尝试使用Node JS设置API Management REST API身份验证

Question

我的目标是使用Azure API Management API验证Node.js客户端。

我正在努力将这个C＃示例转换为Node.js Javascript。我已经使用自己的ID和密钥测试了C＃示例，似乎使用API​​对200进行了身份验证，但我一直在使用我的Node.js代码段获得401。

我觉得它可能与C＃示例格式化到期（ex={1:o}）的方式有关，这是Format Specifier

的类型

using System;   
using System.Text;   
using System.Globalization;   
using System.Security.Cryptography;   

public class Program   
{   
    public static void Main()   
    {   
        var id = "12345678abcdefgh";   
        var key = "1234abcd5678asdf==";   
        var expiry = DateTime.UtcNow.AddDays(10);   
        using (var encoder = new HMACSHA512(Encoding.UTF8.GetBytes(key)))   
        {   
            var dataToSign = id + "\n" + expiry.ToString("O", CultureInfo.InvariantCulture);   
            var hash = encoder.ComputeHash(Encoding.UTF8.GetBytes(dataToSign));   
            var signature = Convert.ToBase64String(hash);   
            var encodedToken = string.Format("SharedAccessSignature uid={0}&ex={1:o}&sn={2}", id, expiry, signature);   
            Console.WriteLine(encodedToken);   
        }   
    }   
}

My Node.js Snippet

var util = require('util')
var crypto = require('crypto')
var generateAccessCode = function() {
    var id = "1234asdf1234asdf";
    var key = "1234asdf1234ghjk";
    const accessCodeExpireDays = 10;
    const formatString = 'SharedAccessSignature uid=%s&ex=%s&sn=%s'
    const dataToSignString = '%s\n%s';

    //create expiry string
    var today = new Date();
    var expiry = new Date();
    expiry.setDate(today.getDate() + accessCodeExpireDays);
    expiry = expiry.toISOString();

    //create hash
    var dataToSign = util.format(dataToSignString, id, expiry)
    const hash = crypto.createHmac('sha512', key)
        .update(dataToSign)
        .digest('base64');

    var encodedToken = util.format(formatString, id, expiry, hash);

    console.log(encodedToken)
}

generateAccessCode()

您可能需要通过Moment.js

格式化到期日期，如下所示

//create expiry string
var today = new Date();
var expiry = new Date();
expiry.setDate(today.getDate() + accessCodeExpireDays);
expiry = moment(expiry).format('YYYY-MM-DD[T]HH:mm:ss.SSSSSSS[Z]')
