php - iOS 向 PHP 发送数据

Question

我在向服务器上的 PHP 文件发送信息时遇到问题。我需要一些帮助，我放弃了，几乎可以放弃前面的这个问题。

IBAction:-

- (IBAction)reg:(id)sender {
    NSInteger success = 0;
    @try {
        NSString *rawStr = [NSString stringWithFormat:@"username=%@",self.txtEmail.text];
        NSData *data = [rawStr dataUsingEncoding:NSUTF8StringEncoding];

        NSURL *url = [NSURL URLWithString:@"http://something.com/register.php"];
        NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];

        [request setHTTPMethod:@"POST"];
        [request setHTTPBody:data];

        NSURLResponse *response;
        NSError *err;
        NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
        NSLog(@"responseData: %@", responseData);
    }
    @catch (NSException * e) {
        NSLog(@"Exception: %@", e);
        [self alertStatus:@"Sign in Failed." :@"Error!" :0];
    }
    if (success) {
        [self performSegueWithIdentifier:@"login_success" sender:self];
    }
}

这会发送到我服务器中的 PHP 文件

<?php
    $email      =   $_GET['username'];
    $email2      =   $_POST['username'];
    mail('thepridelagoon@gmail.com','testing' , $email,$email2);
?>

我尝试测试这两个函数以发送到我的电子邮件，但由于某种原因电子邮件是空的。我做错了吗？？请帮帮我。

正确答案是:

NSString *rawStr = [NSString stringWithFormat:@"username=%@",self.txtEmail.text];
        NSData *data = [rawStr dataUsingEncoding:NSUTF8StringEncoding];

        NSURL *url = [NSURL URLWithString:@"http://something.com/register.php"];
        NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];

        [request setHTTPMethod:@"POST"];
        [request setHTTPBody:data];

        NSURLResponse *response;
        NSError *err;
        NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
        NSLog(@"responseData: %@", responseData);
