ios保存json与GET请求使用objective-c

我已经尝试了大多数来自stackoverflow的建议，但没有一个对我有好处。ios保存json与GET请求使用objective-c

我的客户希望在JSON与GET请求保存用户数据格式：

http://website.com/users/save.php?save={"email":"[email protected]","name":"Will Smith"}

我使用的Objective-C 请告知感谢

编辑

我的PHP文件看起来像这样：

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

所以发布不适合我。再次

Vicor作为初学者，请尽可能的解释你的问题。我想你要求将数据从应用程序发布到服务器。如果是，那么请在服务器上创建发布请求并发送数据。看看以下链接https://www.raywenderlich.com/67081/cookbook-using-nsurlsession http://stackoverflow.com/questions/19099448/send-post-request-using-nsurlsession http://stackoverflow.com/questions/34327919/post-request-with-raw-body-using-nsurlsession https://developer.apple.com/reference/foundation/urlsession –

你的问题含糊不清。你是说你想用GET请求从服务器下载数据，然后在本地保存这些数据？或者你是否说你有要发送到服务器的数据？您的网址看起来像您正试图将JSON放在网址中。你不能那样做。您可以使用查询字符串来设置少量的键值对，但无法以这种方式提供JSON有效内容。如果您要将数据发送到要使用POST的服务器，而不是GET。 –

亲爱的邓肯C，是的，我试图上传json数据到服务器，实际上是txt文件。我也很困惑。我添加了php文件，如果我只是在web浏览器中打开链接，它会很好用，但是如何在objectve-c中完成呢？谢谢 – Victor

感谢您的帮助，如果别人需要一个解决方案，这是我的代码：

.h文件中：

@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) { 

    } 
}

也增加委托方法，看看它是如何工作的：

#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); 
}
