发送请求到PHP服务器 [英] send Post request to PHP Server

问题描述

我尝试过使用按钮从两个文本字段发送一些数据，一旦按下按钮，我将收到一封电子邮件，其中没有我在iOS模拟器中键入的文本字段的内容。我找不到问题，请帮助我。

I tried so send some data from two textfields with my button, once i press the button I receive an E-mail without the content of the textfields which I typed in my iOS Simulator. I can not find the problem, please help me.

ViewController.h

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController
{
    UITextField * firstname;
    UITextField *lastname;
    UIButton *sendPost;
}
@property (strong, nonatomic) IBOutlet UITextField *firstname;
@property (strong, nonatomic) IBOutlet UITextField *lastname;
@property (strong, nonatomic) IBOutlet UIButton *postButtonTapped;


-(IBAction)postButtonTapped:(id)sender;


@end

ViewController.m

ViewController.m

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController
@synthesize firstname;
@synthesize lastname;

- (void)viewDidLoad
{
    [super viewDidLoad];
}

- (IBAction)postButtonTapped:(id)sender
{
    NSString *myRequestString = [NSString stringWithFormat:@"firstname=%@&lastname=%@",firstname.text,lastname.text];
    NSData *myRequestData = [NSData dataWithBytes: [myRequestString UTF8String] length: [myRequestString length]];

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL: [NSURL URLWithString: @"http://textfake.com/test/mail.php"]];

    [request setHTTPMethod: @"POST"];
    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"content-type"];
    [request setHTTPBody: myRequestData];

    NSData *returnData = [NSURLConnection sendSynchronousRequest: request returningResponse: nil error: nil];
    NSString *response = [[NSString alloc] initWithBytes:[returnData bytes] length:[returnData length] encoding:NSUTF8StringEncoding];

    NSLog(@"%@",response);
}

- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [self.firstname resignFirstResponder];
    [self.lastname resignFirstResponder];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
}

PHP代码

<?php
header("Content-type: text/html; charset=UTF-8");
$firstname = $_POST["firstname"];
$lastname = $_POST["lastname"];
$text = "not set";
if(!empty($_POST["text"])){
    $text = $_POST["text"];
}
$lat = $_POST["lat"];
$lon = $_POST["lon"];
$dieMessage =$firstname." ".$lastname."\n".$text."\n";
$dieMessage .="Lat:".$lat."\n";
$dieMessage .="Lon:".$lon;
mail("[e-mail]", "gps daten", $dieMessage);
//echo 'Email abgeschickt!';
echo $dieMessage;
?>

推荐答案

我解决了这个问题，好像有一些问题

I solved the problem, seems like it had some problems with:

[NSURL URLWithString: @"http://textfake.com/test/mail.php"]];

，应该与www一起使用。代替：

and it should be with www. instead:

[NSURL URLWithString: @"http://www.textfake.com/test/mail.php"]];
