Exception when downloading DRM content

[aetnaeus]

I get this same exception every time i try to download a DRM protected post/content.

`Exception caught: Response status code does not indicate success: 405 (METHOD NOT ALLOWED).

Are you using CDRM or your own Wildvine keys?

[sketchone]

im having the same problem and im using the cdrm

[BouncyB0uncy]

Same issue here, i don't know if it is related but chrome started blocking the Cookies yesterday. So they probs have clued onto how to block the downloader. Chrome Notification below

Reading cookie in cross-site context will be blocked in future Chrome versions Cookies with the SameSite=None; Secure and not Partitioned attributes that operate in cross-site contexts are third-party cookies. In future Chrome versions, reading third-party cookies will be blocked. This behavior protects user data from cross-site tracking. Please refer to the article linked to learn more about preparing your site to avoid potential breakage.

[melithine]

I don't think that's related at all. Try the browser extension for auth.json. and try to get your own keys if you're using CDRM.

cdrm-project has changed the site so I need to adjust the code to work with the new site which I will do later today

[kibitzz]

already fixed problem with cdrm-project, here modified function, already tested;)

Seems like this only works if run with docker, but not the .exe? any idea to solve this for .exe runs?

How would you find the path to source code?

[kibitzz]

:) download this project as zip file and unpack it - directory with unpacked files will be [path on your machine to source code]

probably you edited file APIHelper.cs but copied only the part of function, i updated comment - now it's markup is correct, replace function code in original APIHelper.cs again

[letepl]

I could build it adding System.Text.Json. to the line with the name JsonDocument:

    var doc = System.Text.Json.JsonDocument.Parse(body);

But I still get an error when it tries to download a DRM video:

Exception caught: Response status code does not indicate success: 500 (INTERNAL SERVER ERROR). StackTrace: at System.Net.Http.HttpResponseMessage.EnsureSuccessStatusCode()

[kibitzz]

sorry, code that use JsonDocument will not build without using System.Text.Json;

today something changed again on "https://cdrm-project.com/ i also geting 500 (INTERNAL SERVER ERROR). working on it

[kibitzz]

function that work today)

add on top of the file APIHelper.cs using System.Text.Json;

and replace function GetDecryptionKey

you can simply use exe that i build now OF DL.zip

Where to put this exe file?

[kibitzz]

also added some tweaks for myself:

• filter for Posts, you can download only those you added to bookmarks. for this add parameter to config.json "DownloadOnlyAddedToBookmarks": true,
• download only short videos (like tiktoks) for example Asian_sexdoll have awesome short videos, but not so awesome long. for this add parameter to config.json "DownloadOnlyVideosShorterThan": 100,

if you consider this features useful please let me know - i'll create pr for this

OF DL.zip can be used to fix already installed app, or you can get official release and replace 'OF DL.exe'

I cannot run exe when using one i compiled or one from your zip, it doesnt open

[kibitzz]

build finished successfully? what error you get when open my exe?

[CashulCwasha]

If it's the same as me - nothing. I acquired the newest version and replaced the exe with yours. No error, no window popup, nada - nothing happens.

[Ollem123]

yes nothing happens, when i use the compiled exe or you exe.

[Ollem123]

the compiled exe is only 156 KB, the original exe is 67 000KB

[kibitzz]

you can see why app fail here eventvwr.exe (windows) i tried to reproduce your case and found log event

Description: A .NET application failed. Application: OF DL.exe Path: C:\Users\38050\Downloads\OF.DL.V1.7.56\OF DL.exe Message: The application to execute does not exist: 'C:\Users\38050\Downloads\OF.DL.V1.7.56\OF DL.dll'.

now I see - published app is just one big exe file 65 mb without dll files when you build locally you get small 'OF DL.exe' and bunch of dll so you need to put all those files to your working directory

[Ollem123]

still dont work

[kibitzz]

have you tried to run app from build directory?

[Ollem123]

yes, also doesnt open

[kibitzz]

send screen of your build directory

[kibitzz]

run eventvwr.exe from cmd to view log find last error event after you try to run app (windows logs -> application) looks like this https://cdn.mos.cms.futurecdn.net/YzCNiF9cxQEbHRCsExioW8-1200-80.jpg

[Ollem123]

ah ty, it works now. I did not have .net7, only .net8. I installed 7 and now its ok.

[CashulCwasha]

Aye, cheers kibitzz. Followed your instructions to create my own exe file, slapped it with the rest of the build files, and now everything is groovy.
