带POST的NSURLConnection不起作用

我正在尝试使用POST请求URLparsing参数， 但mypage.php没有收到这个参数…这是我的代码：

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://myurl/mypage.php"]]; NSString *params = [[NSString alloc]initWithFormat:@"name=%@&surname=%@&location=%@&email=%@&password=%@&gender=%@&tipo=%@", name, surname, location, email, password, gender, tipo]; [request setHTTPMethod:@"POST"]; [request setHTTPBody:[params dataUsingEncoding:NSUTF8StringEncoding]]; NSLog(params); NSURLConnection *conn=[[NSURLConnection alloc] initWithRequest:request delegate:self]; if (conn) { webData = [[NSMutableData data] retain]; } else { } 

和mypage.php

 if($_POST['name'] != "" && $_POST['email'] != "") //Here the $_POST['name'] and the $_POST['email'] are empty... 

Answer 1

你没有开始连接。 你应该用[conn start];来做[conn start];

Answer 2

尝试这个：

 NSString *params=[NSString stringWithFormat:@"name=%@&surname=%@&location=%@&email=%@&password=%@&gender=%@&tipo=%@", name, surname, location, email, password, gender, tipo]; NSData *postData=[params dataUsingEncoding:NSUTF8StringEncoding]; NSURL *url = [NSURL URLWithString:@"http://myurl/mypage.php"]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; [request setHTTPMethod:@"POST"]; [request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody:postData]; [request setValue:[NSString stringWithFormat:@"%i",postData.length] forHTTPHeaderField:@"Content-Length"]; NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; if (data!=nil) { NSString *output=[[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; NSLog(@"output: %@", output); }else{ NSLog(@"data is empty"); }
