# Products API 文档
|
||||
|
||||
## 概述
|
||||
|
||||
Products API 提供轻量级的产品查询接口，专门为前端下拉框和自动完成功能设计。
|
||||
|
||||
**特点**:
|
||||
- 只返回 `id` 和 `name` 字段，减少数据传输
|
||||
- 支持分页（LimitOffset）
|
||||
- 支持按名称模糊搜索
|
||||
- 需要 JWT 认证
|
||||
|
||||
**基础路径**: `/api/v1/products/quick/`
|
||||
|
||||
---
|
||||
|
||||
## 认证
|
||||
|
||||
所有接口都需要 JWT 认证。在请求头中添加：
|
||||
|
||||
```
|
||||
Authorization: Bearer <access_token>
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 接口详情
|
||||
|
||||
### 获取产品列表
|
||||
|
||||
**请求**
|
||||
|
||||
```
|
||||
GET /api/v1/products/quick/
|
||||
```
|
||||
|
||||
**查询参数**
|
||||
|
||||
| 参数 | 类型 | 必填 | 说明 |
|
||||
|------|------|------|------|
|
||||
| limit | integer | 否 | 返回结果数量，不提供则返回所有 |
|
||||
| offset | integer | 否 | 偏移量，默认 0 |
|
||||
| search | string | 否 | 按产品名称模糊搜索（不区分大小写） |
|
||||
|
||||
**请求示例**
|
||||
|
||||
```bash
|
||||
# 获取所有产品
|
||||
curl -X GET "http://localhost:8000/api/v1/products/quick/" \
|
||||
-H "Authorization: Bearer YOUR_TOKEN"
|
||||
|
||||
# 分页获取（前10条）
|
||||
curl -X GET "http://localhost:8000/api/v1/products/quick/?limit=10&offset=0" \
|
||||
-H "Authorization: Bearer YOUR_TOKEN"
|
||||
|
||||
# 按名称搜索
|
||||
curl -X GET "http://localhost:8000/api/v1/products/quick/?search=布料" \
|
||||
-H "Authorization: Bearer YOUR_TOKEN"
|
||||
|
||||
# 搜索 + 分页
|
||||
curl -X GET "http://localhost:8000/api/v1/products/quick/?search=布料&limit=5&offset=0" \
|
||||
-H "Authorization: Bearer YOUR_TOKEN"
|

```
|
||||
|
||||

|
||||
|
||||
## 使用场景
|
||||
|
||||
### 1. 前端下拉框
|
||||
|
||||
```javascript
|
||||
// React 示例
|
||||
import { useState, useEffect } from 'react';
|
||||
|
||||
function ProductSelect() {
|
||||
const [products, setProducts] = useState([]);
|
||||
const [loading, setLoading] = useState(false);
|
||||
|
||||
useEffect(() => {
|
||||
const fetchProducts = async () => {
|
||||
setLoading(true);
|
||||
const response = await fetch('/api/v1/products/quick/?limit=100', {
|
||||
headers: {
|
||||
'Authorization': `Bearer ${token}`
|
||||
}
|
||||
});
|
||||
const data = await response.json();
|
||||
setProducts(data.results);
|
||||
setLoading(false);
|
||||
};
|
||||
|
||||
fetchProducts();
|
||||
}, []);
|
||||
|
||||
return (
|
||||
<select>
|
||||
{products.map(product => (
|
||||
<option key={product.id} value={product.id}>
|
||||
{product.name}
|
||||
</option>
|
||||
))}
|
||||
</select>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 自动完成（Autocomplete）
|
||||
|
||||
```javascript
|
||||
// Vue 3 + Element Plus 示例
|
||||
<template>
|
||||
<el-autocomplete
|
||||
v-model="searchText"
|
||||
:fetch-suggestions="queryProducts"
|
||||
placeholder="搜索产品"
|
||||
@select="handleSelect"
|
||||
/>
|
||||
</template>
|
||||
|
||||
<script setup>
|
||||
import { ref } from 'vue';
|
||||
|
||||
const searchText = ref('');
|
||||
|
||||
const queryProducts = async (queryString, cb) => {
|
||||
const url = queryString
|
||||
? `/api/v1/products/quick/?search=${encodeURIComponent(queryString)}&limit=10`
|
||||
: '/api/v1/products/quick/?limit=10';
|
||||
|
||||
const response = await fetch(url, {
|
||||
headers: {
|
||||
'Authorization': `Bearer ${token}`
|
||||
}
|
||||
});
|
||||
const data = await response.json();
|
||||
|
||||
// 转换为 Element Plus 需要的格式
|
||||
const suggestions = data.results.map(p => ({
|
||||
value: p.name,
