swift-srwebclient's Introduction

Swift-SRWebClient

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

Features

Success and Failure closure blocks for easy callbacks.
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.
Provides function to send Image/multipart/form-data data.
Function chaining provides us to chain methods and provides more expressive code to make web requests.
Json deserialize, when any response is a valid JSON object, otherwise return the actaul response data as string.
Headers, Timeout Interval can be set and controlled for each request.
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.

swift-srwebclient's Issues

Supporting multipart/form-data `POST` request for uploading audio files with parametres.

I'm a JS developer new to swift cannot find any library that simply uploads the audio files with paramerts.

In js it's simple as bellow:

const uploadMedia = (
  file,
  schemaId,
  fields
) => {
  const body = new FormData()
  const data = new Blob(
      JSON.stringify({
        "key": "val",
       "key2: "val2"
    {
      type: 'application/json'
    }
  )
  body.set('data', data)
  body.append('media', file)

  return axios.post("https://exaple.url/post-audio", body)
}

Update code for new swift version

Please update the code as its not working in swift 2.2

Swift - code doesn't compile

Just tried this code on a new Swift project. It has quite a few errors...

Upload operation crashes on iPod Touch

Great library. Worked fine with quite an ease. However upload operation crashes when executed on an iPod touch. (Works fine on an iPhone and iPad.)

This is the place in a code where I am experiencing a crash :

var client = SRWebClient.POST('uploadURL')
client = client.headers([HMAC Headers dictionary])
client.data(imageData, fieldName : "file", data : [:]) -> Crashes right on this line
.send({(response:AnyObject!, status:Int) -> Void in

I checked in the debugger and NONE of the fields including imageData is nil. Still scratching my head around this crash.

Thanks,
Jayesh.

Use the Unlicense instead of the MIT License

The Unlicense is better because it doesn't force me to include the MIT License in my copy.

Latest beta

Hi there!
Would like to give this a try, but getting a few errors with the latest beta.
Any chance you could update it? 👍

Thanks!

swift5: Simultaneous accesses to 0x7fde67e36510, but modification requires exclusive access

Stackoverflow told me that "Under the target's Build Settings. Select No Enforcement for Exclusive Access to Memory from Swift Compiler - Code Generation". But it still failed. Could someone help me with it?

Parsing json

I am using your library, I have to parse this json:

{"status":1,"picture":"78bd35ede6f1f996c2d05b54de5a6278.jpg"}

I tried this code:
let headersJSON = response! as! Dictionary<String, String>
println(headersJSON["picture"]!)

But I am getting following error:

Could not cast value of type '__NSCFString' (0x1036f2c50) to 'NSDictionary' (0x1036f38d0).

How can I fix it ?

Update to Swift 3 not working

i tried to migrate to swift3 with issues of 60 errors ..

Code=503 "The operation couldn’t be completed.

public func uploadImage(urlString:String, imageFile:UIImage, handler:(responseObject:AnyObject? , success: Bool?)-> Void) {
let imageData:NSData = UIImageJPEGRepresentation(imageFile, 1.0)
SRWebClient.POST(urlString)
.data(imageData, fieldName:"image", data:["apiKey":apiKey,"folder":folderName,"tags":tagNames])
.send({(response:AnyObject!, status:Int) -> Void in
println(status)
println(response)
handler(responseObject: response, success: true)
},failure:{(error:NSError!) -> Void in
println(error)
handler(responseObject: error, success: false)
})
}

Optional(<NSHTTPURLResponse: 0x7ff06053e8f0> { URL: http://img-cloud.herokuapp.com/upload } { status code: 503, headers {
"Cache-Control" = "no-cache, no-store";
Connection = "keep-alive";
"Content-Length" = 484;

Server = Cowboy;
} })
Error Domain=/upload Code=503 "The operation couldn’t be completed. (/upload error 503.)"

Any Solution or anything I'm doing it wrong?

Support for self signed certificates

For test in development, sometimes we have a server without trusted certificates.

Support for Progress Bar?

Hi there,

Do you plan to support the ability to get progress on a download or upload so someone can hook it up to a UIProgressView?

Thanks,
