我正在通过邮递员进行GET请求以访问公司 http://localhost:3000/api/v1/company / 1
刚刚在公司控制器中添加了一个方法：
module Api
module V1
class CompaniesController < ApplicationController
def index
@companies = Company.order('created_at DESC');
render json: { status: 'SUCCESS', message:'Loaded companies', data:@companies }, status: :ok
end
def show
@companies = Company.find(params[:id])
render json: { status: 'SUCCESS', message:'Loaded company', data:@companies }, status: :ok
end
end
end
end
我的日志如下所示：

=> Rails 5.1.3 application starting in development on http://localhost:3000

ActionController :: RoutingError（没有路由匹配[GET] “/ API / V1 /公司％20/1”）：
您的路线在companies之后有空格，导致该错误。确保您的路线不包含空间。它应该看起来像
"/api/v1/companies/1"
