Tim, Great tutorial. I would recommend anyone watching this to watch it all the way through. This really simplified everything I seen online. Too many people were making this really complicated but you solved that. I was originally looking for a tutorial on just getting and using data from a REST Api, after that was going to review getting images from that Api and displaying them in the app and then cycling from page to page. Tim I would recommend a different title on this video though which is why I went down the rabbit trail looking at other videos first. "C# WPF XAML REST API Tutorial - Examples, Best Practices, Memory Management, and Pitfalls" Though I have been programming for 20 years I am new to C# and I know ASP.NET uses C# and there is a difference between WPF XAML and Forms - hence my I suggest adding in those other 2 to the title.

Good video. I don't know why they have to make these packages so complicated. I'm trying to build a simple API client that sends a JSON payload with custom HTTP headers used for authentication and expects a JSON response on success or failure. It doesn't need to be asynchronous because I don't want the application doing anything else while the call is out or until the call times out. The JSON is being handled with Newtonsoft's Json.net. It just seems very difficult to find human readable documentation about system.net.http that shows how to do such a thing.
@IAmTimCorey5 жыл бұрын
I think part of it is that you are expecting to do something that isn't simple. That list of requirements entails quite a few things. Dropping async isn't really possible/necessary since the web is, by default, asynchronous. This video shows you how to connect easily to an API and get the data you need.

In this case, it was because we weren't using dependency injection (this is a .NET Framework project so it doesn't have DI built-in like ASP.NET Core projects do).

Some debugging tips about REST APIs, like using apps like Postman are invaluable too.

Yet another one of your videos that addresses something I am working on, your channel is great man thank you so much! I've seen a lot of conflicting information about HttpClient and using 1 instance of it for the life time of the app just because it implements IDisposable. I completely understand that using one instance of HttpClient in a console, windows forms, wpf, etc is fine, but what about in web mvc projects. Isnt it slightly different because if you have a static var holding the instance of HttpClient isnt that shared across everyone using your web app/site, also what is the best way to hold that once instance var for mvc? I should point out that the reason why I found your video is because I have a web app that Im building that uses a few different apis, and Im wondering how to use HttpClient instances that are kept for the lifetime of the app when Im using mvc5 and if that really is the best practice for each of the external api's Im using as each one would need a separate HttpClient as the base url address would be different
@IAmTimCorey4 жыл бұрын
So they've made the HttpClient a lot better in .NET Core. Check out this video on it: kzbin.info/www/bejne/majKlJ5noJWMgbc Basically, you use the HttpClientFactory to create clients for you (or recycle them - it doesn't matter to you which it chooses to use). That way they are safely created and disposed without overloading the system or exhausting the ports.

Pretty much. I usually save the data to a small database (SQLite, MongoDB, etc.) and the images to disk in a temp folder. I also save the API call parameters or the entire call to the database too. When a call comes in for the exact same data, I go to my database instead. You just need to know how long to cache it for based upon the resource. For example, sunrise/sunset data doesn't change for the same exact data. I could keep that forever. Stock market data changes a LOT so I might only cache the data for 15 minutes (if it was an informational application) or not at all (if it was an investing application).

This is an excellent video and has really helped me get the basics of a project I'm working on functional. However, I need to be able to parse JSON which has a more complex data structure. Basically the JSON returned from the API I'm calling contains data which I need to write to a database. The JSON will result in about 1000 individual rows being written to my DB, so can anyone direct me to a more advanced tutorial that could help understand parsing a more complex structure like this? if there is a Tim Corey vid out there (Paid or otherwise) I'd really like to know as I would definitely pay for this content.
@IAmTimCorey2 жыл бұрын
You can use the technique I showed to paste your JSON into a class definition. If you have multiple rows of data, just grab one row in your JSON to do this. Then, when you call your API, you will just get a List. The number of rows doesn't add to the complexity. It just means a bigger list.

Hi Tim. Thanks for all the great content. This may be one for the back burner or a separate resources video related to consuming rest APIs. There seem to be a wide variety of tutorial videos that relate to consuming a single endpoint, but not really anything that I've been able to find in terms of completing an "object graph". For example, if there's a theroetical API with a single product endpoint that can be retrieved via simple id key and that product has a number of related lookup id's for other related objects with separate endpoints - what would the options be in retrieving those or keeping them either cached or in memory to improve the efficiency of requests? Many thanks

Hi, I am writing an application that will continuously run on a server to make a call to an API every hour. At what point should I enter the API key. Should this be done inside the InitializeClient void or will cause security issues having this open continuously?

Hi, could not find an answer on the internet, so maybe you will help me. I heard that there is a new way of calling an API without NuGet packages. It already works without Newtonsoft but ReadAsAsync only exists in the NuGet package. If you know the answer, can you point me in the right direction?

Thank you so much. This was a very helpful video for me as I'm building out a new app that heavily utilizes JSON data. I recreated your lesson here using Xamarin and it all works quite well. However, my next big challenge is to consume JSON data which is stock price data and so my JSON has many rows that contain "high" "low" "open" "close" data. In your "Processor" class, could you demonstrate the code you would use to cycle through and deserialize that JSON into a Collection/List that can then still be accessed on the front end? There are a lot of example floating around out there, but I can't find "the one" that actually works. Any advice is appreciated.
@IAmTimCorey5 жыл бұрын
Not sure what you are looking to have demonstrated. If you have an array of objects coming back, just as for it as a List during deserialization and it will work.

Pretty much. If you have authentication on your API, you will need to do more. The TimCo Retail Manager series ( kzbin.info/aero/PLLWMQd6PeGY0bEMxObA6dtYXuJOGfxSPx ) creates an API with authentication and connects to it using WPF. That would be a good example to follow.

Hi Tim. Is there a pattern available to handle APIs that work based off a Request/Response with Events? To be more clear: The API accepts a Request Type and a Request ID, and raises an event when the request is fulfilled, referencing the Request ID. My first take on this involved a lot of globals to manage state and flow and all sorts of code in the event handlers, and having not looked at it months, I'm lost as to where I was going with it.
