我正在尝试从Azure webjob运行python脚本.这是我在

I'm trying to run python script from Azure webjob. This is what I've done following this link

1. 通过URL https://<webapp name>.scm.azurewebsites.net访问kudu工具，并通过站点扩展"标签
安装Python 364x86
2. 已确认Python 364x86已安装在以下路径中:D:\home\python364x86
3. 在D:\home\python364x86
中添加了我的脚本trading.py
4. 使用此行代码D:\home\python364x86\python.exe trading.py
创建的run.bat文件
5. 包含在webjob zip文件中的run.bat和trading.py
6. 已部署，但出现错误

1. Access the kudu tool via the url https://<webapp name>.scm.azurewebsites.net and installed Python 364x86 via Site Extensions tab
2. Confirmed Python 364x86 is installed in the following path: D:\home\python364x86
3. Added my script trading.py in D:\home\python364x86
4. Created run.bat file with this line of code D:\home\python364x86\python.exe trading.py
5. Included run.bat and trading.py in the webjob zip file
6. Deployed, but getting error

                results = process.StandardOutput.ReadToEnd();               
            }

            Console.WriteLine("Errors:");
            Console.WriteLine(errors);

            Console.WriteLine("Results:");
            Console.WriteLine(results);
        }

以上代码执行python脚本. 它在本地工作，但是一旦将其部署到生产环境中，它就会失败.尝试了很多次，花费了大量时间，但仍不确定为什么刺棒不起作用.感谢您的帮助.

Above code executes python script. It works locally, but once I deploy it to production it fails. Tried so many times, spent plethora of hours, but still unsure why prod doesn't work. Help is appreciated.

trading.py

trading.py

import telegram

my_token = 'mytoken'
bot = telegram.Bot(token = my_token)

chat_id = 'mychatid'
message = 'Hello
bot.sendMessage(chat_id=chat_id, text=message)

推荐答案

我试图通过WebJob中的Python来实现您的需求，并成功使之工作.

I tried to realize your needs with Python in WebJob and successfully make it works.

这是我的步骤和示例代码.我的本地环境是Windows 10上的Python 3.7.

Here is my steps and sample code. My local environment is Python 3.7 on Windows 10.

1. 创建Python虚拟环境并通过以下命令安装python-telegram-bot软件包.

$ mkdir telegram-webjob
$ virtualenv telegram-webjob
$ cd telegram-webjob
$ Scripts\active
$ pip install python-telegram-bot
$ pip freeze

我将您的代码更改为示例代码，然后在本地运行，如下所示.

I changed your code as my sample code, then run it works fine on local, as below.

import telegram
from datetime import datetime as dt

my_token = '<my token>'
bot = telegram.Bot(token = my_token)

chat_id = '<chat id>'
message = f"Hello at {dt.now()}"
bot.sendMessage(chat_id=chat_id, text=message)

我创建了一个名为webjob的新目录，并将我的trading.py文件和所有目录及其文件复制到其中，如下所示.

I created a new directoy named webjob and copy my trading.py file and all directories with their files into it, as below.

编写名为run.bat的启动bat脚本，代码如下.

Write the startup bat script named run.bat, the code as below.

D:\home\python364x86\python.exe trading.py

D:\home\python364x86\python.exe路径是python364x86网站扩展安装路径，如下图.

The D:\home\python364x86\python.exe path is the python364x86 site extension installed path as the figure below.

然后，我将webjob目录中的所有目录和文件打包为zip文件，如下所示.

Then, I packaged the all directories and files in the webjob directory as a zip file, as below.

我将它作为webjob上传到Azure WebApp，如下图所示，并启动它.

I uploaded it to Azure WebApp as a webjob, as the figure below, and start it.

最后，它对我来说很好用，我可以看到电报客户端中显示的消息间隔为10秒.

Finally, it works fine for me and I can see the message interval 10 sec displayed in my telegram client.
