jquery - Custom render returning binary data to ajax call in django-rest framework -

i making ajax call rest api , expect raw binary data.

        $.ajax({             url: 'verify',             type: 'post',             contenttype: "application/json; charset=utf-8",             data: json.stringify({                 "url": url,             }),             datatype: "application/octet-stream",             success: function(response, textstatus, jqxhr) {                 if (response) {                     try {                         //                     } catch (e) {                         displayerror(e);                     }                 }             },             error: function(jqxhr, textstatus, errorthrown) {                 // loader.remove();                 // $.unblockui();                 console.log(textstatus); // parsererror                 console.log(errorthrown); // no conversion text application/octet-stream                 var err = parseerror(jqxhr, textstatus, errorthrown);                 displayerror(err);             }         }); 

the restful api is

from rest_framework.renderers import baserenderer class binaryrenderer(baserenderer):     media_type = 'application/octet-stream'     charset = none     format = '.bin'      def render(self, data, media_type=none, renderer_context=none):         return data   rest_framework.response import response import urllib2 class myview(apiview):     renderer_classes = (binaryrenderer,)     def post(self, request):         url = request.data['url']         conn = urllib2.urlopen(url)         byte = conn.read()         conn.close()         return response({'blob':byte}) 

the server returns code 200, ajax jumps error due parseerror , errorthrown shows no conversion text application/octet-stream.

why content-type of response text, not octet-stream?

thank you

i had issue - getting binary data via ajax.

jsziputils.getbinarycontent saved day.

jsziputils.getbinarycontent("path/to/file.zip", function (err, data) { if(err) {   throw err; // or handle error } // data });
