我有一個大問題，也許它不是那么大，但因為它我幾乎沒有睡 24 小時。我幾乎沒有完成這個切片，但是現在，當我提交資料時，我只得到自動設定的 id ..
所以，成為清除。我有一個技能組件，其中我有 2 個輸入表單和一個按鈕，我需要從兩個輸入中檢索資料，然后，當它們被提交時，被提取并保存在持久化器中。到現在一切都很好，我引入資料，發布請求成功，但是，有效負載只有 mirage js 自動生成的 id。但我需要一個包含型別、范圍道具及其值的陣列，并且每次我單擊按鈕，應填充此物件的陣列。
這是我的組件：
在這里我提交資料：
正如你所看到的，只有 id 存在在那里..我被卡住了......
以上是我提交資料6次時的串列..只有id，我不知道可能是什么問題，請幫助..
技能部分：
import React, { useState,useEffect } from 'react'
import { Formik, Form, useFormik } from 'formik'
import * as Yup from 'yup'
import FormikControl from '../Form/FormikControl'
import DisplayFormikState from '../Form/DisplayFormikState.js'
import { useDispatch, useSelector } from 'react-redux'
import { addNewSkill,fetchSkills,selectSkill } from '../../features/skills/skillSlice'
const Skills = () =>{
const dispatch = useDispatch();
// const [skill, setSkills] = useState({
// name: '',
// range: null
// });
useEffect(()=>{
dispatch(fetchSkills());
},[dispatch])
// const userInfo = useSelector(selectSkill);
// const skillList = useSelector(state => state.skillState.skills)

// As you see we're getting the whole state

const list = useSelector(state => state.list);
const formik = useFormik({

return(
<>
<section id="skills">

export default Skills
切片機：
export const fetchSkills = createAsyncThunk(
'skills/fetchSkills',
async (_, {rejectWithValue}) => {
try{
const response = await fetch('/api/skills',{
method:'GET',
})
// console.log(response)
if(!response.ok){
throw new Error ('Server Error!');
}
const data = await response.json();
// console.log(data)
return data;
} catch(error){
return rejectWithValue(error.message);
}
}
);
const setError = (state, action) => {
state.status = 'rejected';
state.error = action.payload;
}
export const addNewSkill = createAsyncThunk(
'skills/addNewSkill',
async (skillData,{rejectWithValue,dispatch}) =>{
const {skillName,skillRange} = skillData
try{
const skill = {
name: skillName,
range: skillRange,
};
const response = await fetch('/api/skills',{
method:'POST',
headers:{
'Content-name' : 'application/json',
},
body: JSON.stringify(skill)
});
if(!response.ok){
throw new Error('Can\'t add skill. Server error')
}
const data = await response.json();
dispatch(setSkill(data))
}catch(error){
return rejectWithValue(error.message);
}
}
)
export const skillSlice = createSlice({
name: "skills",
initialState: {
skills:[],
status: null,
error: null
},
reducers: {
setSkill: (state, action) => {
// console.log("action", action.payload);
// state.name = action.payload?.name;
// state.range = action.payload?.range;
state.skills.push(action.payload);
// localStorage.setItem(state.name,action.payload.range)
},
},
extraReducers:{
[fetchSkills.pending]:(state,action)=>{
state.status = 'loading';
state.error = null;
},
[fetchSkills.fulfilled]:(state,action)=>{
state.status = 'resolved';
state.name = action.payload;
},
[fetchSkills.rejected]: setError,
}
});
const { setSkill } = skillSlice.actions;
export const selectSkill = (state) => state?.skill;
export default skillSlice.reducer;
我在其中模擬 api 的 Miragejs 服務器：
import { createServer,Model } from "miragejs"
export const makeServer =({ environment = 'test' } = {}) => {
let server = createServer({
environment,
models: {
educations: Model,
skills:Model
},
seeds(server) {
server.create("education", { date: 2001, title: "Title 0", text: "Elit voluptate ad nostrud laboris. Elit incididunt mollit enim enim id id laboris dolore et et mollit. Mollit adipisicing ullamco exercitation ullamco proident aute enim nisi. Dolore eu fugiat consectetur nulla sunt Lorem ex ad. Anim eiusmod do tempor fugiat minim do aliqua amet ex dolore velit.\r\n" });
server.create("education", { date: 2000, title: "Title 1", text: "Et irure culpa ad proident labore excepteur elit dolore. Quis commodo elit culpa eiusmod dolor proident non commodo excepteur aute duis duis eu fugiat. Eu duis occaecat nulla eiusmod non esse cillum est aute elit amet cillum commodo.\r\n" });
server.create("education", { date: 2012, title: "Title 2", text: "Labore esse tempor nisi non mollit enim elit ullamco veniam elit duis nostrud. Enim pariatur ullamco dolor eu sunt ad velit aute eiusmod aliquip voluptate. Velit magna labore eiusmod eiusmod labore amet eiusmod. In duis eiusmod commodo duis. Exercitation Lorem sint do aliquip veniam duis elit quis culpa irure quis nulla. Reprehenderit fugiat amet sint commodo ex.\r\n" });
},
routes() {
//this.namespace = 'api/educations';
this.get('api/educations', (schema, request) => {
return schema.educations.all();
},
{ timing: 1000 });
// this.namespace = 'api/skills';
this.get('api/skills', (schema, request) => {
return schema.skills.all();
},
{ timing: 1000 });
this.post('api/skills', (schema, request) => {
let attrs = JSON.parse(request.requestBody);
return schema.skills.create(attrs);
},
{ timing: 1000 });
},
})
return server;
}
和根減速器：
const rootReducer = combineReducers({
visibilityState: toggleButtonReducer,
educationState: educationReducer,
skills : skillReducer
})
uj5u.com熱心網友回復：
您正在使用字串值調度 addNewSkill，而您在 thunk 中間件中期待一個物件。
dispatch(addNewSkill(type));
dispatch(addNewSkill(range));
export const addNewSkill = createAsyncThunk(
'skills/addNewSkill',
async (skillData,{rejectWithValue,dispatch}) =>{
const {skillName,skillRange} = skillData
// skillData is not an object but a string
})
你應該用這個替換你的handleAction。
const handleAction = (e) => {
e.preventDefault()
dispatch(addNewSkill({skillName: type, skillRange: range}));
setType('');
setRange('');
}
