react项目实战学习笔记-学习16-注册逻辑 跨域解决

修改

webpackDevServer.config.js

proxy: {
      '/api': {
        target: '', // 后台服务地址以及端口号
        changeOrigin: true, //是否跨域
        pathRewrite: { '^/api': '/' }
      }
    },

注册逻辑

          message.success(res.message);
          // 跳到登录页
           setTimeout(()=>navigate('/login'), 1500)
