加密签名

访问API的签名算法需要添加的Header：

请求头	必填	描述
X-Gw-Signature-Method	是	加密算法，目前只支持 hmac-sha256
X-Gw-Signature-Headers	是	签名所需要的请求头，填写 X-Gw-Timestamp,X-Gw-App-Key
X-Gw-App-Key	是	签名 AppKey，在控制台 App 详情页中获取
X-Gw-Timestamp	是	UNIX 签名时间戳,
X-Gw-SignedString	是	被签名字符串，格式为 “X-Gw-Timestamp:“+签名时间戳+“,X-Gw-App-Key:“+AppKey
X-Gw-Signature	是	签名值
X-Gw-Stage	否	如调用环境为 RELEASE 环境可不填，API 市场中订阅的 API调用可不填

NodeJs 版本签名代码


var axios = require("axios")
var CryptoJS = require("crypto-js");
 
 
var signHeaders = "X-Gw-Timestamp,X-Gw-App-Key"
var appKey = "xxxxxxxxxxxxxxxxxxxx"
var appSecret = "yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy"
 
 
var timeStamp = Math.ceil(Date.now() / 1000)
var signedString = "X-Gw-Timestamp:"+timeStamp+",X-Gw-App-Key:"+appKey;
var signature = CryptoJS.HmacSHA256(signedString , appSecret).toString(CryptoJS.enc.Base64);
 
var url = "http://demo.ucloudapi.com/getUserInfo/v1"
 
axios({
	method : "GET",
	url : url,
	headers : {
		"X-Gw-Signature-Method"  : "hmac-sha256",
		"X-Gw-Signature-Headers" : "X-Gw-Timestamp,X-Gw-App-Key",
		"X-Gw-App-Key"           : appKey,
		"X-Gw-Timestamp"         : timeStamp,
		"X-Gw-Signature"         : signature,
		"X-Gw-SignedString"      : signedString,
		"X-Gw-Stage"             : "RELEASE"
	}
}).then(function(response){
	console.log(response.data)
})
