6. 接口与体验
6.1 开放API
API设计
智能教育系统提供RESTful API,支持第三方系统集成和自定义开发。
API设计原则
- RESTful风格:遵循RESTful设计规范,使用标准HTTP方法
- 统一响应格式:所有API返回统一的JSON格式
- 版本控制:API支持版本控制,通过URL路径指定版本
- 认证授权:所有API需要认证,支持Token和OAuth2.0
- 限流保护:API支持限流,防止滥用
API端点设计
# API端点示例
api_endpoints = {
# 学习相关API
"GET /api/v1/students/{student_id}/learning-path": {
"description": "获取学习者个性化学习路径",
"parameters": {
"student_id": "路径参数,学习者ID"
},
"response": {
"learning_path": [
{
"knowledge_point": "知识点名称",
"order": 1,
"estimated_time": 120,
"resources": []
}
]
}
},
# 答疑相关API
"POST /api/v1/qa/ask": {
"description": "提交问题,获得智能回答",
"request_body": {
"question": "问题内容",
"student_id": "学习者ID",
"subject": "学科",
"context": "上下文信息"
},
"response": {
"answer": "回答内容",
"confidence": 0.95,
"related_resources": []
}
},
# 作业批改API
"POST /api/v1/homework/grade": {
"description": "提交作业,获得批改结果",
"request_body": {
"homework_id": "作业ID",
"answers": [
{
"question_id": "题目ID",
"answer": "学生答案",
"answer_type": "text|image"
}
]
},
"response": {
"results": [
{
"question_id": "题目ID",
"is_correct": True,
"score": 10,
"feedback": "批改反馈"
}
],
"total_score": 100
}
}
}
API响应格式
{
"code": 200,
"message": "success",
"data": {
// 具体数据
},
"timestamp": "2024-01-01T10:00:00Z",
"request_id": "req_123456"
}
