I have implemented 1-1 chat in QuickBlox Chat and sending some custom data via custom parameters. Is it possible to filter the chat messages based on these custom parameters while fetching the records?
You can not get filter base messages, but you can get filter base dialogs.
look at here :
var filters = {"sort_desc": "last_message_date_sent"} ;
QB.chat.dialog.list(filters, function(err, resDialogs) {
if (err) {
console.log(err);
} else {
}
});
Hope this will help you.

I've created a private messaging app where users login and can view their private messages. The problem that I am having is that is only shows the message list of one logged in user at a time. So let's say User A is logged in, it will show the chat list of user A. But then User B logs in, then both User A and User B will see the chat list of User B.
This is my server side call to fetch chats by user id:
Im using express for the backend
io.on('connection', socket => {
socket.on('findAllChatsByUserId', (userId) => {
socket.userId = userId
socket.join(socket.userId)
ChatModel.aggregate([{$match: {$or:[{senderId: userId},{receiver: userId}]}}, {$group: {_id: '$chatId', 'data': {$last: '$$ROOT'}}}]).exec(function(error, data) {
if (error) {
return error
} else {
data.sort(function (a, b) {
return b.data.date - a.data.date;
});
io.to(socket.userId).emit('findAllChatsByUserId', data);
}
})
})
});
And on the client side I do:
I am using VueJs on the FE
mounted () {
this.loading = true
this.socket.emit('findAllChatsByUserId', this.getUserId) // this calls the socket to get the chats for the given user Id
this.loading = false
},
I tried creating rooms by userId to make sure that only the data for a given user ID is passed in but it seems like only one user can use the socket at a time. I thought the rooms would solve this issue for me. Do I have to create a separate socket for each user? If so, how do I do that? I've followed the socket.io private messaging tutorial but they use 2 users talking to each other to explain the problem.
So I ended up solving this by doing:
io.to(socket.id).emit('findAllChatsByUserId', data);
instead of:
io.to(socket.userId).emit('findAllChatsByUserId', data);
So you use the "to" attribute to make sure the data you're sending is going to a particular socket, and you can find your specific socket by just calling socket.id (you don't have to set this, it gets set on its own. And the data will get emitted to whomever is on that specific socket.
im new on Angular and have a question.
I need to call 2 API Rest, on second API i need result of first API.
I have this code:
ngOnInit() {
this.Jarwis.getmyinfo()
.subscribe(
// data => console.log(data),
data => this.Getmyinfo = data,
error => console.log(error),
);
this.Jarwis.showazienda(id_azienda).subscribe(
// data => console.log(data),
data => this.Showazienda = data,
error => console.log(error),
);
}
This is a call to API rest in Jarwis:
getmyinfo(): Observable {
return this.http.get(${this.baseUrl}/me);
}
showazienda(data): Observable {
return this.http.get(${this.baseUrl}/showazienda/ + data);
}
getmyinfo is first HTTP REQUEST and where i need to get id_azienda for second HTTP REQUEST (showazienda)
I think need map result of first http request in json and get result of id_azienda but im not able to do it.
If i set 1 in the parameters of showazienda im able to get and show info of API.
For observables, you use the ".flatMap" to chain multiple async actions together (this is very similar to the promises ".then"). The flatMap allows you to used to chain multiple async requests together and have them execute one by one in order.
Here is a good explanation of flatMap.
So for your example, you would do something like this:
ngOnInit() {
this.Jarwis.getmyinfo()
.flatMap(
(data) => {
this.Getmyinfo = data;
// get id_azienda from data
return this.Jarwis.showazienda(id_azienda);
}
).subscribe(
// data => console.log(data),
data => this.Showazienda = data,
error => console.log(error),
);
}
This example code will first send the "getmyinfo()" request. Once the response is received the ".flatMap" will be called with the data received from "getmyinfo()". You can then used this data to get the "id_azienda". Then you can make the second request to "showazienda". The observable returned from "showazienda()" needs to be returned in the flatMap. Then you subscribe to the modified observable and the data you receive will be the result from the "showazienda()" request.
I'm trying to write an example app in wit.ai. I followed the quickstart app using node.js client that is shown at https://wit.ai/docs/quickstart.
The example shown there has only one custom action. But when I try to add a new story and a new action, I see that the context is being shared between the stories. This is causing wrong behaviour(a custom action from another story is being executed).
I cannot find any example with multiple custom actions and stories. Are there any node.js or python examples other than the ones from wit.ai websites?
You need to create a context for each session, and this is a quick example (from https://github.com/wit-ai/node-wit/blob/master/examples/messenger.js):
const findOrCreateSession = (fbid) => {
let sessionId;
// Let's see if we already have a session for the user fbid
Object.keys(sessions).forEach(k => {
if (sessions[k].fbid === fbid) {
// Yep, got it!
sessionId = k;
}
});
if (!sessionId) {
// No session found for user fbid, let's create a new one
sessionId = new Date().toISOString();
sessions[sessionId] = {
fbid: fbid,
context: { // New context per session id.
_fbid_: fbid
}
}; // set context, _fid_
}
return sessionId;
};
You can find a working example at https://github.com/hunkim/Wit-Facebook.
I suppose wit engine don't store context on their side.
You 'merge' function must merge entities in different ways, depending on your app logic.
But if you story is completed, you need to clear context for next stories.
I added a built-in function clear-context and call this function from wit as action.
Check out my example.
It's not an official api, but you can understand how wit http api works.
