Question

我正在尝试向控制器测试PUT请求，但我需要向操作发送GET和POST正文。 params不能拼凑在一起，因为代码的某些部分明确地访问GET参数。

你如何将GET参数传递给put动作？

我有这个测试：

it "updates the account password to the provided value" do
  put(:update, @params)
  @account.reload.crypted_password.should == PasswordAccount.encrypt(@newpass, @account.password_salt)
end

如何在发送到操作的查询字符串中添加“令牌”参数？

Answer 1

put方法在Rails'ActionController::TestCase::Behavior：

中定义

http://api.rubyonrails.org/classes/ActionController/TestCase/Behavior.html#method-i-put

从我所看到的，不支持分离不同的get / post params，但为什么不将它包含在@params变量中呢？

put(:update, @params.merge(:token => 'gobbledygook'))

当你的代码看到params时，无论如何Rails已经为你合并了get / post params。

更新：

在调查了rails测试源代码之后，我想出了以下内容：

def process_with_query(action, query_string="", parameters = nil, session = nil, flash = nil, http_method = 'GET')
  # Sanity check for required instance variables so we can give an
  # understandable error message.
  %w(@routes @controller @request @response).each do |iv_name|
    if !(instance_variable_names.include?(iv_name) || instance_variable_names.include?(iv_name.to_sym)) || instance_variable_get(iv_name).nil?
      raise "#{iv_name} is nil: make sure you set it in your test's setup method."
    end
  end

  @request.recycle!
  @response.recycle!
  @controller.response_body = nil
  @controller.formats = nil
  @controller.params = nil

  @html_document = nil
  @request.env['REQUEST_METHOD'] = http_method

  parameters ||= {}
  @request.assign_parameters(@routes, @controller.class.name.underscore.sub(/_controller$/, ''), action.to_s, parameters)

  @request.session = ActionController::TestSession.new(session) unless session.nil?
  @request.session["flash"] = @request.flash.update(flash || {})
  @request.session["flash"].sweep

  @controller.request = @request
  @controller.params.merge!(parameters)
  build_request_uri(action, parameters)
  @request.env["QUERY_STRING"] = query_string.kind_of?(Hash) ? query_string.to_param : query_string
  @request.env["action_dispatch.request.query_parameters"] = Rack::Utils.parse_query(@request.env["QUERY_STRING"])
  ActionController::Base.class_eval { include ActionController::Testing }
  @controller.process_with_new_base_test(@request, @response)
  @request.session.delete('flash') if @request.session['flash'].blank?
  @response
end

def put_with_query(action, query_string="", parameters=nil, session=nil, flash=nil)
  process_with_query(action, query_string, parameters, session, flash, 'PUT')
end

def post_with_query(action, query_string="", parameters=nil, session=nil, flash=nil)
  process_with_query(action, query_string, parameters, session, flash, 'POST')
end

有任何意见吗？

Rspec将GET参数传递给PUT动作
