反應中的無效掛鈎調用。 我正在使用 class 組件

Question

當我導出應用程序時，我在最后一行的反應 class 組件中使用withTranslation() 。 但它給出了以下錯誤。

請檢查最后一行。

import React from 'react';
import { Input, Form, Row, Container, Card } from 'reactstrap';
import '../../../../node_modules/bootstrap/dist/css/bootstrap.css';
import baseUrl from '../../../base.js';
import ConfirmDlg from '../../Utils/Common/ConfirmDlg';
import { css } from 'react-emotion';
import { PropagateLoader } from 'react-spinners';
import i18next from 'i18next';
import i18n from '../../../i18n';
import { withTranslation } from 'react-i18next';
var request = require('superagent');

const override = css`
  display: block;
  margin: 0 auto;
  border-color: red;
`;

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      username: '',
      password: '',
      errorMessage: '',
      isConfirmDlgOpen: false,
      isLoading: false,
    };
  }

  render() {
    const { errorMessage, isConfirmDlgOpen, isLoading } = this.state;
    const { t } = this.props;
    return <div className="wrapper">{t('Accueil')}</div>;
  }
}

export default withTranslation()(MyComponent);

有沒有其他方法來處理同樣的事情。 我在其中使用翻譯的遺留應用程序

Answer 1

你應該像這樣使用它：

export default withTranslation(MyComponent);

Answer 2

使用此代碼運行並且沒有錯誤

import React from "react";
import { withTranslation } from "react-i18next";

class MyComponent extends React.Component {
  constructor(props: any) {
    super(props);
    this.state = {
      username: "",
      password: "",
      errorMessage: "",
      isConfirmDlgOpen: false,
      isLoading: false
    };
  }

  render() {
    const { t } = this.props;
    console.log(t);
    return <div className="wrapper">{t("xx")}</div>;
  }
}

export default withTranslation()(MyComponent);

可能是其他錯誤？
