本文整理了Java中org.apache.commons.httpclient.URI类的一些代码示例，展示了URI类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。URI类的具体详情如下：
包路径：org.apache.commons.httpclient.URI
类名称：URI

URI介绍

[英]The interface for the URI(Uniform Resource Identifiers) version of RFC 2396. This class has the purpose of supportting of parsing a URI reference to extend any specific protocols, the character encoding of the protocol to be transported and the charset of the document.

A URI is always in an "escaped" form, since escaping or unescaping a completed URI might change its semantics.

Implementers should be careful not to escape or unescape the same string more than once, since unescaping an already unescaped string might lead to misinterpreting a percent data character as another escaped character, or vice versa in the case of escaping an already escaped string.

In order to avoid these problems, data types used as follows:

URI character sequence: char 
octet sequence: byte 
original character sequence: String

So, a URI is a sequence of characters as an array of a char type, which is not always represented as a sequence of octets as an array of byte.

URI Syntactic Components

- In general, written as follows: 
Absolute URI = <scheme>:<scheme-specific-part> 
Generic URI = <scheme>://<authority><path>?<query> 
- Syntax 
absoluteURI   = scheme ":" ( hier_part | opaque_part ) 
hier_part     = ( net_path | abs_path ) [ "?" query ] 
net_path      = "//" authority [ abs_path ] 
abs_path      = "/"  path_segments

The following examples illustrate URI that are in common use.

ftp://ftp.is.co.za/rfc/rfc1808.txt 
-- ftp scheme for File Transfer Protocol services 
gopher://spinaltap.micro.umn.edu/00/Weather/California/Los%20Angeles 
-- gopher scheme for Gopher and Gopher+ Protocol services 
http://www.math.uio.no/faq/compression-faq/part1.html 
-- http scheme for Hypertext Transfer Protocol services 
mailto:mduerst@ifi.unizh.ch 
-- mailto scheme for electronic mail addresses 
news:comp.infosystems.www.servers.unix 
-- news scheme for USENET news groups and articles 
telnet://melvyl.ucop.edu/ 
-- telnet scheme for interactive services via the TELNET Protocol

Please, notice that there are many modifications from URL(RFC 1738) and relative URL(RFC 1808).

The expressions for a URI

For escaped URI forms 
- URI(char[]) // constructor 
- char[] getRawXxx() // method 
- String getEscapedXxx() // method 
- String toString() // method 
  
For unescaped URI forms 
- URI(String) // constructor 
- String getXXX() // method

[中]RFC 2396的URI（统一资源标识符）版本的接口。此类的目的是支持解析URI引用以扩展任何特定协议、要传输的协议的字符编码和文档的字符集。
URI总是以“转义”形式出现，因为转义或取消转义已完成的URI可能会改变其语义。
实现人员应该小心，不要多次转义或取消转义同一字符串，因为取消转义已经未转义的字符串可能会导致将百分比数据字符误解为另一个转义字符，或者在转义已经转义的字符串的情况下，将百分比数据字符误解为另一个转义字符。
为了避免这些问题，使用的数据类型如下：

URI character sequence: char 
octet sequence: byte 
original character sequence: String

因此，URI是一个字符序列，作为一个字符类型的数组，它并不总是表示为一个字节数组的八位字节序列。
URI语法组件

- In general, written as follows: 
Absolute URI = <scheme>:<scheme-specific-part> 
Generic URI = <scheme>://<authority><path>?<query> 
- Syntax 
absoluteURI   = scheme ":" ( hier_part | opaque_part ) 
hier_part     = ( net_path | abs_path ) [ "?" query ] 
net_path      = "//" authority [ abs_path ] 
abs_path      = "/"  path_segments

以下示例说明了常用的URI。

ftp://ftp.is.co.za/rfc/rfc1808.txt 
-- ftp scheme for File Transfer Protocol services 
gopher://spinaltap.micro.umn.edu/00/Weather/California/Los%20Angeles 
-- gopher scheme for Gopher and Gopher+ Protocol services 
http://www.math.uio.no/faq/compression-faq/part1.html 
-- http scheme for Hypertext Transfer Protocol services 
mailto:mduerst@ifi.unizh.ch 
-- mailto scheme for electronic mail addresses 
news:comp.infosystems.www.servers.unix 
-- news scheme for USENET news groups and articles 
telnet://melvyl.ucop.edu/ 
-- telnet scheme for interactive services via the TELNET Protocol

请注意，URL（RFC 1738）和相对URL（RFC 1808）有很多修改。
URI的表达式

For escaped URI forms 
- URI(char[]) // constructor 
- char[] getRawXxx() // method 
- String getEscapedXxx() // method 
- String toString() // method 
  
For unescaped URI forms 
- URI(String) // constructor 
- String getXXX() // method
