我遇到了一點問題。我有一個從文本輸入獲取值的結構設置：struct CheckoutData: Codable { var firstName: String var lastName: String var email: String var streetAddress: String var streetAddress2: String var city: String var state: String var zipCode: String var total: Double}然后我初始化它并對其進行編碼：let checkoutData = CheckoutData( firstName: firstName.trimmingCharacters(in: .whitespacesAndNewlines), lastName: lastName.trimmingCharacters(in: .whitespacesAndNewlines), email: email.trimmingCharacters(in: .whitespacesAndNewlines), streetAddress: streetAddress.trimmingCharacters(in: .whitespacesAndNewlines), streetAddress2: streetAddress2.trimmingCharacters(in: .whitespacesAndNewlines), city: city.trimmingCharacters(in: .whitespacesAndNewlines), state: state.trimmingCharacters(in: .whitespacesAndNewlines), zipCode: zipCode.trimmingCharacters(in: .whitespacesAndNewlines), total: total)let encoder = JSONEncoder()encoder.outputFormatting = .prettyPrintedlet encoded = try! encoder.encode(checkoutData)var request = URLRequest(url: URL(string: "https://www.MyApp.com/file.php")!)request.setValue("application/json", forHTTPHeaderField: "Content-Type")request.httpMethod = "POST"request.httpBody = encodedURLSession.shared.dataTask(with: request) { data, response, error in }.resume()這是處理發送電子郵件的 PHP：$emailto = "[email protected]";$subject = "Mobile Order";$firstName = $_POST["firstName"];$lastName = $_POST["lastName"];$email = $_POST["email"];$streetAddress = $_POST["streetAddress"];$streetAddress2 = $_POST["streetAddress2"];$city = $_POST["city"];$state = $_POST["state"];$zipCode = $_POST["zipCode"];$total = $_POST["total"];然而，當我收到電子郵件時，所有變量都是空白的。我已經打印了編碼版本，它似乎編碼正確，因此它很可能位于 PHP 端。抱歉，這有點代碼轉儲，但我無法弄清楚這一點。非常感謝！

以下是通過遠程服務器上的 PHP 文件發送電子郵件的示例。
// View controller //
import UIKit
class HomeViewController: UIViewController {
@IBAction func sendTapped(_ sender: UIButton) {
DispatchQueue.global().async() {
var request = URLRequest(url: URL(string: "https://www.MyApp.com/file.php")!)
request.httpMethod = "POST"
let to = "[email protected]"
let sub = "Just testing..."
let msg = "How are you doing?"
let from = "George H. Aniston <[email protected]>"
let postString = "a=\(to)&b=\(sub)&c=\(msg)&d=\(from)"
request.httpBody = postString.data(using: .utf8)
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, error == nil else {
print("error=\(String(describing: error))")
return
}
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 {
print("statusCode should be 200, but is \(httpStatus.statusCode)")
print("response = \(String(describing: response))")
}
let responseString = String(data: data, encoding: .utf8)
print("responseString = \(String(describing: responseString))")
}
task.resume()
}
}
}
// file.php //
<?php
$to = $_POST['a'];
$sub = $_POST['b'];
$msg = $_POST['c'];
$from = $_POST['d'];
// use wordwrap() if lines are longer than 70 characters
$msg = wordwrap($msg,70);
$headers = 'From: '.$from."\r\n".
'Reply-To: '.$from."\r\n" .
'X-Mailer: PHP/' . phpversion();
// send email
mail($to, $sub, $msg, $headers);
?>
