Ios 从服务器获取数据，NSURLConnection显示在TableView中

我快死了，请帮帮我

 scanCode = @"123";
    NSString * urlString=[NSString stringWithFormat:@"http://1-dot-digiphoto-01.appspot.com/v1/service/rest/getAlbums/QR/{%@}",scanCode];



NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:urlString]];

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

if (!conn)
{
    responseData = nil;
    NSLog(@"Connection Error");

}

检查以下代码：

NSString *urlString = [NSString stringWithFormat:@"http://1-dot-digiphoto-01.appspot.com/v1/service/rest/getAlbums/QR/{%@}",@"123"];

NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];

[theRequest addValue: @"application/x-www-form-urlencoded; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest setHTTPMethod:@"GET"];

NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

if( connection )
{
    NSLog(@"Success");
}
else
{
    NSLog(@"Failed");
}

我想发送扫描码Sitring是{123，UK111，IND111，USA111，}不确定这是否会产生影响，但您不需要NSString stringWithFormat中的花括号{}，您可以这样离开：

NSString*urlString=[NSString stringWithFormat:@”http://1-dot-digiphoto-01.appspot.com/v1/service/rest/getAlbums/QR/%@“，扫描码]@Chenna检查我的答案。它起作用了now@urnotsam我们可以用花括号表示查询字符串。他错过了发送内容模式。一旦他设置了内容模式，如下面我的答案，它一定会工作。@PREMKUMAR你是对的，我的错。你下面的答案是正确的，我会投票给其他有类似问题的人
