SimpleHTTPServerのdo_POSTメソッドを使用してファイルを受信しています。スクリプトはcurlを使用してpngファイルをアップロードするとうまくいきますが、ファイルをアップロードするためにPythonリクエストライブラリを使用するたびに、ファイルはアップロードされますが破損します。ここでSimpleHTTPServerコードはファイルをアップロードするためのクライアント側のコードはここにファイルを受け取るPython SimpleHTTPServer

ファイルアップロードに成功したが破損しました。カール使用
[カール-F '[email protected]' を192.168.5.134:8000/ -v]、ファイルアップロードし、正常に開かれました。
python-request codeに問題はありますか?
