本文介绍了carrierwave Excon :: Errors :: SocketError的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我已经阅读了与此相关的几篇文章和解决方案，但我仍然无法弄清楚，仍然在/ posts
处返回
Excon :: Errors :: SocketError getaddrinfo：nodename （SocketError）
这是config / carrierwave.rb
CarrierWave.configure do | config |
config.fog_credentials = {
：provider => 'AWS'，＃需要
：aws_access_key_id => '----'，＃required
：aws_secret_access_key => '----'，＃需要
：region => 'eu-west-1'，＃可选，默认为'us-east-1'
：host => 's3.example.com'，＃可选，默认为零
：endpoint => 'https://s3.example.com:8080'＃可选，默认为零
}
config.fog_directory ='name_of_directory'＃必填
config.fog_public = false＃可选，默认值to true
config.fog_attributes = {'Cache-Control'=>'max-age = 315576000'}＃可选，默认为{}
config.asset_host ='https：//assets.example .com'
end
avatar_upload.rb
＃encoding：utf-8
class AvatarUploader< CarrierWave :: Uploader :: Base
包括CarrierWave :: MiniMagick
storage：fog
process：resize_to_fit => [900,500]
版本：thumb do
过程：resize_to_fill => [200,200]
end
def cache_dir
＃{Rails.root} / tmp / uploads

$ b $ def store_dir

结束

来自后控制器
def创建
@post = Post.new（post_params）
@ post.user = current_user
除非current_user.admin？
除非current_user.manager？
redirect_to：back，：alert => acces denied
end
end
respond_to do | format |
if @ post.save
params [：photo_attachments] ['avatar']。each do | a |
@photo_attachment = @ post.photo_attachments.create！（：avatar => a，：post_id => @ post.id）
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
在安装carrierwave-aws后更新config / carrierwave.rb
CarrierWave。配置do | config |
config.storage =：aws
config.aws_bucket = ENV ['S3_BUCKET_NAME']
config.aws_acl =：public_read
config.asset_host ='http://example.com '
config.aws_authenticated_url_expiration = 60 * 60 * 24 * 365
config.aws_credentials = {
access_key_id：ENV ['---']，
secret_access_key： ENV ['---']
}
结束
存储：aws
AWS ::错误:: MissingCredentialsError
缺少凭证。
无法找到AWS凭证。您可以通过几种不同的方式配置您的AWS凭证
a：
*使用access_key_id和：secret_access_key调用AWS.config
*将AWS_ACCESS_KEY_ID和AWS_SECRET_ACCESS_KEY导出到ENV
*在EC2上，您可以使用IAM实例配置文件运行实例，凭证
将从这些
实例上的实例元数据服务自动加载。
*使用：credential_provider调用AWS.config。证书提供者应该
包含AWS :: Core :: CredentialProviders :: Provider或者对
使用相同的公共方法。
= Ruby on Rails
在Ruby on Rails应用程序中，您还可以通过以下方式在
中指定凭证：
*通过配置初始化脚本使用上面提到的任何方法
（例如RAILS_ROOT / config / initializers / aws-sdk.rb）。
*通过位于RAILS_ROOT / config / aws.yml的yaml配置文件。
这个文件应该像默认的RAILS_ROOT / config / database.yml
文件一样被格式化。
解决方案
这可能是因为使用 fog ，可能试着将你的gem切换到 carrierwave-aws ，看看它是否解决了你的问题：）
我记得有类似的错误，并且在更改后，工作正常！
I have read several posts and solutions related to this, but I still cannot figure it out and still returns "Excon::Errors::SocketError at /postsgetaddrinfo: nodename nor servname provided, or not known (SocketError)"
this is config/carrierwave.rb
CarrierWave.configure do |config|
config.fog_credentials = {
:provider => 'AWS', # required
:aws_access_key_id => '----', # required
:aws_secret_access_key => '----', # required
:region => 'eu-west-1', # optional, defaults to 'us-east-1'
:host => 's3.example.com', # optional, defaults to nil
:endpoint => 'https://s3.example.com:8080' # optional, defaults to nil
}
config.fog_directory = 'name_of_directory' # required
config.fog_public = false # optional, defaults to true
config.fog_attributes = {'Cache-Control'=>'max-age=315576000'} # optional, defaults to {}
config.asset_host = 'https://assets.example.com'
end
avatar_upload.rb
# encoding: utf-8
class AvatarUploader < CarrierWave::Uploader::Base
include CarrierWave::MiniMagick
storage :fog
process :resize_to_fit => [900,500]
version :thumb do
process :resize_to_fill => [200,200]
end
def cache_dir
"#{Rails.root}/tmp/uploads"
end
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
def default_url
# # For Rails 3.1+ asset pipeline compatibility:
# # ActionController::Base.helpers.asset_path("fallback/" + [version_name, "default.png"].compact.join('_'))
#
"/images/fallback/" + [version_name, "default.png"].compact.join('_')
end
def extension_white_list
%w(jpg jpeg gif png)
end
end
from post controller
def create
@post = Post.new(post_params)
@post.user = current_user
unless current_user.admin?
unless current_user.manager?
redirect_to :back, :alert => "acces denied"
end
end
respond_to do |format|
if @post.save
params[:photo_attachments]['avatar'].each do |a|
@photo_attachment = @post.photo_attachments.create!(:avatar => a, :post_id =>@post.id)
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
updated config/carrierwave.rb after installing carrierwave-aws
CarrierWave.configure do |config|
config.storage = :aws
config.aws_bucket = ENV['S3_BUCKET_NAME']
config.aws_acl = :public_read
config.asset_host = 'http://example.com'
config.aws_authenticated_url_expiration = 60 * 60 * 24 * 365
config.aws_credentials = {
access_key_id: ENV['---'],
secret_access_key: ENV['---']
}
end
after changing to storage :aws
AWS::Errors::MissingCredentialsError
Missing Credentials.
Unable to find AWS credentials. You can configure your AWS credentials
a few different ways:
* Call AWS.config with :access_key_id and :secret_access_key
* Export AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY to ENV
* On EC2 you can run instances with an IAM instance profile and credentials
will be auto loaded from the instance metadata service on those
instances.
* Call AWS.config with :credential_provider. A credential provider should
either include AWS::Core::CredentialProviders::Provider or respond to
the same public methods.
= Ruby on Rails
In a Ruby on Rails application you may also specify your credentials in
the following ways:
* Via a config initializer script using any of the methods mentioned above
(e.g. RAILS_ROOT/config/initializers/aws-sdk.rb).
* Via a yaml configuration file located at RAILS_ROOT/config/aws.yml.
This file should be formated like the default RAILS_ROOT/config/database.yml
file.
解决方案
This is possibly because of an implementation with fog, perhaps try switching your gem to carrierwave-aws and see if it fixes your problems :)

I remember having a similar error and after changing, works fine!
