我正在尝试使用 xcode 制作登录页面。

我已阅读有关此的所有主题，并且我很确定我的应用程序已成功将用户名和密码发送到网页。

但我的问题是，当我调用响应字符串时，我仍然从网页上的登录屏幕获取源代码。当我的应用程序发送密码和用户名时，我该从哪里开始？

我使用 ASIformdatarequest 来发布用户名和密码。

这是我发送用户名和密码的代码

（Brugernavn = 用户名，Adgangskode = 密码）

    ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:@"http://coutbound.dk/login.asp"]];

    [request setPostValue:[self.bnavn text] forKey:@"Brugernavn"];
    [request setPostValue:[self.kord text] forKey:@"Adgangskode"];
    [request setDelegate:self];
    [request startAsynchronous];


}

- (void)requestFailed:(ASIHTTPRequest *)request {
    NSLog(@"Request failed: %@",[request error]);
}

- (void)requestFinished:(ASIHTTPRequest *)request {
    NSLog(@"Submitted form successfully");
    NSLog(@"Response was:");
    NSLog(@"%@",[request responseString]);
}

还有网页

为什么不为您的应用程序创建一个简单的 PHP 接口 API，如下所示？

<?php
 $username = $_REQUEST['username'];
 $password = $_REQUEST['password'];

 $result = mysql_query("SELECT * FROM users WHERE username='$username' AND password='$password'");

 $exists = mysql_num_rows($result);

 if($exists > 0) {
     $array = array('success' => 1);
 } else {
     $array = array('success' => 0);
 }

 echo json_encode($array);
?>

然后让您的应用程序侦听响应 JSON 并检查成功是 1 还是 0。如果是 1，那么您已经成功登录。否则在数据库中找到它时出错。
