我的应用程序正在使用这样的NSURL:
var url = NSURL(string: "http://www.geonames.org/search.html?q=Aïn+Béïda+Algeria&country=")
当我试图做一个从这个NSURL获取数据的任务时,如下所示:
let task = NSURLSession.sharedSession().dataTaskWithURL(url!, completionHandler: { (data: NSData!, response: NSURLResponse!, error: NSError!) -> Void in
if error == nil {
var urlContent = NSString(data: data, encoding: NSUTF8StringEncoding)
println("urlContent \(urlContent!)")
} else {
println("error mode")
}
但是尝试从该地址获取数据时出现错误,尽管当我使用野生动物园去链接时:“ http://www.geonames.org/search.html?q =Aïn+Béïda+ Algeria&country =”我可以看到数据。我该如何解决?
最佳答案
迅捷2
let original = "http://www.geonames.org/search.html?q=Aïn+Béïda+Algeria&country="
if let encodedString = original.stringByAddingPercentEncodingWithAllowedCharacters(
NSCharacterSet.URLFragmentAllowedCharacterSet()),
url = NSURL(string: encodedString)
{
print(url)
}
编码的URL现在是:
“ http://www.geonames.org/search.html?q=A%C3%AFn+B%C3%A9%C3%AFda+Algeria&country=”
并与
NSURLSession
兼容。迅捷3
let original = "http://www.geonames.org/search.html?q=Aïn+Béïda+Algeria&country="
if let encoded = original.addingPercentEncoding(withAllowedCharacters: .urlFragmentAllowed),
let url = URL(string: encoded)
{
print(url)
}
