I have a script(test.py) to test some api, like this:
def get_response(fct, data, method=GET):
"""
Performs the query to the server and returns a string containing the
response.
"""
assert(method in (GET, POST))
url = f'http://{hostname}:{port}/{fct}'
if method == GET:
encode_data = parse.urlencode(data)
response = request.urlopen(f'{url}?{encode_data}')
elif method == POST:
response = request.urlopen(url, parse.urlencode(data).encode('ascii'))
return response.read()
In terminal I call:
python test.py -H 0.0.0.0 -P 5000 --add-data
The traceback:
Traceback (most recent call last):

urllib.error.HTTPError: HTTP Error 400: BAD REQUEST
The data is {"name": "Channel1"}. I couldn't understand what is wrong. Please can someone give some tip or show whats's wrong?
When I call using curl, works:
curl -X POST -H "Content-Type: application/json" -d '{"name": "Channel1"}' http://0.0.0.0:5000/add_channel
I solved the problem change the test script:
Here is the fixed code:
def get_response(fct, data, method=GET):
"""
Performs the query to the server and returns a string containing the
response.
"""
assert(method in (GET, POST))
url = f'http://{hostname}:{port}/{fct}'
if method == GET:
encode_data = parse.urlencode(data)
req = request.Request(f'{url}?{encode_data}'
, headers={'content-type': 'application/json'})
response = request.urlopen(req)
elif method == POST:
params = json.dumps(data)
binary_data = params.encode('utf8')
req = request.Request(url
, data= binary_data
, headers={'content-type': 'application/json'})
response = request.urlopen(req)
x = response.read()
return x
