I can see the req.sessionID, it's like yeVIo68JZHLb9rvA3Js2MY6RMOo1p29S.
In the browsers console I can see the connect.sid and it looks something like this s%3AEsvCST_KXoCmyD1ixT1Elksp7WQU5Bwp.a1zlev0vJ0dNESbPCeOXZq3jsPAsAGCS7O0KTyrOTAU
I took a look at the cookie-signature library and it's not ithe same as what I see in connect.sid as it has the word "hello" in the signature.
var cookie = require('cookie-signature');
var val = cookie.sign('hello', 'tobiiscool');
val.should.equal('hello.DGDUkGlIkCzPz+C0B064FNgHdEjox7ch8tOBGslZ5QI');
How do I convert req.sessionID to connect.sid?
import * as crypto from 'crypto';
const getConnectSid = (sessionID) => {
return 's.'+sessionID+'.'+crypto.createHmac('sha256', process.env.COOKIE_SECRET) .update(sessionID).digest('base64').replace(/\=+$/, '');

Error while using json_serializable
json_serializable:json_serializable on .../sign_point_model.dart:
Error running JsonSerializableGenerator
Could not generate fromJson code for valList because of type Point<num>.
None of the provided TypeHelper instances support the defined type.
json_serializable doesn't know how to convert a Point into JSON. Since you know it's just a pair of nums you could easily convert the list yourself.
import 'dart:convert';
void main() async {
var points = [
Point(Offset(123, 456), PointType.tap),
Point(Offset(3.14159, 3.16227), PointType.move),
];
var simplified =
points.map((e) => [e.offset.dx, e.offset.dy, e.type.index]).toList();
String j = json.encode(simplified);
print(j);
var decoded = json.decode(j) as List;
var asPoints = decoded
.map((e) => Point(Offset(e[0], e[1]), PointType.values[e[2]]))
.toList();
print(asPoints);

I'm new to Stackoverflow and this will be my first question. My HTML5 player works fine on Internet Explorer but doesn't work on google chrome. I'm using a PlayReady stream which is encrypted with CENC. How can I let this work on chrome? I don't have access to the servers, they're run by third parties.
Thanks
Technically it is possible to support Widevine while you're stream is PlayReady. This is possible since you use CENC. Since you don't have access to the servers like you mentioned you can use a technique called PSSH Forging. It basically replaces the pieces to make chrome think it's Widevine, since it's CENC the CDM will decrypt the video and the stream will play.
For the sake of ease i'm going to assume you use DASH.
We have here a PSSH Box:
const widevinePSSH = '0000005c7073736800000000edef8ba979d64acea3c827dcd51d21ed0000003c080112101c773709e5ab359cbed9512bc27755fa1a087573702d63656e63221848486333436557724e5a792b32564572776e64562b673d3d2a003200';
You need to replace 1c773709e5ab359cbed9512bc27755fa with your KID.
And then at the part where you insert you'r segment in the SourceBuffer (before appendSegment) you can do the following:
let segment = args[0];
segment = new Uint8Array(segment);
const newPssh = widevinePSSH.replace('1c773709e5ab359cbed9512bc27755fa', psshKid);
const subArray = new Uint8Array(DRMUtils.stringToArrayBuffer('70737368'));
let index = 0;
const found = subArray.every((item) => {
const masterIndex = segment.indexOf(item, index);
if (~masterIndex) {
index = masterIndex;
return true;
}
});
if (found) {
return originalSourceBufferAppendBuffer.apply(this, [].slice.call(args));
}
segment = DRMUtils.uInt8ArrayToHex(segment);
// Inject the forged signal
// 70737368 = pssh
segment = segment.substr(0, segment.lastIndexOf('70737368') - 8) + newPssh + segment.substr(segment.lastIndexOf('70737368') - 8);
// Fix the MOOV atom length
// 6d6f6f76 = moov
const header = segment.substr(0, segment.indexOf('6d6f6f76') - 8);
const payload = segment.substr(segment.indexOf('6d6f6f76') - 8);
const newLength = Math.floor(payload.length / 2);
segment = header + DRMUtils.intToHex(newLength, 8) + payload.substr(8);
segment = decode(segment).b;
Sadly i can only share bits and pieces but this is roughly what you should do to get it working.
When listening to a long string output from a shell process, I receive the data in two chunks. How can I get the entire text?
Here is the code in question:
int i = 0;
Process.start('perl', ['print_text.pl']).then((Process p) {
p.stdout.transform(UTF8.decoder).listen((data) => print("${i++} ${data}"));
p.stdin.writeln('print');
});
The result from running this code is:
0 text.....
1 text.....
I've reported this issue as a bug here. You can run the sample app attached to the report to see the issue.
Try using UTF8.decodeStream().
import 'dart:io';
import 'dart:convert' show UTF8;
main() {
Process.start('ls', ['-la'])
.then((p) => UTF8.decodeStream(p.stdout))
.then((s) => print('Output:\n$s'));
}
I solved this problem by doing the following:
In the shell script, tag the start and the end of the shell's output with a random number.
In Dart, concatenate all the chunks together and use the tags to check if you got the complete result.
This solution does not require exiting the process to obtain the process result.
This is a sample code:
String text = '';
process.stdout.transform(UTF8.decoder).listen((String chunk) {
text = text + chunk;
if (text.substring(errors.length - 1) == text.substring(0, 1)) {
text = text.replaceFirst(new RegExp(r'^(\d+)'), '').replaceFirst(new RegExp(r'(\d+)$'), '');
// use process result then clear text value for subsequent process results
text = '';
}
});
It's not clear what the actual question is but I assume this is what you are looking for:
import 'dart:io';
import 'dart:convert' show UTF8;
void main() {
int i = 0;
String text = '';
Process.start('perl', ['analyze.pl']).then((p) {
p.stdout.transform(UTF8.decoder).listen((data) =>
text += data);
p.exitCode.then((_) => print(text));
});
}
Please be kind, I'm new to Fiddler
My purpose:I want to use Fiddler as a Google search filter
Summary:
I'm tired of manually adding "dog" every time I use Google.I do not want the "dog" appearing in my search results.
For example:
//www.google.com/search?q=cat+-dog
//www.google.com/search?q=baseball+-dog
CODE:
dog replaced with -torrent-watch-download
// ==UserScript==
// #name Tamper with Google Results
// #namespace http://superuser.com/users/145045/krowe
// #version 0.1
// #description This just modifies google results to exclude certain things.
// #match http://*.google.com
// #match https://*.google.com
// #copyright 2014+, KRowe
// ==/UserScript==
function GM_main () {
window.onload = function () {
var targ = window.location;
if(targ && targ.href && targ.href.match('https?:\/\/www.google.com/.+#q=.+') && targ.href.search("/+-torrent/+-watch/+-download")==-1) {
targ.href = targ.href +"+-torrent+-watch+-download";
}
};
}
//-- This is a standard-ish utility function:
function addJS_Node(text, s_URL, funcToRun, runOnLoad) {
var D=document, scriptNode = D.createElement('script');
if(runOnLoad) scriptNode.addEventListener("load", runOnLoad, false);
scriptNode.type = "text/javascript";
if(text) scriptNode.textContent = text;
if(s_URL) scriptNode.src = s_URL;
if(funcToRun) scriptNode.textContent = '(' + funcToRun.toString() + ')()';
var targ = D.getElementsByTagName('head')[0] || D.body || D.documentElement;
targ.appendChild(scriptNode);
}
addJS_Node (null, null, GM_main);
At first I was going to go with Tampermonkey userscripts,Because I did not know about Fiddler
==================================================================================
Now,lets focus on Fiddler
Before Request:
I want Fiddler to add text at the end of Google Query string.
Someone suggested me to use
static function OnBeforeRequest(oSession: Session) {
if (oSession.uriContains("targetString")) {
var sText = "Enter a string to append to a URL";
oSession.fullUrl = oSession.fullUrl + sText;
}
}
Before Response:
This is where my problem lies
I totally love the HTML response,Now I just want to scrape/hide the word in the search box without changing the search results.How can it be done? Any Ideas?
http://i.stack.imgur.com/4mUSt.jpg
Can you guys please take the above information and fix the problem for me
Thank you
Basing on goal definition above, I believe you can achieve better results with your own free Google custom search engine service. In particular, because you have control over GCSE fine-tuning results, returned by regular Google search.

