Hello I trying shutdown Kodi (raspberry pi) with mobile app (blackberry qml).
But I do not how.
I used this code: (in browser)
"http://[myip]:[myport]/jsonrpc?request={"jsonrpc":"2.0","method":"System.Suspend","id":1}"
I used this code: (in the app)
function sendRequest() {
var xhr = new XMLHttpRequest();
var url = "http://[myip]:[myport]/jsonrpc?request={\"jsonrpc\":\"2.0\",\"method\": \"System.Suspend\",\"id\":1}"
xhr.onreadystatechange = function() {
if (xhr.readyState === XMLHttpRequest.DONE) {
if (xhr.status === 200) {
console.log(xhr.responseText);
textArea.text = xhr.responseText;
}
}
};
xhr.open("GET", url, true); // with "POST" I got the same problem.
xhr.send();
}
I got:
{"error":{"code":-32700,"message":"Parse error."},"id":null,"jsonrpc":"2.0"}
Remote from web browser works fine (http://[myip]:[myport])
Thank you for your answers.
********** Update: 21.10.2020 **********
I'm in progress. But I don't know what to do next.
I found some information why I have an error.
I don't know how to implement in my code.
Can you help me?
Thank you so much.

Here's how to do it.But I can't understand it.
https://retifrav.github.io/blog/2018/09/01/kodi-remote-control-app/
This is my function (on Kodi 17.6 it is working but on Kodi 18 is not working )
function sendRequest() {
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
if (xhr.readyState === XMLHttpRequest.DONE) {
if (xhr.status === 200) {
text.text = xhr.responseText
}
}
};
var url = 'http://<IP:PORT>/jsonrpc?request={"jsonrpc": "2.0", "id": 1, "method": "System.Shutdown"}'
xhr.open("GET", url, true) // when I write "POST" - nothing happens
xhr.send()
}
You should URL encode the json in your url before it's used in the open method. Use encodeURIComponent() to do that. Your browser is changing:
{"jsonrpc":"2.0","method": "System.Suspend","id":1}"
To:
%7B%22jsonrpc%22%3A%222.0%22%2C%22method%22%3A%20%22System.Suspend%22%2C%22id%22%3A1%7D%22
But your code is not.

I am trying to upload an array of images using form data and xhttp.
Client : React Native - Both platforms
Server : Node running on GCP
Images go into s3.
Problem : Images are uploaded into s3. And when i look at my server logs i see the server is sending 200.
But, client is always receiving response code 0.
And also xhttp goes from state 1 -> 4.
We have added CORS on both ends so that might not be an issue.
I have accept and content headers. But, no idea what's going wrong.
Any help is appreciated.
React-Native Client:
upload()
{
let url = "MYAPIGOESHERE"
let uploadBody = new FormData()
let imagesUpload = []
imagesUpload.push({type:'image/jpg',uri:this.state.coverImage[0].uri,name:"cover"})
uploadBody.append('photos',{uri:this.state.coverImage[0].uri, type:'image/jpg', name:"cover"})
uploadBody.append('duration',this.state.duration)
var xhttp = new XMLHttpRequest()
xhttp.onreadystatechange = function() {
console.log(this.readyState+" "+this.statusText)
if (this.readyState === 4) {
alert(this.status)
if (this.status === 200) {
console.log(this.responseText);
} else {
console.log(this);
}
}
if(this.readyState === 3)
{
console.log("Inside 3")
}
if(this.readyState === 2)
{
console.log("Inside 2")
}
};
xhttp.open("POST", url)
xhttp.setRequestHeader('Accept', 'application/json');
xhttp.setRequestHeader('Access-Control-Allow-Origin', '*');
xhttp.responseType = 'json'
xhttp.send(uploadBody)
}
So I'm trying to make a google action using Dialogflow that requires an external API. I've always used jQuery .getJSON() to make API calls, so I had no idea how to do this. After searching this up online, I found a way to do this using vanilla javascript (I also tested the way on my website and it worked fine). The code for that is below:
function loadXMLDoc() {
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == XMLHttpRequest.DONE) {
console.log(xmlhttp.responseText);
}
};
xmlhttp.open("GET", "https://translate.yandex.net/api/v1.5/tr.json/translate?lang=en-es&key=trnsl.1.1.20190105T052356Z.7f8f950adbfaa46e.9bb53211cb35a84da9ce6ef4b30649c6119514a4&text=eat", true);
xmlhttp.send();
}
The code worked fine on my website, but as soon as I added it to the Dialogflow, it would give me the error
XMLHttpRequest is not defined
Obviously that happened because I never defined it (using var), except it worked without me doing anything. So then, I tried adding this line
var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
to the code, and it stopped giving me the error (because I defined XMLHttpRequest). But then, my code wouldn't work.
