使用request模块上传文件

const Promise = require('bluebird');
const request = Promise.promisify(require('request'));
const fs = require('fs');

const getFileHash = function (filepath, type, start, end) {
    return new Promise((resolve, reject) => {
        const shasum = crypto.createHash(type);
        const s = fs.createReadStream(filepath, { start, end });
        s.on('data', (d) => {
            shasum.update(d);
        });

        s.on('end', () => {
            const d = shasum.digest('hex');
            resolve(d);
        });

        s.on('error', (err) => {
            reject(err);
        });
    });
}
async function  upload() {
    const md5 = await getFileHash('./thumb.jpg', 'md5')
    request({
        method: 'POST',
        headers: { 'content-type': 'multipart/form-data' },
        uri: 'https://api.om.qq.com/video/authvideopic',
        formData: {
            access_token:"******",
            openid:"*****",
            md5:,
            media: fs.createReadStream('./thumb.jpg'),
            vid: '*****',
        }
    }).then(res => {
        console.log(res.body)
    })
}
