Version de Piwigo: 15.0.0
Version de PHP: 8.1
Version de MySQL:
URL Piwigo: http://galleries.grains-de-culture.fr/

I'm using the API. The responses are in XML format, even though I specified “format”: “json” in my input data (and I understand that json is the default format).
Here's some minimal python code to illustrate the problem

import requests
import configPiwigo as cp
url = "https://galleries.grains-de-culture.fr/ws.php"
auth_data = {
    "format": "json",    "method": "pwg.session.login",
    "username": cp.configPiwigo["login"], "password": cp.configPiwigo["pass"],
}
session = requests.Session()  # Crée une session persistante
response = session.post(url, data={**auth_data, **payload})
if response.ok and response.json().get("stat") == "ok":
    print("Connexion réussie!")

and here's an extract from the response:

response = {Response} <Response [200]>
...
content = {bytes: 64} b'<?xml version="1.0" encoding="utf-8" ?>\n<rsp stat="ok">\n1\n</rsp>'
headers = {CaseInsensitiveDict: 11} {'Date': 'Sat, 09 Nov 2024 14:26:46 GMT', 'Content-Type': 'text/xml; charset=utf-8', 'Transfer-Encoding': 'chunked', 'Connecti...=/,
...
ok = {bool} True
...
status_code = {int} 200
text = {str} '<?xml version="1.0" encoding="utf-8" ?>\n<rsp stat="ok">\n1\n</rsp>'
url = {str} 'https://galleries.grains-de-culture.fr/ws.php'

where we see that the response is ok, the Content-Type text/xml, and above all the content and text are xml.

Is there anything more we can do to get a json response? What else?

Hello,

Can you try putting the format and method directly in the url like this ws.php?format=json&method=pwg.session.login ? In Piwigo to call the api we use this url formatting with only the format and method

Thank'. The following is working and gives a response content in json format

import requests
import configPiwigo as cp
url = "https://galleries.grains-de-culture.fr/ws.php?format=json&method=pwg.session.login"
auth_data = {
    "username": cp.configPiwigo["login"],
    "password": cp.configPiwigo["pass"],
}
session = requests.Session()  # Crée une session persistante
response = session.post(url, data=auth_data)
if response.ok and response.json().get("stat") == "ok":
    print("Connexion réussie!")
