Я пытаюсь получить доступ к веб-службам установки Moodle, которую я использую, используя библиотеку запросов Python. У меня есть документация по API и пример проекта, написанные на php (я раньше не смотрел на php и это намного сложнее, чем я ожидал понять), но я действительно изо всех сил пытаюсь правильно отформатировать запрос. Сайт возвращает недопустимый обнаруженный параметр, поэтому я уверен, что моя конечная точка, токен авторизации и конфигурация сервера работают, и это просто формат данных, который подводит меня.
Сначала вот ошибка ...
<?xml version="1.0" encoding="UTF-8" ?>
<EXCEPTION class="invalid_parameter_exception">
<ERRORCODE>invalidparameter</ERRORCODE>
<MESSAGE>Invalid parameter value detected</MESSAGE>
</EXCEPTION>
А теперь мой код ...
import requests
target = 'http://example.com/moodle/webservice/rest/server.php?'
moodle_create_token = 'xxx'
moodle_enrol_token = 'yyy'
url_payload = {
"wstoken":moodle_create_token,
"wsfunction":"core_user_create_users"
}
###not sure if I should just be passing this as a dict or some deeper more layered struct
payload = {
"username":"testuser",
"password":'testpass',
"firstname":'testf',
"lastname":'testl',
"email":"test@example.com",
"idnumber":"1234"
}
###not sure how to include the payload as the last argument in the function (currently data=)
###I feel like at this point I've just been throwing random data at it and hoping something sticks haha.
r=requests.post(target, params=url_payload, data=payload)
Вот документация сайта
Общая структура Moodle API
XML-RPC Moodle API (структура PHP)
Moodle API REST (параметры POST)
формат ответа Moodle 1
формат ответа Moodle 2
Наконец, пример в php.
