|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 缓存机制
|
||||
|
||||
| 配置 | 值 | 说明 |
|
||||
|------|------|------|
|
||||
| 缓存文件 | `data/questions.json` | 本地JSON文件 |
|
||||
| 过期时间 | **永不过期** | 永久保存 |
|
||||
| 去重方式 | 按 `question_content` | 相同题目不重复存储 |
|
||||
| 降级策略 | API失败自动使用本地缓存 | 原始URL失效也能使用 |
|
||||
| API 限频 | 5秒内只请求一次 | 防止并发请求百度 |
|
||||
|
||||
### 缓存文件结构
|
||||
|
||||
```json
|
||||
{
|
||||
"updated": "2024-01-01 12:00:00",
|
||||
"count": 10,
|
||||
"questions": [...]
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 性能优化
|
||||
|
||||
### 已实现优化
|
||||
|
||||
| 优化项 | 说明 |
|
||||
|--------|------|
|
||||
| 静态变量缓存 | 同一请求内多次读取只加载一次文件 |
|
||||
| API 请求锁 | 5秒内多人请求只发一次 API |
|
||||
| 原子写入 | 先写临时文件再 rename，防止数据损坏 |
|
||||
| 去重优化 | 只在写入时去重，读取时不处理 |
|
||||
| 超时控制 | API 超时 5 秒，连接超时 3 秒 |
|
||||
|
||||
### 性能预估
|
||||
|
||||
| 场景 | 响应时间 |
|
||||
|------|----------|
|
||||
| 读取本地缓存 | ~2-5ms |
|
||||
| API 请求成功 | ~200-500ms |
|
||||
| API 限频降级 | ~1ms（直接读缓存） |
|
||||
| 100人并发 | 无压力（读缓存为主） |
|
||||
|
||||
### 查看状态
|
||||
|
||||
```
|
||||
GET /api.php?action=stats
|
||||
```
|
||||
|
||||
返回：
|
||||
```json
|
||||
{
|
||||
"code": 0,
|
||||
"data": {
|
||||
"total_questions": 149,
|
||||
"cache_file_size": "40.5 KB",
|
||||
"last_updated": "2026-03-29 05:04:04",
|
||||
"memory_usage": "256 KB"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 错误码
|
||||
|
||||
| code | 说明 |
|
||||
|------|------|
|
||||
| 0 | 成功 |
|
||||
| 400 | 参数错误 |
|
||||
| 404 | 题目不存在 |
|
||||
|
||||

|
||||
|
||||
## 使用示例
|
||||
|
||||
### JavaScript
|
||||
```javascript
|
||||
// 获取第一题
|
||||
fetch('/api.php?action=question&id=0')
|
||||
.then(r => r.json())
|
||||
.then(d => console.log(d.data.question));
|
||||
|
||||
// 获取下一题（自动进度，无需传 id）
|
||||
fetch('/api.php?action=next')
|
||||
.then(r => r.json())
|
||||
.then(d => console.log(d.data.id, d.data.question));
|
||||
|
||||
// 提交答案
|
||||
fetch('/api.php?action=answer&id=0&answer=2')
|
||||
.then(r => r.json())
|
||||
.then(d => {
|
||||
if(d.data.correct) {
|
||||
console.log('回答正确！');
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### Flutter/Dart
|
||||
```dart
|
||||
import 'package:dio/dio.dart';
|
||||
|
||||
final dio = Dio();
|
||||
|
||||
// 获取题目
|
||||
Future<Map> getQuestion(int id) async {
|
||||
final res = await dio.get('/api.php', queryParameters: {
|
||||
'action': 'question',
|
||||
'id': id,
|
||||
});
|
||||
return res.data['data'];
|
||||
}
|
||||
|
||||
// 获取下一题（自动进度，无需传 id）
|
||||
Future<Map> getNextQuestion() async {
|
||||
final res = await dio.get('/api.php', queryParameters: {
|
||||
'action': 'next',
|
||||
});
|
||||
return res.data['data'];
|
||||
}
|
||||
|
||||
// 提交答案（POST 方式）
|
||||
Future<bool> checkAnswer(int id, String answer) async {
|
||||
final res = await dio.post('/api.php', data: {
|
||||
'action': 'answer',
|
||||
'id': id,
|
||||
'answer': answer,
|
||||
});
|
||||
return res.data['data']['correct'];
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## App 集成建议
|
||||
|
||||
### 方案 1：App 自己管理进度（推荐）
|
||||
|
||||
使用 `?action=question` 接口，App 完全控制进度：
|
||||
|
||||
```dart
|
||||
class QuizApi {
|
||||
int _currentId = 0;
|
||||
int _total = 0;
|
||||
|
||||
Future<Map> getQuestion() async {
|
||||
final res = await dio.get('/api.php', queryParameters: {
|
||||
'action': 'question',
|
||||
'id': _currentId,
|
||||
});
|
||||
final data = res.data['data'];
|
||||
_total = data['total'] ?? 0;
|
||||
return data;
|
||||
}
|
||||
|
||||
Future<Map> submitAnswer(String answer) async {
|
||||
final res = await dio.post('/api.php', data: {
|
||||
'action': 'answer',
|
||||
'id': _currentId,
|
||||
'answer': answer,
|
||||
});
|
||||
return res.data['data'];
|
||||
}
|
||||
|
||||
void nextQuestion() {
|
||||
_currentId++;
|
||||
if (_currentId >= _total) {
|
||||
_currentId = 0;
|
||||
}
|
||||
}
|
||||
|
||||
int get currentId => _currentId;
|
||||
}
|
||||
```
|
||||
|
||||
**优点**：
|
||||
- 不依赖 Session，App 完全控制进度
|
||||
- 可以随时跳转任意题目
|
||||
- 适合多端同步
|
||||
|
||||
---
|
||||
|
||||
### 方案 2：使用自动进度
|
||||
|
||||
使用 `?action=next` 接口，API 自动管理：
|
||||
|
||||
```dart
|
||||
Future<Map> getNextQuestion() async {
|
||||
final res = await dio.get('/api.php', queryParameters: {
|
||||
'action': 'next',
|
||||
});
|
||||
return res.data['data'];
|
||||
}
|
||||
```
|
||||
|
||||
**优点**：
|
||||
- 简单，无需管理 ID
|
||||
- 自动循环
|
||||
|
||||
**缺点**：
|
||||
- 依赖 Session，需要保持 cookie
|
||||
- 无法自由跳转题目
|
||||
|
||||
---
|
||||
|
||||
### 方案 3：不断获取新题
|
||||
|
||||
使用 `?action=fetch` 接口，每次都从百度获取新题：
|
||||
|
||||
```dart
|
||||
Future<Map> getNewQuestion() async {
|
||||
final res = await dio.get('/api.php', queryParameters: {
|
||||
'action': 'fetch',
|
||||
});
|
||||
return res.data['data'];
|
||||
}
|
||||
```
|
||||
|
||||
**适用场景**：
|
||||
- 想要不断扩展题库
|
||||
- 用户每次刷新都可能看到新题
