从Ruby中的图像url将图像上传到AWS？

Question

我有一个来自图像标记的源网址，我想将该图像上传到我的S3存储桶。我将如何做到这一点？ A-Ha！

Answer 1

A-Ha！我已经有了答案，但发现这很难找出...

不幸的是，我没有先从源URL下载有问题的文件，我无法完成此任务。

因此，这里是我如何上传产品图片：

首先设置你的S3存储在app /配置/初始化/ aws.rb

Aws.config.update({ 
    region: ENV['AWS_REGION'], 
    credentials: Aws::Credentials.new(ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']), 
}) 

S3_BUCKET = Aws::S3::Resource.new.bucket(ENV['S3_BUCKET_NAME']) 

然后我创建的应用程序/工人/ aws_importer.rb

require 'aws-sdk' 

class AwsImporter 
    def upload_from_url (img_url, product_name) 
    image_file = open(img_url) // stage file for saving locally 
    local_image_path = product_name + ".jpg" // define filename and designate to root directory 
    IO.copy_stream(image_file, local_image_path) // download file to root directory 
    remote_image_path = "/products/#{product_name}/primary_image/#{local_image_path}" // set the desired url path in AWS 
    S3_BUCKET.object(remote_image_path).upload_file(local_image_path) // upload file to S3 
    File.delete(local_image_path) // then delete the local file copy 
    "https://s3.amazonaws.com/#{S3_BUCKET.name}/" + remote_image_path // return the new url path of the uploaded object. 
    end 
end 

然后，所有你需要做的就是调用：

AwsImporter.new.upload_from_url(img_url, product_name) 

这正是我如何通过我们可以控制的产品和image_urls来挖掘整个网站的种子。
