在些react组件的时候，会有这个警告
Can‘t perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in the componentWillUnmount method”
这是因为在写一个方法完成请求后我们改变state状态，
payload:values, callback:res=>{ if(res.code === 0){ notification.success({ message: ‘密码更新成功‘, description: `新密码为 ${res.data}`, duration: 0, }); successed&& successed(); that.setState({ updatePwdModalVisible:false }) that.getCaptcha();
解决方法：利用生命周期钩子函数：componentWillUnmount，在组件卸载前清除timer
that.pwdErrorTimer = setTimeout(() => {
this.setState({
updatePwdModalVisible:false
})
}, 1000);
componentWillUnmount(){
clearTimeout(this.pwdErrorTimer);
}
