如何使用 Python Requests 模块在 Moodle Rest WS 中创建用户？

Question

我正在尝试使用 Moodle Webservices - Rest Server 创建一个用户，但我卡在了参数的验证上：S 我的代码如下：

import requests

token = 'TOKENNUMBER'
function = 'core_user_create_users'


url = 'http://localhost/webservice/rest/server.php?wstoken={0}&wsfunction={1}&moodlewsformat=json'.format(token,function)

user1 = {'email': 'email@local.host','firstname': 'firstname',
'lastname': 'lastname', 'createpassword': 1,
'username': 'username'}

然后，我尝试发布数据（两种不同的方式）：

requests.post(url,data={'users': user1})
requests.post(url,data={'users': [user1,]})

并且moodle保持返回错误：

Only arrays accepted. The bad value is: \'username\'</DEBUGINFO>

在文档中（可从自己的 Moodle 中获得），其声明：

Argumentos
users (Obrigatório)


Estrutura geral

那么，考虑到这一点，如何使用 python 请求模块创建 Moodle 用户？传过来的数据有什么问题？

Answer 1

要在 Moodle 中使用 REST 服务，函数的参数必须在平面字典中格式化。参数的结构反映在键的名称中。在您的示例中，您有一个参数 courses 是一个列表。因此，您的字典的键将是 courses[0]email、courses[0]firstname、... 对于第一个用户，以及 courses[1]email , courses[1]firstname, ... 第二个等等

users = {'users[0]email': 'email@local.host',
         'users[0]firstname': 'firstname',
         'users[0]lastname': 'lastname', 
         'users[0]createpassword': 1,
         'users[0]username': 'username'}
requests.post(url,data=users)
