我本地开发环境项目启动在3000端口，从3200端口请求当前项目的接口时，响应头返回的access-control-allow-origin值会多一个，变成
*, http://localhost:3000 而导致跨域问题，实际应该只需要返回*

开发服务器的配置如下：

server: {
    port,
    headers: {
      'Access-Control-Allow-Origin': '*',
    },
    proxy: {
      [VUE_APP_BASE_API ?? '']: {
        target: VUE_APP_TARGET_URL,
        changeOrigin: true,
        pathRewrite: {
          [`^${VUE_APP_BASE_API}`]: VUE_APP_TARGET_BASE_API,
        },
      },
    },
  },

尝试过将headers的配置去掉，结果一样
