Such a problem. i need to skip the request when there is no user.
i tried doing this and that

这真是个问题。当没有用户时，我需要跳过该请求。我试着做这个做那个


const { data: carts = [] as ICart[], isFetching } =
 api.useGetCartProductsQuery(user.id, { skip: !user})

const { data: carts = [] as ICart[], isFetching } =
 api.useGetCartProductsQuery(user.id, { skip: true })

but every time I get an error

但每次我出错


Unhandled Runtime Error TypeError: Cannot read properties of null (reading 'id')

Source
src\app\dashboard\Dashboard.tsx (35:35) @ id

  33 | 
  34 |  const { isLoading, data: carts = [] as ICart[] } =
> 35 |      api.useGetCartProductsQuery(user.id, { skip: true })

Tell me how to make it work correctly.

告诉我怎么才能让它正常工作。

You are on the same time still trying to access user.id - this is JavaScript code that is executed outside of RTK Query, which you have written:

同时，您仍在尝试访问user.id-这是在RTK查询之外执行的JavaScript代码，您已经编写了：


api.useGetCartProductsQuery(user.id, { skip: !user })

You could try to get around that by providing some kind or default:

您可以尝试通过提供某种类型或默认设置来绕过这一点：


api.useGetCartProductsQuery(user ? user.id : undefined, { skip: !user })

but that is kinda unsatisfying to read.

但这读起来有点令人不满意。


Instead you can use the skipToken (exported from RTK Query)

您可以使用skipToken(从RTK查询中导出)


api.useGetCartProductsQuery(user ? user.id : skipToken)
