this.props 使用 ApolloClient 时无法访问
this.props not accessible when using ApolloClient
我正在使用 apollo-boost,我已经创建了一个 ApolloClient,我想在突变 运行 之后做一些重定向,但我无法访问道具
index.js
import React from "react";
import ReactDOM from "react-dom";
import { BrowserRouter } from "react-router-dom";
import { ApolloProvider } from "react-apollo";
import ApolloClient from "apollo-boost";
import "./bootstrap";
import Routes from "./RoutesComponent";
const client = new ApolloClient({
uri: "http://localhost:4000/graphql"
});
const Root = () => {
return (
<ApolloProvider client={client}>
<BrowserRouter>
<Routes />
</BrowserRouter>
</ApolloProvider>
);
};
ReactDOM.render(<Root />, document.querySelector("#root"));
路由组件
import React, { Component } from "react";
import { Route, Switch } from "react-router-dom";
import Register from "./authenticate/register/RegisterComponent";
import Login from "./authenticate/login/LoginComponent";
import Product from "./customers/product/ProductComponent";
import AddProduct from "./customers/add-product/AddProductComponent";
import Products from "./customers/products/ProductsComponent";
import AdminProduct from "./admin/product/ProductComponent";
import AdminProducts from "./admin/products/ProductsComponent";
class RoutesComponent extends Component {
render() {
return (
<Switch>
<Route path="/products/new" render={() => <AddProduct />} />
</Switch>
);
}
}
export default RoutesComponent;
添加产品组件
import React, { Component } from "react";
class AddProductComponent extends Component {
render() {
console.log(this.props);
return (
<div>
<h1>AddProductComponent</h1>
</div>
);
}
}
export default AddProductComponent;
this.props 在控制台中显示 {}
为了缓解这种情况,我还尝试使用 history 包,它更改了 url 但重定向不起作用
我可以使用 state 进行重定向,但我宁愿使用 history prop 而不是 state。
如有任何建议,我们将不胜感激。
Route
的渲染函数将 props
作为参数,由于您没有传递它,它在组件中将不可用
<Route path="/products/new" render={() => <AddProduct />} />
固定:
<Route path="/products/new" component={AddProduct} />
