withRouter、connect() 和 react-compose [英] withRouter, connect() and react-compose
本文介绍了withRouter、connect() 和 react-compose的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在使用 react-redux 连接函数和 withRouter 函数，并且我也尝试在这里使用 compose() .这是代码:
I am using react-redux connect function with withRouter function, and also I am trying to use compose() here. This is the code:
export default compose (
withRouter,
connect(mapStateToProps)
)(Dashboard);
但我收到下一个错误:

这里有什么问题?
推荐答案
connect 返回一个接受组件的函数.所以，我认为如果你稍微改变你的括号会奏效:
connect returns a function that takes the component. So, I think it would work if you slightly change your parens:
export default compose(
withRouter,
connect(mapStateToProps)(Dashboard)
);
或者:
export default connect(mapStateToProps)(compose(
withRouter,
Dashboard
));
