                     throws URISyntaxException

Deprecated. (4.2) use URIBuilder.

Constructs a URI using all the parameters. This should be used instead of URI.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. (4.5.8) Use rewriteURI(URI, HttpHost, EnumSet)

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.

Since:

4.5.8

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.

4.5

extractHost

public static org.apache.http.HttpHost extractHost(URI uri)

Extracts target host from the given URI.

Parameters:

resolve

public static URI resolve(URI originalURI,

                   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
