HandsomeURLSession v1.2
This extension to NSURLSession gives you typed responses from HTTP requests, both asynchronous and synchronous. Exceptions are thrown if an error occurs.
The following typed responses are supported:
- UTF8 Text :
String - JSON :
[String:AnyObject] - Data :
NSData - Images :
UIImageorNSImage - XML :
NSXMLParser
CocoaPods
Install HandsomeURLSession into your project using CocoaPods.
pod 'HandsomeURLSession'
Usage
-
Get an NSURLSession
let session = NSURLSession.sharedSession()
-
Create an NSURLRequest instance for the data you want load
let request = NSURLRequest(URL: NSURL(string: "http://loripsum.net/api/plaintext")!)
Call NSURLSession for the type you are interested in, e.g. "text"
Asynchronously
let task = session.textTaskWithRequest(request) { (text:String?, response:NSHTTPURLResponse?, error:NSError?) in
// Do something interesting with text
NSLog("\(text)")
}
task.resume()Or synchronously...
let text = try session.awaitTextWithRequest(textRequest)Other Examples
Loading JSON
do {
let request = NSURLRequest(URL: NSURL(string: "http://date.jsontest.com/")!)
let json = try session.awaitJsonWithRequest(request)
let date = json["date"]
NSLog("\(date)")
}
catch let error as NSError {
NSLog("\(error.localizedDescription)")
}POSTing data without content in the response
do {
var request = NSMutableURLRequest(URL: NSURL(string: "https://mega.lotto/api")!)
request.HTTPMethod = "POST"
request.HTTPBody = try NSJSONSerialization.dataWithJSONObject([4,8,15,16,23,42], options: [])
try session.awaitVoidWithRequest(request)
print("OK")
}
catch let error as NSError {
NSLog("\(error.localizedDescription)")
}Loading XML
