Question

我有这样的事情：

d1 = RequestService.new('env', 'user', 'password')
req_obj = d1.getRequest('0000-0000')
d1.addAttachment(req_obj, 'file_location')

好像它不起作用。 d1.addAttachment没有req_obj。如果我执行d1.addAttachment（＆＃39; 000-000＆＃39;，＆＃39; file_location＆＃39;），那么它可以完美地运行。如果我使用req_obj作为addAttachment中的属性，则会失败并显示错误：

request.rb:67:in `+': no implicit conversion of Request into String (TypeError)
    from request.rb:67:in `addAttachment'
    from tes.rb:9:in `<main>'

代码是：

class Request
  def initialize(id)
     $id = id
  end

   def to_s
      $id.chomp
   end
end

class RequestService < WsApi
   def initialize(environment, user, password)
     @environment = environment
     @user = user
     @password = password

    if @environment == 'staging'
      @uri = 'some url'
    elsif @environment == 'production'
      @uri = ''
    else
      puts 'Enter valid environment - staging / production'
    end
  end

  def getRequest(request_id)
     # define local variables
      req_id = request_id

     begin
     # Create object of ws_api_base class to do a get function on the request_id to check if id exists or not
      obj1 = WsApi.new(@uri, @user, @password)
      restap = obj1.restapi
      response = restap['requests/' + req_id ].get(:username => @user, :password => @password, :accept => 'application/json')

      # Create a request object to set request id as valid cx ticket number
      if response.code === 200
       req_obj = Request.new(req_id)
       return req_obj
     end

     rescue
       puts 'Request id ' + req_id + ' does not exists'
       exit
     end
  end

  def addAttachment(request_id, file_location)
    # define local variables
     req_id = request_id
    file_loc = file_location

    # If request exists proceed with add attachment
    f = Base64.encode64(File.read(file_loc))
    file_size = File.size(file_loc)
    file_name = File.basename(file_loc)
    payload = [{"contentType" => "text/plain","size" => file_size,"fileName" => file_name,"data" => f.chomp}].to_json

     obj1 = WsApi.new(@uri, @user, @password)
     restap = obj1.restapi
     response = restap['requests/' + req_id + '/attachments'].post(payload, :username => @user, :password => @password, :content_type => 'application/json', :accept => 'application/json')
     if response.code === 200
        puts "Attachment added successfuly"
     else
        puts response
     end

   end
end

Answer 1

addAttachment期待String不是对象，您只需要在to_s上调用req_object方法。 Ruby不会为你做那件事。

Answer 2

您可以使用"requests/#{req_id}/attachments"代替'requests/' + req_id + '/attachments'。也许你应该覆盖to_s方法。

Ruby调用对象作为另一个对象内的属性
