修改好的路由代码，和测试用例代码，在下面，直接测试没法测试 redirect 后的 session。

作者你好，这里修订后 测试用例跑不通了。

我 clone 下来是可以正常跑通的，你可以自己对照下代码

[ifyour]

clone 的那个仓库还没添加 async await 😂

[MiYogurt]

测试好像没法这样去测试，这样测试要黑河测试，白盒可以换一种方式。代码推上去了。

修改图书中的示例代码

router.js

    router.get('/session1', async (ctx, next) => {
        ctx.flash_error({
            ss: 'some error'
        })
        ctx.body = ctx.session.flash

    })

    router.get('/session3', async (ctx, next) => {
        ctx.flash = {
            type: 'warning',
            message: {
                field: {
                    name: 'required'
                }
            }
        }
        ctx.request.flash('warning', {
            field: {
                name: 'required'
            }
        })
        ctx.body = ctx.session.flash
    })

msg-flash.test.js

  it('should GET /', () => {
    return app
      .httpRequest()
      .get('/')
      .expect('hi, flash')
      .expect(200)
  })

  it('should GET /session1', () => {
    const obj = {
      type: 'error',
      message: { ss: 'some error' }
    }

    return app
      .httpRequest()
      .get('/session1')
      .expect(
        JSON.stringify(obj)
      )
  })

  it('should GET /session3', () => {
    const obj = {
      type: 'warning',
      message: {
        field: {
          name: 'required'
        }
      }
    }

    return app
      .httpRequest()
      .get('/session3')
      .expect(
        JSON.stringify(obj)
      )
  })

@ifyour 用这个用例去测试，ctx.flash 是下一次请求的时候才能拿得到，第一次 用 ctx.session 里面去拿，这样测试就可以了。

[ifyour]

好的，感谢解答疑惑。

[MiYogurt]

去掉这一句话。
