登录后，它不会重定向到电池页面，因为路由认为它阻止的标题中没有令牌。我正在尝试两天以上，请好心人。后端的所有逻辑已经完美运行。用户无法替代路径来登录并生成令牌。系统将其重定向到电池路线

上面的代码通过尝试“更改要不受控制的文本类型的受控输入”来触发附加（不相关）警告。要解决此问题，请将FormComponent切换为Controlled strategy，使用组件状态来管理输入值和验证，并按需绑定所需的方法来处理登录请求或一些异步验证。
与认证问题有关，这似乎是因为在应用程序加载时Router模块已经设置了responseIsAuthenticated值，从而提前评估了令牌状态。为了确保始终评估当前状态，您必须在isAuthenticated属性内调用render方法：
const PrivateRoute = ({ component: Component, ...rest }) => (
<Route {...rest} render={props => (
// Call to isAuthenticated here.
isAuthenticated() ? (
<Component {...props} />
) : (
<Redirect to={{ pathname: "/login", state: { from: props.location } }} />
)
)} />
)
此外，为了在成功登录后重定向用户。我建议在“ LoginComponent”中附加一个Redirect组件：
render() {
const { signIn, fieldErrors, email, password, loadedOne } = this.state
if(signIn.success)
return <Redirect to={{ pathname: "/batteries"}} />;
/* <Form /> */
