Question

我有一份把数据寄给与NSURLRequest和NSURLConnexion的PHP书。我想以员额方法发送像“Hello World”这样的数据,我希望在我的“Hello world from myPHP. .php”上显示,我没有网络服务,特别是没有PHP的经验。

我的客观法典发出了以下要求:

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL

                                URLWithString:@"http://localhost:8888/testNSURL/index.php"]

                                cachePolicy:NSURLRequestUseProtocolCachePolicy

                                timeoutInterval:60.0];

    [request setHTTPMethod:@"POST"];
    NSString *postString = @"myVariable=Hello world !";
    [request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];

    NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:request delegate:self];

    if (theConnection) {

        receiveData = [NSMutableData data]; 

}

这是我的PHP代码:

<?php
if(isset($_REQUEST["myVariable"])) {
    echo json_encode("Hello from index.php !");
}
else    echo json_encode( Request failed );
?>

我的问题是:

Is my PHP code correct?
How can I catch the echo json_encode("Hello from index.php !"); in my obj-c app?

我个人正在使用在将物品张贴到服务器时。当你从这一方法中恢复时,你就能够做这样的事情,获得服务器上的所有数据/显示价值:

- (void)requestFinished:(ASIHTTPRequest *)aRequest {
    NSData *responseData = [aRequest responseData];
    NSString *responseString = [aRequest responseString];
}

从数据信息来看,情况如下:

[[NSString alloc] initWithData:responseData encoding:NSASCIIStringEncoding]
