iOS使用Objective-C使用GET请求保存JSON

Question

I've tried most of advises from stackoverflow but none of them was good for me.

My client wants to save user data in json with GET request in format:

http://website.com/users/save.php?save={"email":"user@domen.com","name":"Will Smith"}

I'm using objective-c Please advise Thanks

Edit

my php file looks like this:

<?php
$save = $_GET['save'];
$fp = fopen("save_users_ww.txt", "a+");
fputs($fp,$save."\r\n");
fclose($fp);
?>

so post don't work for me. Thank you for help again

In case someone else will need a solution, this is my code:

.h file:

@interface WelcomeViewController : UIViewController <NSURLConnectionDelegate>
{
NSMutableData *_responseData;
}

.m file:

-(void)postToDataBaseWithName:(NSString*)nameToPost andEmail:(NSString*)emailToPost  {
    NSString *str = [NSString stringWithFormat:@"http://website.com/users/save.php?save={\"email\":\"%@\",\"name\":\"%@\"}", emailToPost, nameToPost];
    str = [str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
    NSURL *url = [NSURL URLWithString:str];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];

    // Create url connection and fire request
    NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];

    if(conn) {

    }
}

also add delegate methods to see how it works:

#pragma mark NSURLConnection Delegate Methods

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
    // A response has been received, this is where we initialize the instance var you created
    // so that we can append data to it in the didReceiveData method
    // Furthermore, this method is called each time there is a redirect so reinitializing it
    // also serves to clear it

    NSLog(@"didReceiveResponse");
    _responseData = [[NSMutableData alloc] init];
}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
    // Append the new data to the instance variable you declared
    NSLog(@"didReceiveData");
    [_responseData appendData:data];
}

- (NSCachedURLResponse *)connection:(NSURLConnection *)connection
              willCacheResponse:(NSCachedURLResponse*)cachedResponse {
    // Return nil to indicate not necessary to store a cached response for this connection
    return nil;
}

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
    // The request is complete and data has been received
    // You can parse the stuff in your instance variable now
    NSLog(@"connectionDidFinishLoading");

}

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
    // The request has failed for some reason!
    // Check the error var
    NSLog(@"didFailWithError = %@", error);
}
