如何在Typescript中键入用于重命名对象键的函数

type RenameMap<T> = {
  [K in keyof T]: string;
};

function renameKeys<T>(obj: T, renameMap: RenameMap<T>): T {
  const renamedObj = {} as T;
  for (const key in obj) {
    if (renameMap.hasOwnProperty(key)) {
      const renamedKey = renameMap[key];
      renamedObj[renamedKey] = obj[key];
    } else {
      renamedObj[key] = obj[key];
    }
  }
  return renamedObj;
}

interface Person {
  name: string;
  age: number;
}

const person: Person = {
  name: "John",
  age: 30,
};

const renameMap: RenameMap<Person> = {
  name: "fullName",
};

const renamedPerson = renameKeys(person, renameMap);
console.log(renamedPerson);

{
  fullName: "John",
  age: 30,
}
