部署heroku应用程序时出错(无法获取/)

标签: node.js reactjs heroku redux deployment

我在部署heroku应用程序时遇到问题(实际上,我一直在尝试部署它一个星期,以尝试找到的所有解决方案)。我根据需要设置了所有开发环境,但是似乎一旦部署了该应用程序,就不会再提供静态文件。部署应用程序后,将得到以下信息:无法获取/。在控制台中,我看到:无法加载资源:“服务器响应状态为404(未找到)”,以及:“拒绝加载图像'https://freshgear.herokuapp.com/favicon.ico',因为它违反了以下内容安全性策略指令:“ default-src'none'”。请注意,未明确设置'img-src',因此将'default-src'用作后备。”

任何帮助将不胜感激!

我将发布代码以提供一些上下文:

这就是我在server.js中拥有的

const DB = process.env.DATABASE.replace(   '<PASSWORD>',   process.env.DATABASE_PASSWORD );

mongoose   .connect(DB, {
    useNewUrlParser: true,
    useCreateIndex: true,
    useUnifiedTopology: true   })   .then(() => console.log('DB connection successful!'))   .catch(err => console.log(err));

这是我在app.js中拥有的:

if (process.env.NODE_ENV === 'production') {
  app.use(express.static(path.join(__dirname, 'client/build')), function (err) {
    if (err) {
      res.status(500).send(err)
    }
  });

  app.get('*', (req, res) => {
    res.sendFile(path.join(__dirname, 'client', 'build', 'index.html'), function (err) {
      if (err) {
        res.status(500).send(err)
      }
    })
  });
}

这是我的package.json文件:
