【问题描述】：

编码：

-(IBAction)regist:(id)sender


NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://www.alvinchuastudios.com/aNSWERED/insert_user.php"]];
// create the Method "GET" or "POST"

[request setHTTPMethod:@"POST"];


NSLog(@"the email is:%@",txtemail.text);
NSLog(@"the login is:%@",txtuser1.text);
NSLog(@"the pass is:%@",txtpass1.text);
NSLog(@"the last update by person is:%@",txtuser1.text);
NSLog(@"the user registered is:%@",datestr);
//Pass The String to server
   NSString *userUpdate =[NSString stringWithFormat:@"user_email=%@&@user_login=%@&@user_pass=%@&@last_upd_by=%@&user_registered=%@&",txtemail.text,txtuser1.text,txtpass1.text,txtuser1.text,datestr,nil];
    //NSString *userUpdate =[NSString stringWithFormat:@"user_email=gokul&@user_login=shyam&@user_pass=vaishak&@last_upd_by=shiva&user_registered=2014-01-07 16:18:43&",nil];
//Check The Value what we passed
NSLog(@"the data Details is =%@", userUpdate);

//Convert the String to Data
NSData *data1 = [userUpdate dataUsingEncoding:NSUTF8StringEncoding];

//Apply the data to the body
[request setHTTPBody:data1];

//Create the response and Error

NSError *err;
NSURLResponse *response;

NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];

NSString *resSrt = [[NSString alloc]initWithData:responseData encoding:NSASCIIStringEncoding];

//This is for Response
NSLog(@"got response==%@", resSrt);

if(resSrt)

    NSLog(@"got response");
   /* ViewController *view =[[ViewController alloc]initWithNibName:@"ViewController" bundle:NULL];

    [self presentViewController:view animated:YES completion:nil];*/




else

    NSLog(@"faield to connect");




//ViewController *view =[[ViewController alloc]initWithNibName:@"ViewController" bundle:NULL];

//[self presentViewController:view animated:YES completion:nil];

[self.navigationController popToRootViewControllerAnimated:YES];

控制台声明：

the email is:[e-mail]
the login is:ShyamSundar
the pass is:itdone
the last update by person is:ShyamSundar
the user registered is:2014-01-08 11:28:40
the data Details is =user_email=[e-mail]&@user_login=ShyamSundar&@user_pass=itdone&@last_upd_by=ShyamSundar&user_registered=2014-01-08 11:28:40&
got response==Value1 : [e-mail], Value2: , Value3: , Value4: , Value5: 2014-01-08 11:28:40"success":0,"message":"Required Fields are missing!"
got response

【问题讨论】：

好的，我想首先，史蒂夫，请告诉我们您的问题是什么，而不仅仅是“以下代码出错”

有谁知道插入数据的必填字段吗？

只需添加一些你想要的描述

是的。问题是我想通过 json post 插入服务器中的所有值。我通过上面的代码做到了。但它显示我缺少必填字段。我给了所有字段 coorectly .

我想在服务器中添加缺少的字段。

【参考方案1】：

只需替换此编码

-(IBAction)regist:(id)sender


NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://www.alvinchuastudios.com/aNSWERED/insert_user.php"]];
// create the Method "GET" or "POST"

[request setHTTPMethod:@"POST"];



//Pass The String to server
NSString *userUpdate =[NSString stringWithFormat:@"user_email=%@&user_login=%@&user_pass=%@&  last_upd_by=%@&user_registered=%@&",txtemail.text,txtuser1.text,txtpass1.text,txtuser1.text,datestr,nil];
//NSString *userUpdate =[NSString stringWithFormat:@"user_email=gokul&@user_login=shyam&@user_pass=vaishak&@last_upd_by=shiva&user_registered=2014-01-07 16:18:43&",nil];
//Check The Value what we passed
 NSLog(@"the data Details is =%@", userUpdate);

//Convert the String to Data
NSData *data1 = [userUpdate dataUsingEncoding:NSUTF8StringEncoding];

//Apply the data to the body
[request setHTTPBody:data1];

//Create the response and Error

NSError *err;
NSURLResponse *response;

NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];

NSString *resSrt = [[NSString alloc]initWithData:responseData encoding:NSASCIIStringEncoding];

//This is for Response
NSLog(@"got response==%@", resSrt);

if(resSrt)

 NSLog(@"got response");
/* ViewController *view =[[ViewController alloc]initWithNibName:@"ViewController" bundle:NULL];

  [self presentViewController:view animated:YES completion:nil];*/




else

NSLog(@"faield to connect");
