使用ruby将文件http放置到S3预签名URL

2023-04-17 00:07:00

http PUT a file to S3 presigned URLs using ruby

任何人都有一个使用ruby在s3上发布到预签名URL的有效示例

我同时使用了aws-sdk和right_aws。

这是执行此操作的代码。

require 'rubygems'
require 'aws-sdk'
require 'right_aws'
require 'net/http'
require 'uri'
require 'rack'

access_key_id = 'AAAAAAAAAAAAAAAAA'
secret_access_key = 'ASDFASDFAS4646ASDFSAFASDFASDFSADF'

s3 = AWS::S3.new( :access_key_id => access_key_id, :secret_access_key => secret_access_key)

right_s3 = RightAws::S3Interface.new(access_key_id, secret_access_key, {:multi_thread => true, :logger => nil} )

bucket_name = 'your-bucket-name'
key ="your-file-name.ext"

right_url = right_s3.put_link(bucket_name, key)
right_scan_command ="curl -I --upload-file #{key} '#{right_url.to_s}'"
system(right_scan_command)

bucket = s3.buckets[bucket_name]
form = bucket.presigned_post(:key => key)
uri = URI(form.url.to_s + '/' + key)
uri.query = Rack::Utils.build_query(form.fields)
scan_command ="curl -I --upload-file #{key} '#{uri.to_s}'"
system(scan_command)

我知道这是一个较旧的问题，但是我想知道同一件事，并在AWS S3文档中找到了一个优雅的解决方案。

require 'net/http'

file ="somefile.ext"
url = URI.parse(presigned_url)
Net::HTTP.start(url.host) do |http|
http.send_request("PUT", url.request_uri, File.read(file), {"content-type" =>"",})
end

这对于我的Device Farm上传非常有效。

能否提供有关"预签名URL"如何工作的更多信息？是这样的：
