getAdaptersInfo 与 firefox 附加组件
getAdaptersInfo with firefox add-on
我想使用 firefox 插件获取一些独特的 machine 信息。
用这段代码我可以得到名字：
var dns = Cu.components.classes["@mozilla.org/network/dns-service;1"]
.getService(Cu.components.interfaces.nsIDNSService);
var myName = dns.myHostName;
现在我需要 NIC 信息（如 mac 地址、适配器名称）。我尝试使用 getAdaptersInfo 函数，但这只适用于 Windows，我需要一些跨平台的解决方案。
有人有想法吗？
这是我的 getAdaptersInfo 代码：
function getMacAddress(){
const MAX_ADAPTER_NAME_LENGTH = 256;
const MAX_ADAPTER_DESCRIPTION_LENGTH = 128;
const ERROR_BUFFER_OVERFLOW = 111;
const NO_ERROR = 0;
var IP_ADDRESS_STRING = ctypes.StructType('IP_ADDRESS_STRING',[
{'String': ctypes.char}
]);
var IP_ADDR_STRING = ctypes.StructType('IP_ADDR_STRING');
IP_ADDR_STRING.define([
{'Next': IP_ADDR_STRING.ptr},
{'IpAddress': IP_ADDRESS_STRING},
{'IpMask': IP_ADDRESS_STRING},
{'Context': ctypes.long}
]);
var IP_ADAPTER_INFO = ctypes.StructType('IP_ADAPTER_INFO');
const DWORD = ctypes.uint32_t;
IP_ADAPTER_INFO.define([
{'Next': IP_ADAPTER_INFO.ptr},
{'ComboIndex': DWORD},
{'AdapterName': ctypes.char},
{'Description': ctypes.char},
{'AddressLength': ctypes.int32_t},
{'Address': ctypes.uint8_t.array(10).ptr},
{'Index': DWORD},

{'DhcpEnabled': ctypes.uintptr_t},

{'HaveWins': ctypes.int32_t},
{'PrimaryWinsServer': IP_ADDR_STRING},
{'SecondaryWinsServer':IP_ADDR_STRING},
{'LeaseObtained': ctypes.uintptr_t},
{'LeaseExpires': ctypes.uintptr_t}
]);
const nomes = [ctypes.libraryName('IPHLPAPI')];
const lib = loadLibrary(nomes);
try{
if(!lib)
return null
console.log("Biblioteca aberta!");
/*DWORD GetAdaptersInfo(
_Out_ PIP_ADAPTER_INFO pAdapterInfo,
_Inout_ PULONG pOutBufLen
);*/
var getAdaptersInfo = lib.declare(
"GetAdaptersInfo",
ctypes.default_abi,
DWORD,
IP_ADAPTER_INFO.ptr,
ctypes.long.ptr);
let buf = (IP_ADAPTER_INFO)();
let pbuf = buf.address();
let ret = ctypes.long(2000);
let pret = ret.address();
let sts = getAdaptersInfo(pbuf,pret);
if(sts == ERROR_BUFFER_OVERFLOW){ //o tamanho do buffer enviado não foi o suficiente.
buf = null;
//agora mando novamente usando o que a lib me retornou.
sts = getAdaptersInfo(pbuf,pret);
}

throw Error("Erro buscando configuracoes do adaptador.");
}
}catch(ex){
console.log("Erro na biblioteca", ex, ex.message);
}finally{
lib.close();
}
}
但是当我 运行 cfx 运行 时 firefox 崩溃了。

好的，现在可以了 :) 问题是我告诉函数通过将其定义为 IP_ADAPTER_INFO.ptr.array() 来接受结构列表，然后我创建了一个像这样的结构数组 let pbuf = IP_ADAPTER_INFO.ptr.array(1)() 但是这会崩溃，当我们增加到 2 或更大的大小时，它崩溃得更快。所以我更改为在函数 IP_ADAPTER_INFO.ptr 中像这样声明它，然后我创建了一个结构数组，像这样 let pbuv = IP_ADAPTER_INFO.array(?) 其中 ? 可以是任何数字并且它工作正常:)

下面的旧东西-离开这里所以我可以从中学习，因为我第一次尝试通过将其定义为 IP_ADAPTER_LIST.ptr.array() 来告诉函数接受数组，但我不得不将其更改为 IP_ADAPTER_LIST.ptr如上所示
哇，老兄，我正在看更多，看起来它需要一个 IP_ADAPTER_INFO 数组，这样做不会在 Win7
上崩溃
不过我有一个问题，因为 ret 回来说所需的大小是 2560。但是我们的 IP_ADAPTER_INFO 结构的大小是 132。所以 2560/132 = 19.333 所以我们的结构出了点问题，我们必须弄清楚。 没关系，我解决了我曾尝试做的问题 ctypes.char.array(4*4).ptr 而不仅仅是 ctypes.char.array(4*4)
所以这是我发现我们需要传递一个 IP_ADAPTER_INFO 数组的地方：https://github.com/manimaul/Matrix-Mariner-GPS/blob/8989621dfda0e291820a37096d582cc1f355e346/src/getIPwin.py#L45
这是我的作品，所以现在的问题是它在第二次获取后崩溃了。我们需要解决这个问题。
编辑：
好的，伙计，这绝对是在正确的轨道上，它现在在所有系统上的第二次获取时崩溃，win7 和 win81（我没有尝试 xp，但我相信它会），我们必须弄清楚它到底为什么会崩溃。如果你注释掉第二个 sts = getAdapters... 它不会崩溃，我们必须解决这个问题 哈哈

下面的旧东西-离开这里所以我可以从中学习，因为我第一次尝试通过将其定义为 IP_ADAPTER_LIST.ptr.array() 来告诉函数接受数组，但我不得不将其更改为 IP_ADAPTER_LIST.ptr如上所示
哇，老兄，我正在看更多，看起来它需要一个 IP_ADAPTER_INFO 数组，这样做不会在 Win7
不过我有一个问题，因为 没关系，我解决了我曾尝试做的问题 ret 回来说所需的大小是 2560。但是我们的 IP_ADAPTER_INFO 结构的大小是 132。所以 2560/132 = 19.333 所以我们的结构出了点问题，我们必须弄清楚。ctypes.char.array(4*4).ptr 而不仅仅是 ctypes.char.array(4*4)
所以这是我发现我们需要传递一个 IP_ADAPTER_INFO 数组的地方：https://github.com/manimaul/Matrix-Mariner-GPS/blob/8989621dfda0e291820a37096d582cc1f355e346/src/getIPwin.py#L45
这是我的作品，所以现在的问题是它在第二次获取后崩溃了。我们需要解决这个问题。
编辑：
好的，伙计，这绝对是在正确的轨道上，它现在在所有系统上的第二次获取时崩溃，win7 和 win81（我没有尝试 xp，但我相信它会），我们必须弄清楚它到底为什么会崩溃。如果你注释掉第二个 sts = getAdapters... 它不会崩溃，我们必须解决这个问题 哈哈
