Method Detail

encodeUri

public static String encodeUri(String uri,
                               String encoding)
                        throws UnsupportedEncodingException
Deprecated. in favor of UriComponentsBuilder; see note about query param encoding

Encodes the given source URI into an encoded String. All various URI components are encoded according to their respective valid character sets.

Note that this method does not attempt to encode "=" and "&" characters in query parameter names and query parameter values because they cannot be parsed in a reliable way. Instead use:

  UriComponents uriComponents = UriComponentsBuilder.fromUri("/path?name={value}").buildAndExpand("a=b");
  String encodedUri = uriComponents.encode().toUriString();
 

Parameters:
uri - the URI to be encoded
encoding - the character encoding to encode to
Returns:
the encoded URI
Throws:
IllegalArgumentException - when the given uri parameter is not a valid URI
UnsupportedEncodingException - when the given encoding parameter is not supported

encodeHttpUrl

public static String encodeHttpUrl(String httpUrl,
                                   String encoding)
                            throws UnsupportedEncodingException
Deprecated. in favor of UriComponentsBuilder; see note about query param encoding

Encodes the given HTTP URI into an encoded String. All various URI components are encoded according to their respective valid character sets.

Note that this method does not support fragments (#), as these are not supposed to be sent to the server, but retained by the client.

Note that this method does not attempt to encode "=" and "&" characters in query parameter names and query parameter values because they cannot be parsed in a reliable way. Instead use:

  UriComponents uriComponents = UriComponentsBuilder.fromHttpUrl("/path?name={value}").buildAndExpand("a=b");
  String encodedUri = uriComponents.encode().toUriString();
 

Parameters:
httpUrl - the HTTP URL to be encoded
encoding - the character encoding to encode to
Returns:
the encoded URL
Throws:
IllegalArgumentException - when the given uri parameter is not a valid URI
UnsupportedEncodingException - when the given encoding parameter is not supported

encodeUriComponents

                                         String host,
                                         String port,

                                         String encoding)
