React路由报错 `Cannot read property 'push' of undefined`，解决方法是加上`withRouter`，代码示例如下
```
import React from 'react'
import {withRouter} from 'react-router-dom'
class Demo extends React.Component {
handleClick(){
this.props.history.push("/login")
}
render() {
return (
<button onClick={this.handleClick}>去登录</button>
)
}
}
export default withRouter(Demo)
```
