react读取静态文件

Posted 2021-02-12 zealousness

react中，使用发送请求的方式把static文件夹中的前端可访问的静态文件读取成字符串：

import React, { Component } from ‘react‘;

import { getRequestHeaders } from ‘../setupAjaxHeaders‘;
import HyperDown from ‘hyperdown‘;

import ‘./ReadMePage.css‘;


class ReadMePage extends Component {
    constructor(props){
        super(props);

        this.state={
            readmehtml:undefined,
        };
    }

   
    render(){
        
        const getArtifactRequest = new Request(require(‘../static/readme.md‘), {
            method: ‘GET‘,
            headers: new Headers(getRequestHeaders(document.cookie))
        });


        fetch(getArtifactRequest).then((response) => {
            return response.text()
        }).then((text) => {
            const parser=new HyperDown;
            this.state.readmeHtml=parser.makeHtml(text);
            this.setState({
                readmeHtml:parser.makeHtml(text),
            });
            return <div id="readMeBody" dangerouslySetInnerHTML={{__html:this.state.readmeHtml}}></div>;
        });
return <div id="readMeBody" dangerouslySetInnerHTML={{__html:this.state.readmeHtml}}></div>;

    }

}


export default ReadMePage;

 

注意，要保存代码中动态生成的结果，必须在构造函数中定义 this.state={resultname:undefined, } 并在生成结果时调用this.setstate({ resultname:result, })，然后后续调用的时候使用this.state.resultname

 

注意，request获取response之后，response.text()需要通过return再then才能获取到，直接使用是获取不到的
