如何禁用 RTK 查询自动请求提取？

Question

当我从 createApi 应用自动生成的挂钩时。该挂钩向服务器发出自动请求，但我只需要在特定条件下发出该请求。我尝试按照Redux的文档来实现：(https://redux-toolkit.js.org/rtk-query/usage/conditional-fetching)，但是没有成功。

我的实现：(src/features/posts/PostList.js)

import React, { useState } from 'react'
import { useGetPostsQuery } from '../api/apiSlice'

const PostExcerpt = ({ post }) => {
    return (
        <div>
            <p>{post.postText}</p>
            <p>
                <small>{post.author}</small>
            </p>
        </div>
    )
}

export const PostList = () => {
    const [skip, setSkip] = useState(true)
    const { data: posts = [], isLoading, isSuccess, isError, error } = useGetPostsQuery({ skip })

    let content

    if (isLoading) {
        content = <h3>Posts Loading ...</h3>
    } else if (isSuccess) {
        content = posts.map(post => <PostExcerpt key={post.id} post={post} />)
    } else if (isError) {
        content = (
            <div>
                <h3>Error happened</h3>
                <p>
                    <small>{error.toString()}</small>
                </p>
            </div>
        )
    }

    return (
        <div style={{ border: '2px solid red' }}>
            <h2>Posts:</h2>
            <button onClick={() => setSkip(prev => !prev)}>Fetch it</button>
            {content}
        </div>
    )
}

根据 Redux Toolkit RTK 查询文档，我应该使用一个带有布尔值跳过属性的对象作为自动生成挂钩的参数。我做了，但没有成功。它一直在向服务器发出请求。那么，我做错了什么？

apiSlice 看起来像：(src/features/api/apiSlice.js )

import { createApi, fetchBaseQuery } from '@reduxjs/toolkit/query/react'

// Define our single API slice object
export const apiSlice = createApi({
    // The cache reducer expects to be added at `state.api` (already default - this is optional)
    reducerPath: 'api',
    // All of our requests will have URLs starting with '/fakeApi'
    baseQuery: fetchBaseQuery({ baseUrl: '/fakeApi' }),
    // The "endpoints" represent operations and requests for this server
    endpoints: builder => ({
        // The `getPosts` endpoint is a "query" operation that returns data
        getPosts: builder.query({
            // The URL for the request is '/fakeApi/posts'
            query: () => '/posts',
        }),
        addNewPost: builder.mutation({
            query: initialPost => ({
                url: '/posts',
                method: 'POST',
                body: initialPost,
            }),
        }),
    }),
})

// Export the auto-generated hook for the `getPosts` query endpoint
export const { useGetPostsQuery, useAddNewPostMutation } = apiSlice

您也可以在 GitHub 上查看此代码。 GitHub link:https://github.com/AlexKor-5/Redux_Mock_Service_Worker/tree/bd593191dce8c13982ffa2cdb946046d6eb26941

Answer 1

选项总是第二个参数 - 你需要做

useGetPostsQuery(undefined, { skip })

Answer 2

您将 'skip' 作为查询参数传递，但它是一个选项，因此它必须在挂钩的第二个参数中。如果您的查询没有参数，那么您可以传递 'null' 或 'undefined'
