niftycloud-auth

CAUTION: EXPERIMENTAL CODE

This is the SDK for NIFTY Cloud API to make authentication parameters of API request.

Install

npm install niftycloud-auth

Basic Usage

There is classes that maekes signature parameters for signature version 2 / 3 / 4.

First, you need to create instance of class of signature version that you want to request. Then, you can request api with some parameters. Please visit NIFTY Cloud API Reference page to know about API endpoint, path and required parameters.

All api request method is avaiable both callback (err, res)=>{} and promise chain.

If content type of response is xml, response.body property includes result ofparsing xml by xml2js. Other response parameter is same as Superagent

const NiftyCloud = require("../lib/niftycloud.js");

const v2 = new NiftyCloud.V2(
  "YOUR_ACCESS_KEY",
  "YOUR_SECRET_ACCESS_KEY",
  "https://east-1.cp.cloud.nifty.com"
);

v2.get( "/api/", "DescribeInstances", {}).then((res)=>{
  console.log("res:" + JSON.stringify(res.body));
}).catch((err)=>{
  if (err instanceof v2.ApiError) {
    console.log("err:" + err);
  }
});
