Swift iOS中的URL编码问题 [英] URL Encoding issue in swift ios

问题描述

我从服务器响应中获取的网址为:

I am getting url from my server response as:

https://baseURL/The+Man+in+the+High+Castle+Official+Trailer+%E2%80%93+2+th.m3u8

我正在将编码设为:

 videoURL = videoURL.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())!

但是avplayer无法播放此特定url. 似乎在编码URL时遇到了一些问题

but avplayer not able to play this particular url . seems like some issue in encoding URL

推荐答案

您的URL已进行百分比编码.

Your URL is already percent-encoded.

如果再次对其进行编码，则百分比部分将被编码两次，从而给出无效的URL.

If you encode it again, the percent parts will be encoded twice, giving an invalid URL.

您可以通过从网址中删除百分比编码并重新设置来看到这一点:

You can see that by removing the percent encoding from your URL and setting it again:

let base = "https://baseURL/The+Man+in+the+High+Castle+Official+Trailer+%E2%80%93+2+th.m3u8"
let decoded = base.stringByRemovingPercentEncoding!
print(decoded)
let encoded = decoded.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLFragmentAllowedCharacterSet())!
print(encoded)
