HTTP Binding in PowerShell Azure Functions

Check the code here at commit dcc9e1d Output Similar to the request, your script should write the response to a file, which in turn will be read by the Azure Functions runtime, and then will pass it to the HTTP output binding to send it on your behalf. Conclusion PowerShell probably is the language that got the least love from the Azure Functions team, but this does not mean that you throw your scripts away, hopefully with the tips in this post you will find a way to use them again.

If the Function is executing because of a Triggered bindings such as HTTPthe rest of the input bindings are skipped.

This can be found here at commit 3b3e8cb. Use the WriteAllText command instead. Formatters Great, so far we managed to change the body, the headers including the content-typeand the status of the response.

So for the example above of function. If the recipient is not ready for this it might cause a problem. Take the following as an example: More Control If we want more control over the response then you have to write JSON object to the file, this JSON object will hold all the information on how the response should look like: The parsing can be found here at commit 3b3e8cb.

I try to link back to the source code wherever I can, the problem is the link does not include the commit ID, so next to the link I put the commit ID at which the file was in that state.

To read the body of the request you just read it as you read any file PowerShell, and then you parse it according to the content; so if the body of the request is JSON you read the file and parse it to JSON like the following: This is when I decided to look in the source code rather than the documentation.

The JSON object should contain the properties: Have you noticed the characters I surrounded with the red box? But this is also not enough; depending on the content-type header, the Azure Functions runtime will find the right MediaFormatter for the content and format the response body with the right format.

There are several types of MediaFormatters in the System. This happens here at dcc9e1d. All of this happen before the execution of the Function, so once the Function is invoked these variables are already available for consumption. Dropbox, for example, provides a way to watch the changes to a file through their API by registering a webhook, and the way Dropbox verifies the webhook is by making a request to the endpoint with a specific querystring, then it expects the webhook to respond by echoing the querystring back.

So, naively, I followed the basic template as an example:This post explains how HTTP binding works with Powershell Azure Functions: setting HTTP headers, content-type, response status code, and more. If you don't want the controller to decide the return object type, you should set your method return type as ultimedescente.comsponseMessage and use the below code to return the XML.

public HttpResponseMessage Authenticate() { //process the request.
