dataWithContentsOfURL不检索数据 [英] dataWithContentsOfURL doesn't retrieves data

问题描述

我正在尝试获取此页面的源代码（http://www.sanmarinocard.sm），但dataWithContentsOfURL不会检索数据。

I'm trying to get source code of this page (http://www.sanmarinocard.sm) but dataWithContentsOfURL doesn't retrieves data.

NSURL *url = [NSURL URLWithString:@"http://www.sanmarinocard.sm"];
NSData *responseData = [NSData dataWithContentsOfURL:url];
NSString *result = [[NSString alloc] initWithData:responseData encoding:NSASCIIStringEncoding];

直到几天前一切正常，但从昨天开始没有结果。

Until a few days ago everything worked fine, but since yesterday no results.

你能帮助我吗？谢谢。

推荐答案

我发现通过过滤用户代理阻止了我的应用程序。
我更改了值，现在它完美无缺。

I discovered that my application is blocked from the site by filtering the user-agent. I changed the value and now it works perfectly.

我修改了这样的代码：

NSString *userAgent = @"Mozilla/4.0 (compatible; MSIE 5.23; Mac_PowerPC)";
NSURL *url = [NSURL URLWithString: @"http://www.sanmarinocard.sm"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:url];
[request setValue:userAgent forHTTPHeaderField:@"User-Agent"];
NSURLResponse *response = nil;
NSError *error = nil;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *result = [[NSString alloc] initWithData:responseData encoding:NSASCIIStringEncoding];

谢谢！
