出现这个错误是因为在前端获取后端数据后,尝试使用了undefined的push方法。这可能是由于在使用vue-router@4的时候,将解构router方法放在了函数中,导致函数作用域的问题。在这种情况下,当尝试调用router.push方法时,router为undefined,从而导致了这个错误。为了解决这个问题,你可以将解构router方法放在函数外部,以确保在函数内部能够正确访问到router对象。或者,你可以在函数内部使用this.$router.push方法来替代router.push方法。这样可以确保在函数内部能够正确调用路由跳转的功能。请注意,这需要确保你的路由实例正确地引入和配置。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
