sakai soap 获得某站点所有学生的成绩的python代码

要通过Sakai SOAP API获取某站点所有学生的成绩，可以使用下面的 Python 代码：

import requests
import xml.etree.ElementTree as ET

# 设置Sakai SOAP API的URL和访问令牌
url = "http://your-sakai-server/sakai-ws/soap/sakai?wsdl"
token = "your-access-token"

# 设置SOAP消息体
body = """
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:api="http://api.sakai.org">
    <soapenv:Header>
        <api:sessionid>{}</api:sessionid>
    </soapenv:Header>
    <soapenv:Body>
        <api:getSiteStudentsWithRole>
            <siteId>site-id</siteId>
            <role>Student</role>
        </api:getSiteStudentsWithRole>
    </soapenv:Body>
</soapenv:Envelope>
""".format(token)

# 发送SOAP请求并解析响应
response = requests.post(url, data=body)
root = ET.fromstring(response.content)

# 解析学生列表，并获取每个学生的成绩
students = root.find(".//{http://api.sakai.org}students")
for student in students:
    username = student.find("{http://api.sakai.org}userId").text
    grades_body = """
    <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:api="http://api.sakai.org">
        <soapenv:Header>
            <api:sessionid>{}</api:sessionid>
        </soapenv:Header>
        <soapenv:Body>
            <api:getGradebookForUser>
                <siteId>site-id</siteId>
                <userId>{}</userId>
            </api:getGradebookForUser>
        </soapenv:Body>
    </soapenv:Envelope>
    """.format(token, username)
    grades_response = requests.post(url, data=grades_body)
    grades_root = ET.fromstring(grades_response.content)
    grades = grades_root.find(".//{http://api.sakai.org}grade")
    if grades is not None:
        for grade in grades:
            item_name = grade.find("{http://api.sakai.org}name").text
            score = grade.find("{http://api.sakai.org}score").text
            print("学生{}的{}成绩为{}".format(username, item_name, score))

请注意，代码中的 `your-sakai-server`、`your-access-token` 和 `site-id` 都需要替换为实际的值。此外，此代码使用了Python标准库中的 `requests` 和 `xml.etree.ElementTree` 模块，因此请确保它们已经安装好。
