path)                # 删除文件FTP.mkd(directory)              # 创建目录

An upload code:

import socketfrom ftplib import FTPftp_server=‘xx.xx.xx.xx‘ftp_user=‘xxxxx‘ftp_password=‘xxxxx‘ftp_backup_dir=‘backup‘newday = date.today()    #获取今天的日期oldday = date.today()-timedelta(5)    #获得5天前的日期newfile = ‘/home/backup/‘ + ‘backup_data_‘ + str(newday.year) + ‘.‘ + str(newday.month) + ‘.‘ +  str(newday.day) + ‘.zip‘    #本次备份文件名(绝对路径)oldfile = ‘/home/backup/‘ + ‘backup_data_‘ + str(oldday.year) + ‘.‘ + str(oldday.month) + ‘.‘ +  str(oldday.day) + ‘.zip‘    #5天前备份的文件名(绝对路径)def upload():    socket.setdefaulttimeout(60)    #超时FTP时间设置为60秒    ftp = FTP(ftp_server)    print("login ftp...")    try:        ftp.login(ftp_user, ftp_password)        print(ftp.getwelcome())   #获得欢迎信息        try:            if ftp_backup_dir in ftp.nlst():                print("found backup folder in ftp server, upload processing.")            else:                print("don‘t found backup folder in ftp server, try to build it.")                ftp.mkd(ftp_backup_dir)        except:            print("the folder" + ftp_backup_dir + "doesn‘t exits and can‘t be create!")            sys.exit()    except:        print("ftp login failed.exit.")        sys.exit()    ftp.cwd(ftp_backup_dir)    #设置FTP路径    print("upload data...")    try:        ftp.storbinary(‘STOR ‘ + os.path.basename(newfile), open(newfile,‘rb‘), 1024)    #上传备份文件    except:        print("upload failed. check your permission.")        print("delte old file...")    try:        ftp.delete(os.path.basename(oldfile))    #删除5天前的备份文件    except:        print("the old file in ftp doesn‘t exists, jumped.")    print("ftp upload successful.exit...")    ftp.quit()if __name__== ‘__main__‘:    upload()

Example 2:

Ftpserver = "192.168.0.1"

#EstablishFtpConnection
FTP = Ftplib. FTP (Ftpserver)
# FTPUser authentication
Ftp.login (' Administrator ',' Sunfast ')
#SwitchFtpOperating Directory
FTP.CWD ("/fromcovisint/094200005560743089chn03_830")
for filenameIn Ftp.nlst ():#GetFtpManipulate all files of the directory
 If Os.path.splitext (filename) [1].upper () = =‘. CSV ':
 If' Finished 'In filename:
 Continue
Else
 Try
 #Download the specified file into the current operation directory
Ftp.retrbinary (' RETR%s '% filename,Open (filename,' WB '). Write)
 #ftp. Storbinary (' STOR%s '% filename, open (filename, ' RB '), Const_buffer_size) FTPUploading files
 #Import data
 Self.import_data (Os.path.join (OS.GETCWD (), filename))
New_filename = os.path.splitext (filename) [0] + "_finished" + os.path.splitext (filename) [1]
# Modify the file name on the FTP directory , using the new file name
Ftp.rename (filename, new_filename)
finally:
# Delete the downloaded file details in the current directory
Os.remove (Os.path.join (OS.GETCWD (), filename)
Ftp.quit ()
