[英]Python ftplib UnicodeEncodeError when trying to upload an XML with unicode content
I am trying to upload an XML with unicode content to a FTP server using ftplib, but getting the following exception when I try to upload the using storbinary method. 我正在尝试使用ftplib将具有Unicode内容的XML上载到FTP服务器,但是当我尝试使用storbinary方法上载时出现以下异常。 The XML data is properly encoded to unicode (utf-8), I have made sure of that, I am not sure as to why storbinary is trying to encode it to 'ascii' while uploading.
XML数据已正确编码为unicode(utf-8),我已经确定了这一点,我不确定为什么storbinary试图在上传时将其编码为“ ascii”。 Can anyone please help?
谁能帮忙吗?

You should pass a file opened in a binary mode to ftp.storbinary()
. 您应该将以二进制模式打开的文件传递给
ftp.storbinary()
。 For example, if you want to upload a Unicode string as a filename
file: 例如,如果要上载Unicode字符串作为
filename
文件:
import io
assert isinstance(unicode_string, unicode)
file = io.BytesIO(unicode_string.encode("utf-8"))
ftp.storbinary("STOR filename", file)
If unicode_string
contains xml; 如果
unicode_string
包含xml; make sure that the character encoding used in the xml declaration is consistent with the encoding you use to store the file. 确保xml声明中使用的字符编码与用于存储文件的编码一致。
I was able to find the solution, the comment by @Cairnarvon was partially correct, I was encoding the string, but there were other bits of the string written to the StringIO instance that were not encoded. 我能够找到解决方案,@ Cairnarvon的注释部分正确,我正在编码字符串,但是写入StringIO实例的字符串中还有其他未编码的位。 Finally I ended up creating the XML bit and encoding it as a whole.
最后,我最终创建了XML位并对其进行了整体编码。 You can see my code in the pastebin link below;
