Send HTTP Request in Swift

If you want to make send the HTTP Request in Swift.You have your URL and some parameters to the URL you want to send the Request.Firstly, you have to convert the BASEDATA into the DATA in utf8 then you make the UrlRequest and the UrlSession and create the task of your Session. here is the code how to Send HTTP Request in Swift : –

let encodedData = BASEDATA.data(using: String.Encoding.utf8)!
        let stringUrl = BASEURL + "homepage/" + "?width=" + String(format: "%f" , SCREEN_WIDTH)
        let url:URL = URL(string: stringUrl)!
        let session = URLSession.shared
        var request = URLRequest(url: url)
        request.httpMethod = "GET"
        request.cachePolicy = NSURLRequest.CachePolicy.reloadIgnoringCacheData
        let base64String = encodedData.base64EncodedString()
        request.addValue("application/json", forHTTPHeaderField: "Content-Type")
        request.addValue("application/json", forHTTPHeaderField: "Accept")
        request.setValue("Basic \(base64String)", forHTTPHeaderField: "Authorization")
        DispatchQueue.main.async(execute: {() -> Void in
            let task = session.dataTask(with: request as URLRequest) {
                (
                data, response, error) in
                
                guard let data = data, let _:URLResponse = response  , error == nil else {
                    print("error")
                    return
                }
                
                self.dataString =  String(data: data, encoding: String.Encoding.utf8)!
                if(self.dataString.characters.count > 0){
                    self.doFurtherProcessing()
                }
            }
            task.resume()
        })

let encodedData = BASEDATA.data(using: String.Encoding.utf8)!

let stringUrl = BASEURL + "homepage/" + "?width=" + String(format: "%f" , SCREEN_WIDTH)

let url:URL = URL(string: stringUrl)!

let session = URLSession.shared

var request = URLRequest(url: url)

request.httpMethod = "GET"

request.cachePolicy = NSURLRequest.CachePolicy.reloadIgnoringCacheData

let base64String = encodedData.base64EncodedString()

request.addValue("application/json", forHTTPHeaderField: "Content-Type")

request.addValue("application/json", forHTTPHeaderField: "Accept")

request.setValue("Basic \(base64String)", forHTTPHeaderField: "Authorization")

DispatchQueue.main.async(execute: {() -> Void in

let task = session.dataTask(with: request as URLRequest) {

(

data, response, error) in

guard let data = data, let _:URLResponse = response , error == nil else {

print("error")

return

}

self.dataString = String(data: data, encoding: String.Encoding.utf8)!

if(self.dataString.characters.count > 0){

self.doFurtherProcessing()

}

task.resume()

})
