I have add basic authentication in JD2 for metalarea.org

I paste these links on JD2 but it can't crawl nothing. But inside these pages I have several hosts

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

Maybe you can't see links inside metalarea pages because you need credentials to see hidden content (host links are also hidden in spoilers)

[pspzockerscene]

Hi,

I don't think that basic-authentication will work for this forum style website.
You will probably have to extract the cookies of that website and add a link crawler rule.
Without your login credentials I won't be able to help you with that.
If you need an example, see your older thread HERE.

-psp-
EDIT

I'll be offline soon and back again tomorrow.

[nathan1]

I sent you metalarea credentials.

Just another thing if I can.
When I copy information from JD2 I see like that

Link;2010 - Crusted.rar;**External links are only visible to Support Staff****External links are only visible to Support Staff**
Link;1996 - Incomplete Minds.7z;**External links are only visible to Support Staff****External links are only visible to Support Staff**

Is possible to see also (not only) the original link of forum from which I copied the link? I mean in this way:

Link;2010 - Crusted.rar;**External links are only visible to Support Staff****External links are only visible to Support Staff**
Link;1996 - Incomplete Minds.7z;**External links are only visible to Support Staff****External links are only visible to Support Staff**

Because I need to have also forum link in informations from which that link was taken.

[Jiaz]

You can customize the CopyToClipboard Action via rightclick->context menu-> menu editor and there you can modify what is copied to clipboard
additional tags are

{url.container}
{url.origin}
{url.content}
{url.referrer}

[Jiaz]

Also check rightclick->context menu->properties->show url and double click into the url to see all known urls

[pspzockerscene]

The procedure is basically the same as described in your older forum thread but this time you need the "masession_id" cookie:

[ {
  "enabled" : true,
  "cookies" : [ ["masession_id", "CENSORED"] ],
  "updateCookies" : true,
  "logging" : false,
  "maxDecryptDepth" : 1,
  "name" : "metalarea.org example rule with cookie-login",
  "pattern" : "https?://metalarea\\.org/forum/index\\.php\\?showtopic=\\d+",
  "rule" : "DEEPDECRYPT",
  "packageNamePattern" : null,
  "passwordPattern" : null,
  "formPattern" : null,
  "deepPattern" : "Download from <a href=\"(https?://[^\"]+)\"",
  "rewriteReplaceWith" : null
} ]

Rule as plaintext for easier copy & paste:
pastebin.com/JNC85fCH
EDIT

Please keep in mind that while we always try to help, the creation of custom LinkCrawler Rules is something that you should learn!
We won't provide example rules for another 100 websites for you.
In order to learn how to do this, you need to learn how to use regular expressions first - you can use webtools such as this to practice: regex101.com

Regarding your 2nd question:
Go to Settings -> User Interface -> Downloadlink address display
Move "Data" to the top and/or deselect all others.

This will only work if you add "uncrypted" downloadlinks.
If you e.g. all .DLC containers, JD won't ever display the direct-URLs to you.

I add in this way

{type};{name};{url};{url.container};{url.origin};{packagename}

I try to test some links but after update it has some problems to recognize URLs and set <title> or don't copy <title> with CopyInformation Action

For example in this URL has mediafire link
**External links are only visible to Support Staff****External links are only visible to Support Staff**

but it don't crawl

also for this links have difficult
**External links are only visible to Support Staff****External links are only visible to Support Staff**

LOG

11.11.20 22.33.02 <--> 11.11.20 22.28.29 jdlog://6033425302851/

[nathan1]

Just another example

For example, this link is not crawled
**External links are only visible to Support Staff****External links are only visible to Support Staff**

The <title> of this URL is Carach Angren - Franckensteina Strataemontanus (2020), Symphonic Black Metal

But JD2 after update don't works

1. don't crawl links inside it
2. don't generates <title> of **External links are only visible to Support Staff****External links are only visible to Support Staff** for packet where host links are crawled or however don't copy <title> from CopyInformation (also if I set up {type};{name};{url};{url.container};{url.origin};{packagename})

[pspzockerscene]

All working fine here!
1. Working fine.
If it doesn't for you, logout in browser and login again --> Grab the new value of the cookie and put that in your rule.
Cookies can expire - yours might have expired.
Mine also expired in my test-rule and I had to renew the cookie to make it work again.
2. If you want the rule to set a package title, you'd have to define that in the rule ("packageNamePattern").
Again I'm uring you to learn how to use regular expressions but I've modified the rule once again for you to grab- and set the title:

