我在做什么:
- 当新用户注册时，会在 Mongo 中为他们生成并存储一个个人钱包。
- 之后我们发出请求并从 Mongo 获取所有用户钱包地址并将它们存储在
allDBWallets中。 - 每天都会生成一个新钱包，它的地址存储在
walletId中。 - 人们从他们生成的唯一地址向
walletId汇款，我们开始记录和分析所有walletId交易历史。
// Check if a wallet has new transactions
var allTransactions = [

最佳答案
问题出在下面的语句
if (entry.account == allDBWallets[i] && entry.account == walletId) {
条件 2 (entry.account == walletId) 仅当 entry.account 为 2N1mqFS5nDJkPHTvKz1xBFs2LP8LwoKmcBH 时为真，在这种情况下条件1 (entry.account == allDBWallets[i]) 仅当 allDBWallets 数组具有 2N1mqFS5nDJkPHTvKz1xBFs2LP8LwoKmcBH 的条目时为真。
并且根据上述数据，这两个条件永远不会同时为真，因此不会得到预期的结果。
因此，您需要更正条件/逻辑以获得所需的输出。
可能的解决方案
allTransactions.forEach(function(transaction){
// Check whether there is an entry from any of the wallets in allDBWallets
var wallet = transaction.entries.find(function(entry){
return allDBWallets.indexOf(entry.account) > -1;
});
// If an entry exists, then find entries for walletId and paint
if(wallet) {
transaction.entries.forEach(function(entry){
if (entry.account == walletId) {
console.log(wallet.account, entry.value);
}
})
}
});
