/addCart.html?skuId=42&skuNum=1&sourceType=query的参数接受方式
时间: 2023-11-25 12:33:59 浏览: 116
该URL中的参数是通过查询字符串的方式进行传递的,即使用问号"?"将参数与URL进行分隔,参数之间使用"&"符号进行分隔。例如,skuId=42表示商品的ID为42,skuNum=1表示购买数量为1,sourceType=query表示来源类型为查询。在服务器端,可以通过解析查询字符串来获取这些参数的值。

/addCart.html?skuId=42&skuNum=1&sourceType=query的参数怎么接收
如果你正在使用后端框架,比如Java的Spring或者Python的Django,那么可以通过以下方式接收该请求参数:
Java Spring:
```java
@RequestMapping(value = "/addCart.html", method = RequestMethod.GET)
public String addToCart(@RequestParam("skuId") String skuId, @RequestParam("skuNum") int skuNum, @RequestParam("sourceType") String sourceType) {
// 处理添加购物车的逻辑
return "success";
}
```
Python Django:
```python
def add_to_cart(request):
sku_id = request.GET.get('skuId')
sku_num = request.GET.get('skuNum')
source_type = request.GET.get('sourceType')
# 处理添加购物车的逻辑
return HttpResponse('success')
```
如果你正在使用纯粹的JavaScript或者jQuery进行开发,可以通过以下方式获取请求参数:
```javascript
var urlParams = new URLSearchParams(window.location.search);
var skuId = urlParams.get('skuId');
var skuNum = urlParams.get('skuNum');
var sourceType = urlParams.get('sourceType');
// 处理添加购物车的逻辑
```
注意:URLSearchParams是ES6中的新特性,如果需要在低版本浏览器中使用,需要引入polyfill。
找出这串代码的错误并给出正确答案<!DOCTYPE html> <?php $products = array( array("id"=>"1","name"=>"可可芭蕾","price"=>13.00), array("id"=>"2","name"=>"阿华田","price"=>17.00), array("id"=>"3","name"=>"冰淇淋红茶","price"=>8.00), array("id"=>"4","name"=>"百香三重奏","price"=>15.00) ); session_start(); $sum = 0; if(! empty($_SESSION['cart'])) { $order = $_SESSION['cart']; $sum = array_sum(array_column($order, "num")); } ?> <html> <head> <meta charset="UTF-8"> <link rel="stylesheet" type="text/css" href="css/style.css" /> <title>PHP购物</title> </head> <body> <div> <h1>商品列表</h1> <hr> <table> <tr> <th>商品名</th> <th>售价</th> <th>购物车</th> </tr> <?php foreach ($products as $key => $value);?> <tr> <td><?php echo $value['name'];?></td> <td>¥<?php echo $value['price'];?></td> <td><a class="btn" href="addCart.php?upd=add&id=<?php echo $value['id'];?>&name=<?php echo $value['name'];?> &price=<?php echo $value['price'];?>">+</a></td> </tr> <?php endforeach;?> </table> <div> <a href="addCart.php?upd=cart">我的购物车</a> <span><?php echo $sum;?></span> </div> </div> </body> </html>
这段代码的错误是在foreach循环中的分号(;)应该是冒号(:),正确答案如下所示:
<!DOCTYPE html>
<?php
$products = array(
array("id"=>"1","name"=>"可可芭蕾","price"=>13.00),
array("id"=>"2","name"=>"阿华田","price"=>17.00),
array("id"=>"3","name"=>"冰淇淋红茶","price"=>8.00),
array("id"=>"4","name"=>"百香三重奏","price"=>15.00)
);
session_start();
$sum = 0;
if(! empty($_SESSION['cart'])) {
$order = $_SESSION['cart'];
$sum = array_sum(array_column($order, "num"));
}
?>
<html>
<head>