[ {
  "enabled" : true,
  "cookies" : [ [ "masession_id", "CENSORED" ] ],
  "updateCookies" : true,
  "logging" : false,
  "maxDecryptDepth" : 1,
  "id" : 1605027636498,
  "name" : "metalarea.org example rule with cookie-login",
  "pattern" : "https?://metalarea\\.org/forum/index\\.php\\?showtopic=\\d+",
  "rule" : "DEEPDECRYPT",
  "packageNamePattern" : "<title>(.*?)</title>",
  "passwordPattern" : null,
  "formPattern" : null,
  "deepPattern" : "Download from <a href=\"(https?://[^\"]+)\"",
  "rewriteReplaceWith" : null
} ]

Rule on pastebin:
pastebin.com/Cfv2Zgv0

-psp-

[nathan1]

Ok, I refresh browser and add new cookie and now works better but not perfectly.
I give you an examples. I copy these links (I use copy selected links extension of firefox to copy URLs)

**External links are only visible to Support Staff****External links are only visible to Support Staff**
javascript:multi_page_jump('**External links are only visible to Support Staff**, 38, 30 );
**External links are only visible to Support Staff****External links are only visible to Support Staff**
**External links are only visible to Support Staff****External links are only visible to Support Staff**

JD2 crawls these links


I copy information and I see this

Link;Demoniac 1993 Satanas 666 (Rehearsal 11-1993).rar;**External links are only visible to Support Staff****External links are only visible to Support Staff** 1993 Satanas 666 (Rehearsal 11-1993);
Link;Moonblood-The Winter Falls Over The Land [Remastered](CD 2015).rar;**External links are only visible to Support Staff****External links are only visible to Support Staff** Winter Falls Over The Land [Remastered](CD 2015);
Link;st.rar;**External links are only visible to Support Staff****External links are only visible to Support Staff**

What is problem?
For st.rar "packageNamePattern" : "<title>(.*?)</title>" doesn't works.
Information that it returns to me are

Link;st.rar;**External links are only visible to Support Staff****External links are only visible to Support Staff**

At the end of line I see ;st; and not ;Moonblood-The Winter Falls Over The Land [Remastered](CD 2015);

And I don't understand why then JD2 requires also Login for metalarea if I add correctly cookie login. When I copy several links JD2 ask me login.



I give you LOG

11.11.20 23.48.47 <--> 12.11.20 00.11.04 jdlog://5333425302851/

[pspzockerscene]

Oh lol we actually had a crawler for this website from 2016.
I'll check that with Jiaz tomorrow.
The old crawler only listens for "http" URLs which is why you triggered it.

Please wait for us to re-check this tomorrow/later ...

-psp-

[pspzockerscene]

I've fixed our old metalarea plugin from 2016.
We're usually not making plugins for such simple websites anymore but you're lucky that this one still exists and didn't require a lot of work to fix.
You do not need the above linkcrawler rule anymore after the next update.

"packageNamePattern" : "<title>(.*?)</title>",

But is still possible to use "packageNamePattern" : "<title>(.*?)</title>", rule? Or just add {packagename} for CopyToClipboard Action?

[nathan1]

In your package naming I see this

Amenra - Mass VI (2017) - Metal Area - Extreme Music Portal
Amenra - Prayers 9 10 [ep] (2004) - Metal Area - Extreme Music Portal
Amenra - Mass IIII (2008) - Metal Area - Extreme Music Portal

I see that for every package is added Metal Area - Extreme Music Portal. Is possible to retrieve the real name of packet? Real names have its music genre tag in the <title> name. Look why, please

Amenra - Mass VI (2017) - Doom/Sludge/Hardcore/Drone (D)
Amenra - Prayers 9 10 [ep] (2004) - Doom/Sludge/Hardcore/Drone
Amenra - Mass Iii (2006) - Doom/Sludge/Hardcore

I ask this because when you crawl a metalarea link in JD2, for example
**External links are only visible to Support Staff****External links are only visible to Support Staff**

you can see the real <title> is this

Amenra - Mass Iii (2006), Doom/Sludge/Hardcore



and not Amenra - Mass Iii (2006) - Metal Area - Extreme Music Portal
This because relative URLs are inside that page from where JD2 crawls links.

I would like his to refer to that title

[pspzockerscene]

No.
Also, our plugin auto-does this to get the packagename.

I've updated this for the next plugin-update.
In the future, please use packagizer rules to correct package titles if you need to remove parts of them.

I try to change <tag> to retrieve correct title name but something doesn't work.

