正如Senthil Kumaran指出的那样，参数在ftplib.storbinary函数，但我不知道如何使用它。

我试过这个。每次上传一个字节，我都希望它能打印出消息。

  import ftplib 
 $ b $ def callback （）：
 print（这是回调函数）
 
s = ftplib.FTP（'myserver.com'，'login'，'password'）＃连接
 
f = open（'test.txt'，'rb'）＃发送
的文件s.storbinary（'STOR test.txt'，f，1024，callback（））＃发送文件
 
 f.close（）＃关闭文件和FTP 
 s.quit（）
  

$ p $ import ftplib


def callback（p）：
print（这是回调函数）
$ bs = ftplib.FTP（'myserver.com'，'login'，'password' ）＃连接

f = open（'test.txt'，'rb'）＃文件发送
s.storbinary（'STOR test.txt'，f，1024，callback）＃发送文件

f.close（） ＃关闭文件和FTP
s.quit（）


回调需要稍后调用上。如果在您将其作为参数传递时调用它，则会传递返回值。由于你的回调函数没有返回，它会传入 None 。

I am uploading a file with FTPLib in python and have a cli loadingbar with progressbar 2.2. I need to make a loading bar to tell the progress of the upload.

Does anyone have any info on the topic?

Thanks, giodamelio

As Senthil Kumaran pointed out, there is a callback parameter in the ftplib.storbinary function but I do not know how to use it.

I tried this. I expected it to print the message every time a byte was uploaded.

import ftplib

def callback():
    print("This is the callback function")

s = ftplib.FTP('myserver.com','login','password') # Connect

f = open('test.txt','rb')                # file to send
s.storbinary('STOR test.txt', f, 1024, callback())         # Send the file

f.close()                                # Close file and FTP
s.quit()

解决方案

Small change to your code:

import ftplib

def callback(p):
    print("This is the callback function")

s = ftplib.FTP('myserver.com','login','password') # Connect

f = open('test.txt','rb')                # file to send
s.storbinary('STOR test.txt', f, 1024, callback)         # Send the file

f.close()                                # Close file and FTP
s.quit()

The callback needs to be called later on. If you invoke it as you pass it as a parameter, it's return value is passed instead. Since your callback function has no return, it would pass in None.
