在Azure中，我可以从C＃WebJob调用Python脚本吗？

Question

我想在C＃中创建一个WebJob。不幸的是，我需要使用Python 3脚本，因为目前我不需要使用C＃执行特定任务的合适库。

例如，请参阅此answer/example。

是否可以让我的WebJob调用Python脚本？我可以将Python3脚本放在blob容器中 - 然后我可以从C＃WebJob调用并执行它吗？

Answer 1

Sure, it's possible to call a Python 3 script via C# WebJob that follow the sample you linked. First of all, you need to install a Python 3 runtime as below.

1. Access the kudu tool via the url https://<your webapp name>.scm.azurewebsites.net, and follow the figure below to install a Python 3 runtime.
2. For example to install Python 3.5.2 x86, it will be installed in the path D:\home\Python35, then you just need to change the Python execute file path in the sample to try to run it.

Hope it helps.

Update: Install pip tool & other Python packages.

1. Access the url https://<your azure webapp name>.scm.azurewebsites.net/DebugConsole.

2. Commands as below.

   D:\home>cd Python35
   D:\home\Python35>curl https://bootstrap.pypa.io/get-pip.py --output get-pip.py
     % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                    Dload  Upload   Total   Spent    Left  Speed

   D:\home\Python35>python get-pip.py
   Requirement already up-to-date: pip in d:\home\python35\lib\site-packages
   Collecting wheel
     Downloading wheel-0.29.0-py2.py3-none-any.whl (66kB)
   Installing collected packages: wheel
   Successfully installed wheel-0.29.0
   

3. For example, install numpy package

   D:\home\Python35>python get-pip.py numpy
   Collecting numpy
     Downloading numpy-1.13.1-cp35-none-win32.whl (6.8MB)
   Installing collected packages: numpy
   Successfully installed numpy-1.13.1

不知道这是否是最佳方法，但这是我过去的做法：

• 创建一个python webjob（手动，触发）（see tutorial）

• 创建一个C＃webjob。

• 从C＃作业中触发Python作业：

  using (var client = new HttpClient())
  {
      var username = "jobusername";
      var password = "jobpassword";
      var byteArray = Encoding.ASCII.GetBytes($"{username}:{password}");
      client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));
      var response = await client.PostAsync("joburl", null);
  }
  

您可以在azure门户网站上的作业属性中找到作业凭据：
