我有这个值,我想覆盖它的一个属性。我尝试了以下方法:fetchOptions: Readonly<HttpFetchOptionsWithPath>
((fetchOptions as Writable<HttpFetchOptionsWithPath>).headers as Writable<any>) = {
'new-value': '123',
...(fetchOptions.headers || {}),
};
但仍然收到错误。TypeError: Cannot assign to read only property 'headers' of object '#<Request>'
执行的 js 代码如下所示:
fetchOptions.headers = __assign({ 'new-value': '123' }, (fetchOptions.headers || {}));
任何想法,我在这里做错了什么?
