querystring.parse(str[, sep[, eq[, options]]])

• str <string> 要解析的网址查询字符串

  ¥str <string> The URL query string to parse

• sep <string> 用于在查询字符串中分隔键值对的子字符串。默认值：'&'。

  ¥sep <string> The substring used to delimit key and value pairs in the query string. Default: '&'.

• eq <string> .用于分隔查询字符串中的键和值的子字符串。默认值：'='。

  ¥eq <string>. The substring used to delimit keys and values in the query string. Default: '='.

• options <Object>

  • decodeURIComponent <Function> 当对查询字符串中的百分比编码字符进行解码时使用的函数。默认值：querystring.unescape()。

    ¥decodeURIComponent <Function> The function to use when decoding percent-encoded characters in the query string. Default: querystring.unescape().

  • maxKeys <number> 指定要解析的最大键数。指定 0 以删除键的计数限制。默认值：1000。

    ¥maxKeys <number> Specifies the maximum number of keys to parse. Specify 0 to remove key counting limitations. Default: 1000.

querystring.parse() 方法将网址查询字符串 (str) 解析为键值对的集合。

¥The querystring.parse() method parses a URL query string (str) into a collection of key and value pairs.

例如，查询字符串 'foo=bar&abc=xyz&abc=123' 被解析为：

¥For example, the query string 'foo=bar&abc=xyz&abc=123' is parsed into:

{
  "foo": "bar",
  "abc": ["xyz", "123"]
} 拷贝

querystring.parse() 方法返回的对象不是原型继承自 JavaScript Object。这意味着 obj.toString()、obj.hasOwnProperty() 等典型的 Object 方法没有定义，将不起​​作用。

¥The object returned by the querystring.parse() method does not prototypically inherit from the JavaScript Object. This means that typical Object methods such as obj.toString(), obj.hasOwnProperty(), and others are not defined and will not work.

默认情况下，查询字符串中的百分比编码字符将被假定为使用 UTF-8 编码。如果使用替代的字符编码，则需要指定替代的 decodeURIComponent 选项：

¥By default, percent-encoded characters within the query string will be assumed to use UTF-8 encoding. If an alternative character encoding is used, then an alternative decodeURIComponent option will need to be specified:

// Assuming gbkDecodeURIComponent function already exists...

querystring.parse('w=%D6%D0%CE%C4&foo=bar', null, null,
                  { decodeURIComponent: gbkDecodeURIComponent }); 拷贝
