node.js - cloudinary 多个.jpg上传NODE.JS

Question

你们中有人尝试过将 50 多张图片上传到 cloundinary 吗？我一直在尝试，但问题是 Promise 没有得到解决(即使使用 .reflect() 并且无法上传所有图像。根据上传速度，它会失败 30% ~ 70%。

有什么方法可以完全异步并确保所有图像都正确上传吗？我使用的唯一模块是来自他们文档的 bluebird 和 cloudinary 模块。

Promisebd = require('bluebird');

function uploadimg(img, i, itemId) {
  var pubID = 'a2z/toys/' + itemId + '/' + i;
  // return new cloudImg.v2.uploader.upload(img, {
  return cloudinary.v2.uploader.upload(img, { // works
    public_id: pubID,
    quality: 90
    // use_filename: true,
  } , function(err, res){
    if(err) {
      console.log(err);
    }
    console.log(res);
  });
}


promiseArr.push(uploadimg(fullimg, i, d[0].details.detailsProductId)); // pushing the promises to Arr

  Promisebd.all(promiseArr.map(function(promise) {
            return promise.reflect();
          })).each(function(inspection) {
            if(inspection.isFulfilled()) {
              console.log('The promise is the arr was fulfilled with ', inspection.value());
            }else{
              console.log('The promise is NOT the arr was NOT fulfilled with ', inspection.reason());
            }
          })

promise 你的上传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);   
        }); 
    });   
}
