我正在使用 react-redux-firebase 进行身份验证和用户管理。一旦用户登录,我想使用 'dahboard/userId' 的 url 将用户导航到他们的仪表板。当用户进行身份验证时,firebase 会给我们一个包含用户 ID 的响应。问题是当我尝试通过 'this.history.push('dahsboard/uid') 完成导航请求时,我不断收到一条错误消息,提示“this”未定义。我很确定这是一个范围界定问题,但我无法确切弄清楚我需要如何构建代码来解决问题。
我已经尝试将 uid 存储为 const。我还尝试将另一个异步功能链接到请求。this.props 未定义或 uid 未定义。
onSubmit = (e) => {
e.preventDefault();
// this.props.signIn(this.state);
this.props.firebase.login(this.state)
.then(function(res){
const userId = res.user.user.uid;
console.log(userId);
this.props.push('/dashboard/userId');
// ! Scoping issue - How to get 'props' in or userId out of this scope
})
.catch(
err => console.log(err.message),
)
}
render() {
const authError = this.props.authError;
return(
