Module uri | Tarantool

Module uri

URI stands for Uniform Resource Identifier - a sequence of characters that identifies a logical or physical resource. The IETF standard says a URI string looks like this:

[scheme:]scheme-specific-part[#fragment]

A common type, a hierarchical URI, looks like this:

[scheme:][//authority][path][?query][#fragment]

For example the string 'https://tarantool.org/x.html#y' has three components:

  • https is the scheme.
  • tarantool.org/x.html is the path.
  • y is the fragment.

Tarantool’s URI module provides functions that convert URI strings into their components, or turn components into URI strings.

Below is a list of all uri functions.

Name Use
uri.parse() Get a table of URI components
uri.format() Construct a URI from components
uri.parse(URI-string)

Parse a URI string into components. Possible components are:

  • fragment
  • host
  • ipv4
  • ipv6
  • login
  • password
  • path
  • query
  • scheme
  • service
  • unix

uri.parse() is the reverse of uri.format().

Parameters:
  • URI-string – a Uniform Resource Identifier
Return:

URI components table.

Rtype:

Table

Example:

tarantool> uri = require('uri')
---
...

tarantool> uri.parse('scheme://login:password@host:service'..
'/path1/path2/path3?q1=v1&q2=v2&q3=v3:1|v3:2#fragment')
---
- login: login
  params:
    q1:
    - v1
    q2:
    - v2
    q3:
    - v3:1|v3:2
  service: service
  fragment: fragment
  password: password
  scheme: scheme
  query: q1=v1&q2=v2&q3=v3:1|v3:2
  host: host
  path: /path1/path2/path3
...
uri.format(URI-components-table[, include-password])

Form a URI string from its components. Possible components are:

  • fragment
  • host
  • ipv4
  • ipv6
  • login
  • password
  • path
  • query
  • scheme
  • service
  • unix

uri.format() is the reverse of uri.parse().

Parameters:
  • URI-components-table – a series of name=value pairs, one for each component
  • include-password – boolean. If this is supplied and is true, then the password component is rendered in clear text, otherwise it is omitted.
Return:

URI string

Rtype:

string

Example:

tarantool> uri.format({scheme='scheme', login='login', password='password', host='host',
service='service', path='/path1/path2/path3', query='q1=v1&q2=v2&q3=v3'})
---
- scheme://login@host:service/path1/path2/path3
...
