blockchain - 获取 Pancake Swap 的 Old Pair PairCreated 事件

Question

我正在尝试阅读煎饼工厂地址的过去事件。但我没有得到回应。

        var contractInstance = new web3.eth.Contract(abi, "0xcA143Ce32Fe78f1f7019d7d551a6402fC5350c73");

    contractInstance.getPastEvents('PairCreated', {
    filter: {address: "0xa5dd1b661fc1ea194db427cf12aa3cd715312a84"},  
    fromBlock: 0,
    toBlock: 'latest'
    }, (error, events) => { 
    // Should return event
      var obj=JSON.parse(JSON.stringify(events));
    }
    else {
      console.log(error)
    }})

也许没有来自 0xa5dd1b661fc1ea194db427cf12aa3cd715312a84 的 CreatePair 事件？试试这个没有过滤器的表格：

var contractInstance = new web3.eth.Contract(abi,"0xcA143Ce32Fe78f1f7019d7d551a6402fC5350c73");

contractInstance.getPastEvents('PairCreated', {
fromBlock: 0,
toBlock: 'latest'
}, (error, events) => { 
// Should return event
  var obj=JSON.parse(JSON.stringify(events));
}
else {
  console.log(error)
}})
