Swift-SRWebClient

A super simple http client framework for iOS and OSX in Swift.

Features

1. Success and Failure closure blocks for easy callbacks.

2. NSOperationQueue and NSBlockOperation to execute web requests, using which we can have a elegant way to set queuePriority, threadPriority, qualityOfService and cancel any particular Operation or all the Operations in OperationQueue.

3. Provides function to send Image/multipart/form-data data.

4. Function chaining provides us to chain methods and provides more expressive code to make web requests.

5. Json deserialize, when any response is a valid JSON object, otherwise return the actaul response data as string.

6. Headers, Timeout Interval can be set and controlled for each request.

7. Test cases for all the functionalities

Success and Failure Closures

SRWebClient.GET("http://headers.jsontest.com/", 
	success:{(response:AnyObject!, status:Int) -> Void in 
		//process success response
	}, failure:{(error:NSError!) -> Void in 
		//process failure response
	})

NSBlockOperation

var webClient = SRWebClient(method: "POST", url:"http://validate.jsontest.com/")
webClient.timeoutInterval = 30.0
webClient.priority = NSOperationQueuePriority.High
webClient.send({(response:AnyObject!, status:Int) -> Void in
		//process success response
	}, failure:{(error:NSError!) -> Void in
        //process failure response        
	})

Image Upload

var image:UIImage = UIImage(named: "apple.jpeg")
let imageData:NSData = NSData.dataWithData(UIImageJPEGRepresentation(image, 1.0))
SRWebClient.POST("http://www.tiikoni.com/tis/upload/upload.php")
	.data(imageData, fieldName:"file", data:["days":"1","title":"Swift-SRWebClient","caption":"Uploaded via Swift-SRWebClient (https://github.com/sraj/Swift-SRWebClient)"])
	.send({(response:AnyObject!, status:Int) -> Void in
		//process success response
	},failure:{(error:NSError!) -> Void in
		//process failure response
	})

Function chaining

SRWebClient.POST("http://validate.jsontest.com")
	.headers(["Content-Type":"application/x-www-form-urlencoded charset=utf-8"])
	.data(["json":"[1, 2, 3]"])
	.send({(response:AnyObject!, status:Int) -> Void in
        	//process success response	        
		}, failure:{(error:NSError!) -> Void in
        	//process failure response    
		})

JSON Deserialize

SRWebClient.GET("http://headers.jsontest.com/", 
	success:{(response:AnyObject!, status:Int) -> Void in 
		let headersJSON = response! as Dictionary<String, String>
		println(headersJSON["key"]!)
	}, failure:{(error:NSError!) -> Void in 
		println(error!.code)
	})

Timeout Interval

var webClient = SRWebClient(method: "POST", url:"http://validate.jsontest.com/")
webClient.timeoutInterval = 60.0
webClient.headers(["key":"value"])
	.send({(response:AnyObject!, status:Int) -> Void in
        //process success response
	}, failure:{(error:NSError!) -> Void in
        //process failure response
	})

TODO

• Retry mechanisam when a request fails.
• Provide a more elegant way to cancel/suspend each operation.
• Image download
• Any features requested.
