LibHandler

This is a simple WIP C# LibGen Library that uses Web scraping and the "official" API to search and download books.
Since this Library is still in early development I cannot guarantee a bug-free experience.
Please note that if the LibGen API or Website changes at any point, this Library might break.
The maintainers of the different LibGen Mirrors might limit your traffic or block you altogether if you misuse this Library.
USE AT YOUR OWN RISK!

Supported Features

Feature	Description	Status
Books JSON	Get JSON Book Data of the provided IDs.	🟢 Works
Multiple Mirrors	Use the optimal Mirror for searching and downloading.	🟢 Works
Search (Title, Author, ...)	Search for books with certain filters	🟡 Works, but hasn't been tested with all filters yet

Usage / Example

Get IDs of the first 25 Books that have ".NET" in their title

string request = LibraryHandler.GetRequestFormat(SearchField.Title, ".NET", 25);
List<string> ids = LibraryHandler.GetIDs(request);

Get JSON Data of books with the provided IDs

string request = LibraryHandler.GetRequestFormat(SearchField.Title, ".NET", 25);
List<string> ids = LibraryHandler.GetIDs(request);
string json = LibraryHandler.GetJSONData(ids);
// List<Book> books = JsonConvert.DeserializeObject<List<Book>>(json);

Combined Version (This is the recommended way)

string request = LibraryHandler.GetRequestFormat(SearchField.Title, ".NET", 25);
List<Book> books = LibraryHandler.GetBooks(request);

Download Book

string download = LibraryHandler.GetDownloadLinkByMD5(books[0].md5);
// OR
string download = LibraryHandler.GetDownloadLink(books[0]);

Additional Functions

// Gets the current Mirror (The Search and Download Mirror are seperate)
Mirror mirror = LibraryHandler.GetCurrentMirror(MirrorType.SearchMirror);
// Sets the current Mirror
Mirror mirror = new Mirror()
{
    Url = "libgen.is",
    FullUrl = "https://libgen.is",
    MirrorType = MirrorType.SearchMirror,
};

Mirror downloadMirror = new Mirror()
{
    Url = "library.lol",
    FullUrl = "http://library.lol",
    MirrorType = MirrorType.DownloadMirror,
    Path = "/main/"
};

LibraryHandler.SetCurrentMirror(mirror);
LibraryHandler.SetCurrentMirror(downloadMirror);

Mirrors can also be added in the mirrors.json file
