【问题描述】：
我正在尝试使用名称和密码登录并将其传递给 Url，但我的连接失败并出现此错误。我做错了什么？
连接失败！错误 - 不受支持的 URL proyecto.lavidapirata.es/main/validate_credentials/
这是我的方法：
-(IBAction)login:(id)sender{
NSString *uName = userName.text;
NSString *uPass = userPass.text;
if([userName.text isEqualToString:@""] || [userPass.text isEqualToString:@""])
{
greeting.text = @"Input Your Value";
//[userName resignFirstResponder];
//[userPass resignFirstResponder];
return;
}
NSString *post =
[[NSString alloc] initWithFormat:@"uname=%@&pwd=%@",uName,uPass];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding
allowLossyConversion: YES];
NSString *postLength = [NSString stringWithFormat:@
"%d",[postData length]];
//Parte de la petición
NSURL *url =
[NSURL URLWithString:@"http://proyecto.lavidapirata.es"];
//proyecto.lavidapirata.es/main/validate_credentials
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
{
}
//[userName resignFirstResponder];
//[userPass resignFirstResponder];
userName.text = nil;
userPass.text = nil;
}
那是我的控制台：

您确定这与您使用的代码相同吗？从您的错误来看，您似乎缺少前面的 http://。
