Problem detect correct "filename" direct link. How to fix this problem? :(

**External links are only visible to Support Staff****External links are only visible to Support Staff**

you will need to create a package customiser rule for it
something like source url: 52mix\.cn/.+\?(.*) [with regex] && filename <jd:source:1>

I may add that this is not a bug.
You will get the same default filename when you download that item manually via browser.

Regex Match matches in JD2(Java?) Regex Engine for these links?

Boost.Regex Engine

Do not use boost regex engine, a quick google (wasn't sure what it was) its for c plus plus from what I can gather. You need to use the Java interpreter in what ever website you're testing inside. I do recommend regex101 as it has a Java8 flavour and has a easy to use interface.
The pattern I provided should work as is, I just re-checked those links and yes works fine.

Btw you do not need to escape slashes / in Java.

That's right. In Java, it is necessary to double-protect the \\ character, so we use \\ in the regex instead of a single \\. If we use this regular expression in Java code

String regex = "**External links are only visible to Support Staff**;
This regular expression will match URLs that start with "**External links are only visible to Support Staff** and contain at least one character after that fragment, followed by a question mark and anything after that. The group with dots (.+) means "match any character (except newline) at least once."

package customiser is standard regex, it does not need to be 'double' escaped, like it does inside Java code. Use the pattern I gave, check the checkbox for regex and it should work.

since the url is picked up due to directhttp plugin, its based on protocol and file extension, in this case **External links are only visible to Support Staff** the package customer rule does not need entire url structure or a pattern for the full url structure to work. The working example I gave is all you need to find the info you're looking for

and yes this thread is solved and closed.
