React-Router 接收代碼

 import React from "react";
 import { Mutation } from "react-apollo";
 import { RouteComponentProps } from "react-router-dom";
 import { toast } from "react-toastify";
 import { LOG_USER_IN } from "../../sharedQueries.local";
 import { verifyPhone, verifyPhoneVariables } from "../../types/api";
 import VerifyPhonePresenter from "./VerifyPhonePresenter";
 import { VERIFY_PHONE } from "./VerifyPhoneQueries";

interface IState {
  verificationKey: string;
  phoneNumber:string; 
}

interface IProps extends RouteComponentProps<any> {}

class VerifyMutation extends Mutation<verifyPhone, 
verifyPhoneVariables> {}

class VerifyPhoneContainer extends React.Component<IProps, IState> {
 constructor(props: IProps) {
   super(props);
   if (!props.location.state) {
     props.history.push("/");
   }
   debugger;
   this.state = {
     phoneNumber: props.location.state.phone,
     verificationKey: ""
   };
 }

編譯失敗。 類型“{}”上不存在屬性“電話”。

請讓我知道為什么會發生錯誤。

我要用我的手機發短信和驗證。

但是，將電話號碼從上一頁移交到下一頁時，會出現以下錯誤。

我正在使用翻譯，因為我的英語不好。

我解決了

if (!props.location.state) {
         props.history.push("/");
       }
    const {
      location: { state }
    } = props;
    let phoneNumber = "";
    if (state) {
      phoneNumber = state.phone;
    } else {
      phoneNumber = "";
    }
    this.state = {
      phoneNumber,
      verificationKey: ""
    };
