從Ruby中的圖像url將圖像上傳到AWS？

Question

我有一個來自圖像標記的源網址，我想將該圖像上傳到我的S3存儲桶。我將如何做到這一點？ A-Ha！

Answer 1

A-Ha！我已經有了答案，但發現這很難找出...

不幸的是，我沒有先從源URL下載有問題的文件，我無法完成此任務。

因此，這裏是我如何上傳產品圖片：

首先設置你的S3存儲在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']) 

然後我創建的應用程序/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 

然後，所有你需要做的就是調用：

AwsImporter.new.upload_from_url(img_url, product_name) 

這正是我如何通過我們可以控制的產品和image_urls來挖掘整個網站的種子。
