If you're looking for help with C. NET, Azure, Architecture, or would simply value an independent opinion then please get in touch here or over on Twitter. When I originally posted this piece the library I was using and developing was in an early stage of development. Serverless might not form your whole solution but for the right problem the technology and patterns can be transformational shifting the focus ever further away from managing infrastructure and a platform towards focusing on your application logic.

However… its a bit awkward. Azure Functions are more abstract than something like ASP. For example the out the box example for a function that responds to a HTTP request looks like this:. I think the boilerplate and cruft that goes with a typical ASP. NET Core and Azure Functions but they have to ship something that allows for as many user scenarios as possible — whereas simplifying something is generally about making decisions and assumptions on behalf of users and removing things.

I had some very specific technical objectives:. Probably the easiest way to illustrate how this works is by way of an example — so fire up Visual Studio and follow the steps below.

Firstly create a new Azure Function project in Visual Studio. After your project is created you should see an empty Azure Functions project.

Getting Started with Azure API Management REST API

The next step is to add the required NuGet packages — using the Package Manager Console run the following commands:. The first package adds the references we need for the commanding framework and Function specific components while the second adds an MSBuild build target that will be run as part of the build process to generate an assembly containing our Functions and the corresponding JSON for them. Next create a folder in the solution called Queries and into that add a class called GetBlogPostQuery:.

To do this we need to add a class into the project that implements the IFunctionAppConfiguration interface. This class is used in two ways: firstly the FunctionMonkey. Compiler package will look for this in order to compile the assembly containing our function triggers and the associated JSON, secondly it will be invoked at runtime to provide an operating environment that supplies implementations for our cross cutting concerns.

The interface requires us to implement the Build method and this is supplied a IFunctionHostBuilder and its this we use to define both our Azure Functions and a runtime environment. In this simple case its very simple.

Firstly in the Setup method we use the supplied commandRegistry an ICommandRegistry interface — for more details on my commanding framework please see the documentation here to register our command handlers our GetBlogPostQueryHandler class via a discovery approach supplying ServerlessBlogConfiguration as a reference type for the assembly to search.

The serviceCollection parameter is an IServiceCollection interface from Microsofts IoC extensions package that we can use to register any further dependencies.

Secondly we define our Azure Functions based on commands. The function naming uses a convention based approach which will give each function the same name as the command but remove a postfix of Command or Query — hence GetBlogPost.Connect your favourite version control system to your API and automatically deploy commits, which makes code changes easier than ever.

It will be used to perform the following operations. In Configure, your new project provides the below information.

Here, click "Create". Now when we create a new Task item, we could allow the caller of our API to just pass in an entire serialized instance of this Task class, but actually I don't want the caller of my API to be able to choose the Id or override the created date, and it's actually a good practice from a security perspective to only allow the caller of your APIs to specify the properties that you explicitly allow.

So, what I've done is I've made a very simple TodoCreateModel class that defines the one and only property that you're allowed to set when you're creating a new task, and that's the description. Everything else will get its default values. I've defined a custom entity called TaskUpdateModel that contains only the fields that I want users to be allowed to change.

And so, we can see the definition of the TaskUpdateModel class here, and it's simply going to allow callers to update the TaskDescription and change the IsCompleted flag. Although the tooling likes to create a new class for each function, it's perfectly possible for you to organize your functions how you want, and actually I think for this API it makes sense for me to keep all the functions together in a single class. I'll delete our old Function1 function and create my own as shown in below image.

Now we're going to override the route, so this is just a name for this Azure Function, and I've also chosen to give the method the same name, although it's not required that you do that. Now this is an asynchronous method, and it returns a task of IActionResult.

Inside our method, I'm starting off by writing a message to the log, and then we're reading the body of the incoming HTTP request into a string, and we're using Newtonsoft. Json to deserialize that into an instance of our TaskCreateModel class.

Next, this is the point at which we would normally add our Task item into a database, but we don't have a database yet, so for now I'm just going to use an in-memory list. So, I'll create a static list of items of type Task, as shown in line 17 and we'll put our new item into that list.

If we call this function twice in short succession, we will get two items in this list. However, if you're running in the cloud, the Azure Functions runtime will sometimes shut down if your Function App hasn't been used for a while, so it would just forget the Task items if we tried to use this technique. Also, the Azure Functions runtime can scale automatically, so there could be multiple instances running, in which case there would be multiple instances of this static list.

