I. master the operation method of Swift – urlsession access SMS verification code


It is very practical to use swift to access SMS verification code through urlsession. Share the process of accessing SMS verification code in project development, as shown below:
`import Foundation

var semaphore = DispatchSemaphore (value: 0)

let parameters = “appId=41KYR0EB&appKey=IIWCKKSR7NOQ&phone=1561894**&templateId=1043&variables=1234″
let postData = parameters.data(using: .utf8)

var request = URLRequest(url: URL(string: “https://vip.veesing.com/smsApi/verifyCode”)!,timeoutInterval: Double.infinity)
request.addValue(“application/x-www-form-urlencoded;charset=utf-8”, forHTTPHeaderField: “Content-Type”)

request.httpMethod = “POST”
request.httpBody = postData

let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data else {

print(String(describing: error))

print(String(data: data, encoding: .utf8)!)


The above is the operation method of Swift – urlsession access SMS verification code. It’s not easy to be original. I hope you can give me a one button three connection.
