React-Router超过了最大更新深度

Question

当我尝试在反应路线中检查授权或无授权时出现此错误

错误： “超过最大更新深度。当组件重复调用componentWillUpdate或componentDidUpdate内部的setState时，可能会发生这种情况。React限制了嵌套更新的数量，以防止无限循环”

App.js

 render() {
    return (
       <View style={styles.container1}>      
      <ScrollView>
      <View style={styles.container}>        
         <View style={styles.SectionStyle}>       
                <Image source={require('../assets/padlock.png')} style={styles.ImageStyle} />       
                 <TextInput
                    style={{flex:1}}
                    placeholder="Current Password"
                    underlineColorAndroid="transparent"

         </Auth>

NonAuth.js

import React from 'react'
import { Redirect } from 'react-router-dom'
import {
  connect,
} from 'react-redux'

const Auth = (props) => {
  console.log( props )
  return props.currentUser? props.children : <Redirect to={'/asks'}/>
}



const mapStateToProps = state => {
  return {currentUser:state.currentUser,}
}


export default connect(mapStateToProps)(Auth)
