Question

我试图在我的RN应用中对redux使用反应导航。我有一个登录按钮，其按钮按下功能如下：

onButtonPress() {
    const { email, password } = this.props;
      this.props.loginUser({ email, password })
      .then(() => {
        this.props.navigate('Home');
      });
    }

loginUser是一个由redux调度的操作，但是按一下此按钮功能却在我的loginform组件中，该组件在主堆栈导航器中用作我的屏幕之一，并且我已经对其进行了测试以确保其正常工作，但是，无论何时添加导航功能，我都会不断收到此错误： undefined不是对象（评估'this.props.loginUser（{电子邮件：电子邮件，密码：密码}）。然后'）

但是，如果我在then语句之外有导航语句，则它可以工作。我尝试查看关于stackoverflow和github的其他问题，但没有找到有效的解决方案，有帮助吗？

这是我在登录日志（this.props）时得到的信息：

 Object {   "email": "n*********@gmail.com",   "emailChanged": [Function anonymous],   "error": "",   "loading": false,   "loginUser": [Function anonymous],   "navigation": Object {     "actions": Object {       "dismiss": [Function dismiss],       "goBack": [Function goBack],       "navigate": [Function navigate],       "pop": [Function pop],       "popToTop": [Function popToTop],       "push": [Function push],       "replace": [Function replace],       "reset": [Function reset],       "setParams": [Function setParams],     },     "addListener": [Function addListener],     "dangerouslyGetParent": [Function anonymous],     "dismiss": [Function anonymous],     "dispatch": [Function anonymous],     "getChildNavigation": [Function getChildNavigation],     "getParam": [Function anonymous],     "getScreenProps": [Function anonymous],     "goBack": [Function anonymous],     "isFocused": [Function isFocused],     "navigate": [Function anonymous],     "pop": [Function anonymous],     "popToTop": [Function anonymous],     "push": [Function anonymous],     "replace": [Function anonymous],     "reset": [Function anonymous],     "router": undefined,     "setParams": [Function anonymous],     "state": Object {       "key": "id-1532963235056-0",       "routeName": "Login",     },   },   "password": "******",   "passwordChanged": [Function anonymous],   "screenProps": undefined,   "signUpUser": [Function anonymous], }
