在云函数中处理HTTP请求时读取ECONNRESET错误

Question

我正在尝试向Firebase云函数中的App Store verifyReceipt端点发送一个post请求。然而，我在云功能日志中得到以下错误：

{ Error: read ECONNRESET
at TLSWrap.onread (net.js:622:25)
errno: 'ECONNRESET',
code: 'ECONNRESET',
syscall: 'read',

然而，这种错误只是偶尔发生的。它不是每次都发生，所以这个功能显然有效，但有时会出现问题，我不确定是什么。

与此相关的大多数其他解决方案都是由于承诺错误，但我不认为这是问题所在。以下是完整的功能：

exports.handleSubscriptionIAP_IOS_S2S = functions.https.onRequest((req, res) => {
let data = req.body;
console.log('received ios s2s notification with body:', data);
let base64String = data.unified_receipt.latest_receipt;
let boolStatus = true;
// The user has changed the auto renewal status, store the change
if(data.notification_type === 'DID_CHANGE_RENEWAL_STATUS') {
boolStatus = (data.auto_renew_status === 'true');
}
console.log(data.notification_type);
if(base64String) {
var options = {
method: 'post',
url: 'https://buy.itunes.apple.com/verifyReceipt',
data: ({
"receipt-data" : base64String,
"password" : "***",
"exclude-old-transactions" : true
})
};
var optionsSandbox = {
method: 'post',
url: 'https://sandbox.itunes.apple.com/verifyReceipt',
data: ({
"receipt-data" : base64String,
"password" : "***",
"exclude-old-transactions" : true
})
};
return axios(options)
.then((response) => {
if(response.data.status === 21007) {
return 'handle_sandbox';
}
// Got valid response from Apple, pass down chain
else {
return response;
}
})
.then((response) => {
// Send post request to sandbox endpoint
if(response === 'handle_sandbox') {
return axios(optionsSandbox);
}
// Pass response down chain
else {
return response;
}
})
.then((response) => {
// Handle response from Apple verifyReceipt endpoint here
// Both production and sandbox will end up here
// See here for values in response.data: https://developer.apple.com/documentation/appstorereceipts/responsebody/latest_receipt_info
console.log('received ios s2s notification verify receipt response with body:', response.data);
// Status 0 means request is valid
if(response.data.status === 0) {
// Get receipt info of latest receipt
// Only one object in array is return since we exclude old transactions
let latestReceipt = response.data.latest_receipt_info[0];
// Save receipt into Firestore
return db.collection('appStoreReceipts').doc(latestReceipt.original_transaction_id).set({
latest_receipt_info: latestReceipt,
expiresTimestamp: admin.firestore.Timestamp.fromMillis(parseInt(latestReceipt.expires_date_ms)),
originalTransactionID: latestReceipt.original_transaction_id,
autoRenewStatus: boolStatus,
base64Receipt: response.data.latest_receipt,
}, { merge: true });
}
else {
return null;
}
})
.then((result) => {
if(result) {
return res.status(200).end();
}
else {
return res.status(400).end();
}
})
.catch((error) => {
console.log('an error occured handling the subscription', error);
return res.status(400).end();
})
}
else {
console.log('invalid receipt', data);
return res.status(400).end();
}
});

谢谢你能提供的任何帮助！

ECONNRESET只是意味着连接的另一端关闭了它。这可能意味着很多事情。这可能不是你的代码的错，除非你在这个请求中做了太糟糕的事情，以至于苹果决定关闭连接。如果你认为他们做得不对，你应该直接联系他们的支持。
