我一直试图通过omniauth-twitter gem和twitter-gem以及下面的代码让我的rails应用程序的用户发推文，但每次我发送推文时，我都会收到以下错误
“Twitter::Error::Forbidden - Your credentials do not allow access to this resource:”
我为Twitter设置了以下代码。
def tweet(tweet)
client = Twitter::REST::Client.new do |config|
config.consumer_key = ENV["TWITTER_CONSUMER_KEY"]
config.consumer_secret = ENV["TWITTER_CONSUMER_SECRET"]
config.access_token = ENV["TWITTER_ACCESS_TOKEN"]
config.access_token_secret = ENV["TWITTER_ACCESS_SECRET"]
end
client.update(tweet)
end
resources :tweets, only: [:new, :create]
class Devise::SessionsController < DeviseController
prepend_before_filter :require_no_authentication, :only => [ :new, :create ]
prepend_before_filter :allow_params_authentication!, :only => :create
prepend_before_filter { request.env["devise.skip_timeout"] = true }
# GET /resource/sign_in
def new
self.resource = resource_class.new(sign_in_params)
clean_up_passwords(resource)
respond_with(resource, serialize_options(resource))
respond_to do |format|
format.js
end
end
# POST /resource/sign_in
def create
self.resource = warden.authenticate!(auth_options)
set_flash_message(:notice, :signed_in) if is_navigational_format?
sign_in(resource_name, resource)
respond_with resource, :location => after_sign_in_path_for(resource)
end
# DELETE /resource/sign_out
def destroy
redirect_path = after_sign_out_path_for(resource_name)
signed_out = (Devise.sign_out_all_scopes ? sign_out : sign_out(resource_name))
set_flash_message :notice, :signed_out if signed_out && is_navigational_format?
# We actually need to hardcode this as Rails default responder doesn't
# support returning empty response on GET request
respond_to do |format|
format.all { head :no_content }
format.any(*navigational_formats) { redirect_to redirect_path }
end
end
protected
def sign_in_params
devise_parameter_sanitizer.sanitize(:sign_in)
end
def serialize_options(resource)
methods = resource_class.authentication_keys.dup
methods = methods.keys if methods.is_a?(Hash)
methods << :password if resource.respond_to?(:password)
{ :methods => methods, :only => [:password] }
end
def auth_options
{ :scope => resource_name, :recall => "#{controller_path}#new" }
end
end
class TweetsController < ApplicationController
def new
end
def create
current_user.tweet(twitter_params[:message])
redirect_to root_path
end
def twitter_params
params.require(:tweet).permit(:message)
end
end
在我看来，我已经为用户设置了一个表单以及一个发送推文的按钮。
<p>
<%= form_for :tweet, url: tweets_path, method: :post do |f| %>
<%= f.text_field :message %>
<%= f.submit "Send Tweet" %>
<% end %>
</p>

答案 0 :(得分：1)
我想你错过了配置：
config.consumer_key = ENV["TWITTER_CONSUMER_KEY"]
config.consumer_secret = ENV["TWITTER_CONSUMER_SECRET"]
config.access_token = ENV["TWITTER_ACCESS_TOKEN"]
config.access_token_secret = ENV["TWITTER_ACCESS_SECRET"]
如果未设置环境变量，您将收到“未经授权”的错误。
仅用于测试目的，尝试实际输入您的数据而不是ENV变量...它可以工作，这意味着您错误地传递了yml文件。
