如何通过ajax发送数据并且url在链接中间有一个变量值

Question

I am using this API:'/api/categories/${catID}/items/addItem/'

from my spring boot java to enter some data to item table which has relation with category table.

Now in javascript, I used ajax: $.ajax({ url: '/api/categories/${catID}/items/addItem/', type: "POST", contentType: "application/json", etc

Now I get a problem from the url and cannot read the value of ${catID}

This is the real API: "/api/categories/{categoryId}/items/addItem" I have looked inside the site but the solution does not work with me. Now how can I pass a value of a variable if the variable are in the middle.

Thanks in advance.

您正在尝试使用需要反引号 (`) 而不是单引号 (') 的模板文字。

url: `/api/categories/${catID}/items/addItem/`
