ReactJS路由可选ID的URL参数

Question

所以，我试过所有这些，但都没有工作。同样的错误的

<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}" /> 

变种：

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

/{：？ID}一个不会引发错误，但URL成为

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

请帮助！

Answer 1

PARAM :id后添加?，像这样

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

Answer 2

万一别人绊倒在这个问题 - 因为阵营 - 路由器的V1.0.0正确的语法是：

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