## API
|
||
|
|
|
||
|
|
### .encode(str [, exclude, keepEncoded]) -> String
|
||
|
|
|
||
|
|
Percent-encode a string, avoiding double encoding. Don't touch `/a-zA-Z0-9/` +
|
||
|
|
excluded chars + `/%[a-fA-F0-9]{2}/` (if not disabled). Broken surrorates are
|
||
|
|
replaced with `U+FFFD`.
|
||
|
|
|
||
|
|
Params:
|
||
|
|
|
||
|
|
- __str__ - input string.
|
||
|
|
- __exclude__ - optional, `;/?:@&=+$,-_.!~*'()#`. Additional chars to keep intact
|
||
|
|
(except `/a-zA-Z0-9/`).
|
||
|
|
- __keepEncoded__ - optional, `true`. By default it skips already encoded sequences
|
||
|
|
(`/%[a-fA-F0-9]{2}/`). If set to `false`, `%` will be encoded.
|
||
|
|
|
||
|
|
|
||
|
|
### encode.defaultChars, encode.componentChars
|
||
|
|
|
||
|
|
You can use these constants as second argument to `encode` function.
|
||
|
|
|
||
|
|
- `encode.defaultChars` is the same exclude set as in the standard `encodeURI()` function
|
||
|
|
- `encode.componentChars` is the same exclude set as in the `encodeURIComponent()` function
|
||
|
|
|
||
|
|
For example, `encode('something', encode.componentChars, true)` is roughly the equivalent of
|
||
|
|
the `encodeURIComponent()` function (except `encode()` doesn't throw).
|
||
|
|
|
||
|
|
|
||
|
|
### .decode(str [, exclude]) -> String
|
||
|
|
|
||
|
|
Decode percent-encoded string. Invalid percent-encoded sequences (e.g. `%2G`)
|
||
|
|
are left as is. Invalid UTF-8 characters are replaced with `U+FFFD`.
|
||
|
|
|
||
|
|
|
||
|
|
Params:
|
||
|
|
|
||
|
|
- __str__ - input string.
|
||
|
|
- __exclude__ - set of characters to leave encoded, optional, `;/?:@&=+$,#`.
|
||
|
|
|
||
|
|
|
||
|
|
### decode.defaultChars, decode.componentChars
|
||
|
|
|
||
|
|
You can use these constants as second argument to `decode` function.
|
||
|
|
|
||
|
|
- `decode.defaultChars` is the same exclude set as in the standard `decodeURI()` function
|
||
|
|
- `decode.componentChars` is the same exclude set as in the `decodeURIComponent()` function
|
||
|
|
|
||
|
|
For example, `decode('something', decode.defaultChars)` has the same behavior as
|
||
|
|
`decodeURI('something')` on a correctly encoded input.
|
||
|
|
|
||
|
|
|
||
|
|
### .parse(url, slashesDenoteHost) -> urlObs
|
||
|
|
|
||
|
|
Parse url string. Similar to node's [url.parse](http://nodejs.org/api/url.html#url_url_parse_urlstr_parsequerystring_slashesdenotehost), but without any
|
||
|
|
normalizations and query string parse.
|
||
|
|
|
||
|
|
- __url__ - input url (string)
|
||
|
|
- __slashesDenoteHost__ - if url starts with `//`, expect a hostname after it. Optional, `false`.
|
||
|
|
|
||
|
|
Result (hash):
|
||
|
|
|
||
|
|
- protocol
|
||
|
|
- slashes
|
||
|
|
- auth
|
||
|
|
- port
|
||
|
|
- hostname
|
||
|
|
- hash
|
||
|
|
- search
|
||
|
|
- pathname
|
||
|
|
|
||
|
|
Difference with node's `url`:
|
||
|
|
|
||
|
|
1. No leading slash in paths, e.g. in `url.parse('http://foo?bar')` pathname is
|
||
|
|
``, not `/`
|
||
|
|
2. Backslashes are not replaced with slashes, so `http:\\example.org\` is
|
||
|
|
treated like a relative path
|
||
|
|
3. Trailing colon is treated like a part of the path, i.e. in
|
||
|
|
`http://example.org:foo` pathname is `:foo`
|
||
|
|
4. Nothing is URL-encoded in the resulting object, (in joyent/node some chars
|
||
|
|
in auth and paths are encoded)
|
||
|
|
5. `url.parse()` does not have `parseQueryString` argument
|
||
|
|
6. Removed extraneous result properties: `host`, `path`, `query`, etc.,
|
||
|
|
which can be constructed using other parts of the url.
|
||
|
|
|
||
|
|
|
||
|
|
### .format(urlObject)
|
||
|
|
|
||
|
|
Format an object previously obtained with `.parse()` function. Similar to node's
|
||
|
|
[url.format](http://nodejs.org/api/url.html#url_url_format_urlobj).
