Question

你们中的任何一个试图将50多张图片上传到cloundinary吗？我一直在尝试，但问题是承诺没有得到解决（即使使用.reflect（）并且无法上传所有图像。根据上传的速度，它将失败30％~70％。

有没有办法让它完全异步并确保所有图片都正确上传？我正在使用的模块只是来自doc的bluebird和cloudinary模块。

宣传您的上传img功能并尝试使用它

function uploadimgAsync(img, i, itemId) {
    return new Promise(function (resolve, reject) {
        var pubID = 'az/toys/' + itemId + '/' + i;   
        cloudinary.v2.uploader.upload(img, { // works
            public_id: pubID,
            quality: 90  
        }, 
        function(err, res){
             if(err) {
                 reject(err);
             }
             resolve(res);   
        }); 
    });   
}
