let order = req.query.order || 'asc'
This line of code sets a variable called "order" to the value of the query parameter "order" from the incoming request, or 'asc' if no value is provided for the "order" parameter. This is typically used in sorting results in ascending or descending order.
page = req.query.page || 1
根据您提供的代码片段,您想要获取一个名为"page"的查询参数的值,如果该参数不存在,则默认值为1。
在大多数编程语言中,这可以通过以下逻辑来实现:
```javascript
var page = req.query.page || 1;
```
这行代码使用了逻辑或(`||`)运算符。它首先尝试获取`req.query.page`的值,如果该值存在(即不为假值),则将其赋给`page`变量;否则,将默认值1赋给`page`变量。
请注意,具体的实现方式可能因编程语言或框架而异。上述代码仅为示例,请根据您的实际情况进行相应的修改。
