Question

这是我快速注册页面的代码。

let headers : HTTPHeaders = ["Content-Type": "application/json"]
let postString : Parameters = ["name": "com", "email": "raj123@v", "mobile": "123", "password": "123"]
let signUpUrl = "myURL/api_register.php"

Alamofire.request(signUpUrl, method: .post, parameters: postString, encoding: JSONEncoding.default, headers: headers).responseJSON {
    response in
    switch response.result {
    case .success:
        print(response)
    case .failure(let eror):
        print(eror)
    }

这是我的php api代码：

header('Content-Type: application/json');
$return_arr = array();  
$username=mysqli_real_escape_string($link,$_POST["name"]);
$email=mysqli_real_escape_string($link,$_POST["email"]);
$mobile=mysqli_real_escape_string($link,$_POST["mobile"]);
$password=mysqli_real_escape_string($link,$_POST["password"]);

$result=mysqli_query($link,"insert into users(name,email,mob,password) values('$username','$email','$mobile','$password')");    
if(mysqli_num_rows($result))
{
$row_array['status']=true;
array_push($return_arr,$row_array);
}
else 
{
$row_array['status']=false;
array_push($return_arr,$row_array);
}
echo json_encode($return_arr);
mysqli_close($link);

Nil条目正在插入带有alamofire的数据库。实际问题在哪里，我测试了所有但是无法获得。

如果我不使用Alamofire并且此代码也不起作用：

let signUpUrl = URL(string: "myURL/api_register.php")
var request = URLRequest(url: signUpUrl!)
request.httpMethod = "POST"
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")


let postString : Parameters = ["name": "com", "email": "raj123@v", "mobile": "123", "password": "123"]
print("\(postString)")
do {
    request.httpBody = try JSONSerialization.data(withJSONObject: postString, options: .prettyPrinted)
    //print(request.description)
} catch let error {
    print(error.localizedDescription)
    displayMessage(userMessage: "Something went wrong")
    return
}

关于第二种方法，你可以使用类似的东西

let newUrl = NSURL(string:"https://.......")

let urlRequest = NSMutableURLRequest(url: newUrl! as URL, cachePolicy: .reloadIgnoringLocalAndRemoteCacheData, timeoutInterval: 60.0)

urlRequest.httpMethod = "POST"

let body = String(format:"name=%@&email=%@","picko","werr@yahoo").data(
    using: String.Encoding.utf8,allowLossyConversion: false)


urlRequest.httpBody = body

let queue = OperationQueue()

NSURLConnection.sendAsynchronousRequest(urlRequest as URLRequest, queue: queue)
{

    (response: URLResponse?,data: Data?, error: Error?) in



    /* Now we may have access to the data, but check if an error came back first or not */
    if error == nil
    {

        do {

            let responseDict = try JSONSerialization.jsonObject(with: data!, options: .allowFragments) as! [String:Any]

            print("responseDict:\(responseDict)")



        } catch let caught as NSError
        {
            print("Error in json \(caught)")
        }



    }
    else if data?.count == 0 && error == nil
    {
        print("Nothing was downloaded")
    }
    else if error != nil
    {
        print("Error happened = \(String(describing: error))")
    }


}

在swift 4中使用alamofire请求插入数据库中的空白（零）条目。请解决它
