Demo app

Usage

Use one of the following methods to create a Net instance

// without baseURL
let net = Net()

// with baseURL
let net = Net(baseUrlString: "http://www.puqiz.com/") 

HttpRequest

GET Request

let url = "get_path"
let params = ["integerNumber": 1, "doubleNumber": 2.0, "string": "hello"]

net.GET(url, params: params, successHandler: { responseData in
        let result = responseData.json(error: nil)
        NSLog("result \(result)")
    }, failureHandler: { error in
        NSLog("Error")
    })

// you can also make a request with absolute url
let url = "http://www.puqiz.com/get_path"
net.GET(absoluteUrl: url, params: params, successHandler: { responseData in
        let result = responseData.json(error: nil)
        NSLog("result \(result)")
    }, failureHandler: { error in
        NSLog("Error")
    })

You can also use nested params

// nested params
let params = ["string": "test",
            "integerNumber": 1,
            "floatNumber": 1.5,
            "array": [10, 20, 30],
            "dictionary": ["x": 100.0, "y": 200.0],
            "image": NetData(pngImage: img, filename: "myIcon")]

By using responseData in sucessHandler closure you can quickly

• get json dictionary
• get image
• parse xml

for GET, POST, PUT, DELETE request.

// get json dictionary from response data
let jsonDic = responseData.json(error: error)

// get image from response data
let image = responseData.image()

// parse xml with delegate
let result = responseData.parseXml(delegate: self)

POST Request

Net will automatically check your params to send request as a URL-Encoded request or a Multi-Part request. So you can easily post with number, string, image or binary data.

• URL-Encoded Request

let url = "post_path"
let params = ["string": "test", "integerNumber": 1, "floatNumber": 1.5]

net.POST(url, params: params, successHandler: { responseData in
        let result = responseData.json(error: nil)
        NSLog("result: \(result)")
    }, failureHandler: { error in
        NSLog("Error")
    })

• Multi-Part Request

let url = "post_path"
let img = UIImage(named: "puqiz_icon")

let params = ["string": "test", "integerNumber": 1,
            "icon": NetData(pngImage: img, filename: "myIcon")]

net.POST(url, params: params, successHandler: { responseData in
        let result = responseData.json(error: nil)
        NSLog("result: \(result)")
    }, failureHandler: { error in
        NSLog("Error")
    })

PUT Request

let url = "put_path"
let params = ["string": "test", "integerNumber": 1, "floatNumber": 1.5]

net.PUT(url, params: params, successHandler: { responseData in
        let result = responseData.json(error: nil)
        NSLog("result: \(result)")
    }, failureHandler: { error in
        NSLog("Error")
    })

DELETE Request

let url = "delete_path"
let params = ["id": 10]

net.DELETE(url, params: params, successHandler: { responseData in
        NSLog("result: \(result)")
    }, failureHandler: { error in
        NSLog("Error")
    })

Task

Before using download/upload function you have to call setupSession method to setup the session.

// setup session without backgroundIdentifier
net.setupSession()

To perform background downloads or uploads, you have to call setupSession method with a background identifier string. Then your download/upload tasks can be run even when the app is suspended, exits or crashes.

// setup session with backgroundIdentifier
net.setupSession(backgroundIdentifier: "com.nghialv.download")

// you can set eventsForBackgroundHandler closure
// this closure will be invoked when a task is completed in the background
net.eventsForBackgroundHandler = { urlSession in
        urlSession.getDownloadingTasksCount{ downloadingTaskCount in
        if downloadingTaskCount == 0 {
            NSLog("All files have been downloaded!")
        }
    }
}

Download

let downloadTask = net.download(absoluteUrl: url, progress: { progress in
        NSLog("progress \(progress)")
    }, completionHandler: { fileUrl, error in
        if error != nil {
            NSLog("Download failed")
        }
        else {
            NSLog("Downloaded to  : \(fileUrl)")
        }
    })

// you can control your task
downloadTask.resume()
downloadTask.suspend()
downloadTask.cancel()

Upload

• Upload with file path

let task = net.upload(absoluteUrl: url, fromFile: file, progressHandler: { progress in
        NSLog("progress \(progress)")
    }, completionHandler: { error in
        if error != nil {
            NSLog("Upload failed : \(error)")
        }
        else {
            NSLog("Upload completed")
        }
    })

• Upload with data

let yourData = NSData(...)

net.upload(absoluteUrl: url, data: yourData, progressHandler: { progress in
        NSLog("progress: \(progress)")
    }, completionHandler: { error in
        NSLog("Upload completed")
    })

• Upload with params

let image = UIImage(named: "image_file")
let imageData = UIImagePNGRepresentation(image)
let params = ["number": 1, "string": "net", "data": imageData]

net.upload(absoluteUrl: imgUrl, params: params, progressHandler: { progress in
        NSLog("progress: \(progress)")
    }, completionHandler: { error in
        NSLog("Upload completed")
    })

By default, the upload task will be performed as POST method and

• Content-Type = application/octet-stream (upload with file or data)
• Content-Type = multipart/form-data (upload with params)

But you can configure the upload task before resuming.

// set method
yourUploadTask.setHttpMethod(.PUT)

// set header field
yourUploadTask.setValue(value: "your_value", forHttpHeaderField: "header_field")

Integration

Just drag Net folder to the project tree
