BitGO-JS超過交易250限制

Question

我試圖模擬與test.bitgo.com的幫助超過250個交易，這是目前的API限制設置...我試過並嘗試了不同的方法來實現同樣的結果和一週後，我仍然無法找到一個合適的方式獲得一個GO中的所有交易數據。

他們的一位開發人員說我可以用一個帶有嵌套while循環的Promise來實現，該Promise添加了count：250來跳過：0並一次又一次地運行該函數，直到沒有什麼可以總結爲止，因爲計數最終爲0，並獲得所有852個事務。

這就是我使用的https://www.bitgo.com/api/#list-wallet-transactions。它返回一個有250個事務的對象，並保持這樣的計數。

var walletId = '2NB96fbwy8eoHttuZTtbwvvhEYrBwz494ov'; 
bitgo.wallets().get({ "id": walletId }, function callback(err, wallet) { 
    if (err) { throw err; } 
wallet.transactions({limit:2, skip:0}, function callback(err, transactions) { 
// handle transactions 
console.log(JSON.stringify(transactions, null, 4)); 
    }); 
}); 

// This is the result

} 

正如你可以看到我有一個總的「總」的：852個交易，跳過參數等於「開始」：0，上限等於「計數」：2

LEGEND ： 限制：250只會顯示總計852個250個交易 跳過：250會跳過前250個交易並開始顯示251> = 500

主要問題是我最多隻能獲得250個交易一次，我試圖將結果推送到一個數組，並在lodash的幫助下連接所有內容，但失敗了。試圖通過大量的請求跳過：250然後500然後750等工作，仍然無法清理和保存一切。

希望有人已經不得不爬上這座山，願意花幾分鐘的時間指引我走向正確的方向。謝謝 ！

你想要的是一個遞歸的異步函數，它爲「skip」重複調用wallet.transactions（{skip：skip}），它允許你遍歷錢包上的所有交易。看看下面的代碼：

var BitGoJS = require('bitgo'); 

var user = 'octavian@l.com'; 
var loginPassword = 'supersecretpassword'; 
var otp = '0000000'; 
var walletId = 'yourWalletId'; 

var bitgo = new BitGoJS.BitGo(); 


var printTxs = function() { 
    // Now get the wallet 
    bitgo.wallets().get({ id: walletId }, function(err, wallet) { 
    if (err) { console.log("Error getting wallet!"); console.dir(err); return process.exit(-1); } 

    var allTxs = []; 

    /** 
    * Fetch transactions from the wallet using skip as an index into the array of all 
    * transactions on the wallet 
    * @param skip {Number} the number of transactions we should skip ahead 
    */ 
    var getTransactionBatch = function(skip, callback) { 
     wallet.transactions({ skip: skip }, function(err, res) { 
     if (err) { console.log("Error getting transactions!"); console.dir(err); return process.exit(-1); } 

     res.transactions.forEach(function(tx) { 
      allTxs.push(tx); 
     }); 

     var totalTxCount = res.total; 

     if (totalTxCount && totalTxCount > allTxs.length) { 
      var newSkip = skip + res.count; // add the number of tx's we just fetched to the number we already skipped ahead 

      return getTransactionBatch(newSkip, callback); 
     } 

     return callback(); 
     }); 
    }; 

    getTransactionBatch(0, function() { 
     console.log('All Transactions\n'); 
     console.log(JSON.stringify(allTxs, null, 2)); 
    }) 
    }); 
}; 

// Authenticate first 
bitgo.authenticate({ username: user, password: loginPassword, otp: otp }, function(err, result) { 
    if (err) { console.dir(err); throw new Error("Could not authenticate!"); } 
    console.log("Unlocking account.."); 
    bitgo.unlock({ otp: otp }, function(err) { 
    if (err) { console.dir(err); throw new Error("Could not unlock!"); } 
    printTxs(); 
    }); 
}); 

一旦你登錄憑據，walletId在適當的值上填寫，此功能將重複調用BitG​​o每次添加它收到的交易響應allTxs陣列。一旦該數組的大小與錢包上的tx總數相等，它將打印出所有的交易。將console.log調用替換爲您希望對事務執行的任何處理，並且您將成爲金牌！
