如何通過 web3.js (0.20.6) 獲取令牌交易歷史

設置

node.js + web3.js (0.20.6 版本) + 並使用 infura 作為 httpProvider

我已經弄清楚並使用 web3.js 成功發送了 erc20 令牌，（經過大量Google搜尋……在這裡完成 noobie……）

我現在正試圖弄清楚如何獲取特定地址的令牌交易歷史。

我知道我需要觀看事件，對於令牌交易，這將是“轉移”事件。

所以我正在關注“契約事件”的 Javascript-API https://github.com/ethereum/wiki/wiki/JavaScript-API#contract-events

下面是我正在執行的程式碼（或至少試圖）

var Web3 = require('web3');
var web3 = new Web3(new Web3.providers.HttpProvider('https://rinkeby.infura.io/MYINFURATOKEN'));

var myaddress = "0x482d42bc7a5dd62f3fae88c3b4cde29a333cf913";

var contractAddress = "0x31a86307bfe81780a47fe98c192004ccdce8fcc0";

var abi = [{"constant":true,"inputs":[],"name":"name","outputs":[{"name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"totalSupply","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"decimals","outputs":[{"name":"","type":"uint8"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[],"name":"enableTokenTransfer","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"name":"_value","type":"uint256"}],"name":"burn","outputs":[{"name":"success","type":"bool"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"name":"","type":"address"}],"name":"balanceOf","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"TransferAllowed","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"owner","outputs":[{"name":"","type":"address"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[],"name":"symbol","outputs":[{"name":"","type":"string"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[{"name":"_to","type":"address"},{"name":"_value","type":"uint256"}],"name":"transfer","outputs":[{"name":"success","type":"bool"}],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":true,"inputs":[{"name":"","type":"address"}],"name":"frozenAccount","outputs":[{"name":"","type":"bool"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":true,"inputs":[{"name":"","type":"address"},{"name":"","type":"address"}],"name":"allowance","outputs":[{"name":"","type":"uint256"}],"payable":false,"stateMutability":"view","type":"function"},{"constant":false,"inputs":[],"name":"disableTokenTransfer","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"name":"target","type":"address"},{"name":"freeze","type":"bool"}],"name":"freezeAccount","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"constant":false,"inputs":[{"name":"newOwner","type":"address"}],"name":"transferOwnership","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"},{"inputs":[{"name":"initialSupply","type":"uint256"},{"name":"tokenName","type":"string"},{"name":"tokenSymbol","type":"string"}],"payable":false,"stateMutability":"nonpayable","type":"constructor"},{"anonymous":false,"inputs":[{"indexed":false,"name":"target","type":"address"},{"indexed":false,"name":"frozen","type":"bool"}],"name":"FrozenFunds","type":"event"},{"anonymous":false,"inputs":[{"indexed":false,"name":"","type":"bool"}],"name":"TransferEnabled","type":"event"},{"anonymous":false,"inputs":[{"indexed":false,"name":"","type":"bool"}],"name":"TransferDisabled","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"from","type":"address"},{"indexed":true,"name":"to","type":"address"},{"indexed":false,"name":"value","type":"uint256"}],"name":"Transfer","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"from","type":"address"},{"indexed":false,"name":"value","type":"uint256"}],"name":"Burn","type":"event"}];

var myContractInstance = web3.eth.contract(abi).at(contractAddress);

var event = myContractInstance.Transfer({_from: myaddress}, {fromBlock:0, toBlock: 'latest'});

event.watch(function(error, result){
 if (!error)
   console.log(result);
});  

然後返回

Filter {
 requestManager: 
  RequestManager {
    provider: 
     HttpProvider {
       host: 'https://rinkeby.infura.io/MYINFURATOKEN',
       timeout: 0,
       user: undefined,
       password: undefined,
       headers: undefined },
    polls: {},
    timeout: null },
 options: 
  { topics: 
     [ '0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef',
       null,
       null ],
    from: undefined,
    to: undefined,
    address: '0x31a86307bfe81780a47fe98c192004ccdce8fcc0',
    fromBlock: '0x0',
    toBlock: 'latest' },
 implementation: 
  { newFilter: { [Function: send] request: [Function: bound ], call: [Function: newFilterCall] },
    uninstallFilter: { [Function: send] request: [Function: bound ], call: 'eth_uninstallFilter' },
    getLogs: { [Function: send] request: [Function: bound ], call: 'eth_getFilterLogs' },
    poll: { [Function: send] request: [Function: bound ], call: 'eth_getFilterChanges' } },
 filterId: null,
 callbacks: [ [Function] ],
 getLogsCallbacks: [],
 pollFilters: [],
 formatter: [Function: bound ] }

我很確定這不是令牌交易歷史……還是我錯過了一個步驟？

我怎麼從這裡走？

先感謝您。賈斯汀。

你想要的是我相信的*過去事件。*

我在這里和你做同樣的事情。這確實向你展示了代幣交易歷史，問題是，它不會向你展示特定地址的代幣交易歷史。