|
||||
id: p.id
|
||||
}));
|
||||
|
||||
cb(suggestions);
|
||||
};
|
||||
|
||||
const handleSelect = (item) => {
|
||||
console.log('选中产品:', item.id, item.value);
|
||||
};
|
||||
</script>
|
||||
```
|
||||
|
||||
### 3. 搜索框实时搜索
|
||||
|
||||
```javascript
|
||||
// Vanilla JavaScript 示例
|
||||
const searchInput = document.getElementById('product-search');
|
||||
const resultsContainer = document.getElementById('search-results');
|
||||
|
||||
let debounceTimer;
|
||||
|
||||
searchInput.addEventListener('input', (e) => {
|
||||
clearTimeout(debounceTimer);
|
||||
|
||||
debounceTimer = setTimeout(async () => {
|
||||
const searchText = e.target.value.trim();
|
||||
|
||||
if (searchText.length < 2) {
|
||||
resultsContainer.innerHTML = '';
|
||||
return;
|
||||
}
|
||||
|
||||
const response = await fetch(
|
||||
`/api/v1/products/quick/?search=${encodeURIComponent(searchText)}&limit=10`,
|
||||
{
|
||||
headers: {
|
||||
'Authorization': `Bearer ${token}`
|
||||
}
|
||||
}
|
||||
);
|
||||
|
||||
const data = await response.json();
|
||||
|
||||
// 渲染搜索结果
|
||||
resultsContainer.innerHTML = data.results.map(product => `
|
||||
<div class="search-result" data-id="${product.id}">
|
||||
${product.name}
|
||||
</div>
|
||||
`).join('');
|
||||
}, 300); // 300ms 防抖
|
||||
});
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Python 使用示例
|
||||
|
||||
### 基础查询
|
||||
|
||||
```python
|
||||
import requests
|
||||
|
||||
BASE_URL = "http://localhost:8000"
|
||||
TOKEN = "your_jwt_token"
|
||||
headers = {"Authorization": f"Bearer {TOKEN}"}
|
||||
|
||||
# 获取所有产品
|
||||
response = requests.get(f"{BASE_URL}/api/v1/products/quick/", headers=headers)
|
||||
products = response.json()
|
||||
|
||||
print(f"共有 {products['count']} 个产品:")
|
||||
for product in products['results']:
|
||||
print(f" - {product['id']}: {product['name']}")
|
||||
```
|
||||
|
||||
### 分页查询
|
||||
|
||||
```python
|
||||
def get_all_products(token):
|
||||
"""获取所有产品（自动处理分页）"""
|
||||
BASE_URL = "http://localhost:8000"
|
||||
headers = {"Authorization": f"Bearer {token}"}
|
||||
|
||||
all_products = []
|
||||
offset = 0
|
||||
limit = 50
|
||||
|
||||
while True:
|
||||
response = requests.get(
|
||||
f"{BASE_URL}/api/v1/products/quick/?limit={limit}&offset={offset}",
|
||||
headers=headers
|
||||
)
|
||||
data = response.json()
|
||||
|
||||
all_products.extend(data['results'])
|
||||
|
||||
if data['next'] is None:
|
||||
break
|
||||
|
||||
offset += limit
|
||||
|
||||
return all_products
|
||||
|
||||
# 使用
|
||||
products = get_all_products(token)
|
||||
print(f"总共获取了 {len(products)} 个产品")
|
||||
```
|
||||
|
||||
### 搜索查询
|
||||
|
||||
```python
|
||||
def search_products(token, query, limit=10):
|
||||
"""搜索产品"""
|
||||
BASE_URL = "http://localhost:8000"
|
||||
headers = {"Authorization": f"Bearer {token}"}
|
||||
|
||||
response = requests.get(
|
||||
f"{BASE_URL}/api/v1/products/quick/?search={query}&limit={limit}",
|
||||
headers=headers
|
||||
)
|
||||
|
||||
return response.json()['results']
|
||||
|
||||
# 使用
|
||||
results = search_products(token, "布料", limit=5)
|
||||
for product in results:
|
||||
print(f"{product['id']}: {product['name']}")
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 性能优化建议
|
||||
|
||||
### 前端缓存
|
||||
|
||||
```javascript
|
||||
// 使用本地缓存避免重复请求
|
||||
