Panel REST API

CongTang · September 28, 2022, 12:48pm

Hi
I am trying to run the rest API example which i find from:

gist.github.com

https://gist.github.com/MarcSkovMadsen/5ccea41b801a8b9f3c555a5b2968586d

messages.py

import ast
import requests

url = 'http://localhost:5006/rest/post_data'

def post(value):
    data = {'data': value}
    response = requests.post(url, data = data)
    if response.status_code==200:
        print(ast.literal_eval(response.text))

rest_app.py

"""Panel provides functionality for integration with REST API providers. Currently Param and 
Tranquilizer.

When you `panel serve` the `script.py` you need to add `--rest-provider param` or 
`--rest-provider tranquilizer` to serve the REST API.

For more check out the [REST APIs Introduction](https://blog.holoviz.org/panel_0.10.0.html#REST-APIs)
"""
import param
import panel as pn

This file has been truncated. show original

when I run panel serve app.py --rest-provider tranquilizer --autoreload i get a error of:
cannot import name ‘parse_rule’ from ‘werkzeug.routing’

So I solved it by installing pip install Werkzeug==2.1.2

But it turns out to:
ERROR: init() got an unexpected keyword argument ‘unbound_message’

And here is my env:
Werkzeug==2.1.2
tranquilizer==0.8.0
panel==0.13.1

Is there my environment issue or i didn’t run the example properly
Do we have any ideas there? Any comments while being grateful

Kind regards
Victor

Hi

The bug has been figured out by downgrading flask and Werkzeug to 2.1.2

thanks
