Encode the URLprivate String encodeValue(String value) { return URLEncoder. encode(value, StandardCharsets. UTF_8. toString()); } @Test public void givenRequestParam_whenUTF8Scheme_thenEncode() throws Exception { Map<String, String> requestParams = new HashMap<>(); requestParams.
URL encoding converts characters into a format that can be transmitted over the Internet. URLs can only be sent over the Internet using the ASCII character-set. Since URLs often contain characters outside the ASCII set, the URL has to be converted into a valid ASCII format.
public class URLDecoder extends Object. Utility class for HTML form decoding. This class contains static methods for decoding a String from the application/x-www-form-urlencoded MIME format. The conversion process is the reverse of that used by the URLEncoder class.
Use the other encode method in URLEncoder:
URLEncoder.encode(String, String)
The first parameter is the text to encode; the second is the name of the character encoding to use (e.g., UTF-8). For example:
System.out.println(
URLEncoder.encode(
"urlParameterString",
java.nio.charset.StandardCharsets.UTF_8.toString()
)
);
You should use:
URLEncoder.encode("NAME", "UTF-8");
Use the class URLEncoder:
URLEncoder.encode(String s, String enc)
Where :
s - String to be translated.
enc - The name of a supported character encoding.
Standard charsets:
US-ASCII Seven-bit ASCII, a.k.a. ISO646-US, a.k.a. the Basic Latin block of the Unicode character set ISO-8859-1 ISO Latin Alphabet No. 1, a.k.a. ISO-LATIN-1
UTF-8 Eight-bit UCS Transformation Format
UTF-16BE Sixteen-bit UCS Transformation Format, big-endian byte order
UTF-16LE Sixteen-bit UCS Transformation Format, little-endian byte order
UTF-16 Sixteen-bit UCS Transformation Format, byte order identified by an optional byte-order mark
Example:
import java.net.URLEncoder;
String stringEncoded = URLEncoder.encode(
"This text must be encoded! aeiou áéíóú ñ, peace!", "UTF-8");
The first parameter is the String to encode; the second is the name of the character encoding to use (e.g., UTF-8).
