本文整理了Java中org.apache.http.NameValuePair类的一些代码示例，展示了NameValuePair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。NameValuePair类的具体详情如下：
包路径：org.apache.http.NameValuePair
类名称：NameValuePair

NameValuePair介绍

[英]A simple class encapsulating an attribute/value pair.

This class comforms to the generic grammar and formatting rules outlined in the Section 2.2 and Section 3.6 of RFC 2616

2.2 Basic Rules

The following rules are used throughout this specification to describe basic parsing constructs. The US-ASCII coded character set is defined by ANSI X3.4-1986.

OCTET          =  
CHAR           =  
UPALPHA        =  
LOALPHA        =  
ALPHA          = UPALPHA | LOALPHA 
DIGIT          =  
CTL            =  
CR             =  
LF             =  
SP             =  
HT             =  
            =

Many HTTP/1.1 header field values consist of words separated by LWS or special characters. These special characters MUST be in a quoted string to be used within a parameter value (as defined in section 3.6).

token          = 1* 
separators     = "(" | ")" | "" | "@" 
| "," | ";" | ":" | "\" |  
| "/" | "[" | "]" | "?" | "=" 
| "{" | "}" | SP | HT

A string of text is parsed as a single word if it is quoted using double-quote marks.

quoted-string  = (  *(qdtext | quoted-pair )  ) 
qdtext         = >

The backslash character ("") MAY be used as a single-character quoting mechanism only within quoted-string and comment constructs.

quoted-pair    = "\" CHAR

3.6 Transfer Codings

Parameters are in the form of attribute/value pairs.

parameter               = attribute "=" value 
attribute               = token 
value                   = token | quoted-string

[中]封装属性/值对的简单类。
此类符合RFC 2616的Section 2.2和{$1$}中概述的通用语法和格式规则
2.2基本规则
本规范中使用以下规则来描述基本的解析构造。US-ASCII编码字符集由ANSI X3定义。4-1986.

OCTET          =  
CHAR           =  
UPALPHA        =  
LOALPHA        =  
ALPHA          = UPALPHA | LOALPHA 
DIGIT          =  
CTL            =  
CR             =  
LF             =  
SP             =  
HT             =  
            =

许多HTTP/1.1头字段值由LWS或特殊字符分隔的单词组成。这些特殊字符必须位于带引号的字符串中，以便在参数值中使用（如第3.6节所定义）。

token          = 1* 
separators     = "(" | ")" | "" | "@" 
| "," | ";" | ":" | "\" |  
| "/" | "[" | "]" | "?" | "=" 
| "{" | "}" | SP | HT

如果使用双引号将文本字符串引用，则将其解析为单个单词。

quoted-string  = (  *(qdtext | quoted-pair )  ) 
qdtext         = >

反斜杠字符（\）只能在带引号的字符串和注释结构中用作单字符引用机制。

quoted-pair    = "\" CHAR

3.6传输编码
参数采用属性/值对的形式。

parameter               = attribute "=" value 
attribute               = token 
value                   = token | quoted-string
