我正在为Rails应用程序构建API。我实际上有两个应用程序：服务器（API）和客户端（与API交互）。我正在尝试通过API调用创建模型对象的post请求。当对象有效时，会创建模型对象但我收到Completed 406 Not Acceptable错误。服务器以静默方式抛出错误，因此返回响应对象。足够的写作/谈话，这里有一些代码：
class Api::V1::RequestsController < Api::V1::BaseController
respond_to :json
def create
respond_with Request.create!(params[:request])
end
end
namespace :api do
scope module: :v1 do
resources :requests, only: [:index, :create]
end
end
class RequestsController < ApplicationController
def new
@request = Request.new
end
def create
@request = Request.new(params[:request])
if response = @request.save
flash[:success] = "Request successfully sent"
p response
redirect_to request_url(@request)
else
render :new
end
end
end
class Request < ActiveRecord::Base
include HTTParty
if Rails.env.development?
base_uri "http://localhost:3000/"
end
def save
if self.valid?
self.class.post("/api/requests", { body: {
request: {
artist_name: self.artist_name,
email: self.email,
phone_number: self.phone_number,
country: self.country,
city: self.city
}
} })
else
false
end
end
end

当我使用cURL来获取获取所有模型对象的get请求时，它完美地运行。当我尝试用cURL做一个POST请求时...好吧它不起作用，因为我没有正确使用cURL而且我不知道如何。
正如Vadim Chumel建议的那样，我通过将.json添加到请求网址来修改了保存方法：
# ...
self.class.post("/api/requests.json", { body: {
# ...
现在我在服务器上遇到500错误（API端）;这是请求的日志：

奇怪的是，在整个服务器项目中，没有提到request_url
答案 0 :(得分：2)
在您期待HTML时，似乎您的api仅响应json。尝试更改此行：
self.class.post("/api/requests", { body: {
为：
self.class.post("/api/requests.json", { body: {
答案 1 :(得分：1)
尝试使用respond_with
设置位置 @request = Request.create(params[:request])
respond_with(@request, :location => nil)
此外，您的客户端需要显示操作，这就是您遇到路由错误的原因
ActionController::RoutingError (No route matches {:action=>"show", :controller=>"requests", :id=>#<Request artist_name: "Knife Party", email: "person@example.com", phone_number: "07949967627", country: "France", city: "Paris">}):
app/controllers/requests_controller.rb:20:in `create'
另外我不明白你如何在客户端保存对象..没有关于设置创建的主键记录的逻辑。
