生成 WSSE-Header 时使用 Koltin 访问 ORO-Platform API 失败

Question

鉴于此 PHP-file 生成 WSSE-Header 以访问 ORO-Platform API (https://oroinc.com/oroplatform/). Official documentation for building the WSSE-Header: https://oroinc.com/orocrm/doc/2.3/dev-guide/cookbook/how-to-use-wsse-authentication#how-to-use-wsse-authentication

<?php

$userName = 'admin';
$userApiKey = 'dfeeb001cc4b947d8790c906d196d78a41915749';

$nonce = base64_encode(substr(md5(uniqid()), 0, 16));
$created  = date('c');

// Just for test for StakeOverFlow
created = "2019-02-05T14:45:43+01:00"
nonce = "REBxdWVYkSrAADwORS+H5w=="

$digest   = base64_encode(sha1(base64_decode($nonce) . $created . $userApiKey, true));

$wsseHeader = "Authorization: WSSE profile=\"UsernameToken\"\n";
$wsseHeader.= sprintf(
    'X-WSSE: UsernameToken Username="%s", PasswordDigest="%s", Nonce="%s", Created="%s"',
    $userName,
    $digest,
    $nonce,
    $created
);

echo $wsseHeader;

我需要在 Kotlin 中为 Android 应用程序使用相同的逻辑。

到目前为止，这是我的代码

package de.warehouse.prozessio.appwarehouse.manager

import android.util.Base64
import java.util.*
import android.util.Log
import java.security.MessageDigest
import java.text.SimpleDateFormat

class OroAPIManager {
    fun getHeader() {
        val md = MessageDigest.getInstance("SHA-1")

        val user = "admin"
        val key = "dfeeb001cc4b947d8790c906d196d78a41915749"
        var nonce = String(Base64.encode(md.digest(UUID.randomUUID().toString().toByteArray()), 0, 16,0)).dropLast(1)
        var created = SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ", Locale.GERMAN).format(Date())
        created = created.replaceRange(created.length - 2, created.length - 1, ":0")
        // Just for test for Whosebug
        created = "2019-02-06T15:37:11+01:00"
        nonce = "NjA3Yzc4ZjEwY2ZjNTY4NA=="

        val digest = Base64.encode((convertToSha1String(String(Base64.decode(nonce.toByteArray(), Base64.DEFAULT)) + created + key)).toByteArray(), Base64.DEFAULT)
        var wsseHeader = "Authorization: WSSE profile=\"UsernameToken\"\n";
        wsseHeader += "X-WSSE: UsernameToken Username=\"$user\", "
        wsseHeader += "PasswordDigest=\"${String(digest).dropLast(1)}\", "
        wsseHeader += "Nonce=\"$nonce\", "
        wsseHeader += "Created=\"$created\""

        Log.i("data", wsseHeader)
    }

    private fun convertToSha1String(raw: String): String {
        var convertedString = "";
        val bytes = raw.toByteArray()
        val md = MessageDigest.getInstance("SHA-1")
        val digest = md.digest(bytes)
        for (byte in digest) convertedString += "Cn".format(byte)
//        for (byte in digest) convertedString += byte.toChar()
//        for (byte in digest) convertedString += byte.toString()
        Log.i("data", "Converted String: $convertedString")

        return convertedString
    }
}

PHP 脚本的结果是：

X-WSSE: UsernameToken Username="admin", PasswordDigest="fukhjBVWYl0i08iPaLBeXTJkT4U=", Nonce="NjA3Yzc4ZjEwY2ZjNTY4NA==", Created="2019-02-06T15:37:11+01:00"

这是正确的，我可以访问 Oro。

Kotlin 的结果是：

X-WSSE: UsernameToken Username="admin", PasswordDigest="Q25DbkNuQ25DbkNuQ25DbkNuQ25DbkNuQ25DbkNuQ25DbkNuQ25Dbg==", Nonce="NjA3Yzc4ZjEwY2ZjNTY4NA==", Created="2019-02-06T15:37:11+01:00"

这是不正确的。我猜的问题是 raw-Flag for PHP-sha1 函数。当我尝试几种方法将 Bytearray 转换为原始字符串但没有成功时。

Oro-Forum 中的主题如下：https://forum.oroinc.com/oro-platform/how-do-i-questions/topic/generate-api-wss-header-for-kotlin#post-37936。他们那里很友好，但是这次没能提供帮助。

有人知道如何将两个不同的结果放在一起吗？

感谢@Michael Bessolov 为我指明了正确的方向。这是从 Android 和 ORO-API:

import android.content.Context
import android.preference.PreferenceManager
import android.util.Base64
import java.util.*

    fun getHeader(): String {
        val prefs = PreferenceManager.getDefaultSharedPreferences(this.context)
        val user = prefs.getString("oro_user", "<unset>")
        val key = prefs.getString("oro_api_key", "<unset>")

        val uid = UUID.randomUUID().toString();
        val nonce = String(Base64.encode(convertToDigestString(uid, "MD5").toByteArray(), 0, 16,0)).dropLast(1)
        var created = SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ", Locale.GERMANY).format(Date())
        created = created.replaceRange(created.length - 2, created.length - 1, ":0")

        val nonceBase64 = String(Base64.decode(nonce.toByteArray(), Base64.DEFAULT))
        val sha1 = hexToBin(convertToDigestString(nonceBase64  + created + key, "SHA-1"))
        val digest = Base64.encode(sha1.toByteArray(Charset.forName("ISO-8859-1")), Base64.DEFAULT)

        return wsseHeader;
    }

        val bytes = raw.toByteArray()
        val md = MessageDigest.getInstance(digestName)
        val digest = md.digest(bytes)

        val hexChars = "0123456789abcdef"
        val convertedString = StringBuilder(digest.size * 2)

        digest.forEach {
            val i = it.toInt()
            convertedString.append(hexChars[i shr 4 and 0x0f])
            convertedString.append(hexChars[i and 0x0f])
        }

        return convertedString.toString()
    }

    private fun hexToBin(hexStr: String): String {
        val output = StringBuilder("")
        var i = 0
        while (i < hexStr.length) {
            val str = hexStr.substring(i, i + 2)
            output.append(Integer.parseInt(str, 16).toChar())
            i += 2
        }

        return output.toString()
    }
}

Answer 1

我一点也不熟悉 Kotlin，但 convertedString += "Cn".format(byte) 在当今的多字节编码世界中看起来很可疑。以下文章（受 https://www.samclarke.com/kotlin-hash-strings/ 启发）会产生不同的结果吗？

val HEX_CHARS = "0123456789ABCDEF"
val convertedString = StringBuilder(digest.size * 2)

digest.forEach {
    val i = it.toInt()
    convertedString.append(HEX_CHARS[i shr 4 and 0x0f])
    convertedString.append(HEX_CHARS[i and 0x0f])
}
