在electron-vue中配置跨域代理

No 'Access-Control-Allow-Origin' header is present on the requested resource. 跨域问题！

     {
        contentBase: path.join(__dirname, '../'),
        quiet: true,
        proxy: {
          '/seller': {
            // 请求的目标服务器地址
            target: 'http://192.168.3.107:8080',
            // 设置允许跨域
            changeOrigin: true,
            // 重写路径
            pathRewrite: {
              '^/seller': '/seller'
            },
            headers: {
              referer: ''
            }
          }
        },
        before (app, ctx) {
          app.use(hotMiddleware)
          ctx.middleware.waitUntilValid(() => {
            resolve()
          })
        }
      }
