Question

我有一个应用程序，其中定义了所有父帖子并获取了调用。我正在尝试实现一种逻辑，如果有任何API向我发送401状态错误，则必须路由到首页。我尝试了该文件中的各种方法，但是我正在寻找的每个解决方案都无法正常工作。以下是我的Server.js代码：

import React, { Component } from "react";
import { Alert, AsyncStorage} from 'react-native';
import { RNS3} from "react-native-aws3";
import { NavigationActions, navigate, navigation } from "react-navigation";

export default class Server extends Component {
    constructor(props) {
    super(props);
    participantId = "";
    mobeToken = "";
    mobeToken1 = "";
    participantId1 = "";
    Url = "";
    urlAsync = "";
    AsyncStorage.getItem("participantId", (err, participantId) => {
      participantId1 = participantId;
    });
    AsyncStorage.getItem("mobeToken", (err, mobeToken) => {
      mobeToken1 = mobeToken;
    });
    AsyncStorage.getItem("URL", (err, Url) => {
      urlAsync = Url;
    });
    this.assignValues(participantId, mobeToken, Url);
  }

  assignValues(participantId, mobeToken, Url) {
    participantId1 = participantId;
    mobeToken1 = mobeToken;
    urlAsync = Url;
  }

  handleLog(){
    // const { navigate } = this.props.navigation;
    // navigation.navigate("PersonProfile");
    alert("hi");
    // AsyncStorage.setItem("session", "no", () => {
    //   this.props.navigation.dispatch(
    //     NavigationActions.reset({
    //       index: 0,
    //       actions: [NavigationActions.navigate({ routeName: "Home" })]
    //     })
    //   );
    // });
  };

  getRequest(url) {
    return fetch(urlAsync+"/api" + url , {
      method: 'GET',
      headers: {
        "mobeToken" : mobeToken1,
        "participantId": participantId1,
      } 
    })
      .then(response => response.json())
      .then(responseJson => {
        if (responseJson.error === 'authentication.error' ){
          this.handleLog();
        }
        return responseJson;
      })
      .catch(error => {
        console.log(error);
        // Alert.alert("", "Network connection issue. Please contact support");
        alert(error);
      });
  }

}

在此情况下，如果响应中出现错误，则必须在尝试实现导航逻辑的地方调用handleLog（）方法。让我知道该如何解决/或对此进行任何修复。

从全局server.js文件反应导航路由-定义“导航”错误
