Alamofire.request(myURLString) is a function call. It scales well and makes HTTP requests synchronization a breeze. Alamofire 5 is a powerful networking library that can help with all kinds of use cases: everything from basic CRUD operations to modifying HTTP headers, sending data in the body of a request to centralizing session management with a request adapter. The agent automatically transforms JSON data into a Codable value and returns an AnyPublisher instance: The code requires some basic understanding of Combine. Here is the bird’s-eye overview of the Swift Combine framework.

The completion handler for the dataTask lets us work with the results of the call. Senior iOS Engineer at Pluto TV. Since Alamofire is a wrapper around URLSession there should be code in Alamofire there that creates a dataTask then sends it using .resume(). That’s where we could use JSONSerialization to convert the results to JSON or handle any errors. Suggestions cannot be applied while the pull request is closed. This suggestion is invalid because no changes were made to the code.

Finally, a notification gets posted to let anyone who is interested know that this task has been resumed. Now that we know what happens when DataRequest.Requestable is called, let’s figure out the rest of SessionManager.default.request(...): Before running the task, it gets packed up in an Alamofire.Request: And stored it by giving it to the delegate: By default, startsRequestImmediately is true: So request.resume() gets called. The key idea is to declare the Alamofire Session Manager as a global variable.Then to create a URLSessionConfiguration variable, set its timeout in seconds and assign it to the manager.. Every call in the project can use this configured session manager.. The syntax to make a networking request makes it a little difficult to guess what’s happening within Alamofire. To install specific pod version, specify pod version after pod name: pod 'Alamofire', '4.9.1' Step 2 – Go to Alamofire github link. I am facing a problem to send extra POST parametersparams .

After implementing the networking core, we are ready to tackle several real-world examples. Swift 5 is a game changer for networking. If we’re providing a URL string it looks like this: The same thing would look like this if we were using URLSession directly: Once we’ve set up the URLRequest and the URLSession, we’re creating a dataTask with it then using resume() to send it. The Second Way: Alamofire 5. Start by opening StarWarsOpedia.xcworkspaceinside the begin project. Alamofire is an HTTP networking library written in Swift.. SwiftyJSON makes it easy to deal with JSON data in Swift.. Steps to setup the CocoaPods. I need help with creating a custom body when sending POST request with Alamofire. func task(...) looks like we’re getting closer to where the magic happens.

There are two types of Making HTTP requests is one of first things to learn when starting iOS and macOS development with Swift 5. We’ve figured out how Alamofire makes network calls using the URLSession functions. Right-click and choose Jump to Definition. The function to make an async URL request is part of URLSession: Send POST Requests 4:15. To better understand the steps of execution, we print logs to the console: The request completes successfully and prints the list of repositories: We can cancel the request by using token: If the request is cancelled, neither value nor error is received. Build and run. Creator of Yet Another Swift Blog. To see the code for that function, mouse over it in Xcode then cmd-click on it or right-click and select “Jump to Definition”. Declare the Github repository model, which conforms to, Create a request that fetches user repositories. The promise-based HTTP agent that we’ve built is just 15 lines of code. sudo gem update --system Install CocoaPods. Our GithubAPI shares lots of code in common, that can be extracted into a new method: Now we can add the list-organization-repositories and org-members-list APIs: Let’s call both requests in parallel and combine their results: If you run the code, it will print Apple’s Github members and repositories. Let’s cmd-click on Requestable to see what those two calls do before continuing on with the function we’ve been looking at: There’s nothing special in the DataRequest.Requestable(...) initializer, it’s just the default member-wise struct initializer so it just sets the value of urlRequest. var request = URLRequest(url: requestUrl) request.httpMethod = "POST" // Set HTTP Request Header request.setValue("application/json", forHTTPHeaderField: "Accept") You can set more than one header.

So that task.resume() is the other half of that URLSession code that we’ve been looking for! The. I'm sending to API products. (Remember, .resume() can start a dataTask as well as resuming one that’s been paused.). So we’ve figured out how calling Alamofire.request ends up making a networking request using URLSession.dataTask. So if you’re having trouble debugging an API call in your app, use let request = Alamofire.request(...) then debugPrint(request) after the completion handler(s). Then it creates a DataRequest.Requestable(...) and calls originalTask.task(...) on it. Alamofire calls for a similar approach in that, one creates a router by conforming to a protocol, URLRequestConvertible. In this article we’ll implement a promise-based networking agent by using vanilla Swift 5 APIs: Codable, URLSession and the Combine framework.
