 {    "error": {       "message": "this message contains content has been blocked our security systems.",       "type": "oauthexception",       "code": 368    } } 

here code:

var canvas = document.createelement('canvas');  	var ctx = canvas.getcontext('2d');  	var img = new image;  	img.crossorigin = 'anonymous';  	img.onload = function(){  		canvas.height = img.height;  		canvas.width = img.width;  	  	ctx.drawimage(img,0,0);  	  	var dataurl = canvas.todataurl( 'image/png');  		 blob = datauritoblob(dataurl);  	  	 goon(blob);  	  	 canvas = null;   	};  	img.src = "image url";    function datauritoblob(datauri) {  var bytestring = atob(datauri.split(',')[1]);  var ab = new arraybuffer(bytestring.length);  var ia = new uint8array(ab);  (var = 0; < bytestring.length; i++) {      ia[i] = bytestring.charcodeat(i);  }  return new blob([ab], { type: 'image/png' });  }                                                           function goon(kkv){  	var formdata= new formdata();    formdata.append("access_token", "acces token");  formdata.append("message", "test message");  formdata.append("source", kkv);  formdata.append("privacy",  "{'value':'everyone'}");  try {      $.ajax({          url: 'https://graph.facebook.com/me/photos',          type: "post",          data: formdata,          processdata: false,          contenttype: false,          cache: false,          error: function (shr, status, data) {              console.log("error " + data + " status " + shr.status);          },          success: function (msg) {              //successful          }      });  } catch (e) {      console.log(e);  }   }

i using facebook graph api v2.3 access token( extended permissions)

i have tried use url parameter insted of source gave me same response

formdata.append("url", 'image url'); 

is there way without access token, wanna use facebook account on computer.if not, how can rid of error ?

no, need access token post facebook programatically. getting similar error , research seems indicate has frequency in post url. especially, if using , app , url's domain outside of app's domain. best answer either post less or use facebook's ad api, might run costs.
