如何在深度对象路径的Typescript泛型约束中使用文字字符串参数？

function getValue<T, K extends keyof T>(obj: T, path: K): T[K] {
  // 实现逻辑
}

const pathArray = path.split('.');

const value = pathArray.reduce((acc, key) => acc[key], obj);

return value;

function getValue<T, K extends keyof T>(obj: T, path: K): T[K] {
  const pathArray = path.split('.');
  const value = pathArray.reduce((acc, key) => acc[key], obj);
  return value;
}

interface Person {
  name: string;
  age: number;
  address: {
    city: string;
    street: string;
  };
}

const person: Person = {
  name: 'John',
  age: 30,
  address: {
    city: 'New York',
    street: '123 ABC Street',
  },
};

const name = getValue(person, 'name'); // 返回 'John'
const city = getValue(person, 'address.city'); // 返回 'New York'
