Flask server not visible from my public ip address
提问by Keatinge
I'm trying to run a flask server on my desktop PC that is publicly available on the internet. I've done the following:
我正在尝试在我的台式电脑上运行一个可在互联网上公开获得的 Flask 服务器。我做了以下工作：
- Set up a static IP address: 192.168.1.11 (http://i.imgur.com/Z9GEBYV.png)
- Forwarded port 33 on my router to my static ip address (http://i.imgur.com/KGNQ2Qk.png)
- Setup flask to use my static ip and port: 33
- 设置静态 IP 地址：192.168.1.11 ( http://i.imgur.com/Z9GEBYV.png)
- 将路由器上的端口 33 转发到我的静态 IP 地址 ( http://i.imgur.com/KGNQ2Qk.png)
- 设置烧瓶以使用我的静态 ip 和端口：33
I'm using the following code as a test webserver
我使用以下代码作为测试网络服务器
from flask import Flask, request, redirect
app = Flask(__name__)
@app.route("/")
def hello_world():
return "Test 123 "
if __name__ == "__main__":
app.run(host="0.0.0.0", port="33")
When I open my browser to: http://192.168.1.11:33/the page displays properly, I see "Test 123"
当我打开浏览器到：http: //192.168.1.11: 33/页面正确显示时，我看到“Test 123”
My problem comes when trying to connect to my webserver from my public ip addressWhen I open my browser to http://xx.xxx.xxx.xx:30(my ip address) all I see is "this site can't be reached, xx.xxx.xxx.xx refused to connect"
试图从我的公网IP地址连接到我的网络服务器时，我的问题就来了。当我打开我的浏览器//xx.xxx.xxx.xx：HTTP 30（我的IP地址）所有我看到的是“这个网站不能已到达，xx.xxx.xxx.xx 拒绝连接”
I've looked up all the stack overflow answers, I've done the following:
我已经查找了所有堆栈溢出的答案，我已经完成了以下操作：
- Turned off windows firewall
- Changed host from "192.168.1.11" to "0.0.0.0"
- Tried a different port
- 关闭windows防火墙
- 将主机从“192.168.1.11”更改为“0.0.0.0”
- 尝试了不同的端口

My question is: What do I need to do to make my flask server visible from my public ip address?
我的问题是：我需要做什么才能让我的 Flask 服务器从我的公共 IP 地址可见？

Do you have DHCP activated on your router? If yes do you see your host as 192.168.1.11 in there?
您的路由器上是否启用了 DHCP？如果是，您是否在那里看到您的主机为 192.168.1.11？
You have to use '0.0.0.0' on host, that tells Flask to listen on all addresses.
Try specifying the port with quotes as app.run(host="0.0.0.0", port="33")
您必须在主机上使用“0.0.0.0”，它告诉 Flask 侦听所有地址。尝试用引号将端口指定为app.run(host="0.0.0.0", port="33")
回答by ganeshredcobra
change it to app.run(host= '0.0.0.0', port="33") to run on your machines IP address.
将其更改为 app.run(host='0.0.0.0', port="33") 以在您的机器 IP 地址上运行。
Documented on the Flask site under "Externally Visible Server" on the Quickstart page: http://flask.pocoo.org/docs/0.10/quickstart/#a-minimal-application

You must give the public ip address/LAN ip address as an argument to app.run method. When you don't provide host argument, it works fine with http://localhost:8888/and http://127.0.0.1:888/, but not to access outside the system where you are running the REST services
您必须将公共 ip 地址/局域网 ip 地址作为 app.run 方法的参数。当您不提供主机参数时，它适用于http://localhost:8888/和http://127.0.0.1:888/，但不能在您运行 REST 服务的系统外部访问
Following is the example. app.run(host="192.168.0.29",debug=True, port=8888)
以下是示例。app.run(host="192.168.0.29",debug=True, port=8888)

Every webservice should be run from different port address.Single service is running from a single port.
每个 webservice 应该从不同的端口地址运行。单个服务从单个端口运行。
回答by Pankus
You must try and use the same ip of the development server. Thus, for instance, if the dev server is running on a PC with the address 192.168.1.11and port 33, other clients must point at the same address: 192.168.1.11:33.
As far as my small experience, it works with the debugger disabled, but I did not check if this is an essential prerequisite.
您必须尝试使用与开发服务器相同的 IP。因此，例如，如果开发服务器在具有地址192.168.1.11和端口的 PC 上运行33，则其他客户端必须指向相同的地址：192.168.1.11:33。就我的小经验而言，它可以在禁用调试器的情况下工作，但我没有检查这是否是必不可少的先决条件。
good luck
祝你好运
