BitGO – 从对象数组获取帐户和值
我在做什么：
- 当一个新的用户注册一个个人钱包时，在Mongo内部生成并存储它们。
- 后来，我们提出请求，并从Mongo获取所有用户钱包地址，并将它们存储在
allDBWallets。 - 每天生成一个新的钱包，它的地址存储在
walletId。 - 人们从他们唯一的生成地址向
walletId，我们开始logging和分析所有的walletId交易logging。

*我希望达到的是这个*
//第一个TX OBJ例子
{ "account": "2N1mqFS5nDJkPHTvKz1xBFs2LP8LwoKmcBH", // bad address, i need the Users address (2MzppxEX7xMidjhoJGczFDYsHk5TQwFkjS3) not the walletId address "value": 705400000 // real amount is perfect but can't properly compare and extract users address },
希望我find能帮助解释如何validation和提取发送到每日生成地址的用户地址和真实货币的人。
问题是有以下的说法
if (entry.account == allDBWallets[i] && entry.account == walletId) {
条件2（ entry.account == walletId ）只有在entry.account为2N1mqFS5nDJkPHTvKz1xBFs2LP8LwoKmcBH时才为true，在这种情况下，条件1（ entry.account == allDBWallets [i] ）只有在allDBWallets数组有2N1mqFS5nDJkPHTvKz1xBFs2LP8LwoKmcBH 。
而根据上述数据，两种情况都不会同时发生，因此没有得到期望的结果。
因此，您需要更正条件/逻辑以获得所需的输出。
可能的解决scheme
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); } }) } });
