sakai webservices 获得某个站点课程所有学生的名字的python代码

以下是使用Sakai Web Services API获取某个站点课程所有学生的名字的Python代码示例：

import requests
import xml.etree.ElementTree as ET

# Sakai Web Services API endpoint
endpoint = 'https://your-sakai-instance.com/sakai-ws/soap/sakai?wsdl'

# Sakai session ID (you need to obtain this from logging in)
session_id = 'your-session-id'

# Site ID of the course site
site_id = 'your-site-id'

# Sakai Web Services API request XML
xml = '''
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://server.webservices.sakai.com">
   <soapenv:Header/>
   <soapenv:Body>
      <ser:getSiteRealm>
         <sessionid>{}</sessionid>
         <siteid>{}</siteid>
      </ser:getSiteRealm>
   </soapenv:Body>
</soapenv:Envelope>
'''.format(session_id, site_id)

# Send the Sakai Web Services API request
response = requests.post(endpoint, data=xml, headers={'Content-Type': 'text/xml'})

# Parse the Sakai Web Services API response to obtain the site realm ID
root = ET.fromstring(response.text)
realm_id = root.find('.//{http://server.webservices.sakai.com}return').text

# Sakai Web Services API request XML to get the list of participants in the course site
xml = '''
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://server.webservices.sakai.com">
   <soapenv:Header/>
   <soapenv:Body>
      <ser:getSiteParticipants>
         <sessionid>{}</sessionid>
         <siteid>{}</siteid>
         <realmid>{}</realmid>
      </ser:getSiteParticipants>
   </soapenv:Body>
</soapenv:Envelope>
'''.format(session_id, site_id, realm_id)

# Send the Sakai Web Services API request to get the participants in the course site
response = requests.post(endpoint, data=xml, headers={'Content-Type': 'text/xml'})

# Parse the Sakai Web Services API response to obtain the list of participants' names
root = ET.fromstring(response.text)
participants = root.findall('.//{http://participantService.ws.sakai.com}participant')
names = [p.find('.//{http://participantService.ws.sakai.com}displayName').text for p in participants]

# Print the list of participants' names
print(names)

请替换 `your-sakai-instance.com`，`your-session-id`，`your-site-id` 为正确的值。注意：要使用此代码示例，您需要已经获得了Sakai Web Services API的访问权限，并且已经通过Sakai登录获得了一个有效的会话ID。
