iOS使用Objective-C使用GET請求保存JSON

Question

我已經嘗試了大多數stackoverflow的建議，但是沒有一個對我有好處。

我的客戶想要使用GET請求將用戶數據保存在json中，格式為：

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

我正在使用Objective-C，請告知謝謝

編輯

我的php文件看起來像這樣：

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

所以發布對我不起作用。 再次感謝您的幫助

萬一其他人需要解決方案，這是我的代碼：

.h文件：

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

.m文件：

-(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) {

    }
}

還添加委托方法以查看其工作方式：

#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);
}
