我正在使用使用React Router 4的React应用程序工作。但是,如果我走到不在列表中的路由,那么我的所有路由都工作正常,但我的404页面却收不到。知道我缺少什么吗?
我正在使用React 16和React Router4。这是针对的示例应用程序,例如的确。
export default function App() {
const companyRoutes = () => (
<Main>
<Route exact path="/companies/new" component={NewCompanyPage} />
<SubNav>
<PageBody companyPages>
<Switch>
<Route exact path="/companies" component={CompanyPage} />
<Route path="/companies/:companyId/edit" component={EditCompanyPage} />
<Route path="/companies/:companyId/jobs/:jobId/edit" component={EditJobPage} />
<Route path="/companies/:companyId/jobs/new" component={NewJobPage} />
<Route path="/companies/:companyId/jobs" component={CompanyJobsPage} />
<Route path="/companies/:companyId/locations" component={CompanyLocationsPage} />
<Route path="/companies/:companyId/recruiters" component={CompanyRecruitersPage} />
<Route path="/companies/:companyId/settings" component={CompanySettingsPage} />
<Route path="/companies/:companyId/applicants" component={CompanyApplicantsPage} />
</Switch>
</PageBody>
</SubNav>
</Main>
)
const jobRoutes = () => (
<Main>
<PageBody>
<Switch>
<Route exact path="/jobs" component={JobsPage} />
<Route path="/jobs/:jobId" component={JobPage} />
<Route path="/jobs/:jobId/apply" component={NewApplicationPage} />
</Switch>
</PageBody>
</Main>
)
const profileRoutes = () => (
<Main>
<SubNav>
<PageBody>
<Switch>
<Route exact path="/profiles" component={ProfilePage} />
<Route path="/profiles/:profileId/resume" component={ResumePage} />
<Route path="/profiles/:profileId/edit" component={EditProfilePage} />
<Route path="/profiles/:profileId/applications" component={ApplicationsPage} />
<Route path="/profiles/:profileId/settings" component={ProfileSettingsPage} />
</Switch>
</PageBody>
</SubNav>
</Main>
)
const loginRoutes = () => (
<LoginMain>
<Switch>
<Route exact path="/login" component={LoginPage} />
<Route exact path="/sign_up" component={LoginPage} />
</Switch>
</LoginMain>
)
const MainRoutes = () => (
<div>
<Route path="/companies" component={companyRoutes} />
<Route path="/jobs" component={jobRoutes} />
<Route path="/login" component={loginRoutes} />
<Route path="/profiles" component={profileRoutes} />
</div>
)
return (
<BrowserRouter>
<div>
<Route path="/" component={MainRoutes} />
<Route path="/404" component={NotFoundPage} />
</div>
</BrowserRouter>
)
}

[UPDATE]:Here,您会找到一个正确的,经过更好测试的示例。
未经测试,但尝试:
return (
<BrowserRouter>
<Switch>
<Route path="/" component={MainRoutes} />
<Route component={NotFoundPage} />
</Switch>
</BrowserRouter>
)
想法是在Switch
内,路由器将尝试从第一个到最后一个的每条路由,直到找到相应的路径。
通过在路由的非常底部中设置<Route component={NotFoundPage} />
,并未指定path
,它将用作通配符,捕获所有不匹配的URL。
