Question

由于某种原因，我无法从JS中的私钥创建签名。使用谷歌的在线帮助：

https://m4b-url-signer.appspot.com/

URL：https://google.maps.com/maps/api/geocode/json?address=New+York&client=test

示例键（为练习目的而假）密钥：QNade5DtdJKKZbidTsrIgONupc4 =

（结果）签名：XDsiH5JAY7kJLgA1K2PWlhTdO1k =

但是，我的javascript代码：

var keyString = 'QNade5DtdJKKZbidTsrIgONupc4=';
    console.log(keyString)

var urlString = encodeURIComponent('/maps/api/geocode/json?address=New+York&client=test');
console.log(urlString)

// We need to decode private key to binary
var decoded_key_words = CryptoJS.enc.Utf8.parse(keyString);
var decoded_key = CryptoJS.enc.Base64.stringify(decoded_key_words);

console.log(decoded_key);

var signature = CryptoJS.HmacSHA1(decoded_key,urlString);
console.log(signature);

//  Encode binary signature to base 64
var encoded_signature = CryptoJS.enc.Base64.stringify(signature);
console.log(encoded_signature)

给我一个签名：

bOenVNeXI6xI1xlSa77oqGKssyY =

我似乎无法弄清楚我做错了什么。我是否错误地解码了base64？

Answer 1

为了记录，这有效：

<script src="sha.js"></script>

var url = '/maps/api/geocode/json?address=New+York&client=test';
var key = 'QNade5DtdJKKZbidTsrIgONupc4='

var hmacObj = new jsSHA(url, 'TEXT');
var hmacOutput = hmacObj.getHMAC(key,'B64','SHA-1','B64');

console.log(hmacOutput)

给我：

XDsiH5JAY7kJLgA1K2PWlhTdO1k =

使用Javascript签署密钥HMAC SHA1
