rails 4 amazon s3 seahorse getaddrinfo错误

Question

我正在尝试使用aws-sdk的第2版完成此tutorial，我已经包含了这些额外的宝石

gem 'aws-sdk-core'

gem 'dotenv-rails', :groups => [:development, :test]

根文件夹中的.env文件是

S3_BUCKET=XXXredactedXXX
AWS_ACCESS_KEY_ID=XXXXXXXXXXXXXXredactedXXXXXX
AWS_SECRET_ACCESS_KEY=XXXXXredactedXXXXXX
AWS_REGION=Oregon

我试图通过在rails控制台中运行这些命令来测试配置。

s3 = Aws::S3::Client.new
resp = s3.list_buckets
resp.buckets.map(&:name)
#=> ["bucket-1", "bucket-2", ...]

我假设.env文件中的配置正在运行，因为没有AWS_REGION条目它会引发此错误

  

Aws :: Errors :: MissingRegionError：缺少区域;使用：区域选项或   将区域名称导出到ENV [＆＃39; AWS_REGION＆＃39;]

这个＆＃39; resp = s3.list_buckets＆＃39;命令触发此错误＆＃39; Seahorse :: Client :: NetworkingError：getaddrinfo：名称或服务未知＆＃39;

**更新，凭据设置和工作

亚马逊有一个红宝石样本here和许多凭据选项here。有一个命令行工具aws命令行实用程序here。此工具使用凭据和配置文件创建目录（.aws）。这取代了我相信的.env宝石，因为它有同样的目的。

凭证

[default]
aws_access_key_id = XXXXXredcatedXXX
aws_secret_access_key = XXXXXredactedXXXX

配置

[default]
#region = us-west-2
#output = json

正如您所看到的那样，区域已被注释掉并且不会影响ruby示例，因为在创建资源实例时会提供区域。

的Gemfile

source 'https://rubygems.org'
gem 'aws-sdk', '~> 2.0.22'
gem 'uuid', '~> 2.3.7'

require 'rubygems'
require 'bundler/setup'
require 'aws-sdk'
require 'uuid'

s3 = Aws::S3::Resource.new(region: 'us-west-2')

uuid = UUID.new
bucket_name = "ruby-sdk-sample-#{uuid.generate}"
bucket = s3.bucket(bucket_name)
bucket.create

object = bucket.object('ruby_sample_key.txt')
object.put(body: "Hello World!")

Answer 1

最后我找到了一个解决方案，这个stackoverflow post添加了AWS

通过在根目录[〜/]中创建文件夹[.aws]，然后创建包含以下内容的凭据和配置文件

，像以前一样设置凭据

凭证

[default]
aws_access_key_id = XXXXXredcatedXXX
aws_secret_access_key = XXXXXredactedXXXX

配置

[default]
#region = us-west-2
#output = json

将这2个宝石添加到生成的Gemfile

中

gem 'carrierwave'
gem 'aws-sdk', '~> 2'

我修改过的PostsController，Carrierwave确实有一种方法可以确定保存后文件的路径，但是我无法让它工作。

class PostsController < ApplicationController

  skip_before_action :verify_authenticity_token

  before_action :set_post, only: [:show, :edit, :update, :destroy]

  # GET /posts
  # GET /posts.json
  def index
    @posts = Post.all
  end

  # GET /posts/1
  # GET /posts/1.json
  def show

    @post_attachments = @post.post_attachments.all

  end

  # GET /posts/new
  def new

    @post = Post.new

    @post_attachment = @post.post_attachments.build

  end

  # GET /posts/1/edit
  def edit
  end

  # POST /posts
  # POST /posts.json
  def create

    s3 = Aws::S3::Resource.new(region: 'us-west-2')

    bucket = s3.bucket('my-first-bucket-tutorial1985')

    @post = Post.new(post_params)

    respond_to do |format|
      if @post.save
        params[:post_attachments]['avatar'].each do |a|

          @post_attachment = @post.post_attachments.create!(:avatar => a, :post_id => @post.id)

          File.open('public/uploads/post_attachment/avatar/' + "#{@post_attachment[:post_id]}" + '/'+ "#{@post_attachment[:avatar]}", 'rb') do |file|
            s3.bucket('my-first-bucket-tutorial985').object("#{@post_attachment[:avatar]}").put(body:file)
          end



        end

          format.html { redirect_to @post, notice: 'Post was successfully created.' }
       # format.json { render :show, status: :created, location: @post }
      else
        format.html { render :new }
       # format.json { render json: @post.errors, status: :unprocessable_entity }
      end
    end
  end

  # PATCH/PUT /posts/1
  # PATCH/PUT /posts/1.json
  def update
    respond_to do |format|
      if @post.update(post_params)
        format.html { redirect_to @post, notice: 'Post was successfully updated.' }
        format.json { render :show, status: :ok, location: @post }
      else
        format.html { render :edit }
        format.json { render json: @post.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /posts/1
  # DELETE /posts/1.json
  def destroy
    @post.destroy
    respond_to do |format|
      format.html { redirect_to posts_url, notice: 'Post was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_post
      @post = Post.find(params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def post_params
      params.require(:post).permit(:title, post_attachments_attributes: [:id, :post_id, :avatar])
    end
end

它起作用的证据
