我正在使用 react(MERN stack) 創建一個簡單的待辦事項應用程序。當我嘗試同時使用 axios 和 setState 調用 get API 時出現上述警告。我已經通過堆棧溢出的其他線程解決了同樣的問題，但沒有一個真正有用。我什至試過弄亂“isMounted”變量。下面是我的代碼...export default class App extends React.Component{  _isMounted = false;  constructor(props){    super(props);    this.state = {list:[], itemCounter: 0};    this.addItem = this.addItem.bind(this);    this.handleDone = this.handleDone.bind(this);    this.componentDidMount = this.componentDidMount(this);  }    componentDidMount(){    this._isMounted = true;    axios.get(`http://localhost:8000/todo/api/`)      .then(res => {        if(this._isMounted){          const list = res.data;          const unDoneList = list.filter(task => task.done === false)          this.setState({ list: list, itemCounter: unDoneList.length });      }});  }  componentWillUnmount() {    this._isMounted = false;  }  addItem(val) {    axios.post('http://localhost:8000/todo/api/task/', { data: val })    .then(res => {      const itemCounter = this.state.counter + 1;      const updatedList = this.state.list;      updatedList.push({ data: val, done: false });      console.log(res);      console.log(res.data);      this.setState({ list: updatedList, itemCounter: itemCounter });    })  }    handleDone(item){    console.log(item._id)    axios.post(`http://localhost:8000/todo/api/delete/${item._id}`)    .then(() => console.log("Item Deleted."));    let updatedList = this.state.list;    updatedList.forEach(task => {      if(task.id === item.id ){        task.done = true;      }    });        const itemCounter = this.state.itemCounter - 1;    this.setState({ list: updatedList, itemCounter: itemCounter });  }作為參考，我已經在 GitHub 上上傳了我的整個項目： https: //github.com/mohnishm/Todo-App-in-React 如何擺脫這個警告？
