What is the magnet link prefix

Magnet link is a method for sharing files on the Internet, and it has become the preferred way for many people to share and download resources. It allows users to easily get the files they need through a unified link. However, for those who are new to magnet links, some of the terms and concepts may be confusing. One of the common questions is, what is the magnet link prefix?

Before answering this question, let us first understand the basic structure of magnet links. Magnet links consist of two parts: a prefix and a unique identifier. The prefix refers to the starting part of the link, which is used to identify the link as a magnet link. The unique identifier is usually a string that represents metadata information about the file to be downloaded or shared, such as file name, size, hash value, etc.

The determination of the magnet link prefix is ​​not a fixed standard, but is determined by various factors. However, in practical applications, specific prefixes have become widely accepted and used. The most common magnet link prefix is ​​"magnet:?".

"magnet" means that this is a magnet link, which is fixed and used to identify the type of link. "?" is a placeholder for adding parameters to the link. These parameters can provide additional information such as download speed, number of torrents, etc.

For example, a typical magnet link might look like this: magnet:?xt=urn:btih:4EE6E4B8B8A27F5CEB8612C792A72F1BA7F5BB7D&dn=movie.avi&xl=1000000

In this example, "xt" is a parameter indicating the type of file. "urn:btih" is the parameter used to identify the file hash value. "dn" represents the file name, and "xl" represents the file size.

In addition to the "magnet:?" prefix, there are some other common magnet link prefixes, such as "magnet:?xt=urn:tree:tiger". This prefix is ​​used to identify file hashes calculated using the TTH algorithm.

In short, the magnet link prefix is ​​part of the link type used to identify it. The most common prefix is ​​"magnet:?", which appears in most magnet links. Although not a fixed standard, this prefix is ​​widely accepted and used. By understanding the prefix and structure of magnet links, users can better understand and use this way of sharing files.
