node.js - 严重错误 : [Error: Input file is missing]

Question

我通过request下载图片，然后通过sharp处理图片.
但是出现输入文件丢失的错误，实际上是变量body有一个值(value)。

import { IADLandingPageABTest } from '@byted/ec-types';
import request from 'request';
import sharp from 'sharp';

const images: Array<keyof IADLandingPageABTest> = ['topPosterUrl', 'bottomPosterUrl'];

export default function handleImage (config: IADLandingPageABTest) {
    images.forEach(key => {
        const url = config[key];
        if (url && typeof url === 'string' ) {
           request(url, (err, response, body) => {
               //console.log('body', body);
               //body has a value
               if (!err && response.statusCode === 200) {
                sharp(body)
                .resize(100)
                .toBuffer()
                .then((data) => {
                    console.log(data.toString('base64'));
                })
                .catch( err => { console.log('error', err) });
               }
           })
        }
    });
}

我在 sharp 上发现了一个问题概述解决方案的 repo :

the request module expects encoding to be set to receive body as a Buffer.

- request(url, function(error, response, body) {
+ request({ url, encoding: null }, function(error, response, body) {
