PHP: setting content length of MIME message -


i have build api in php returns request java coder. have done.

header("mime-version: 1.0".$eol); header("connection: keep-alive".$eol); header("accept-encoding: gzip, deflate".$eol); header("host: host".$eol.$eol); header("content-type: multipart/related; boundary...//not sure if can show boundary".$eol); echo $res;

so, there main headers , $res variable bdy of response. form way.

$eol="\r\n"; $boundary = "boundary...//not sure if can show boundary";  $res="--".$boundary.$eol; $res .= "content-type: application/json".$eol; ob_start(); print_r($json); $result = ob_get_clean(); $data .= "content-length: ".strlen($result).$eol.$eol; $res.=$result; $res.=$eol.$eol; $res.="--".$boundary.$eol; ob_start(); readfile('/var/www/9292/inputphoto.jpg'); $result = ob_get_clean(); $res.="content-type: image/jpeg".$eol; $imagelength=strlen($result)+6; //i add +6 because of 3 $eol $res.=$eol; $res.=$result; $res.=$eol.$eol; $res.="--".$boundary.$eol; $res .= "content-type: application/octet-stream".$eol; ob_start(); readfile('/var/www/9292/1.etmpl'); $result = ob_get_clean();    $vectorlength=strlen($result)+6; $res .= "content-length: ".$vectorlength.$eol; $res.=$eol; $res.=$result; $res .= $eol.$eol; $res .= "--".$boundary."--".$eol;

here output java coder received.

http/1.1 200 ok date: wed, 22 apr 2015 12:30:47 gmt server: apache/2.4.10 (debian) mime-version: 1.0 connection: keep-alive, keep-alive accept-encoding: gzip, deflate host: 99.999.999.99:99 keep-alive: timeout=5, max=100 transfer-encoding: chunked content-type: multipart/related; boundary=--boundary...//not sure if can show boundary  2d66 --boundary...//not sure if can show boundary content-type: application/json {json can't show here}  --boundary...//not sure if can show boundary content-type: image/jpeg content-length: 1917  ����jfif``��c *��^i _|�rd�he�8�h x}�)o�d�����ƭ�2i�u�i p�$�� content of picture ----1429705906426boundary--   --boundary...//not sure if can show boundary content-type: application/octet-stream content-length: 9222  h67a831e8-5f0 content of vector --boundary...//not sure if can show boundary

rather strange don't have content length of json, set can see in code. can see strange 2d66 before first boundary. otherwise output fine, java coder can receive image, vector , json. receives mistake:

unexpected end of headers detected. higher level boundary detected or eof reached.

as understand content-length wrong somewhere.anyone experienced mime can show me mistake?

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
