Infura getLogs 返回空結果

我正在Infura上使用 PHP 編寫一個基於加密的系統，現在我正在編寫一個腳本來檢索特定地址的日誌。這是我的程式碼：

$ch = curl_init($my_server_url);

$data = array(
   'jsonrpc' => '2.0',
   'id' => 1,
   'method' => 'eth_getLogs',
   'params' => array(array('address'=>'0x7d8f5F4ACa6Ca7Eb857A9F36d46b0aA715a88849'))
);
$payload = json_encode($data);
curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);
echo $result;

但是在執行結束時什麼都沒有返回，而我在這個地址上有 2 筆交易。我只收到這個最終結果：

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": []
}

你能告訴我我的錯誤在哪裡嗎？

事件是由合約發出的，但您使用的地址0x7d8f5F4ACa6Ca7Eb857A9F36d46b0aA715a88849不是合約。但該地址有三個相關的 Erc20 Token 交易。

假設您希望查看相關合約0xdac17f958d2ee523a2206206994597c13d831ec7中的事件。

您必須使用您的特定帳戶過濾主題，如下例所示：

   <?php 
   $my_server_url = "https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_KEY";
   $ch = curl_init($my_server_url);
   $data = array(
       'jsonrpc' => '2.0',
       'id' => 1,
       'method' => 'eth_getLogs',
       'params' => array(array(
           "fromBlock" => "0x0",
           "toBlock"   => "latest",
           "topics" => array(null, null, "0x0000000000000000000000007d8f5F4ACa6Ca7Eb857A9F36d46b0aA715a88849"),
           "address"   => "0xdAC17F958D2ee523a2206206994597C13D831ec7"
       ))
   );
   $payload = json_encode($data);
   curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);
   curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
   $result = curl_exec($ch);
   curl_close($ch);
   echo $result;

結果將是：

   "id": 1,