class ProductCache {
|
||||
constructor() {
|
||||
this.cache = new Map();
|
||||
this.cacheTimeout = 5 * 60 * 1000; // 5分钟
|
||||
}
|
||||
|
||||
async getProducts(search = '', limit = 100) {
|
||||
const cacheKey = `${search}:${limit}`;
|
||||
const cached = this.cache.get(cacheKey);
|
||||
|
||||
if (cached && Date.now() - cached.timestamp < this.cacheTimeout) {
|
||||
return cached.data;
|
||||
}
|
||||
|
||||
const url = search
|
||||
? `/api/v1/products/quick/?search=${encodeURIComponent(search)}&limit=${limit}`
|
||||
: `/api/v1/products/quick/?limit=${limit}`;
|
||||
|
||||
const response = await fetch(url, {
|
||||
headers: {
|
||||
'Authorization': `Bearer ${token}`
|
||||
}
|
||||
});
|
||||
const data = await response.json();
|
||||
|
||||
this.cache.set(cacheKey, {
|
||||
data: data.results,
|
||||
timestamp: Date.now()
|
||||
});
|
||||
|
||||
return data.results;
|
||||
}
|
||||
|
||||
clear() {
|
||||
this.cache.clear();
|
||||
}
|
||||
}
|
||||
|
||||
const productCache = new ProductCache();
|
||||
```
|
||||
|
||||
### 防抖搜索
|
||||
|
||||
```javascript
|
||||
// 防抖函数避免频繁请求
|
||||
function debounce(func, wait) {
|
||||
let timeout;
|
||||
return function executedFunction(...args) {
|
||||
const later = () => {
|
||||
clearTimeout(timeout);
|
||||
func(...args);
|
||||
};
|
||||
clearTimeout(timeout);
|
||||
timeout = setTimeout(later, wait);
|
||||
};
|
||||
}
|
||||
|
||||
const searchProducts = debounce(async (query) => {
|
||||
const response = await fetch(
|
||||
`/api/v1/products/quick/?search=${encodeURIComponent(query)}&limit=10`,
|
||||
{
|
||||
headers: {
|
||||
'Authorization': `Bearer ${token}`
|
||||
}
|
||||
}
|
||||
);
|
||||
const data = await response.json();
|
||||
updateSearchResults(data.results);
|
||||
}, 300);
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 常见问题
|
||||
|
||||
### Q: 为什么只返回 id 和 name？
|
||||
|
||||
**A**: 这是一个轻量级接口，专门为下拉框和自动完成设计。只返回必要的字段可以：
|
||||
- 减少数据传输量
|
||||
- 提高响应速度
|
||||
- 降低服务器负载
|
||||
|
||||
如果需要完整的产品信息，请使用完整的产品 API。
|
||||
|
||||
### Q: 搜索是否区分大小写？
|
||||
|
||||
**A**: 不区分。搜索使用 `icontains` 查询，对大小写不敏感。
|
||||
|
||||
### Q: 最多能返回多少条数据？
|
||||
|
||||
**A**: 建议使用 `limit` 参数限制返回数量。对于下拉框，建议 `limit=100`；对于自动完成，建议 `limit=10`。
|
||||
|
||||
### Q: 如何实现"加载更多"功能？
|
||||
|
||||
**A**: 使用 `offset` 参数进行分页。每次增加 `offset` 的值来获取下一页数据。
|
||||
|
||||
```javascript
|
||||
let offset = 0;
|
||||
const limit = 20;
|
||||
|
||||
async function loadMore() {
|
||||
const response = await fetch(
|
||||
`/api/v1/products/quick/?limit=${limit}&offset=${offset}`,
|
||||
{ headers: { 'Authorization': `Bearer ${token}` } }
|
||||
);
|
||||
const data = await response.json();
|
||||
|
||||
appendProducts(data.results);
|
||||
offset += limit;
|
||||
|
||||
// 检查是否还有更多数据
|
||||
return data.next !== null;
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 测试
|
||||
|
||||

|
||||
## 代码实现
|
||||
|
||||
### ViewSet 实现
|
||||
|
||||
```python
|
||||
class ProductQuickViewSet(viewsets.GenericViewSet):
|
||||
"""产品快速查询接口"""
|
||||
queryset = Product.objects.all()
|
||||
permission_classes = [IsAuthenticated]
|
||||
pagination_class = LimitOffsetPagination
|
||||
filter_backends = [DjangoFilterBackend, filters.SearchFilter]
|
||||
search_fields = ['name']
|
||||
|
||||
def list(self, request, *args, **kwargs):
|
||||
# 只返回 id 和 name
|
||||
