使用 NSURL 请求时出现错误的 URL

问题描述

我正在尝试在 iPhone 4.0 SDK 中请求这种 URL(访问令牌稍作修改，因为您实际上并不需要查看它):

I'm trying to request this kind of URL in iPhone 4.0 SDK (access token slightly modified because you don't really need to see it):

https://graph.facebook.com/me?sdk=ios&sdk_version=2&access_token=123902817987|8cb9e8408d2685cef853cd80.9-747882379|UGu5NvcAHiXuGEGzkq&format=json&limit=40&until=1286619821

但我收到了这条消息:

Failed with error: Error Domain=NSURLErrorDomain Code=-1000 "bad URL" UserInfo=0x9e657a0 {NSUnderlyingError=0x9e656a0 "bad URL", NSLocalizedDescription=bad URL}

当我在 Safari 或 Chrome 中复制和粘贴时，它可以工作.我尝试按照建议将 | 替换为 %| here 但不起作用.

When I copied and pasted in Safari or Chrome, it works. I tried replacing | with %| as suggested here but doesn't work.

从终端询问它看起来像这样:

Asking it from the terminal looks like this:

curl https://graph.facebook.com/me/statuses?sdk=ios&sdk_version=2&access_token=9999955817987|8ab9e8408d2685cef.3-747882379|UGuxWDuM&format=json&limit=40&until=1286619821

有什么想法吗?

推荐答案

 NSString *strURL = [loc_address stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

            // requesting weather for this location ... 
            NSMutableURLRequest *req = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:[NSString stringWithFormat: @"http://www.google.com/ig/api?weather=%@", strURL]] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:5.0];
            [req setHTTPMethod:@"POST"];
            [req addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