TL;DR: How can I make an external API call using Dialogflow fulfillment?
You can use https. But make sure that you upgrade to Blaze Pay(or any other plans) to make external API calls, else you will receive an error such as
Error:
Billing account not configured. External network is not accessible and quotas are severely limited. Configure billing account to remove these restrictions.
Code to make external api call,
// See https://github.com/dialogflow/dialogflow-fulfillment-nodejs
// for Dialogflow fulfillment library docs, samples, and to report issues
"use strict";
const functions = require("firebase-functions");
const { WebhookClient } = require("dialogflow-fulfillment");
const { Card, Suggestion } = require("dialogflow-fulfillment");
const https = require("https");
process.env.DEBUG = "dialogflow:debug"; // enables lib debugging statements
exports.dialogflowFirebaseFulfillment = functions.https.onRequest(
(request, response) => {
const agent = new WebhookClient({ request, response });
console.log(
"Dialogflow Request headers: " + JSON.stringify(request.headers)
);
console.log("Dialogflow Request body: " + JSON.stringify(request.body));
function getWeather() {
return weatherAPI()
.then(chat => {
agent.add(chat);
})
.catch(() => {
agent.add(`I'm sorry.`);
});
}
function weatherAPI() {
const url =
"https://samples.openweathermap.org/data/2.5/weather?q=London,uk&appid=b6907d289e10d714a6e88b30761fae22";
return new Promise((resolve, reject) => {
https.get(url, function(resp) {
var json = "";
resp.on("data", function(chunk) {
console.log("received JSON response: " + chunk);
json += chunk;
});
resp.on("end", function() {
let jsonData = JSON.parse(json);
let chat = "The weather is " + jsonData.weather[0].description;
resolve(chat);
});
});
});
}
function welcome(agent) {
agent.add(`Welcome to my agent!`);
}
function fallback(agent) {
agent.add(`I didn't understand`);
agent.add(`I'm sorry, can you try again?`);
}
let intentMap = new Map();
intentMap.set("Default Welcome Intent", welcome);
intentMap.set("Default Fallback Intent", fallback);
intentMap.set("Weather Intent", getWeather);
agent.handleRequest(intentMap);
}
);
This article is a diamond! It really helped to clarify what's going on and what's required in Dialogflow fullfilments.
A small suggestion is to gracefully catch the error in the connection to the webservice:
function weatherAPI() {
const url = "https://samples.openweathermap.org/data/2.5/weather?q=London,uk&appid=b6907d289e10d714a6e88b30761fae22";
return new Promise((resolve, reject) => {
https.get(url, function(resp) {
var json = "";
resp.on("data", function(chunk) {
console.log("received JSON response: " + chunk);
json += chunk;
});
resp.on("end", function() {
let jsonData = JSON.parse(json);
let chat = "The weather is " + jsonData.weather[0].description;
resolve(chat);
});
}).on("error", (err) => {
reject("Error: " + err.message);
});
});
}
Trying to load JSON file with Safari Extension.
var xhr = new XMLHttpRequest();
xhr.open("GET", safari.extension.baseURI +'js/data.json', true);
It gives an error "Cross origin requests are only supported for HTTP."
For example it is possible with Chrome Extenison
var xhr = new XMLHttpRequest();
xhr.open("GET", chrome.extension.getURL('/js/data.json'), true);
There you need to specify it in manifest
"web_accessible_resources": ["/js/data.json"]
Is there a similar way in Safari?
