我正在尝试从 swift 发布到 php，然后将 json 编码的数据返回给 swift。
但是，print(task.response) 为零。我的link做了它应该做的，但我的应用程序仍然以零响应。知道为什么吗？
let request = NSMutableURLRequest(URL: NSURL(string: "https://www.flashkase.com/API/createAccount.php")!)
request.HTTPMethod = "POST"
let postString = "username=frogg222"
request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) { data, response, error in
guard error == nil && data != nil else { // check for fundamental networking error
print("error=\(error)")
return
}
if let httpStatus = response as? NSHTTPURLResponse where httpStatus.statusCode != 200 { // check for http errors
print("statusCode should be 200, but is \(httpStatus.statusCode)")
print("response = \(response)")
}
let responseString = String(data: data!, encoding: NSUTF8StringEncoding)
print("responseString = \(responseString)")
}
task.resume()
print(task.response)
还有我的 PHP 文件
<?php
include($_SERVER["DOCUMENT_ROOT"] . "/inc/database.php");
$arr = [];
$arr[] = 'Reporting for duty';
if($_SERVER['REQUEST_METHOD'] == 'POST'){
$arr[] = 'Post received';
$arr[] = $_POST['username'];
}
echo json_encode($arr);
?>
更新:完成后如何查看数据？如果我取消对 sleep(3) 的注释，它将显示结果……但这显然不理想。
func postToServer(postURL: String, postString: String) {
let request = NSMutableURLRequest(URL: NSURL(string: postURL)!)
request.HTTPMethod = "POST"
request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)
let task = NSURLSession.sharedSession().dataTaskWithRequest(request){
data, response, error in
print("\(data), \(response), \(error)")
}
task.resume()
//sleep(3)
}
let sendURL: String = "https://www.flashkase.com/API/createAccount.php"
let sendData: String = "username=frogg222&email=fake123@gmail.com&password=fake1234"
postToServer(sendURL,postString: sendData)
