计为 1 个 Request。 计费规则见 Request Counting。

返回指定地址的代码内容。可用于判断一个地址是否为智能合约地址。

参数

DATA（20 字节）— 目标地址。
QUANTITY|TAG — 区块号，或 "latest"、"earliest"、"pending"。

DATA — 该地址上的代码。EOA（非合约地址）返回 0x。

请求


{
  "jsonrpc": "2.0",
  "method": "eth_getCode",
  "params": ["0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", "latest"],
  "id": 1
}

响应


{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0x6080604052..."
}

请把示例地址换成 BSC 上的合约地址。

若返回值为 "0x"，表示该地址是 EOA（外部拥有账户），不是合约。
