在Python中尝试使用ftplib将文件上传到FTP服务器时出错

Question

我正在尝试将文件上传到https://dlptest.com/ftp-test/中的测试FTP服务器。我正在ipython控制台中使用Python和ftplib，但是当我调用FTP.storlines（'STORE file1.txt'，open（'file1.txt'））时，出现以下错误：

In [1]: import ftplib, os

In [2]: ftp = ftplib.FTP('ftp.dlptest.com')

In [3]: ftp.login('dlpuser@dlptest.com', 'e73jzTRTNqCN9PYAAjjn')
Out[3]: '230 OK. Current restricted directory is /'

In [4]: ftp.storlines('STOR file1.txt', open('file1.txt'))
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

/usr/lib/python3.7/ftplib.py in storlines(self, cmd, fp, callback)
    536                     break
    537                 if buf[-2:] != B_CRLF:
--> 538                     if buf[-1] in B_CRLF: buf = buf[:-1]
    539                     buf = buf + B_CRLF
    540                 conn.sendall(buf)

TypeError: a bytes-like object is required, not 'str'

当我做ftp.storlines('STOR file1.txt', open('file1.txt', 'rb')时：

In [5]: ftp.storlines('STOR file1.txt', open('file1.txt', 'rb'))

您能帮我找出原因吗？预先谢谢你！
