提取返回我自己的index.html的html源 [英] Fetch returns html source of the my own index.html

问题描述

我正在尝试在react-create-app服务器(localhost:3000)中使用fetch从我的apache(localhost:80)获取静态.json文件，但是它返回我的react index.html文件的源！

I am trying to use fetch in an react-create-app server(localhost:3000) to get a static .json file from my apache(localhost:80) but it returns source of my react index.html file!

指定端口号会导致网络错误"

Specifying port number results in "networking error"

const that=this;
fetch("localhost/myapp/data/structure.json").then((res)=> {return res.text()})
                .then(((data)=>{that.setState({structure: data})})).catch((e)=>{alert(e.toString())});

推荐答案

从根本上说，问题在于使react-create-app与本地服务器一起使用，本指南 https://daveceddia.com/create-react-app-express-backend/

Downright the problem comes to making react-create-app work with a local server which is explained in this guide https://daveceddia.com/create-react-app-express-backend/

简而言之，我需要在我的package.json中放置一个代理属性，其值等于本地服务器的地址.就我而言:

In short I needed to put a proxy property with the value equal to address of my local server in my package.json. In my case:

  "proxy": "http://localhost:80"
