Swift uses Alamofire for network requests

Alamofire is an HTTP network library written in Swift, developed by author Mattt of the former popular open source project Afnetworking, and can be used very simply for asynchronous network communication.

To get the latest version of Alamofire, go to Https://github.com/Alamofire/Alamofire and click the Download ZIP button to the right of the page. Then open the Starter project folder in the Finder, and then drag the alamofire-master folder into your main project folder.

Open the alamofire-master folder (now it's in your project folder) and then put the alamofire.xcodeprij file (note the blue icon!). Not a white icon! Drag directly into Xcode under the Alamofiredemo project, as shown in:

Next, click the Alamofiredemo item and go to the general window. Scroll to the Embedded Binaries Item, and then click the + sign below it. Select alamofire.framework, and finally Click Add to complete the Add.

Build and run your project to make sure that no errors occur, and then you can go to the next section.

To use Alamofire, you first need to import it. You need to add this ' import ' statement to each file that uses the Alamofire class and functions.

Import Alamofire

Alamofire is a powerful, Swift language HTTP Web Development toolkit. Supports various HTTP method, JSON, file upload, file download and multiple authentication methods.

Let's take a look at the specifics.

GET request

" Http://httpbin.org/get ")

Include parameters

alamofire.request (. GET,                  "http://httpbin.org/get",                  parameters: ["  Foo""bar"])

Contains Response processing

alamofire.request (. GET,                  "http://httpbin.org/get",                  parameters: ["foo  ""bar"])         in                     println ( Request)                     println (response)                     println (Error)                   }

POST request

Let parameters = [    "Foo":"Bar",    "Baz": ["a",1],    "Qux": [        "x":1,        "y":2,        "Z":3]] alamofire.request (. POST,"Http://httpbin.org/post", Parameters:parameters)

Download a file

Alamofire.download (. GET,"http://httpbin.org/stream/100", Destination: {(Temporaryurl, response)inch    ifLet Directoryurl =Nsfilemanager.defaultmanager (). Urlsfordirectory (. Documentdirectory, Indomains:. Userdomainmask) [0]                           as?Nsurl {Let pathcomponent=Response.suggestedfilenamereturndirectoryurl.urlbyappendingpathcomponent (pathcomponent)}returnTemporaryurl})

Uploading files

Let FileURL =Nsbundle.mainbundle (). Urlforresource ("Default", Withextension:"PNG") Alamofire.upload (. POST,"Http://httpbin.org/post", File:fileurl)

Download image

Now you have learned how to use Alamofire to operate the most basic network requests.

However, it is possible for the framework to fail to run on the real machine. Must be calm, please read the next article!!!