So, this is absolutely not a technique that you'd use in a real application, but it's fine for now while we build out this API, and we can switch to a real database later. And that's our first function done. However, the HTTP method we support is get. Then, in the body of the method things are really straightforward.

But how can we actually use that id in our code? Well, I've added another parameter to this function with the type of string and the name of id, and that allows us in the body of our method to use the id to look up in our Task Items list the item that has a matching id.

If we did find it, then we can use the OkObjectResult again to return a OK with the serialized Task item in the body. Now, we saw in the last function how we could put an id inside a route, and so we're going to use exactly the same technique for this method.

We've also got a string id parameter again, allowing us to access the value of the id within the function. Now in this function there is a bit more work to do. Then we're going to deserialize the body of the PUT request to get the values of the fields that we want to update. And, you'll notice that I'm not deserializing an entire Task entity.

I don't actually want the caller of this method to be able to update any field, such as the id or created date. So just like I did with the Create function, I've defined a custom entity called TaskUpdateModel that contains only the fields that I want users to be allowed to change.

Creating A REST API With Azure Functions

Once I've deserialized the updated values, I use them to update the actual Task item from our in-memory list, and I've decided to make providing an updated description optional to simplify using this method when all you want to do is toggle the IsCompleted status.

By now I'm hoping you can pretty much already guess what this function is going to look like. Again, we have a string id parameter, as we need to make use of the id in our method. Inside the method, we check for the existence of the item, returning a NotFoundResult if we couldn't find it, and if we did, we're simply removing it from our in-memory list and we're returning an OkResult.Connect your favorite version control system to your API, and automatically deploy commits, which makes code changes easier than ever.

There is also a almost? The sixth one is a query-string parameter which points an API version to call. API version is a query-string parameter with designated API version you should provide for service you are calling.

The same situation is with oAuth flows. I choose requests because I know it and I'm using it. It is also probably the most popular library used for handling HTTP requests. I choose adal library because it is officially a proper way to handle authentication against AAD in Python.

It is also used in Azure CLI 2. Beside of requests and adal I will also use json library for handling JSON requests bodies and calls responses and os for os environment variables handling no credentials hardcoding!

We will use token variable to extract a Bearer authorization token from the response which looks like this:. Try to decode it by yourself - you will notice the correlation between your Application ID and token's content. Then, we create query-string parameter with API version is proper version according to the documentation :. There is no request body to send. Let's create some resource group on our subscription docs :. Note change in params and urladding data and method change to requests. The response should look like this:.

Menu Close Home Subscribe.All access to storage services takes place through the storage account. The storage account is the highest level of the namespace for accessing each of the fundamental services. It is also the basis for authorization. The Blob service provides storage for entities, such as binary files and text files.

A container is like a folder, containing a set of blobs; every blob must reside in a container. The Blob service defines three types of blobs:.

Block blobs, which are optimized for streaming. This type of blob is the only blob type available with versions prior to Page blobs are available with version and later. Append blobs, which are optimized for append operations only. Append blobs are available only with version and later. Containers and blobs support user-defined metadata in the form of name-value pairs specified as headers on a request operation.

Blob names may encode a hierarchy by using a configurable path separator. The enumeration operation for blobs supports traversing the virtual hierarchy in a manner similar to that of a file system, so that you can return a set of blobs that are organized beneath a group. A block blob may be created in one of two ways. Block blobs larger than this must be uploaded as a set of blocks, each of which must be less than or equal to MB 4 MB for requests using REST versions before in size. A set of successfully uploaded blocks can be assembled in a specified order into a single contiguous blob by calling Put Block List.

Page blobs are created and initialized with a maximum size with a call to Put Blob. To write content to a page blob, you call the Put Page operation. The maximum size currently supported for a page blob is 8 TB. Append blobs can be created by calling Put Blob.

An append blob created with the Put Blob operation does not include any content. To write content to an append blob, you add blocks to the end of the blob by calling the Append Block operation. Updating or deleting existing blocks is not supported. Each block can be of different size, up to a maximum of 4 MB. The maximum size for an append blob is GB, and an append blob can include no more than 50, blocks.

Blobs support conditional update operations that may be useful for concurrency control and efficient uploading. Blobs can be read by calling the Get Blob operation. A client may read the entire blob, or an arbitrary range of bytes.