queryset = self.filter_queryset(self.get_queryset())
|
||||
page = self.paginate_queryset(queryset)
|
||||
|
||||
if page is not None:
|
||||
data = [{'id': p.id, 'name': p.name} for p in page]
|
||||
return self.get_paginated_response(data)
|
||||
|
||||
data = [{'id': p.id, 'name': p.name} for p in queryset]
|
||||
return Response({'count': len(data), 'results': data})
|
||||
```
|
||||
|
||||
### URL 注册
|
||||
|
||||
```python
|
||||
# api_v1/urls.py
|
||||
from .views.products import ProductQuickViewSet
|
||||
|
||||
main_router.register(r'products/quick', ProductQuickViewSet, basename='product-quick')
|
||||
```
|
||||
|
||||

|
||||
|
||||

|
||||
|
||||
## 使用示例
|
||||
|
||||
### Python
|
||||
|
||||
```python
|
||||
import requests
|
||||
|
||||
headers = {"Authorization": f"Bearer {token}"}
|
||||
response = requests.get(
|
||||
"http://localhost:8000/api/v1/products/quick/?search=布料&limit=10",
|
||||
headers=headers
|
||||
)
|
||||
products = response.json()['results']
|
||||
```
|
||||
|
||||
### JavaScript
|
||||
|
||||
```javascript
|
||||
const response = await fetch('/api/v1/products/quick/?search=布料&limit=10', {
|
||||
headers: { 'Authorization': `Bearer ${token}` }
|
||||
});
|
||||
const { results } = await response.json();
|
||||
```
|
||||
|
||||
### curl
|
||||
|
||||
```bash
|
||||
curl -X GET "http://localhost:8000/api/v1/products/quick/?search=布料&limit=10" \
|
||||
-H "Authorization: Bearer YOUR_TOKEN"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 前端集成
|
||||
|
||||
### React Select 示例
|
||||
|
||||
```jsx
|
||||
function ProductSelect() {
|
||||
const [products, setProducts] = useState([]);
|
||||
|
||||
useEffect(() => {
|
||||
fetch('/api/v1/products/quick/?limit=100', {
|
||||
headers: { 'Authorization': `Bearer ${token}` }
|
||||
})
|
||||
.then(res => res.json())
|
||||
.then(data => setProducts(data.results));
|
||||
}, []);
|
||||
|
||||
return (
|
||||
<select>
|
||||
{products.map(p => (
|
||||
<option key={p.id} value={p.id}>{p.name}</option>
|
||||
))}
|
||||
</select>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### Vue AutoComplete 示例
|
||||
|
||||
```vue
|
||||
<el-autocomplete
|
||||
v-model="search"
|
||||
:fetch-suggestions="queryProducts"
|
||||
@select="handleSelect"
|
||||
/>
|
||||
|
||||
<script setup>
|
||||
const queryProducts = async (query, cb) => {
|
||||
const url = `/api/v1/products/quick/?search=${query}&limit=10`;
|
||||
const res = await fetch(url, {
|
||||
headers: { 'Authorization': `Bearer ${token}` }
|
||||
});
|
||||
const data = await res.json();
|
||||
cb(data.results.map(p => ({ value: p.name, id: p.id })));
|
||||
};
|
||||
</script>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 性能考虑
|
||||
|
||||
1. **只查询必要字段**: 只返回 id 和 name，减少数据传输
|
||||
2. **支持分页**: 避免一次性加载大量数据
|
||||
3. **模糊搜索**: 使用数据库索引优化查询
|
||||
4. **前端缓存**: 建议缓存常用数据5分钟
|
||||
5. **防抖搜索**: 建议搜索输入延迟300ms
|
||||

|
||||
## 扩展建议
|
||||
|
||||
### 未来可能的扩展
|
||||
|
||||
1. **增加更多字段**: 如需要，可添加 `color`, `spec` 等字段
|
||||
2. **批量查询**: 支持通过 ID 列表批量查询产品
|
||||
3. **最近使用**: 记录用户最近选择的产品
|
||||
4. **推荐功能**: 根据历史记录推荐产品
|
||||
5. **多语言支持**: 支持产品名称国际化
|
||||
|
||||
### 类似接口
|
||||
|
||||
可以参考此模式为其他实体创建类似接口：
|
||||
- `CustomerQuickViewSet` - 客户快速查询
|
||||
- `WarehouseQuickViewSet` - 仓库快速查询
|
||||
- `EmployeeQuickViewSet` - 员工快速查询
|
||||
|
||||
