How can I post file over Socket.

[Zective]

Hello all,

I'm a newbie of ExtendScript Toolkit CC.

A few days ago, I found out that I can use Socket in ExtendScript.

So I tried to many time for file upload to my Web Service.

But I've got failed all time then I write this post. 😉

First of all, Here is a source of my jsx file.

var conn = new Socket, reply = "";
conn.timeout = 120;

if(conn.open("localhost:80", "BINARY") && conn.connected) {
    boundary = Math.random().toString().substr(2);
    start_boundary = "--------thisisboundary" + boundary;
    boundary = "--" + start_boundary;

    textc = boundary + "\r\n"
    + "Content-Disposition: form-data; name=\"whoami\"\r\n\r\n"
    + "I don't know.";

    content = boundary + "\r\n"
    + "Content-Disposition: form-data; name=\"file\"; filename=\"test.txt\"\r\n"
    + "Content-Type: text/plain\r\n"
    + "\r\n"
    + "TEST INLINE";

    cs = "POST /upload/ HTTP/1.0\r\n"
    + "Host: localhost:80\r\n"
    + "Content-Length: " + (textc.length + content.length) + "\r\n"
    + "Connection: keep-alive\r\n"
    + "User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.66 Safari/537.36\r\n"
    + "Accept-Encoding: gzip, deflate\r\n"
    + "Content-Type: multipart/form-data; boundary=" + start_boundary + "\r\n"
    + "Accept-Charset: utf-8\r\n\r\n"
    + textc + "\r\n"
    + content + "\r\n"
    + boundary + "--\r\n\r\n";

    var logfile = new File("/C/Users/Zective/Desktop/log.txt");
    logfile.open("w");
    logfile.write(cs);
    logfile.close();

    conn.writeln(cs);

    reply = conn.read();
    alert(reply);
    conn.close();
}

And this is server-side's source. (Python Django)

import logging
from django.http import HttpResponse
from django.views.decorators.csrf import csrf_exempt

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)


@csrf_exempt  # For connection of Indesign
def upload(request):
    if request.method == 'POST':
        logger.info("----------------------------------------")
        logger.info(request.POST)
        logger.info(request.FILES)
        return HttpResponse("file lens : " + str(len(request.FILES)))
    else:
        return HttpResponse("Ha!")

Finally, the result of jsx file run.

1) log file

POST /upload/ HTTP/1.0
Host: localhost:80
Content-Length: 279
Connection: keep-alive
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.66 Safari/537.36
Accept-Encoding: gzip, deflate
Content-Type: multipart/form-data; boundary=--------thisisboundary16539001464844
Accept-Charset: utf-8

----------thisisboundary16539001464844
Content-Disposition: form-data; name="whoami"

Content-Disposition: form-data; name="file"; filename="test.txt"
Content-Type: text/plain

----------thisisboundary16539001464844--

2) alert

3) server log
