[英]Rails: Post JSON to API Using Rails and HTTParty
我对Rails中的API相当陌生,因此我将需要一些帮助来解决我面临的问题。
我只想通过我的应用程序发出的POST请求在API数据库上创建一条记录。
那就是每当我创建一本书时,都要在两个数据库(我的数据库和API的数据库上通过来自我的应用程序的POST请求)上创建一条记录。
因此,这是我到目前为止所做的:
对于将使用API的应用程序,我正在使用HTTParty gem 。
我尝试使用以下代码在Books Controller的create动作中实现:
@result = HTTParty.post(' https://www.pingme.com/wp-json/wplms/v1/user/register',
:body => { :name => '#{name}',
:author => '#{author}',
:description => '#{description}',
:category_id => '#{category_id}',
:sub_category_id => '#{sub_category_id}'}.to_json,
:headers => { 'Content-Type' => 'application/json', 'Authorization' => '77d22458349303990334xxxxxxxxxx' })
这是我的用于创建图书的图书控制器
require 'httparty'
class BooksController < ApplicationController
include HTTParty
before_action :set_book, only: [:show, :edit, :update, :destroy]
before_action :authenticate_admin!, except: %i[show index]
skip_before_action :verify_authenticity_token
# GET /books
# GET /books.json
def index
@books = Book.search(params[:keywords]).paginate(:page => params[:page], :per_page => 9).order('created_at DESC')
end
# GET /books/1
# GET /books/1.json
def show
end
# GET /books/new
def new
@book = Book.new
end
# GET /books/1/edit
def edit
end
# POST /books
# POST /books.json
def create
@book = Book.new(book_params)
respond_to do |format|
if @book.save
format.html { redirect_to @book, notice: 'Book was successfully created.' }
format.json { render :show, status: :created, location: @book }
else
format.html { render :new }
format.json { render json: @book.errors, status: :unprocessable_entity }
end
end
@result = HTTParty.post(' https://www.pingme.com/wp-json/wplms/v1/user/register',
:body => { :name => '#{name}',
:author => '#{author}',
:description => '#{description}',
:category_id => '#{category_id}',
:sub_category_id => '#{sub_category_id}'}.to_json,
:headers => { 'Content-Type' => 'application/json', 'Authorization' => '77d22458349303990334xxxxxxxxxx' })
end
# PATCH/PUT /books/1
# PATCH/PUT /books/1.json
def update
respond_to do |format|
if @book.update(book_params)
format.html { redirect_to @book, notice: 'Book was successfully updated.' }
format.json { render :show, status: :ok, location: @book }
else
format.html { render :edit }
format.json { render json: @book.errors, status: :unprocessable_entity }
end
end
end
# DELETE /books/1
# DELETE /books/1.json
def destroy
@book.destroy
respond_to do |format|
format.html { redirect_to books_url, notice: 'Book was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_book
@book = Book.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def book_params
params.require(:book).permit(:name, :author, :description, :category_id, :sub_category_id)
end
end
但是当我创建书籍时,它仍然不会通过发布请求在API的数据库上创建这些书籍。
请任何形式的协助将不胜感激。 谢谢。
在执行请求时检查您的日志,但我怀疑您需要将身体更改为:
{
:book => {
:name => '#{name}',
:author => '#{author}',
:description => '#{description}',
:category_id => '#{category_id}',
:sub_category_id => '#{sub_category_id}'
}
}.to_json
请注意,顶部的book
钥匙是不同的。
在@ paulo-fidalgo和@tejasbubane的贡献之后,我找到了解决该问题的可行方法。
这是更正后的HTTParty发布请求
@results = HTTParty.post(' https://www.pingme.com/wp-json/wplms/v1/user/register',
:body => {
:name => "#{@book.name}",
:author => "#{@book.author}",
:description => "#{@book.description}",
:category_id => "#{@book.category_id}",
:sub_category_id => "#{@book.sub_category_id}"}.to_json,
:headers => {
'Content-Type' => 'application/json',
'Authorization' => '77d22458349303990334xxxxxxxxxx'
}
)
就这样
我希望这有帮助。
