ASIHTTPRequest 身份验证

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！！！
