I don't think it's a bug so we can close this ticket. I tried to decode the URL
provided but it shows errors:
{code:java}
String testURL =
"http://uzzf.down.gsxzq.com/download/%E5%B8%B8%E7%94%A8%E9%98%80%E9%97%A8CAD%E5%9B%BE%E7%BA%B8%E5%A4%";;
System.out.println("decode: " + URLDecoder.decode(testURL));
{code}
Errors:
{code:java}
Exception in thread "main" java.lang.IllegalArgumentException: URLDecoder:
Incomplete trailing escape (%) pattern
at java.net.URLDecoder.decode(URLDecoder.java:187)
at java.net.URLDecoder.decode(URLDecoder.java:100)
at Main.main(Main.java:45)
{code}
I think the URL is incomplete as it has an extra "%" at the end and ran it
without an extra "%". It works without an issue:
{code:java}
String testURL =
"http://uzzf.down.gsxzq.com/download/%E5%B8%B8%E7%94%A8%E9%98%80%E9%97%A8CAD%E5%9B%BE%E7%BA%B8%E5%A4";;
System.out.println("decode: " + URLDecoder.decode(testURL));
URI uriBase = new URI(testURL);
System.out.println("host = " + uriBase.getHost());
{code}
Result:
{code:java}
decode: http://uzzf.down.gsxzq.com/download/常用阀门CAD图纸�
host = uzzf.down.gsxzq.com
{code}
