iphone - 如何在iPhone应用程序中使用post将用户名和密码发送到服务器

Question

我正在制作一个 lo-gin 应用程序，我想将用户名和密码发送到服务器以进行验证如何执行此操作，我已经通过多种方式完成了，但我无法发布。我正在发布用户名和密码，但如果我直接将用户名和密码提供给 php，它就不起作用，那么如何在 iphone 中执行此操作以通过帖子发送

NSString *post = [[NSString alloc] initWithFormat:@"UserName=%@&Password=%@",username,pass];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];  

NSURL *url = [NSURL URLWithString:@"http://www.celeritas-solutions.com/emrapp/connect.php?"];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
[theRequest setHTTPMethod:@"POST"];  
theRequest setValue:postLength forHTTPHeaderField:@"Content-Length"];  
[theRequest setHTTPBody:postData];      

NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

if( theConnection )
{
    webData = [[NSMutableData data] retain];
}
else
{
    NSLog(@"Inside the else condition");
}

[nameInput resignFirstResponder];
[passInput resignFirstResponder];
nameInput.text = nil;
passInput.text = nil;

//编辑你的代码尝试这可能对你有帮助。

 NSString *post = [[NSString alloc] initWithFormat:@"UserName=%@&Password=%@",username,pass];

 NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];  

 NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];  

 NSURL *url = [NSURL URLWithString:@"http://www.celeritas-solutions.com/emrapp/connect.php?"];
 NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
 [theRequest setHTTPMethod:@"POST"];  
 [theRequest setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
 theRequest setValue:postLength forHTTPHeaderField:@"Content-Length"];  
 [theRequest setHTTPBody:postData];
