javascript - 如何传递从服务器返回的数据，然后将返回的数据转移到另一个路由？

Question

Hi, I am new to react. I made a server call and then successfully got a response. Now, I am trying to pass the same response to another route and display there. I am unable to understand, how do we do this in react, like in Ember there's a method this.transitionTo('routepath', {data}) and then this data is available in routepath in models(params). How is this possible in react? I am bound to not using any Redux or any other state container. My code is below:

import React, { Component } from 'react'
import axios from 'axios'

class Ernform extends Component {
  constructor (props) {
    super();
    this.state = {
        category: '',
        zipcode: '',
        age: '',
        gender: '',
        key: '',
        data: null
    };
  }

  onChange = (e) => {
    this.setState({ [e.target.name]: e.target.value });
  }

  getPolicies = (e) => {
    e.preventDefault();
    const { category, zipcode, age, gender, key } = this.state;
    axios.post(`http://localhost:4000/api/v1/quote`, { category, zipcode, age, gender, key })
      .then(response => {
        this.setState({data: response}); // I am setting response from server to the state property data
        this.props.history.push('/details', {data: this.state.data})//I am trying to pass the data and trying to transition here.      
      });
  }

    render() {
    const { category, zipcode, age, gender } = this.state;
        return (
            <div>
                <form onSubmit={this.getPolicies}>
                    <label>
                        Category: <input type="text" name="category" value={category} onChange={this.onChange}/>
                    </label>
                    <label>
                        Zipcode: <input type="text" name="zipcode" value={zipcode} onChange={this.onChange}/>
                    </label>
                    <label>
                        Age: <input type="text" name="age" value={age} onChange={this.onChange}/>
                    </label>
                    <label>
                        Gender: <input type="text" name="gender" value={gender} onChange={this.onChange}/>
                    </label>
          <button className="btn btn-primary btn-lg lead" type="submit">Get Policies</button>
                </form>
            </div>
        );
    }
}

export default Ernform

My router is this:

import React from 'react'
import { Switch, Route } from 'react-router-dom'
import Ernform from './Ernform';
import Ernentry from './Ernentry'
import Erndetails from './Erndetails';

const Routing = () => (
    <main>
      <Switch>
        <Route exact path='/' component={Ernentry}/>
        <Route path='/auto' component={Ernform}/>
        <Route path='/life' component={Ernform}/>
        <Route path='/details' component={Erndetails}/> // added this route.
      </Switch>
    </main>
  )

  export default Routing

My details route component is this

import React, { Component } from 'react'


class Erndetails extends Component {
    constructor(props) { // Where would i get the data i transition with from that route.
        console.log(props);
        super()
    }
    render() {
        return (
            <div></div>
        )
    }
}

export default Erndetails

Thanks a lot guys in Advance.

Answer 1

有两种解决方案可以解决您的问题，

I) 第一个解决方案是以这种方式将推送对象中的数据与路由一起传递， this.props.history.push({
pathname: '/details',
state: { detail: response.data }
})

而不是你传递的内容。

在您的详细信息路由组件中，您可以使用 props.location.state.detail 获取数据在你的构造函数中或 this.props.location.state.detail在 componentDidMount 生命周期中。

2) 第二种解决方案是使用 localStorage.setItem('token', data) 将其存储在本地存储中然后使用 localStorage.getItem('token') 访问它
