如何在ts中将字符串url设置为对象类型？
样本代码：

type KeyUrl<T> = T extends `/${infer U}` ? U : never;
type TUrl<T> = { [k in KeyUrl<T>]: string };

// --------------------------------------------- this line work
const url = "/path";
const obj = {} as TUrl<typeof url>;
obj.path // work;

// --------------------------------------------- this line error
const url = "/path/path2";
const obj = {} as TUrl<typeof url>;
obj.path // Property 'path' does not exist;
obj.path2 // Property 'path2' does not exist;

谢谢。
