我有一个React组件,它接受用户名和密码并将其发送以进行身份​​验证.如果身份验证成功,则页面应移至呈现其他组件的其他路由.

现在的问题是,我不确定如何更改商店的路线？即不使用< Link> React Router的组件？我知道我们可以使用this.props.history.push(/ url)以编程方式更改路线,但只能在使用< Route>的React Component内部使用它,而不能在商店中使用.

我正在将React16和MobX一起用于状态管理,并使用ReactRouter V4进行路由.

商店：

class Store {
    handleSubmit = (username, password) => {
        const result = validateUser(username, password);
        // if result === true, change route to '/search' to render Search component
    }
}

登录组件：

const Login = observer(({ store }) => {
    return (
        <div>
           <form onSubmit={store.handleSubmit}>
                <label htmlFor="username">User Name</label>
                <input type="text" id="username" onChange={e => store.updateUsername(e)} value={store.username} />
                <label htmlFor="password">Password</label>
                <input type="password" id="password" onChange={e => store.updatePassword(e)} value={store.password} />
                <input type="submit" value="Submit" disabled={store.disableSearch} />
            </form>}
        </div>
    )
})

主要应用组件：

import { Router, Route, Link } from "react-router-dom";
@observer
class App extends React.Component {
    render() {
        return (
            <Router history={history}>
                <div>
                    <Route exact path="/"
                        component={() => <Login store={store} />}
                    />

                    <Route path="/search"
                        component={() => <Search store={store} />}
                    />
                </div>
            </Router>
        )
    }
}

解决方法:

您可以在单独的模块中创建历史记录,然后将其导入到主应用程序的Component和Store中：

// history.js
import createHistory from 'history/createBrowserHistory';

const history = createHistory();

export default history;

// Store.js
import history from './history';

class Store {
    handleSubmit = (username, password) => {
        const result = validateUser(username, password);

        if (result) {
            history.push('/search');
        }
    }
}

// App.js
import { Router, Route, Link } from "react-router-dom";
import history from './history';

@observer
class App extends React.Component {
    render() {
        return (
            <Router history={history}>
                <div>
                    <Route exact path="/"
                        component={() => <Login store={store} />}
                    />

                    <Route path="/search"
                        component={() => <Search store={store} />}
                    />
                </div>
            </Router>
        )
    }
}
