reactjs - "stateless"组件中的上下文？

Question

我的组件中有以下代码，我希望无状态组件能够访问这部分代码:

主要成分:

function createApp(store, communityIds) {
const App = React.createClass({

    childContextTypes: {
        localizedString: React.PropTypes.func,
    },

    getChildContext: function() {
        return {
            localizedString: function(key, fallback) {
                return getKey(key, fallback);
            },
        };
    },

    render: function() {
        return (
            <Provider store={store}>
                <Client communityIds={communityIds}/>
            </Provider>
        );
    },
});

return <App/>;
}

无状态:

export default () => (dispatch, getState) => {
    const state = getState();

    const token = state.user.get('token');

    if (!token) {
        throw new Error('test'); // this.context.localizedString does not work
    }
}

您在“无状态:”函数的定义下提供的内容并不是无状态函数。您已将 Action 创建者作为 thunk 提供。我假设您想插入客户端组件的代码。要访问无状态组件中的上下文，您的客户端组件将执行类似的操作(记录在 here 中)

const Client = (props, context) => {   
    return  <div >{context.localizedString("someKey", "someFallback")} </div>
}

Client.contextTypes = {
    localizedString: React.PropTypes.func
}

export default Client
