Question

我编写了以下请求代码（使用SwiftHTTP库）

func performTagRequest(detail : String){
    var request = HTTPTask()
    var formattedDetail = detail.stringByReplacingOccurrencesOfString("\"", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
    var url = "www.gifbase.com/tag/\(formattedDetail)?format=json"

    url = url.stringByAddingPercentEscapesUsingEncoding(NSUTF8StringEncoding)!
    println(url)
    request.GET(url, parameters: nil, success: {(response: HTTPResponse) in
    if response.responseObject != nil {
        let data = response.responseObject as NSData
        let str = NSString(data: data, encoding: NSUTF8StringEncoding)!
        let gifMetaArray = str.componentsSeparatedByString(",") as [String]
        //println("response: \(gifMetaArray))") //prints the HTML of the page
    }
    },failure: {(error: (NSError, HTTPResponse?)) in
        println("error: \(error)")
    })
}

在浏览器中返回有效响应（ex for "10thingsihateaboutyou"）但返回错误

error: (Error Domain=NSURLErrorDomain Code=-1002 "The operation couldn’t be completed. 
(NSURLErrorDomain error -1002.)" UserInfo=0x7ff22947b640 
{NSErrorFailingURLStringKey=www.gifbase.com/tag/10thingsihateaboutyou?format=json, 
NSUnderlyingError=0x7ff22940d550 "The operation couldn’t be completed. (kCFErrorDomainCFNetwork
error -1002.)", NSErrorFailingURLKey=www.gifbase.com/tag/10thingsihateaboutyou?format=json}, nil)

我发现错误-1002是NSURLErrorUnsupportedURL，可能是由于没有正确转义字符引起的，但是我打印的行应该是我认为的。

任何人都有这方面的经验吗？

我通过摆弄更多来找到答案。我忘记了“http：//”，因为我被桌面浏览器叮当作响......

NSURLErrorDomain代码= -1002，尽管转义限制字符
