Hi, I'm problem, when I add this line: request.addValue("application/json", forHTTPHeaderField: "Content-Type")
To be able to see in the output, it doesn't write, but when I take this line of code, it writes.
My code:
URLSession.shared.dataTask(with: request) { data, response, error in
if error == nil {
guard let data = data else {return}
guard let json = try? JSONSerialization.jsonObject(with: data, options: .allowFragments) else{
return
}
print("Sucesso")
print(json)
/*DispatchQueue.main.async(execute: {
do {
}catch {
}
})*/
} else {
print("Sem sucesso!")
}
} .resume()
Selecting any option will automatically load the page

Good afternoon guys, I have a project made in Xcode 9.2 and I have this problem, it doesn't record the information, I've already tested the API and ok, but I couldn't find the error yet:
@IBAction func register_click(_ sender: Any) {
//if not text
if usernameTxt.text!.isEmpty || passwordTxt.text!.isEmpty || emailTxt.text!.isEmpty || firstnameTxt.text!.isEmpty || lastnameTxt.text!.isEmpty {
usernameTxt.attributedPlaceholder = NSAttributedString(string: "username", attributes: [NSAttributedStringKey.foregroundColor: UIColor.red])
passwordTxt.attributedPlaceholder = NSAttributedString(string: "password", attributes: [NSAttributedStringKey.foregroundColor: UIColor.red])
emailTxt.attributedPlaceholder = NSAttributedString(string: "email", attributes: [NSAttributedStringKey.foregroundColor: UIColor.red])
firstnameTxt.attributedPlaceholder = NSAttributedString(string: "name", attributes: [NSAttributedStringKey.foregroundColor: UIColor.red])
lastnameTxt.attributedPlaceholder = NSAttributedString(string: "surname", attributes: [NSAttributedStringKey.foregroundColor: UIColor.red])
} else {
// if entered - create new user mysql
// remove keyboard
self.view.endEditing(true)
// url to php file
let url = URL(string: "http://localhost/Twiter/register.php")
// request to php file
var request = URLRequest(url: url!)
// method to pass data to this file (e.g. via POST)
request.httpMethod = "POST"
request.addValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
request.setValue( "application/json", forHTTPHeaderField: "Authorization")
//request.setValue("application/json; application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
// body to be appended to url
let body = "username=(usernameTxt.text!.lowercased())&password=(passwordTxt.text!)&email=(emailTxt.text!)&fullname=(firstnameTxt.text!)%20(lastnameTxt.text!)"
request.httpBody = body.data(using: .utf8) //allowLossyConversion: true
