URIstruktuuriin

URIstruktuuriin (Uniform Resource Identifier structure) is a standardized format for identifying resources on the internet. It is defined by RFC 3986 and consists of several components that provide a clear and consistent way to locate and access resources. The basic structure of a URI is as follows:

The scheme component indicates the protocol used to access the resource. Common schemes include HTTP, HTTPS, FTP, and MAILTO. It is followed by a colon and two forward slashes (://).

The authority component, which is optional, includes the user information, host, and port number. The user information, if present, is followed by an at sign (@). The host can be an IP address or a domain name, and the port number, if specified, is preceded by a colon (:).

The path component specifies the location of the resource on the server. It is separated from the authority component by a forward slash (/).

The query component, which is also optional, provides additional parameters for the resource. It is preceded by a question mark (?) and consists of key-value pairs separated by ampersands (&).

The fragment component, if present, points to a specific part of the resource. It is preceded by a hash symbol (#).

For example, in the URI "https://www.example.com:8080/path/to/resource?key=value#fragment", "https" is the scheme, "www.example.com" is the host, "8080" is the port, "/path/to/resource" is the path, "key=value" is the query, and "fragment" is the fragment.

URIstruktuuriin is widely used in web development, APIs, and other internet-related technologies to ensure consistent and reliable resource identification.
