我知道标题有点模糊，但我不知道该放什么。 我正在使用Sinatra开发一个用于Ruby后端的API。问题是我需要能够将JSON传递给代表用户的服务。 我面临的问题是，当我运行我的测试时它不起作用，但是对它所做的服务进行手动操作。我猜测JSON格式存在问题。
我已经更新了我的用户模型，以依赖ActiveModel中的帮助程序进行JSON序列化。我在手动转换时遇到了太多问题。这就是基本用户模型的样子：
class User
include ActiveModel::Serializers::JSON
attr_accessor :login, :email, :birthday, :created_at, :updated_at, :password_sha, :password_salt
# Creates a new instance of the class using the information stored
# in the hash. If data is missing then nill will be assigned to the
# corresponding property.
def initialize(params = {})
return if params.nil?
self.login = params[:login] if params.key?("login")
self.email = params[:email] if params.key?("email")
self.birthday = Time.parse(params[:birthday]) rescue Time.now
if params.key?("password_salt") && params.key?("password_sha")
self.password_salt = params["password_salt"]
self.password_sha = params["password_sha"]
elsif params.key?("password")
self.set_password(params[:password])
end
self.created_at = Time.now
end
def attributes
{:login => self.login, :email => self.email, :birthday => self.birthday, :created_at => self.created_at, :updated_at => self.updated_at, :password_sha => self.password_sha, :password_salt => self.password_salt}
end
def attributes=(params = {})
self.login = params['login']
self.email = params['email']
self.birthday = params['birthday']
self.created_at = params['created_at']
self.updated_at = params['updated_at']
self.password_sha = params['password_sha']
self.password_salt = params['password_salt']
end
end
我正在使用Cucumber，Rack :: Test和Capybara来测试我的API实现。 API应用程序的代码如下所示：
# This action will respond to POST request on the /users URI,
# and is responsible for creating a User in the various systems.
post '/users' do
begin
user = User.new.from_json(request.body.read)
201
rescue
400
end
end
在上面的文章中，我期望请求体中的json表示。 由于某种原因，params哈希在这里是空的，不知道为什么 制作实际帖子的测试部分如下所示：
When /^I send a POST request to "([^\"]*)" with the following:$/ do |path, body|
post path, User.new(body.hashes.first).to_json, "CONTENT_TYPE" => "application/json"
end
User.rb文件生成的示例输出JSON字符串如下所示：
"{"user":{"birthday":"1985-02-14T00:00:00+01:00","created_at":"2012-03-23T12:54:11+01:00","email":"arne.de.herdt@gmail.com","login":"airslash","password_salt":"x9fOmBOt","password_sha":"2d3afc55aee8d97cc63b3d4c985040d35147a4a1d312e6450ebee05edcb8e037","updated_at":null}}"
输出是从Rubymine IDE复制的，但是当我将其提交给应用程序时，我无法解析它，因为：
