URLSearchParams不接受字符串

Question

const sortString = req.query.sort as string
const params = Object.fromEntries(new URLSearchParams(sortString))

现在，当我开始执行时，我得到：

declare var URLSearchParams: {
    prototype: URLSearchParams;
    new(init?: string[][] | Record<string, string> | string | URLSearchParams): URLSearchParams;
    toString(): string;
};

现在，我很困惑为什么它不能处理类型记录，因为它应该接受一个字符串。

No overload matches this call.
  Overload 1 of 2, '(entries: Iterable<readonly [PropertyKey, any]>): { [k: string]: any; }', gave the following error.
    Argument of type 'URLSearchParams' is not assignable to parameter of type 'Iterable<readonly [PropertyKey, any]>'.
      Property '[Symbol.iterator]' is missing in type 'URLSearchParams' but required in type 'Iterable<readonly [PropertyKey, any]>'.
  Overload 2 of 2, '(entries: Iterable<readonly any[]>): any', gave the following error.
    Argument of type 'URLSearchParams' is not assignable to parameter of type 'Iterable<readonly any[]>'.
      Property '[Symbol.iterator]' is missing in type 'URLSearchParams' but required in type 'Iterable<readonly any[]>'.ts(2769)

错误声明传递给fromEntries的参数必须是可迭代的，而不是。从TS定义来看，URLSearchParams在https://github.com/microsoft/TypeScript/blob/2f13eba42c76d02f2e5c79060d6018ee8c7fecc9/lib/lib.dom.iterable.d.ts#L285中被定义为可迭代的，所以这个定义很可能没有加载到项目的任何TS配置中。
