Php 将数据发送到Objective中的服务器

我目前正试图将数据从我的xcode项目发送到我制作的服务器，但当我运行应用程序时，数据似乎没有出现在我的表中

它非常简单，允许用户输入一个名称和一条消息，当按下按钮时发送该消息。我不知道我做错了什么，有什么建议吗

以下是我的php代码：

<?php

$username = "root";
$database = "testdb";

mysql_connect('localhost', $username);

@mysql_select_db($database) or die ("Unable to find database");

$name = @$_GET["name"];
$message = @$_GET["message"];

$query = "INSERT INTO test VALUES ('', '$name', '$message')";

mysql_query($query) or die (mysql_error("error"));

mysql_close();

?>

您在Objective C中执行post，因此在PHP中，您需要使用$\u post而不是$\u GET捕获变量。

这就是您实际向PHP（post）文件发送字符串的方式。我认为剩下的应该有用。我没有试过，但它看起来很适合我

- (void) send {
    NSString *testString = @"this is a test";

    NSString *post =[NSString stringWithFormat:@"message=%@",testString];
    NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

    NSString *postLength = [NSString stringWithFormat:@"%lu", (unsigned long)[postData length]];

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
    [request setURL:[NSURL URLWithString:@"YOUR/URL/test.php"]];
    [request setHTTPMethod:@"POST"];
    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
    [request setHTTPBody:postData];
}

非常感谢你！我设法使它工作起来。然而，快速提问：如果我有多个视图控制器，它们有自己的输入框，我是否需要为每个VC创建php文件？如果您只使用收到的Post变量，一个文件就足够了：例如，

$firstFile=$\u Post[“sentFromVC1”]$第二个文件=$_POST[“sentFromVC2”]；如果（第一个文件）{echo“我们从ViewController1收到一个字符串”}如果（第二个文件）{echo”我们从ViewController2收到一个字符串”}

#import "FirstViewController.h"

@interface FirstViewController ()

@end

@implementation FirstViewController

- (void)viewDidLoad {
[super viewDidLoad];

}




-(void) postMessage:(NSString*) message withName:(NSString *) name{

if(name !=nil && message !=nil){

    NSMutableString *postString = [NSMutableString stringWithString:kPostURL];
    [postString appendString:[NSString stringWithFormat:@"?%@=%@", kName, name]];

    [postString appendString: [NSString stringWithFormat:@"&%@=%@", kMessage, message]];

    [postString setString:[postString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

    NSMutableURLRequest *request =[[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString: postString]];


    [request setHTTPMethod:@"POST"];

    postConnection =[[NSURLConnection alloc]initWithRequest:request delegate:self startImmediately:YES];


}
}

-(IBAction)post:(id)sender{
[self postMessage:messageText.text withName:nameText.text];
[messageText resignFirstResponder];
messageText.text=nil;
nameText.text=nil;

}
