身份验证，需要条件也就是一个验证的服务器端，这里采用的是一个免费的网络虚拟主机，上传一个index.php的页面进行验证，附上index.php
- (void) didFinishPostlogin:(ASIHTTPRequest *) request {
NSData *data =[request responseData];
NSString * result = [NSString stringWithUTF8String:[data bytes]];
NSString * resultString = request.responseString;
NSLog(@"data:%@",result);
}
- (void) didFailedPostlogin:(ASIHTTPRequest *) request {
NSData *data =[request responseData];
NSString * result = [NSString stringWithUTF8String:[data bytes]];
NSString * resultString = request.responseString;
NSLog(@"data:%@",result);
}
//-------------- 验证 -------------
- (IBAction)login:(id)sender {
if (inUserPwd.isFirstResponder) {
[inUserPwd resignFirstResponder];
}
if (inUserName.isFirstResponder) {
[inUserName resignFirstResponder];
}
NSURL *url = [NSURL URLWithString:@"http://***/index.php"];
self.formrequest = [ASIFormDataRequest requestWithURL:url];
[formrequest setDelegate:self];
[formrequest setRequestMethod:@"POST"];
[formrequest setPostValue:inUserName.text forKey:@"username"];
[formrequest setPostValue:inUserPwd.text forKey:@"password"];
[formrequest retryUsingSuppliedCredentials];
[formrequest setDidFailSelector:@selector(didFailedPostlogin:)];
[formrequest setDidFinishSelector:@selector(didFinishPostlogin:)];
//-------当程序进入后台时继续进行request
[formrequest setShouldContinueWhenAppEntersBackground:YES];
[formrequest startAsynchronous];
[ASIHTTPRequest setSessionCookies:nil];
}
<?php
if($_POST['username'] == "111" && $_POST['password'] == "222")
{
echo '{"yes":"sucess"}';
echo '<script>';#调用javascript的跳转和弹窗
echo "alert('登录成功'); location.href='http://baidu.com'; ";
echo '</script>';
exit();#停止程序的执行
}else
{
echo '{"error":"failed"}';
};
?>
复制到txt文件，保存为index.php，上传到虚拟主机即可！！！
