    self._send_request(method, url, body, headers, encode_chunked)

    (name.title(), data[err.start:err.end], name)) from None
UnicodeEncodeError: 'latin-1' codec can't encode characters in position 195-202: Body ('这个是什么颜色呢') is not valid Latin-1. Use body.encode('utf-8') if you want to send it encoded in UTF-8.

解决办法：在data上加上encode('utf-8')，即data.encode('utf-8')
