我正在做一个Rails应用程序,它主要是一个API。我正在尝试为我的API端点测试控制器。我的RSpec Controller测试仪如下:
require 'rails_helper'
require 'spec_helper'
require 'rack/test'
require 'devise'
class RoutesControllerTest < ActionController::TestCase
describe "User with token"
test "should post route" do
params = { route: { start_lat: 38.7627951, start_long: -9.1532211,
end_lat: 38.7483783, end_long: -9.155045,
flag_opt: 0.4, city: 1 }
}
post '/routes.json' , params.to_json, format: :json
assert_response :success
end
end
end
我的控制器是:
class RoutesController < ApplicationController
def create
city = City.find(params[:route][:city])
user = current_user
@route = user.routes.new(route_params)
@results = @route.calc_route(@route.start_long, @route.start_lat, @route.end_long, @route.end_lat, params[:route][:flag_opt], city)
if @route.save!
render :template=>"/routes/routes.json.jbuilder", status: 201, :formats => [:json]
else
render json: @route.errors
end
end
private
def route_params
json_params = ActionController::Parameters.new( JSON.parse(request.body.read) )
json_params.require(:route).permit(
:start_lat,
:start_long,
:end_lat,
:end_long,
:flag_opt
)
end
end
但每次我运行rspec spec/controller
时我都会遇到以下错误:
Failure/Error: json_params = ActionController::Parameters.new(JSON.parse(request.body.read) )
JSON::ParserError:
757: unexpected token at 'route%5Bcity%5D=24&route%5Bend_lat%5D=41.26171490000001&route%5Bend_long%5D=-8.38193640000001&route%5Bflag_opt%5D=1&route%5Bstart_lat%5D=38.753225&route%5Bstart_long%5D=-9.144376&route%5Buser_id%5D=24'
这意味着请求不是作为JSON发送的

我也一直在努力挣扎。有时您真的只想用一个真实的JSON主体进行测试。我不确定该解决方案是否特定于Rails 5,但是经过大量的探索,我终于松了一口气,终于找到了解决方案。
您可以使用as: :json
代替format: :json
使RSpec格式化请求正文。
也就是说,更改:
post '/routes.json' , params.to_json, format: :json
到
post '/routes.json' , params.to_json, as: :json

我很好奇你为什么要做json_params = ActionController::Parameters.new( JSON.parse(request.body.read)
? (我错过了什么吗?)
params应该已经作为ActionContoller :: Parameters进入。所以,route_params应该是
def route_params
params.require(:route).permit(
:start_lat,
:start_long,
:end_lat,
:end_long,
:flag_opt
)
end
顺便说一下,我假设您的routes.rb类似于
# config/routes.rb
Rails.application.routes.draw do
namespace :api, defaults: {format: 'json'} do
...
end
end

这对我来说测试了发布到控制器上的json(RSpec 3.7.0)
post :action, params: { whatever: value }, body: { some_key: value }.to_json, as: :json
然后您使用以下命令读取了控制器
request.body.read

您需要将JSON解析设置为您的测试环境。
在spec / support / request_helper.rb中创建一个文件:
module Requests
module JsonHelpers
def json
@json ||= JSON.parse(response.body)
end
end
end
RSpec.configure do |config|
config.include Requests::JsonHelpers, type: :controller
end
并且

我不确定为什么你的API必须在其创建动作中接收json。这就是我要做的事情:
var domain = ConfigurationManager.AppSettings["GlimpseVersionCheckAPIDomain"];
if (string.IsNullOrEmpty(domain))
{
domain = "getGlimpse.com";
}
return new CacheControlDecorator(OneDay, CacheSetting.Public, new RedirectResourceResult(@"//" + domain + "/Api/Version/Check{?packages*}{&stamp}{&callback}", data));
然后在你强大的参数中:
class RoutesControllerTest < ActionController::TestCase
describe "User with token"
test "should post route" do
params = { route: { start_lat: 38.7627951, start_long: -9.1532211,
end_lat: 38.7483783, end_long: -9.155045,
flag_opt: 0.4, city: 1 }
}
count = Route.all.size
post :create, params
expect(response).to have_http_status(201)
expect(Route.all.size).to eq(count + 1) # actually created something
end
end
end
即使在rails端也不需要像JSON一样处理所有内容。

对于Rails 5,只需在HTTP动词之前调用request.accept = "application/json"
。示例:
context "GET #show" do
it "returns json data" do
request.accept = "application/json"
get :show
hash_body = JSON.parse(response.body)
#### your expectation here
end
end
