Webpack 5 Dev Server 代理似乎被忽略

Question

首先，这在 webpack 4 中运行良好。升级到 webpack 5 后，除了开发服务器代理外，一切似乎都很好。就像我输入的任何值都被完全忽略了一样。

我得到的只是以下错误 尝试代理时出错：localhost:3006/api/configuration

我也曾经从开发服务器注销过，但似乎也被忽略了。 EG "从 localhost:3006 代理到 localhost:5050

版本：

webpack - 5.65.0
webpack-dev-server - 4.7.2
webpack-cli - 4.9.1

const common = require('./webpack.common.js');

我不确定 webpack 4，但我认为您需要使用 changeOrigin，因为您在服务器和 webpack 开发服务器中使用默认端口。

如果您的服务器中没有有效的 SSL，您可能还需要设置 secure: false。

proxy: {
  '/api': {
    target: 'https://localhost:5050',
    secure: false,
    changeOrigin: true,
  },
},
