我可以在不使用外部服务的情况下在Chrome应用程序中获得我的IP地址吗？ [英] Can I get my IP address in a chrome app without using an external service?

问题描述

我正在构建一个 Chrome应用并创建了一个 UDP套接字通过。

<有没有办法在不使用外部服务的情况下检索自己的 IP地址？
我的意思是自己的IP地址：客户端和服务器在同一个网络上。 chrome应用需要使用自己的本地IP地址应答 UDP广播。

实际上，这个用例实际上是一个 Chrome套接字API 。但不幸的是，我只收到下面的回调对象： Object {paused：false，persistent：false，socketId：17} ，它忽略了 localAddress 属性。它是根据 SocketInfo 对象中的（可选）属性/ sockets_udp＃type-SocketInforel =nofollow>文档。这实际上是我正在运行的代码：

  chrome.sockets.udp.create（{}，function（socketInfo）{ 
 chrome.sockets.udp.getInfo（socketInfo.socketId，function（detailedInfo）{
 ipAddress = detailedInfo.localAddress; 
 console.debug（detailedInfo）; // containts no`localAddress` 
}）; 
}）; 
  

我也不认为我缺少任何 manifest-permissions ，因为 API文档。这是我使用的：

 sockets：{
udp：{
send ：*，
bind：*
} 
} 
  

当我使用 Python 时，我可以如下实现该目标：

  import socket 
 ip_address = socket.gethostbyname（socket.gethostname（））
  

很好！

解决方案

事实证明我一直在使用错误的API。对于我的用例，我需要使用 chrome.system.network.getNetworkInterfaces 。

这将返回一个包含 IP地址的所有接口的数组。

是我的示例代码：

  chrome.system.network.getNetworkInterfaces（function（interfaces）{
 console.log接口）; 
}）; 
  

清单权限：

 permissions：[
system.network
]，
  

考虑到评论，一个完美的解决方案不容易提供，因为必须找到正确的UDP端口接口。

在这一点上，完美匹配接口的唯一方法是使用 bind 所有接口的所有地址 getNetworkInterfaces 。然后您就可以确切知道使用哪个接口接听电话，您可以使用正确的IP地址进行响应。

I am building a chrome app and created a UDP socket via the chrome socket api.

Is there a way to retrieve your own IP address without using an external service? What I mean by "own IP address": Both client and server are on the same network. The chrome app needs to answer to a UDP broadcast with it's own local IP address.

There is actually a chrome socket API for exactly that use-case. But unfortunately I only receive the following callback object: Object {paused: false, persistent: false, socketId: 17}, which misses the localAddress attribute. It is an (optional) attribute in the SocketInfo object according to the documentation. This is in essence the code I am running:

chrome.sockets.udp.create({}, function(socketInfo){
    chrome.sockets.udp.getInfo(socketInfo.socketId, function (detailedInfo){
        ipAddress = detailedInfo.localAddress;
        console.debug(detailedInfo); // containts no `localAddress`
    });
});

I also do not think that I am missing any manifest-permissions as there are no special permissions described in the API documentation. This is what I use:

"sockets": {
  "udp": {
    "send": "*",
    "bind": "*"
  }
}

When I use Python I can achieve that goal as follows:

import socket
ip_address = socket.gethostbyname(socket.gethostname())

Any help would be great!

解决方案

turns out that I have been using the wrong API. For my use case I needed to use chrome.system.network.getNetworkInterfaces.

This will return an array of all interfaces with their IP address.

This is my sample code:

chrome.system.network.getNetworkInterfaces(function(interfaces){
    console.log(interfaces);
});

manifest-permissions:

"permissions": [
  "system.network"
],

Considering the comments a perfect solution is not easy to provide, as one has to find the correct interface to the UDP-port.

At this point the only way to perfectly match the interface one has to bind all addresses for all interfaces given by getNetworkInterfaces. Then you know exactly which interface was used to receive the call and you can respond with the correct IP address.
