Python ftplib:显示FTP上传进度
我使用Python 3.4上传了一个带有FTP的大文件。
我希望能够在上传文件时显示进度百分比。 这是我的代码:
from ftplib import FTP
import os.path
# Init
sizeWritten = 0
totalSize = os.path.getsize('test.zip')
print('Total file size : ' + str(round(totalSize / 1024 / 1024 ,1)) + ' Mb')
# Define a handle to print the percentage uploaded
def handle(block):
sizeWritten += 1024 # this line fail because sizeWritten is not initialized.
percentComplete = sizeWritten / totalSize
print(str(percentComplete) + " percent complete")
# Open FTP connection
ftp = FTP('website.com')
ftp.login('user','password')
# Open the file and upload it
file = open('test.zip', 'rb')
ftp.storbinary('STOR test.zip', file, 1024, handle)
# Close the connection and the file
ftp.quit()
file.close()
如何获得已经在句柄函数中读取的块的数量?
更新
读完cmd的回答后,我将其添加到我的代码中:
class FtpUploadTracker:
sizeWritten = 0
totalSize = 0
lastShownPercent = 0
def __init__(self, totalSize):
self.totalSize = totalSize
def handle(self, block):
self.sizeWritten += 1024
percentComplete = round((self.sizeWritten / self.totalSize) * 100)
if (self.lastShownPercent != percentComplete):
self.lastShownPercent = percentComplete
print(str(percentComplete) + " percent complete")
我打电话给这样的FTP上传:
uploadTracker = FtpUploadTracker(int(totalSize))
ftp.storbinary('STOR test.zip', file, 1024, uploadTracker.handle)
有三种我能想到的非哈希方式。 然后,所有这些变化的变量的“ownwership”:
global
关键字) sizeWritten
成为sizeWritten