I use your packagizer rules to fix package titles and instead of

"packageNamePattern" : "<title>(.*?)</title>",

I use this

"packageNamePattern" : "<td style=\"word-wrap:break-word;\" width=\"99%\">(.*?)</td>",

[ {
  "enabled" : true,
  "cookies" : [ [ "masession_id", "CENSORED" ] ],
  "updateCookies" : true,
  "logging" : false,
  "maxDecryptDepth" : 1,
  "id" : 1605027636498,
  "name" : "metalarea.org example rule with cookie-login",
  "pattern" : "https?://metalarea\\.org/forum/index\\.php\\?showtopic=\\d+",
  "rule" : "DEEPDECRYPT",
  "packageNamePattern" : "<td style="word-wrap:break-word;" width="99%">(.*?)</td>",
  "passwordPattern" : null,
  "formPattern" : null,
  "deepPattern" : "Download from <a href="(https?://[^"]+)"",
  "rewriteReplaceWith" : null
} ]

In your update you just remove "Metal Area.. " but real name is inside this tag

<td style="word-wrap:break-word;" width="99%"> </td>

For example, in this URL
**External links are only visible to Support Staff****External links are only visible to Support Staff**


this is text that I try to set up with your packagizer rules to correct package titles

[pspzockerscene]

I've updated it once again in our plugin.

Again:
If ay plugin for a website is available, the plugin will be used and LinkCrawler Rules for the same website will be ignored.

I think that there are some problems with CopyToClipboard Action via rightclick -> context menu

I add these additional tags in (Action) Copy Information

{type};{name};{url};{url.container};{url.origin};{packagename};{url.referrer}

but JD2 don't copy also hoster's url. I try to explain: I copy these links

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

Inside these pages are links like

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

but all external hoster's url like yadi.sk or sampo.ru are missing from (Action) Copy Information. These information don't appears.
When I copy information







What additional tag do I need? These are insufficient

{type};{name};{url};{url.container};{url.origin};{packagename};{url.referrer}

The data returned by {url} will vary, depending on the url sort order in Settings > User Interface. Use {url.content} instead, to get the download url.

@psp

I follow your tips from your last post of khinsider to apply for metalarea

1. Go to Settings -> Advanced Settings -> Search for LinkCollector.dolinkcheck --> Disable this
2. Now add some- or all links.
You will notice that they will get added with a blue questionmark and without onlinestatus and with unknown filesize.

but seems that rate limit and disabling LinkCollector check is not sufficient. For example I copy about 500 metalarea urls but JDownloader still crawls a limitated number of urls (about 185)
Note: clipboard observer is enabled

LOG

01.09.22 23.15.02 <--> 01.09.22 23.52.12 jdlog://7369211370661/

I noticed that even if I have disabled the linkcollector check, JD does a check, even if partial, of the links, for example it gives me a high number of offline files.
In theory it shouldn't just show me the package name only (and this is great), but without having to check any links in it?




Why check me anyway if the files are offline even after disabling the linkcollector check? I'm only interested in coming up with the name of the packages, which it does correctly and only later can I check their status online - manually or when I download them.

In the case of metalarea it's not even clear if they have any kind of rate-limit...

Please provide the following information for us to check:
- All of those 500 URLs
- Your metalarea username + password

That's because some URLs need to be crawled first as they could return multiple URLs.
This can't be turned off as JD would simply do nothing then
Also some crawlers will do the linkcheck right away because they've accessed the URL already so yes even with disabled linkcheck, some items will be displayed as online/offline with filename/filesize information set.

No.

I'm sorry but without having your testlinks I'm unable to tell what exactly happened but it doesn't look like a bug.
I can imagine that some of your metalarea links go to a 404 error-page which the crawler will detect and display them as offline.
This is not a real "online check" but as explained the crawler needs to access the added link anyways so that is not a bug.

Also, a package in JDownloader cannot be empty it needs to contain at least one item.

[nathan1]

@psp

ok, the problem is that it does not detect many links: if you copy and paste all 500 links in bulk, JDownloader at some point freezes and "runs idle" for 1-2 minutes and in any case does not scan all the links. Instead, if you copy and paste 10-20 links it scans them and detects all 20.

What I don't understand is why the scan is conditioned by the number of links. Maybe there is some setting or timer to improve?

I sent you credentials + 500 urls metalarea links

I will take a look at it but as a poweruser you will always run into some kind of limits.
If you're frequently running into rate-limits, consider adding links with a delay of X seconds.
This should be easily possible using external scripts or even an EventScripter script:
https://support.jdownloader.org/Know...event-scripter

I'm sorry but I didn't understand neither of those two sentences.

[pspzockerscene]

It was indeed a rate-limit.
Metalarea will return http error-code 400 when that limit is reached.
For the next update I've added some measures to try to prevent running into the rate-limit.
These measures include:
- Wait 1000ms between requests
- Limit max simultan crawler instances for metalarea to 1
- Return dummy URLs for retrying in case rate-limit is hit

Bitte auf das nächste CORE-Update warten!

@psp
Thank you for this update

[pspzockerscene]

Seems like is not a classic rate limit neither is it a sophisticated one:
They're simply blocking your current session after X (about 250) requests no matter how fast these requests are performed.

I'm still working on it but I think I should be able to add auto handling and remove the requestInterval so the crawler can crawl fullspeed.

[pspzockerscene]

Done. Rate-limit for metalarea links shouldn't be a problem anymore after the next set of plugin updates.
