我已成功将Playstore中的Playstore添加到我的Android应用程序中。我正在尝试在我的节点js服务器上验证它。因此,在成功购买后,我将这些购买详细信息发送到我的Firebase数据库。然后根据https://emuneee.com/blog/2015/07/15/google-play-in-app-billing-server-purchase-verification/
我试过以下代码..
var crypto = require('crypto');
var publicKey = "PUBLIC_KEY";
var signedData = {"orderId":"ORDER_ID","packageName":"com.example.app","productId":"id","purchaseTime":1522843791366,"purchaseState":0,"purchaseToken":"something"};
var signature = "signature";
var wasVerified = verifyPurchase(publicKey, signedData, signature);
function verifyPurchase(publicKey, signedData, signature) {
var decodedPublicKey = getPublicKey(publicKey);
var verifier = crypto.createVerify('SHA1');
verifier.update(signedData);
return verifier.verify(decodedPublicKey, signature, 'base64');
}
function getPublicKey(publicKey) {
if (!publicKey) {
return null;
}
var key = chunkSplit(publicKey, 64, '\n');
var pkey = '-----BEGIN PUBLIC KEY-----\n' + key + '-----END PUBLIC KEY-----\n';
return pkey;
}
function chunkSplit(str, len, end) {
len = parseInt(len, 10) || 76;
if (len < 1) {
return false;
}
end = end || '\r\n';
return str.match(new RegExp('.{0,' + len + '}', 'g')).join(end);
}
但得到了这个错误,
crypto.js:99
this._handle.update(data, encoding);
^
TypeError: Data must be a string or a buffer
at Verify.update (crypto.js:99:16)
然后我试了一下
https://www.googleapis.com/androidpublisher/v2/applications/packageName/purchases/subscriptions/subscriptionId/tokens/token
但是获得身份验证错
但我对如何验证感到困惑..需要帮助:(
该错误可以准确地告诉您问题所在。
"Data must be a string or buffer at Verify.update"
。所以你知道你用不是字符串或缓冲区的东西调用Verify.update()
。
你在叫什么?那么根据你的代码,你打电话给verify.update(signedData)
。所以signedData
不是String或缓冲区。
它是什么?那么根据你的源代码:
var signedData = {"orderId":"ORDER_ID","packageName":"com.example.app","productId":"id","purchaseTime":1522843791366,"purchaseState":0,"purchaseToken":"something"};
啊哈!这是将对象分配给signedData,而不是String(或缓冲区)。如果你转到你链接到的教程,你可以在他们的示例代码中看到,他们分配了一个String
。
因此,您可以通过执行此操作来修复此错误消息(额外的引号使其成为字符串):
var signedData = '{"orderId":"ORDER_ID","packageName":"com.example.app","productId":"id","purchaseTime":1522843791366,"purchaseState":0,"purchaseToken":"something"}';
但是如果你仔细阅读错误信息,你的进展会更快 - 他们通常会用一点思考来解释这个问题。
