将Microsoft Azure Function App 2.0预览版绑定到0.0.0.0 [英] Bind Microsoft Azure Function App 2.0 preview to 0.0.0.0

问题描述

我有一个用C#编写的Microsoft Azure Function App 2.0预览版，该预览版绑定到

如何使它绑定到0.0.0.0而不是localhost，以便可以从本地网络上的另一台计算机访问它?

查看这些 Microsoft文档我可以在 local.settings.json 文件中看到如何指定端口主持人": {"LocalHttpPort":7071，"CORS":"*"}

但不使用哪个网络接口.

来自Rails背景，我可以这样做: rails s -b 0.0.0.0

如何在.net/Azure函数世界中做到这一点?

解决方案

UPDATE—

您不再需要此方法，因为默认情况下，函数主机现在在 0.0.0.0:7071 上侦听:

 <代码> $ func -v2.0.1-beta.33$ func |grep运行时函数运行时版本:2.0.11933.0$ func主机启动|grep -i听收听:http://0.0.0.0:7071

现在已弃用—

如果您使用的是Windows，

  C:\> netsh接口portproxy add v4tov4 listenport = 8081 ^listenaddress = 0.0.0.0 connectport = 7071 connectaddress = 127.0.0.1C:\> netsh界面portproxy全部显示在ipv4上收听:连接到ipv4:地址端口地址端口--------------- ---------- --------------- ----------0.0.0.0 8081 127.0.0.1 7071C:\> netstat -an |的findstr 8081TCP 0.0.0.0:8081 0.0.0.0:0侦听C:\> netstat -an |的findstr 7071TCP 127.0.0.1:7071 0.0.0.0:0侦听 

要测试:

  C:\> curl.exe http://192.168.111.4:8081/api/HttpTrigger -iHTTP/1.1 200 OK日期:2018年3月28日，星期三，格林尼治标准时间内容类型:application/json;字符集= utf-8服务器:红est传输编码:分块哦，海." 

要摆脱portproxy:

  C:\> netsh接口portproxy删除v4tov4 listenport = 8081 listenaddress = 0.0.0.0 

在Linux上，iptables可以通过它运行；在Mac上，iptables可以通过它运行……我不知道，nginx是您的出路吗?好的，似乎有一个 pfctl 工具，可能是继承的来自BSD?

尽管Kestrel是服务器，但是设置环境变量 ASPNETCORE_URLS ="http://*:7071" 无效.函数主机可能会在代码中以 localhost 引导，这可能暗示您不应该裸露它，而应该将代理反向添加到其中.

I have a Microsoft Azure Function App 2.0 preview written in C# which binds to http://localhost:7071.

How do I get it to bind to 0.0.0.0 instead of localhost so I can access it from another machine on my local network?

Looking at these Microsoft Docs I can see how to specify the port in the local.settings.json file "Host": { "LocalHttpPort": 7071, "CORS": "*" }

But not which Network Interface to use.

Coming from a Rails background I would do this with: rails s -b 0.0.0.0

How do I do this in the .net / Azure Function world?

解决方案

UPDATE —

You don't need this sorcery anymore as the functions host now listens on 0.0.0.0:7071 by default:

$ func -v
2.0.1-beta.33

$ func | grep Runtime
Function Runtime Version: 2.0.11933.0

$ func host start | grep -i listen
Listening on: http://0.0.0.0:7071

NOW DEPRECATED —

If you're on Windows,

C:\>netsh interface portproxy add v4tov4 listenport=8081 ^
        listenaddress=0.0.0.0 connectport=7071 connectaddress=127.0.0.1


C:\>netsh interface portproxy show all

Listen on ipv4:             Connect to ipv4:
Address         Port        Address         Port
--------------- ----------  --------------- ----------
0.0.0.0         8081        127.0.0.1       7071


C:\>netstat -an  | findstr 8081
  TCP    0.0.0.0:8081           0.0.0.0:0              LISTENING

C:\>netstat -an  | findstr 7071
  TCP    127.0.0.1:7071         0.0.0.0:0              LISTENING

To test it out:

C:\>curl.exe http://192.168.111.4:8081/api/HttpTrigger -i
HTTP/1.1 200 OK
Date: Wed, 28 Mar 2018 18:25:31 GMT
Content-Type: application/json; charset=utf-8
Server: Kestrel
Transfer-Encoding: chunked

"Oh hai."

To get rid of portproxy:

C:\>netsh interface portproxy delete v4tov4 listenport=8081 listenaddress=0.0.0.0

On Linux, iptables your way through it, on a Mac... i don't know, nginx your way out? Okay, there seems to be a pfctl tool, probably inherited from BSDs?

Although Kestrel is the server, setting the environment variable ASPNETCORE_URLS="http://*:7071" has no effect. The function host is probably bootstrapped with localhost in code, which may be a hint that you're not supposed to expose it naked and you should reverse proxy into it.
