我对异步请求有疑问。最后的承诺没有解决。 因此，我认为问题可能出在“探针”内部情况上。 我做了一个异步/等待，我的代码的所有部分开始同步，但是最后一个Promise不能在这里解决-（packer.toBuffer（doc））; 我也试图重写Promise []这部分-
await probe(urlObj.url).then(async result => {
const scale = result.width / DEFAULT_WIDTH_DOCUMENT;
await doc.createImage(
await requestPromise(urlObj.url),
result.width,
result.height
);
// image.scale(scale);
});

const contentAddress = (company.street || '') + ' ' + (company.zipcode || '') + ' ' + (company.city || '');