EDIT
Found a solution
It is possible through Global page
global.html
function handleMessage(event) {
if (event.name === "requestParagraphs") {
var xhr = new XMLHttpRequest();
xhr.open("GET", safari.extension.baseURI + 'js/data.json', true);
xhr.onreadystatechange = function () {
if (xhr.readyState == 4) {
var articlesJSON = JSON.parse(xhr.responseText);
event.target.page.dispatchMessage('paragraphs', articlesJSON);
}
};
xhr.send();
}
}
safari.application.addEventListener("message", handleMessage, false);
injected.js
function handleMessage(msgEvent) {
var messageName = msgEvent.name;
var messageData = msgEvent.message;
if (messageName === "paragraphs") {
// ...
}
}
safari.self.addEventListener("message", handleMessage, false); // Listen response
safari.self.tab.dispatchMessage('requestParagraphs'); // Call global page
I'm creating an extenstion for google chrome that will perform checking if a stream on twitch.tv is online and will notify the user evey X minutes, I got that covered. What I'm looking for is a JScirpt code that will recognize if user is already on the streamers channel and will stop notifying him.
var username="$user";
setInterval(check,300000);
function check()
{
request("https://api.twitch.tv/kraken/streams/" + username, function() {
var json = JSON.parse(this.response);
if (json.stream == null)
{
chrome.browserAction.setIcon({ path: "offline.png" });
}
else
{
notify();
}
});
return 1;
}
function notify(){
var opt = {type: "basic",title: username + " is streaming!",message: "Click to join!",iconUrl: "start.png"};
chrome.notifications.create("", opt, function(notificationId)
{
setTimeout(function()
{
chrome.notifications.clear(notificationId, function(wasCleared) { console.log(wasCleared); });
}, 3000);
});
chrome.browserAction.setIcon({path:"online.png" });
}
chrome.browserAction.onClicked.addListener(function () {
chrome.tabs.create({ url: "http://www.twitch.tv/"+username });
});
function request(url, func, post)
{
var xhr = new XMLHttpRequest();
xhr.onload = func;
xhr.open(post == undefined ? 'GET' : 'POST', url, true);
xhr.send(post || '');
return 1;
}
check();
Use window.location.href to get the complete URL.
Use window.location.pathname to get URL leaving the host.

I am developing a chrome extension and I have an iframe which I use in my extension. This is what I do with my iframe
"When I drag and drop a image to my iframe I handle the drop event in one of the content scripts and pass that function call my extension code. There I create a xmlhttprequest object and then send the URL of the image to a php file in my server."
This is what is happening. I get a readyState of "4" but there is no POST request going out of my browser. I checked with the "NETWORK" tab in the browser but there is no POST request going out of the browser (I have listed my site in the permissions section of the manifest file).
This is my code --.>
JScript.js(One of the content scripts )
drop: function(event, ui) {
var imgurl=$(ui.draggable).attr('src');
imgurl="IMGURL="+imgurl;
_post("www.somedomain.come/testing.php",imgurl,function(result){ alert("success")});
}
This is my proxy in the same content script-->
_post = function(url, data, callback)
{
console.log("sending post");
chrome.extension.sendRequest({
msgType:'post',
data: data,
url:url
}, function(response){
alert(response);
});
}
This my OnRequest function handler in background.html -->
chrome.extension.onRequest.addListener(function(request, sender, sendResponse){
if (request.msgType === 'post') {
alert("Now in OnRequest function");
// console.log("Now in Onrequest Function");
alert("Url: "+request.url + "\n Data : "+ request.data);
ajaxcallingfunction(request);
alert("completed the ajax call");
sendResponse("success");
}
});
var ajaxcallingfunction = function(request){
var xhr = new XMLHttpRequest();
xhr.open("POST",request.url, false);
xhr.onreadystatechange = function(){
alert(xhr.readyState);
if (xhr.readyState == 4) {
alert(xhr.readyState);
}
}
xhr.send(request.data);
alert("after xhr call");
};
You have http:// in front of your url, right?
xhr.readyState doesn't tell much, it just means that it is done. Check out what's inside xhr.status, it would contain error code. If everything is ok it should be 200:
xhr.onreadystatechange = function(){
if (xhr.readyState == 4) {
alert(xhr.status);
}
}
