部署到文件夹后反应空白页

Posted 2021-04-11

我有一个反应应用程序： http：// we ****。com / buzz /

上面的url显示它已部署在buzz文件夹下。

它只displays blank page ，浏览器中no console error 。

我已经在package.json中设置了homepage变量，所有的网址似乎都没问题。

有人可以让我知道这个问题。

我的package.json文件是：

{
  "name": "buzz",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^16.8.6",
    "react-dom": "^16.8.6",
    "react-router-dom": "^5.0.1",
    "react-scripts": "3.0.1"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "homepage": "http://we****.com/buzz/",
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

我的路线档案::

import React, { Component } from 'react';
import { BrowserRouter, Route, Switch } from "react-router-dom";

import HomeComponent from '../Components/Home';
import LoginComponent from '../Components/Login';
import SignupComponent from '../Components/Signup';
import MyStoriesComponent from '../Components/Story/MyStories';
import AddStoryComponent from '../Components/Story/AddStory';

export default class Routes extends Component {
    render() {
        return (
            <BrowserRouter>
                <Switch>
                    <Route exact path="/" component={HomeComponent} />
                    <Route exact path="/login" component={LoginComponent} />
                    <Route exact path="/signup" component={SignupComponent} />
                    <Route exact path="/mystories" component={MyStoriesComponent} />
                    <Route exact path="/addstory" component={AddStoryComponent} />
                    {/*<Route exact path="/listPartnerAccount/:id" component={ListPartnerAccount} />*/}
                </Switch>
            </BrowserRouter>
        );
    }
}

答案

我通过做两件事解决了这个问题：

1）在package.json文件中设置以下代码

"homepage": "http://we****.com/buzz/" 

2）在路由文件中设置BrowserRouter中的basename：

export default class Routes extends Component {
    render() {
        return (
            <BrowserRouter basename={'/buzz'}>
                <Switch>
                    <Route exact path="/" component={HomeComponent} />
                    <Route exact path="/login" component={LoginComponent} />
                    <Route exact path="/signup" component={SignupComponent} />
                    <Route exact path="/mystories" component={MyStoriesComponent} />
                    <Route exact path="/addstory" component={AddStoryComponent} />
                    {/*<Route exact path="/listPartnerAccount/:id" component={ListPartnerAccount} />*/}
                </Switch>
            </BrowserRouter>
        );
    }
}

请注意，只有在package.json文件中设置主页对我不起作用，这是上述2个步骤的组合对我有用。

另一答案

如果您将构建文件上传到该目录（http：//*****.com/buzz/），这应该可以正常工作。

请先在package.json上添加主页后确认您构建应用程序。 该命令是（纱线运行构建或纱线构建），之后将文件从构建目录上传到您想要的位置。
