    • createURI

      @Deprecated public static URI createURI(String scheme, String host, int port, String path, String query, String fragment) throws URISyntaxException
      Deprecated.
      (4.2) use URIBuilder.
      Constructs a URI using all the parameters. This should be used instead of URI(String, String, String, int, String, String, String) or any of the other URI multi-argument URI constructors.
      Parameters:
      scheme - Scheme name
      host - Host name
      port - Port number
      path - Path
      query - Query
      fragment - Fragment
      Throws:
      URISyntaxException - If both a scheme and a path are given but the path is relative, if the URI string constructed from the given components violates RFC 2396, or if the authority component of the string is present but cannot be parsed as a server-based authority
    • rewriteURI

      @Deprecated public static URI rewriteURI(URI uri, org.apache.http.HttpHost target, boolean dropFragment) throws URISyntaxException
      Deprecated.
      A convenience method for creating a new URI whose scheme, host and port are taken from the target host, but whose path, query and fragment are taken from the existing URI. The fragment is only used if dropFragment is false. The path is set to "/" if not explicitly specified.
      Parameters:
      uri - Contains the path, query and fragment to use.
      target - Contains the scheme, host and port to use.
      dropFragment - True if the fragment should not be copied.
      Throws:
      URISyntaxException - If the resulting URI is invalid.
    • rewriteURI

      public static URI rewriteURI(URI uri, org.apache.http.HttpHost target, EnumSet<URIUtils.UriFlag> flags) throws URISyntaxException
      A convenience method for creating a new URI whose scheme, host and port are taken from the target host, but whose path, query and fragment are taken from the existing URI. What exactly is used and how is driven by the passed in flags. The path is set to "/" if not explicitly specified.
      Parameters:
      uri - Contains the path, query and fragment to use.
      target - Contains the scheme, host and port to use.
      flags - True if the fragment should not be copied.
      Throws:
      URISyntaxException - If the resulting URI is invalid.

    • rewriteURI

      public static URI rewriteURI(URI uri, org.apache.http.HttpHost target) throws URISyntaxException
      A convenience method for rewriteURI(URI, HttpHost, EnumSet) that always keeps the fragment.
      Throws:
      URISyntaxException
    • rewriteURI

      public static URI rewriteURI(URI uri) throws URISyntaxException
      A convenience method that creates a new URI whose scheme, host, port, path, query are taken from the existing URI, dropping any fragment or user-information. The path is set to "/" if not explicitly specified. The existing URI is returned unmodified if it has no fragment or user-information and has a path.
      Parameters:
      uri - original URI.
      Throws:
      URISyntaxException - If the resulting URI is invalid.
    • rewriteURIForRoute

      public static URI rewriteURIForRoute(URI uri, RouteInfo route) throws URISyntaxException
      A convenience method that optionally converts the original URI either to a relative or an absolute form as required by the specified route.
      Parameters:
      uri - original URI.
      Throws:
      URISyntaxException - If the resulting URI is invalid.
      Since:
      4.4
    • rewriteURIForRoute

      public static URI rewriteURIForRoute(URI uri, RouteInfo route, boolean normalizeUri) throws URISyntaxException
      A convenience method that optionally converts the original URI either to a relative or an absolute form as required by the specified route.
      Parameters:
      uri - original URI.
      Throws:
      URISyntaxException - If the resulting URI is invalid.

    • normalizeSyntax

      public static URI normalizeSyntax(URI uri) throws URISyntaxException
      Removes dot segments according to RFC 3986, section 5.2.4 and Syntax-Based Normalization according to RFC 3986, section 6.2.2.

    • extractHost

      public static org.apache.http.HttpHost extractHost(URI uri)
      Extracts target host from the given URI.
      Parameters:
      uri -
      Returns:
      the target host if the URI is absolute or null if the URI is relative or does not contain a valid host name.

    • resolve

      public static URI resolve(URI originalURI, org.apache.http.HttpHost target, List<URI> redirects) throws URISyntaxException
      Derives the interpreted (absolute) URI that was used to generate the last request. This is done by extracting the request-uri and target origin for the last request and scanning all the redirect locations for the last fragment identifier, then combining the result into a URI.
      Parameters:
      originalURI - original request before any redirects
      target - if the last URI is relative, it is resolved against this target, or null if not available.
      redirects - collection of redirect locations since the original request or null if not available.
      Returns:
      interpreted (absolute) URI
      Throws:
      URISyntaxException
