## 💰 **积分消耗规则**
|
||
|
||
文生视频的积分消耗计算方式：
|
||
- **基础消耗**: 15积分
|
||
- **时长消耗**: 每1秒消耗3积分
|
||
- **高清模式**: 额外消耗25积分
|
||
|
||
**示例**:
|
||
- 5秒普通视频: 15 + (5 × 3) = 30积分
|
||
- 10秒高清视频: 15 + (10 × 3) + 25 = 70积分
|
||
|
||
## 🔧 **前端集成示例**
|
||
|
||
### 创建任务
|
||
```javascript
|
||
import { textToVideoApi } from '@/api/textToVideo'
|
||
|
||
const createTask = async () => {
|
||
try {
|
||
const params = {
|
||
prompt: "一只可爱的小猫在花园里玩耍",
|
||
aspectRatio: "16:9",
|
||
duration: 5,
|
||
hdMode: false
|
||
}
|
||
|
||
const response = await textToVideoApi.createTask(params)
|
||
|
||
if (response.data.success) {
|
||
console.log('任务创建成功:', response.data.data)
|
||
// 开始轮询任务状态
|
||
startPolling(response.data.data.taskId)
|
||
}
|
||
} catch (error) {
|
||
console.error('创建任务失败:', error)
|
||
}
|
||
}
|
||
```
|
||
|
||
### 轮询任务状态
|
||
```javascript
|
||
const startPolling = (taskId) => {
|
||
const stopPolling = textToVideoApi.pollTaskStatus(
|
||
taskId,
|
||
// 进度回调
|
||
(progressData) => {
|
||
console.log('进度:', progressData.progress + '%')
|
||
},
|
||
// 完成回调
|
||
(taskData) => {
|
||
console.log('任务完成:', taskData.resultUrl)
|
||
},
|
||
// 错误回调
|
||
(error) => {
|
||
console.error('任务失败:', error.message)
|
||
}
|
||
)
|
||
|
||
// 需要时停止轮询
|
||
// stopPolling()
|
||
}
|
||
```
|
||
|
||
## 🛡️ **安全说明**
|
||
|
||
1. **认证要求**: 所有API都需要JWT认证
|
||
2. **权限控制**: 用户只能访问自己的任务
|
||
3. **参数验证**: 严格的输入参数验证
|
||
4. **错误处理**: 完善的错误处理和日志记录
|
||
|
||
## 📝 **错误码说明**
|
||
|
||
| 错误码 | 说明 | 解决方案 |
|
||
|--------|------|----------|
|
||
| 400 | 参数错误 | 检查请求参数格式和内容 |
|
||
| 401 | 未认证 | 提供有效的JWT Token |
|
||
| 403 | 权限不足 | 确保有访问权限 |
|
||
| 404 | 任务不存在 | 检查任务ID是否正确 |
|
||
| 500 | 服务器错误 | 联系技术支持 |
|
||
|
||
## 🚀 **最佳实践**
|
||
|
||
1. **任务创建**: 创建任务后立即开始轮询状态
|
||
2. **错误处理**: 实现完善的错误处理和用户提示
|
||
3. **资源清理**: 页面卸载时停止轮询
|
||
4. **用户体验**: 提供清晰的进度反馈和状态显示
|
||
5. **性能优化**: 合理设置轮询间隔，避免频繁请求