CryptoJS v3.1.2, sha1.js rollup
In JS I want to calculate the SHA1 of a blob before sending it to the server. On the server I want to calculate the SHA1 of the resulting file and compare it to the SHA1 received from JS. The problem is that the hash generated by CryptoJS.SHA1() is incorrect (always 9844f81e1408f6ecb932137d33bed7cfdcf518a3)
JS Code:
function uploadFileslice (slice) { // slice is a blob
var fileReader = new FileReader()
fileReader.onload = function(event){
var arrayBuffer = event.target.result
var wordArray = CryptoJS.lib.WordArray.create(arrayBuffer)
var sha1crc = CryptoJS.SHA1(wordArray).toString(CryptoJS.enc.Hex)
//etc
requestParams.append('fileslice', slice)
requestParams.append('sha1crc', sha1crc)
//etc
}
fileReader.readAsArrayBuffer(slice)
}
PHP code:
$file_crc = sha1_file($_FILES['fileslice']['tmp_name']);
if ($_REQUEST['sha1crc'] !== $file_crc) {
echo "Invalid CRC: {$_REQUEST['sha1crc']} (expected $file_crc)";
return;
}
Output:
Invalid CRC: 9844f81e1408f6ecb932137d33bed7cfdcf518a3 (expected 3ebe2cd2d8fd8d8f977b6d715f0b1adf5b08b407
I was hoping for something like myHash = CryptoJS.SHA1(blob)
From the info that you've provided I'm not sure exactly how you have things setup but in order for ArrayBuffers to be supported you have to include components/lib-typedarrays-min.js.
There's a discussion about this at https://code.google.com/p/crypto-js/issues/detail?id=67.
Hope this helps!
If you are using modules and import you can:
import Hex from 'crypto-js/enc-hex'
import WordArray from 'crypto-js/lib-typedarrays'
import sha1 from 'crypto-js/sha1'
const hash = sha1(WordArray.create(arrayBuffer)).toString(Hex)
