Sample
Encoded response
HTTP/1.1 200 OK Content-Type: text/plain Transfer-Encoding: chunked 25 This is the data in the first chunk 1A and this is the second one 0
same as above, raw bytes in hex
0000-000F 48 54 54 50 2f 31 2e 31 20 32 30 30 20 4f 4b 0d HTTP/1.1 200 OK. 0010-001F 0a 43 6f 6e 74 65 6e 74 2d 54 79 70 65 3a 20 74 .Content-Type: t 0020-002F 65 78 74 2f 70 6c 61 69 6e 0d 0a 54 72 61 6e 73 ext/plain..Trans 0030-003F 66 65 72 2d 45 6e 63 6f 64 69 6e 67 3a 20 63 68 fer-Encoding: ch 0040-004F 75 6e 6b 65 64 0d 0a 0d 0a 32 35 0d 0a 54 68 69 unked....25..Thi 0050-005F 73 20 69 73 20 74 68 65 20 64 61 74 61 20 69 6e s is the data in 0060-006F 20 74 68 65 20 66 69 72 73 74 20 63 68 75 6e 6b the first chunk 0070-007F 0d 0a 0d 0a 31 41 0d 0a 61 6e 64 20 74 68 69 73 ....1A..and this 0080-008F 20 69 73 20 74 68 65 20 73 65 63 6f 6e 64 20 6f is the second o 0090-009F 6e 65 0d 0a 30 0d 0a 0d 0a ne..0....
same as above, in Java code
public static final byte[] CHUNKED_RESPONSE; static { StringBuilder sb = new StringBuilder(); sb.append("HTTP/1.1 200 OK\r\n"); sb.append("Content-Type: text/plain\r\n"); sb.append("Transfer-Encoding: chunked\r\n\r\n"); sb.append("25\r\n"); sb.append("This is the data in the first chunk\r\n"); // 37 bytes of payload // (conveniently consisting of ASCII characters only) sb.append("\r\n1A\r\n"); sb.append("and this is the second one"); // 26 bytes of payload // (conveniently consisting of ASCII characters only) sb.append("\r\n0\r\n\r\n"); CHUNKED_RESPONSE = sb.toString().getBytes(java.nio.charset.Charset.forName("US-ASCII")); }
Decoded data
This is the data in the first chunk and this is the second one
