We needed to support uploading a file using a form as well as via an endpoint. To make sure that works I built this demonstrator that does both, it uses this rather nice jQuery plugin
It's Python so assuming you have a venv you can do this:
$ pip install -U -r requirements.txt
$ python server.py
* Running on http://0.0.0.0:5001/ (Press CTRL+C to quit)
* Restarting with stat
* Debugger is active!
* Debugger pin code: 105-027-218
Hit that link and you can play around with the simple setup and serve/upload files from your /tmp directory using both jQuery and regular forms. jQuery uploads are automatic and get added as 'Auto Upload' to the list on the main page.
You can either use the main page to upload or use the excellent httpie and you can do
things like this to hit the upload endpoint:
$ http --form POST localhost:5001/upload file@/home/nglynn/Pictures/welcome.gif
HTTP/1.0 200 OK
Content-Length: 71
Content-Type: application/json
Date: Wed, 10 Aug 2016 01:36:22 GMT
Server: Werkzeug/0.11.8 Python/3.4.3
{
"message": "success",
"result": "/v/welcome.gif",
"status": "success"
}
of course it only checks file names but that's enough for now:
$ http --form POST localhost:5001/upload file@/home/nglynn/readme.md
HTTP/1.0 500 INTERNAL SERVER ERROR
Content-Length: 60
Content-Type: application/json
Date: Wed, 10 Aug 2016 01:40:12 GMT
Server: Werkzeug/0.11.8 Python/3.4.3
{
"error_code": "None",
"message": "Nope",
"status": "error"
}
It will give you a 413 error if you upload a file larger than 16MB.
Hopefully it's fairly short and sweet. Uses /static for files, /templates for HTML and uses the best
bits of Flask as well as our json_response object to keep things standard.
I developed in Python3 and you will want to setup a venv and use the requirements.txt to set up the dependencies.
$ pip install -U -r requirements.txt
$ python server.py
It's a fairly simple, unstyled app. Feel free to build it out and let me know and I'll add you to the resource list.
