Firefox addon 带有firefox插件的GetAdapterInfo

我想使用firefox插件获得一些独特的机器信息

使用此代码，我可以获得以下名称：

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）。我试图使用

getAdapterInfo

函数，但这只适用于Windows，我需要一些跨平台的解决方案

有人有主意吗

这是我的GetAdapterInfo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},
        {'Type': ctypes.uintptr_t},
        {'DhcpEnabled': ctypes.uintptr_t},
        {'CurrentIpAddress': IP_ADDR_STRING.ptr},
        {'IpAddressList': IP_ADDR_STRING},
        {'GatewayList' : IP_ADDR_STRING},
        {'DhcpServer': IP_ADDR_STRING},
        {'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);
        }

        if(sts != NO_ERROR){ //aqui ocorreu um erro que não conseguiremos resolver ainda.
            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 run时，firefox崩溃。

忽略此解决方案这是非常错误的-请参阅我的第二个解决方案，它正在进行中。 您的代码正常工作，只需访问

pbuf

的

.contents

，将下面的代码复制粘贴到scratchpad，将环境设置为browser并点击run。请参见此处，了解如何从草稿行启用浏览器环境：

好了，现在可以了：）问题是我告诉函数接受结构列表，将其定义为

IP\u ADAPTER\u INFO.ptr.array（）

然后我创建了一个结构数组，就像这样

让pbuf=IP\u ADAPTER\u INFO.ptr.array（1）（

但是这会崩溃，当我们增加到2个或更多的尺寸时，崩溃速度更快。所以我修改了，在函数

IP\u ADAPTER\u INFO.ptr

中这样声明它，然后我创建了一个类似这样的结构数组

let pbuv=IP\u ADAPTER\u INFO.array（？）

其中

？

可以是任何数字，并且工作正常：）

当我有机会的时候，我会进入，现在正忙于我自己的一个项目。不过，看看这个主题：谢谢。这个主题的解决方案很酷，但我需要一些更独家的信息，比如mac地址。我也会尝试不同的方法，比如生成一个唯一的id并保存到某个地方（可能是简单的存储）嗨，谢谢！你测试过wich OS吗？运行此代码时，使用Windows 8 firefox会崩溃。你知道为什么吗？我用的是Windows8.1。我将在Win7和WinXP上进行测试，并向您报告，您是否复制粘贴了我放在这里的内容？哦，哎哟，我也在Win81上崩溃了。让我修改代码。好的，在@Sabbathman复制粘贴，现在它可以工作了。在我没有回顾WinAPI之前，你的一些类型是错误的。在Win81和WinXP上测试。我的Win7机器出现网络问题，因此此代码不断尝试访问一些不可用的信息，因此可能会崩溃，但这是意料之中的。因此，如果有网络问题，它会崩溃，如果你运行这个，所以你必须找出这些网络问题是什么，并在运行这个代码之前检测它们。事实上，我不知道为什么它会在我的Win7上崩溃，这里有一些评论：当你明白了，请分享。但是代码应该是好的。它适用于XP和8.1是的，很奇怪。。。我有，我很快会测试并在这里报告。请看注释掉的那一行

//在这里崩溃

我需要帮助使那一行不崩溃。不要使用上面的代码，使用这个代码，这是正确的方法，即使它现在崩溃了。它只有在我第二次运行时才会崩溃。我想我们需要清除DLL中的某些内容。我会设法弄明白的。我们可以指定主MAC地址吗？好的@Sabbathman solution找到并发布了，我留下了旧的东西，这样我们可以看到差异并从中学习：）谢谢@Noitidart，我当然从这个问题中学到了很多。对于abi，我使用了ctypes.winapi_abi，因为我的ff是32位的，但对于64位，你必须使用ctypes.default\u abi，如下所示：
