轨道3，Heroku的，AWS-S3，无非是想将文件上载到张贴（HTTP /多部分），以我们的应用程序S3 [英] rails 3, heroku, aws-s3, simply trying to upload a file to S3 that is POSTed (http/multipart) to our app

问题描述

我们的应用程序托管在Heroku的，所以没有本地文件存储。

Our app is hosted at Heroku, so no local file storage.

我们正在使用不保存它创建了一个WAV第三方API，它帖子的文件（HTTP /多部分）回到我们的应用程序。它们提供样品code为简单的发送文件到S3。在code，他们提供（下同）不on Rails的3 + Heroku上运行。我怀疑有一些不同的语法来指定输入文件和临时文件从中读出。 （在code最初是为西纳特拉我不知道老 [：文件名] 和 [：临时文件] 是对，所以我把他们赶走，并采取了猜测的语法是这个东西用它视为是怎样的？）

A third party api we're using doesn't store a WAV it creates, it POSTs the file (http/multi-part) back to our app. They provide sample code to 'simply' send that file on to S3. The code they supply (below) doesn't run on Rails 3 + Heroku. I suspect there's some different syntax for specifying the input file and temp file from which we read. (The code was originally for Sinatra. I have NO idea what the old [:filename] and [:tempfile] were for so I removed them and took a guess the syntax was something like this using Tempfile?)

  def post_audio_to_s3
    puts "*** POST_AUDIO_TO_S3 PARAMS:" + params.inspect

    con = AWS::S3::Base.establish_connection!(
      :access_key_id     => 'MYKEY',
      :secret_access_key => 'MYSECRET')

    puts "** CON='#{con.inspect}'"

    snd = AWS::S3::S3Object.store(params[:filename], 
                        Tempfile.open(params[:filename]).path, 
                        'bb_audios')
    puts "** SND='#{snd.inspect}'"

更新：几乎工作，但零长度的文件创建。排序我挥舞着周围不知道如何使用它视为档案，但我加了要求临时文件到控制器类和修改的S3存储产品线以上。

UPDATE: Almost works ,but zero length file created. I'm sort of flailing around with no idea how to use the Tempfile, but I added require 'tempfile' to the controller class and modified the S3 storage line to the above.

这整个后一个文件到Heroku的/它视为事已了我的大脑冰镇...任何想法将AP preciated。对于一件事......我不知道那里的数据来自......我不应该看到的东西，除了文件名，当我检查PARAMS如果它被发布到应用程序？

This whole POST-a-file to Heroku/Tempfile thing has my brain iced... any ideas would be appreciated. For one thing... I have no idea where the DATA comes from... shouldnt I see something besides the filename when I inspect the params if it's being POSTED to the app?

推荐答案

答案是如下。我们必须从文件名更改URL参数=来= MyFileName的，因为魔术导轨自动使用文件名为发布的数据，以便他们在PARAMS重踏在彼此[]。

The answer was as follows. We had to change the url parameter from filename= to myfilename= because the rails magic automatically uses 'filename' for the POSTed data so they were stomping over each other in the params[].

openme = params['filename'].tempfile.path

snd = AWS::S3::S3Object.store(params[:myfilename], 
                        File.open(openme), 
                        'MYBUCKET')
