使用 golang 和 JS 生成时授权字符串不相同

Question

我在使用 Golang 为 API 访问生成正确的授权字符串时遇到问题。我尝试使用 JS，字符串可以使用，而来自 golang 的字符串不能用于身份验证。你能帮我检查一下有什么不同并纠正我吗？这是我的 golang 代码：

func generateSalt(dataToSign string) string {
    token := hmac.New(sha256.New, []byte("secret"))
    token.Write([]byte(dataToSign))
    macSum := token.Sum(nil)
    return base64.StdEncoding.EncodeToString(macSum)
}

func main() {
    date = "Wed, 25 May 2022 09:16:45 GMT"
    uri := "groups"
    url := fmt.Sprintf("https://api-worldcheck.refinitiv.com/v2/%s", uri)
    dataToSign := fmt.Sprintf(`(request-target): get %s%vhost: %s%vdate: %s`, "/v2/groups", "\r\n", "api-worldcheck.refinitiv.com", "\r\n", date)
    log.Printf("dateToSign: %s", dataToSign)
    hmac := generateSalt(dataToSign)
    authorization := fmt.Sprintf(`Signature keyId="%s",algorithm="hmac-sha256",headers="(request-target) host date",signature="%s"`, "api-key", hmac)
    log.Printf("authorization: %s", authorization)
}

golang的结果是dZzRZfa0yVZsTWof+qEz5VhsFyV83b6DDKXzG9pp/yk=

JS上的代码

function generateAuthHeader(dataToSign){
    var hash = CryptoJS.HmacSHA256(dataToSign,environment["api-secret"]);
    return hash.toString(CryptoJS.enc.Base64); 
}

var date = "Wed, 25 May 2022 09:16:45 GMT";

var dataToSign = "(request-target): get " + environment["gateway-url"] + "groups\n" +
        "host: " + environment["gateway-host"] + "\n" +
        "date: " + date;
        console.log("date", date)
        console.log({dataToSign})
var hmac = generateAuthHeader(dataToSign);
var authorisation = "Signature keyId=\"" + environment["api-key"] + "\",algorithm=\"hmac-sha256\",headers=\"(request-target) host date\",signature=\"" + hmac + "\"";
        console.log({authorisation})

结果为nx5uyMlq4kOxY1fD5OpoLE6UGI+f5p3OUy+l6G8+oxc=

两个片段都有不同的数据要签名。 JS 有一些使用的环境变量可能不同。我从 Go 代码中获取了这些值。

转码：Go Playground example

// You can edit this code!
// Click here and start typing.
package main

import (
    "crypto/hmac"
    "crypto/sha256"
    "encoding/base64"
    "fmt"
    "log"
)

func generateSalt(dataToSign string) string {
    token := hmac.New(sha256.New, []byte("secret"))
    token.Write([]byte(dataToSign))
    macSum := token.Sum(nil)
    return base64.StdEncoding.EncodeToString(macSum)
}

func main() {
    date := "Wed, 25 May 2022 09:16:45 GMT"
    uri := "groups"
    url := fmt.Sprintf("https://api-worldcheck.refinitiv.com/v2/%s", uri)
    host := "api-worldcheck.refinitiv.com"
    dataToSign := fmt.Sprintf("(request-target): get %s\nhost: %s\ndate: %s", url, host, date)
    log.Printf("dateToSign: %s", dataToSign)
    hmac := generateSalt(dataToSign)
    authorization := fmt.Sprintf(`Signature keyId="%s",algorithm="hmac-sha256",headers="(request-target) host date",signature="%s"`, "api-key", hmac)
    log.Printf("authorization: %s", authorization)
}

JS代码：

function generateAuthHeader(dataToSign){
    var hash = CryptoJS.HmacSHA256(dataToSign, "secret");
    return hash.toString(CryptoJS.enc.Base64); 
}

var date = "Wed, 25 May 2022 09:16:45 GMT";
var url = "https://api-worldcheck.refinitiv.com/v2/";
var host = "api-worldcheck.refinitiv.com";
var apiKey = "api-key";

var dataToSign = "(request-target): get " + url + "groups\n" +
        "host: " + host + "\n" +
        "date: " + date;
console.log("date", date)
console.log("dataToSign", dataToSign)
var hmac = generateAuthHeader(dataToSign);
var authorisation = "Signature keyId=\"" + apiKey + "\",algorithm=\"hmac-sha256\",headers=\"(request-target) host date\",signature=\"" + hmac + "\"";
console.log(authorisation);

使用 golang 和 JS 生成时授权字符串不相同

Authorization string is not same when generate with golang and JS

node.js

go

authentication

cryptography

cryptojs
