Cannot send binary payload

[neilyoung]

Hi,

trying to HTTP PUT a binary buffer.

http.put('http://example.com/api/v1/target',
    'Content-Type: application/octet-stream\r\n',
    payload,
    function(code, data)
        if (code < 0) then
            print("HTTP request failed")
        else
            print(code, data)
        end
end)

The payload sent is always cut off after the first "0" byte in the payload stream. How can I send binary data?

PS: I think the problem is buried in line 194 of http_client.c

    if ( req->post_data != NULL ) /* If there is data then add Content-Length header. */ {
	os_sprintf( post_headers, "Content-Length: %d\r\n", strlen( req->post_data ) );
}

strlen takes the 0 byte seriously...

PPS: The GET API has no problem with binary data at all...

PPPS: And your module is that fixed on "strlen(blabla)", that I suppose it will not be possible at all...
