Node.js からe-Sales Manager 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e-Sales Manager data へのCRUD クエリを実行します。

CData API Server とADO.NET Provider for e-Sales Manager(もしくは200+ の他のADO.NET Providers)を使って、e-Sales Manager 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e-Sales Manager 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 e-Sales Manager 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 e-Sales Manager

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

e セールスマネージャー Remix に接続するには、User、Passowrd、URL、TenantId パラメータが必要です。

  • User: API を実行するためのログインユーザーのユーザーID。
  • Password: API を実行するためのログインユーザーのユーザーパスワード
  • URL: e-Sales Manager Remix エンドポイントへのURL。例:https://XXX.softbrain.co.jp
  • TenantId: e-Sales Manager Remix テナント名のTenantd。例:cdata

You can then choose the e-Sales Manager 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 e-Sales Manager 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 Customer data. The example URL below applies a simple filter that searches for records with a value of CustomerAddress in the Address column.

var http = require('http'); http.get({ protocol: "http:", hostname: "MyServer.com", port: MyPort, path: "/api.rsc/Customer?$filter=" + encodeURIComponent("Address eq 'CustomerAddress'"), 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); });
