ReactJS路由可選ID的URL參數

Question

所以，我試過所有這些，但都沒有工作。同樣的錯誤的

<Route name="create-course" handler={CreateCourse} path="/course-builder/create-course/{:id}" /> 
<Route name="create-course" handler={CreateCourse} path="/course-builder/create-course/[:id]" /> 
<Route name="create-course" handler={CreateCourse} path="/course-builder/create-course{/id}" /> 

變種：

Error: Invariant Violation: Missing "id" parameter for path "/course-builder/create-course/{:id}" 

/{：？ID}一個不會引發錯誤，但URL成爲

/course-builder/create-course/%7B%7D 

請幫助！

Answer 1

PARAM :id後添加?，像這樣

<Route name="create-course" handler={CreateCourse} path="/course-builder/create-course/:id?" /> 

Answer 2

萬一別人絆倒在這個問題 - 因爲陣營 - 路由器的V1.0.0正確的語法是：

<Route name="create-course" handler={CreateCourse} path="/course-builder/create-course(/:id)" />
