如果是在合约外部判断，则可以使用web3.eth.getCode()，或者是对应的JSON-RPC方法eth_getcode。
getCode()用来获取参数地址所对应合约的代码，如果参数是一个外部账号地址，则返回"0x"；如果参数是合约，则返回对应的字节码，如下所示：

web3.eth.getCode("0xa5Acc472597C1e1651270da9081Cc5a0b38258E3")
"0x"

web3.eth.getCode("0xd5677cf67b5aa051bb40496e68ad359eb97cfbf8")

"0x600160008035811a818181146012578301005b601b6001356025565b8060005260206000f25b600060078202905091905056"

这样我们就可以通过getCode()的内容判断是哪一种地址了。
