Description

The list of methods to do URL Encode are organized into topic(s).

Method

StringencodeUrl(String url, String encoding)
Returns the ASCII-escaped representation (encoded in the specified encoding) of the given URL (encoded in UTF-16). 
if (url == null) {
    return url;
int len = url.length();
if (len == 0) {
    return url;
StringBuffer result = new StringBuffer();
...
StringencodeURLComponent(final String s)
encode URL Component 
if (s == null) {
    return "";
final StringBuilder sb = new StringBuilder();
try {
    for (int i = 0; i < s.length(); i++) {
        final char c = s.charAt(i);
        if (((c >= 'A') && (c <= 'Z')) || ((c >= 'a') && (c <= 'z')) || ((c >= '0') && (c <= '9'))
...
StringencodeUrlPath(String pathSegment)
encode Url Path 
final StringBuilder sb = new StringBuilder();
try {
    for (int i = 0; i < pathSegment.length(); i++) {
        final char c = pathSegment.charAt(i);
        if (((c >= 'A') && (c <= 'Z')) || ((c >= 'a') && (c <= 'z')) || ((c >= '0') && (c <= '9'))
                || (c == '-') || (c == '.') || (c == '_') || (c == '~')) {
            sb.append(c);
        } else {
...
StringunpaddedBase64UrlEncoded(final String unencodedString)
unpadded Base Url Encoded 
return unpaddedBase64UrlEncoded(unencodedString.getBytes());
StringuriDecode(String src)
uri Decode 
boolean query = false;
boolean decoded = false;
int length = src.length();
ByteArrayOutputStream bos = new ByteArrayOutputStream(length);
for (int i = 0; i < length; i++) {
    byte ch = (byte) src.charAt(i);
    if (ch == '?') {
        query = true;
...
StringuriDecode(String uri)
Convert a URI reference (URI or URI fragment), in US-ASCII, with escaped characters taken from UTF-8, to the corresponding Unicode string. 
try {
    byte ascii[] = uri.getBytes("US-ASCII");
    byte utf8[] = new byte[ascii.length];
    int in = 0;
    int out = 0;
    while (in < ascii.length) {
        if (ascii[in] == (byte) '%') {
            in++;
...
StringuriEncode(String uriRef)
Convert a Unicode string (which is assumed to represent a URI or URI fragment) to an RFC 2396-compliant URI reference by first converting it to bytes in UTF-8 and then encoding the resulting bytes as specified by the RFC. 
try {
    byte utf8[] = uriRef.getBytes("UTF-8");
    byte rsltAscii[] = new byte[utf8.length * 6];
    int in = 0;
    int out = 0;
    while (in < utf8.length) {
        switch (utf8[in]) {
        case (byte) 'a':
...
StringURLEncode(byte[] input)
URL Encode 
StringBuffer ret;
int i, temp;
if (input == null)
    return null;
ret = new StringBuffer();
for (i = 0; i < input.length; i++) {
    temp = input[i] & 0xff; 
    if ((temp >= 0x30 && temp <= 0x39) || 
...
StringurlEncode(byte[] rs)
url Encode 
StringBuffer sb = new StringBuffer(rs.length * 2);
for (int i = 0; i < rs.length; i++) {
    char c = (char) rs[i];
    switch (c) {
    case '_':
    case '.':
    case '*':
    case '-':
...
Stringurlencode(byte[] unencodedBytes)
Encodes an array of plain bytes into a urlencoded string 
StringBuffer buffer = new StringBuffer();
for (int i = 0; i < unencodedBytes.length; i++) {
    if (((unencodedBytes[i] >= 'a') && (unencodedBytes[i] <= 'z'))
            || ((unencodedBytes[i] >= 'A') && (unencodedBytes[i] <= 'Z'))
            || ((unencodedBytes[i] >= '0') && (unencodedBytes[i] <= '9')) || (unencodedBytes[i] == '.')
            || (unencodedBytes[i] == '-') || (unencodedBytes[i] == '*') || (unencodedBytes[i] == '_')) {
        buffer.append((char) unencodedBytes[i]);
    } else if (unencodedBytes[i] == ' ') {
