问题 Given an image url, how can I upload that image to Google Cloud Storage for image processing using Node.js? 回答1: It's a 2 steps process: Download file locally using request or fetch. Upload to GCL with the official library. var fs = require('fs'); var gcloud = require('gcloud'); // Authenticating on a per-API-basis. You don't need to do this if you auth on a // global basis (see Authentication section above). var gcs = gcloud.storage({ projectId: 'my-project', keyFilename: '/path/to/keyfile

问题 Hi I'm building a program in Ruby to generate alt attributes for images on a webpage. I'm scraping the page for the images then sending their src, in other words a URL, to google-cloud-vision for label detection and other Cloud Vision methods. It takes about 2-6 seconds per image. I'm wondering if there's any way to reduce response time. I first used TinyPNG to compress the images. Cloud Vision was a tad faster but the time it took to compress more than outweighed the improvement. How can I
