Php 带Mysql的swift 3

我正在尝试用mysql在swift3中注册 但是有点不对劲， 当我运行我的应用程序并使register return msg“某些字段为空”时

在php代码中：

$fullname = htmlentities($_REQUEST["fullname"]);
$username = htmlentities($_REQUEST["username"]);
$email = htmlentities($_REQUEST["email"]);
$password = htmlentities($_REQUEST["password"]);
$phone = htmlentities($_REQUEST["phone"]) 

swift代码：

let  config = URLSessionConfiguration.default
let  session = URLSession(configuration: config)
let url = URL(string: "http://localhost/php/register.php?")
var request = URLRequest(url: url!)

request.httpMethod = "POST"

let body = "fullname=\(FirstName.text)%20\(LastName.text)&username=\(UserName.text)&email=\(Email.text)&password=\(Password.text)&phone=\(Phone.text)"

request.httpBody = body.data(using: String.Encoding.utf8)

let task = session.dataTask(with: url!) {data, response, error in

if error != nil {
 print(error!.localizedDescription)

} else {

 do {

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

   {

 print(json)

    }

} catch {
     print("error in JSONSerialization")
     }     

   }      

}
task.resume()

我想你错过了这个

let task = session.dataTask(with: request) {data, response, error in

将

url

替换为

request

我想你错过了这个

let task = session.dataTask(with: request) {data, response, error in

将

url

替换为

request

请使用

$\u POST

而不是

$\u request

，这只是一个安全提示；第二，能否将

$\u POST

记录在php文件中：

文件内容（'log.txt'，json_encode（$\u POST，json_PRETTY_PRINT））$\u POST

而不是

$\u REQUEST

文件内容（'log.txt'，json_encode（$\u POST，json_PRETTY_PRINT））并告诉我们您得到了什么
