问题描述
页面A跳转到页面B,并传入参数。当离开页面B时,componentWillUnmount()中无法获取this.$router.params中的参数,而页面B的其它地方都能获取该参数。

复现步骤

// Page A
Taro.navigateTo({url: `/pages/b/index?foo=foo`})

// Page B
componentDidMount() {
  const { foo } = this.$router.params
  console.log(foo) // foo
}

componentWillUnmount() {
  const { foo } = this.$router.params
  console.log(foo) // undefined
}
