Node.js からShopify Data をクエリ

API Server は、データを外部に公開します。CData API Server のOData エンドポイントを使って、Node.js からShopify data へのCRUD クエリを実行します。

CData API Server とADO.NET Provider for Shopify(もしくは200+ の他のADO.NET Providers)を使って、Shopify をOData エンドポイントして公開し、Node.js からシンプルなHTTP リクエストでクエリを実現します。本記事ではAPI Server を使ってJSON でフォーマットされたShopify データをNode.js でリクエストする方法を説明します。

Set Up the API Server

Follow the steps below to begin producing secure Shopify OData services:

Deploy

The API Server runs on your own server. On Windows, you can deploy using the stand-alone server or IIS. On a Java servlet container, drop in the API Server WAR file. See the help documentation for more information and how-tos.

The API Server is also easy to deploy on Microsoft Azure, Amazon EC2, and Heroku.

Connect to Shopify

After you deploy the API Server and the ADO.NET Provider for Shopify, provide authentication values and other connection properties needed to connect to Shopify by clicking Settings -> Connections and adding a new connection in the API Server administration console.

To make use of all the features of the data provider, provide the AppId, Password, and ShopUrl connection properties.

To obtain these values, see the Getting Started section in the help documentation to register the data provider as an application with Shopify.

You can then choose the Shopify entities you want to allow the API Server access to by clicking Settings -> Resources.

Authorize API Server Users

After determining the OData services you want to produce, authorize users by clicking Settings -> Users. The API Server uses authtoken-based authentication and supports the major authentication schemes. Access can also be restricted based on IP address; all IP addresses except the local machine are restricted by default. You can authenticate as well as encrypt connections with SSL.

Consume Shopify OData Feeds from Node.js

OData feeds are easy to work with in Node.js. You can use the HTTP client in Node.js to request JSON-formatted data from the API Server's OData endpoint. After making the request, you can construct the body of the response and call the JSON.parse() function to parse it into records.

The code below will make an authenticated request for Customers data. The example URL below applies a simple filter that searches for records with a value of jdoe1234 in the FirstName column.

var http = require('http'); http.get({ protocol: "http:", hostname: "MyServer.com", port: MyPort, path: "/api.rsc/Customers?$filter=" + encodeURIComponent("FirstName eq 'jdoe1234'"), auth: 'MyUser:MyAuthtoken' }, function(res) { var body = ''; res.on('data', function(chunk) { body += chunk; }); res.on('end', function() { console.log(body); var jsonData = JSON.parse(body); }); }).on('error', function(e) { console.log("Error: ", e); });
