android - 无法使用 Google Cloud Translation API 限制 API key

Question

要使用 google translate api 我已经创建了 API key ，当我使用下面的代码时我没有问题:

private String translateText(String toTrasnlate){
TranslateOptions options = TranslateOptions.newBuilder()
        .setApiKey("XXXXXXXXXXXXXXXXXXXXX_XXXXXXXX")
        .build();
Translate translate = options.getService();
Translation translation = translate.translate(toTrasnlate, Translate.TranslateOption.targetLanguage("en"));
return translation.getTranslatedText();
}

但是当我在谷歌开发者控制台中使用 SHA1 key 和包添加限制时，我跳过了以下错误，你知道为什么会这样吗？我可以在哪里继续？。问候和感谢。

现在可能为时已晚，但这是完成的方式:

val headers: Map<String, String> = ImmutableMap.of(
            "X-Android-Package", context.packageName,
            "X-Android-Cert", (getApplicationSignature(context)[0])
    )

val options = TranslateOptions.newBuilder()
            .setApiKey(apiKey)
            .setHeaderProvider { headers }
            .build()

并获取 SHA1:

fun getApplicationSignature(context: Context, packageName: String = context.packageName): List<String> {
val signatureList: List<String>
try {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
        // New signature
        val sig = context.packageManager.getPackageInfo(packageName, PackageManager.GET_SIGNING_CERTIFICATES).signingInfo
        signatureList = if (sig.hasMultipleSigners()) {
            // Send all with apkContentsSigners
            sig.apkContentsSigners.map {
                val digest = MessageDigest.getInstance("SHA1")
                digest.update(it.toByteArray())
                bytesToHex(digest.digest())
            }
        } else {
            // Send one with signingCertificateHistory
            sig.signingCertificateHistory.map {
                val digest = MessageDigest.getInstance("SHA1")
                digest.update(it.toByteArray())
                bytesToHex(digest.digest())
            }
        }
    } else {
        val sig = context.packageManager.getPackageInfo(packageName, PackageManager.GET_SIGNATURES).signatures
        signatureList = sig.map {
            val digest = MessageDigest.getInstance("SHA1")
            digest.update(it.toByteArray())
            bytesToHex(digest.digest())
        }
    }

    return signatureList
} catch (e: Exception) {
    // Handle error
}
return emptyList()
}



fun bytesToHex(bytes: ByteArray): String {
    val hexArray = charArrayOf('0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F')
    val hexChars = CharArray(bytes.size * 2)
    var v: Int
    for (j in bytes.indices) {
        v = bytes[j].toInt() and 0xFF
        hexChars[j * 2] = hexArray[v.ushr(4)]
        hexChars[j * 2 + 1] = hexArray[v and 0x0F]
    }
    return String(hexChars)
}
