reactjs - Firebase 电话认证 react js

Question

我正在尝试在 react js 中实现 firebase 电话身份验证，而不使用 firebase UI。我该怎么做？

代码

requestVerificationCode = () => {
    const { phoneNumber } = this.state;
    const appVerifier = new firebase.auth.RecaptchaVerifier(
      "recaptcha-container"
    );
    if (phoneNumber < 10) {
      this.setState({ error: true });
    } else {
      this.setState({ message: "Sending code ..." });

      firebase
        .auth()
        .signInWithPhoneNumber(phoneNumber, appVerifier)
        .then(confirmResult =>
          this.setState({ confirmResult, verifying: true })
        )
        .catch(error =>
          this.setState({
            message: `Sign In With Phone Number Error: ${error.message}`
          })
        );
    }
  };

错误

重要的部分是等待Vue JS中的componentDidMount()或mounted()，这样dom元素中包含"recaptcha-container" 已安装。

HTML

<input id="recaptcha-container" type="button" onClick="this.onClick" />

JS

componentDidMount () {
    window.recaptchaVerifier = new firebase.auth.RecaptchaVerifier("recaptcha-container",
    {
       size:"invisible"
        // other options
    });
}

onClick() {
    const phoneNumber = this.phone;
    const appVerifier = window.recaptchaVerifier;
    firebase
    .auth()
    .signInWithPhoneNumber(phoneNumber, appVerifier)
    .then(confirmResult => {
      // success
    })
    .catch(error => {
      // error
    });
}

如果您将用户重定向到 id="recaptcha-container" 所在的组件，那么 recaptcha 将正常工作但会在控制台中抛出与样式相关的错误，但那是因为它是想要在页面上有一个永久的位置。
