过滤具有多个事务的 bscscan 对象以分离为两个匹配 key:values 的对象

Question

Using BSCScan's Accounts API , I am returning a list of transactions between a Contract address and a User address.

The response contains transaction details that are transfers from either:

• A) The contract to the user address (from buys)
• B) The user address to the contract (from sells)

In the BSCScan response, we can see information such as the tx hash / blockNumber / value and who it was from to etc. What I'm looking for is to sum all the value: entries separately for A and B where

• A) the from: key value is equal to the contract address and the to key value matches the user address
• B) the from: key value is equal to the user address and the to key value matches the contract address

My BSCScan fetch call and function is

useEffect(() => {
    fetch("https://api.bscscan.com/api?module=account&action=tokentx&contractaddress=0x9cdadB8982f772B64D852577CD85672D87b27974&address=0x541b79b200B40D37F91663e40Ca0B05512d0EB05&page=1&offset=5&startblock=0&endblock=999999999&sort=asc&apikey=xxxxxxxxxxxxxx")
      .then(resp => resp.json())
      .then(resp => {
        console.log(resp); 
        // console.log(resp.result); 
        // console.log(resp.result[0]); 
        // console.log(resp.result[0].from); 
        const data = resp.result
        let from = ['0x9cdadB8982f772B64D852577CD85672D87b27974'];   //im trying to filter out only the results with FROM: this address

var result2 = data.filter(function(e) {
  return from.indexOf(e.from)
})

console.log(result2)
      
        
      })
  }, []);

Here's the object I have, note there's five transactions here but in reality there would be many more to iterate through.

Answer 1

Resolved by using both Object.keys and filter as follows

useEffect(() => {
    fetch("https://api.bscscan.com/api?module=account&action=tokentx&contractaddress=0x9cdadB8982f772B64D852577CD85672D87b27974&address=" + accountData?.address + "&page=1&offset=5&startblock=0&endblock=999999999&sort=asc&apikey=XXXXXXX")
      .then(resp => resp.json())
      .then(resp => {
        //ALLTHE BUY TRANSACTIONS 
        var data = resp.result
        var result = Object.keys(data).map(function(key) {
          return data[key];
        });
       
        var filtered = result.filter(row => { return row.from === address.toLowerCase() });
        var filteredvalues = filtered.filter(row => { return row.value; });

        var buys = []

        const allbuys = filtered
        .filter(row => { return row.value ; })
        .map(({value}) => value);


        buys.push(allbuys)
        console.log("ALL BUY VALUES ARE:")
        console.log(buys);

      })
  }, []);
