azure-functions - Azure Function (REST API for Http Trigger & using Timer Trigger with Azure Data Factory)

Question

I am trying to develop an Azure Function and came across a question regards to the requirement for using HTTP Trigger.

I am trying to pull data using a third party's SDK, and it is XML-based web services (XML API), not REST API, so it appears that I cannot use HTTP Trigger.

1) My understanding is, in order to use HTTP Trigger, I need to have REST API, correct? How about XML API?

I am trying to go with Timer Trigger and use Azure Data Factory to pull data.

2) If I use Timer Trigger and Azure Data Factory (ADF), where does data get stored in between?

Is data stored in the storage account (Table or Blob) that I configured when I created Function App, and then when I execute ADF, data would be pulled from there?

And if so, how does data in the storage account gets truncated (for next run) after it is used?

3) I am trying to locate where the logic of pulling data should go within the Function CS file.

I guess I have to call a method from other cs file (ListVendors.cs) inside the Function app solution to list vendors' data, correct?

And the Main class is in another cs (Program.cs) file.

Do I call/put the class name (& method) inside the Function class inside Run method (as shown below)?

Function class (TimerTrigger_1109_1)

ListVendors class

Main method (Program.cs)

I am trying to understand how Function app gets called vs. how Main method is called within Function application.

4) When I run the solution, how does solution know which file to run (Function file or Main method within the solution)? Since this is Function solution, I am not sure how execution of solution works.

Thanks.

那么，如果我使用 Timer Trigger 并且有一个逻辑来提取数据列表，我该如何将数据移动到 ADF？

据我所知，ADF 不能直接使用 Timer trigger function.

但您可以先在 Azure 数据工厂中创建 计划触发器：

然后新建一个 Http Trigger Function，把原来写在里面的逻辑写 Time Trigger Function 进去 Time Trigger Function。然后使用 ADF 中的 Http 触发功能。

关于如何在 ADF 中使用 azure 功能，可以参考这篇 博客。
