我是否访问curl param错误（文件名）？或者我以错误的方式发送文件？
尝试做
f = request.files ['filename']
同样的错误。 hello.json 并将其放在请求的正文中。 （这个特性实际上非常有用，如果你有大量的JSON需要发送到服务器）。

curl command code is doing is reading the file hello.json and putting it in the body of the request. (This feature is actually very useful if you have a large chunk of JSON you need to send to the server).application/json requests you send the JSON as the body of the request, so this may be what you want. You can use request.get_json to get this data as a Python dictionary.-F parameter. (See also: an SO answer about this: https://stackoverflow.com/a/12667839/224334 ).