I'm trying to interface with the Tumblr API to pull a list of followers. I'm brand new the whole OAuth thing, so I was trying to model my calls off the demos at https://adodson.com/hello.js/demos/tumblr.html . Unfortunately, the example they give only requires the API key for identification (https://www.tumblr.com/docs/en/api/v2#posts) where as getting the followers needs a signed OAuth request (https://www.tumblr.com/docs/en/api/v2#followers).
The call I'm using is:
function getFollowers(blog){
hello('tumblr').api('blog/'+blog+'/followers/').then(function(r){
console.log("r", r);
//Bellow here not really relevant
var a = r.data.map(function(item){
return "<h2>"+item.title+"</h2>"+item.body_abstract;
});
document.getElementById('blogs').innerHTML = a.join('');
});
}
This generates the request url from the proxy:
https://auth-server.herokuapp.com/proxy?path=https%3A%2F%2Fapi.tumblr.com%2Fv2%2Fblog%2Fnmlapp.tumblr.com%2Ffollowers%2F%3Fapi_key%3DREDACTED08u%26callback%3D_hellojs_9kvqxi31&access_token=&then=redirect&method=get&suppress_response_codes=truee
and Tumblr's API returns
_hellojs_9kvqxi31({"meta":{"status":401,"msg":"Not Authorized"},"response":[]});
I can see that the login call has all of the OAuth info in the Query String Parameters field, and the one I'm trying to make does not, but I'm not sure what the right way to include that through helloJS is.
Got it, the function had to be wrapped in the login method. This was shown in the other example, but the way that it called parameters from the api object had me confused.
function doTheThing(network){
hello( network ).login({force:false}).then( function(r){
hello('tumblr').api('followers').then(function(r){
console.log("r", r);
var a = r.data.map(function(item){
return "<h2>"+item.title+"</h2>"+item.body_abstract;
});
document.getElementById('blogs').innerHTML = a.join('');
});
});
}
//...
tumblr:{
get: {
//...
//This next part needs to be generated dynamically, but you get the idea
'followers': 'blog/BLOGNAME.tumblr.com/followers',
}
callback(p.path);
}
},
post: {
//...
'followers': function(p, callback) {
p.path = 'followers';
query(p, callback);
}
},
I am using Meteor and the Twitter API for a project. I want to get information on a user from Twitter. I wrote a function that for example returns only the location of a user from Twitter. I believe this is the proper way to do a request on Meteor. Here it is :
Meteor.methods({getTwitterLocation: function (username) {
Meteor.http.get("https://api.twitter.com/1/users/show.json?screen_name="+ username +"&include_entities=true", function(error, result) {
if (result.statusCode === 200) {
var respJson = JSON.parse(result.content);
console.log(respJson.location);
console.log("location works");
return (respJson.location)
}else {
return ( "Unknown user ")
}
});
}});
Now this function will log what's in the console on my Git Bash. I get someones Location by doing a Meteor.call. But I want to post what that function returns on a page. In my case, I want to post in on a user's profile. This doesn't work. But the console.log(respJson.location) returns the location in my Git Bash but it won't display anything on the profile page. This is what I did on my profile page:
profile.js :
Template.profile.getLocation= function(){
return Meteor.call("getTwitterLocation","BillGates");
}
profile.html :
<template name="profile">
from {{getLocation}}
</template>
With that I get "Seattle, WA" and " "location works" on my Git Bash but nothing on the profile page. If anyone knows what I can do, that'd be really appreciated. Thanks.
Firstly when data is returned from the server you need to use a synchronous call, as the callback will return the data when the server already thinks the meteor method has completed. (the callback will be fired at a later time, when the data is returned from the server, by which time the meteor client would have already got a response)
var result = Meteor.http.get("https://api.twitter.com/1/users/show.json?screen_name="+ username +"&include_entities=true");
if (result.statusCode === 200) {
var respJson = JSON.parse(result.content);
console.log(respJson.location);
console.log("location works");
return (respJson.location)
}else {
return ( "Unknown user ")
}
The second is you need to use a Session hash to return the data from the template. This is because it will take time to get the response and the getLocation would expect an instant result (without a callback). At the moment client side javascript can't use synchronous api calls like on the server.
Template.profile.getLocation= function(){
return Session.get("twitterlocation");
}
Use the template created event to fire the meteor call:
Template.profile.created = function() {
Meteor.call("getTwitterLocation","BillGates", function(err,result) {
if(result && !err) {
Session.set("twitterlocation", result);
}
else
{
Session.set("twitterlocation", "Error");
}
});
});
Update:
Twitter has since updated its API to 1.1 a few modifications are required:
You now need to swap over to the 1.1 api by using 1.1 instead of 1. In addition you need to OAuth your requests. See https://dev.twitter.com/docs/auth/authorizing-request. Below contains sample data but you need to get proper keys
var authkey = "OAuth oauth_consumer_key="xvz1evFS4wEEPTGEFPHBog",
oauth_nonce="kYjzVBB8Y0ZFabxSWbWovY3uYSQ2pTgmZeNu2VS4cg",
oauth_signature="tnnArxj06cWHq44gCs1OSKk%2FjLY%3D",
oauth_signature_method="HMAC-SHA1",
oauth_timestamp=""+(new Date().getTime()/1000).toFixed(0)+"",
oauth_token="370773112-GmHxMAgYyLbNEtIKZeRNFsMKPR9EyMZeS9weJAEb",
oauth_version="1.0"";
Be sure to remove the newlines, I've wrapped it to make it easy to read.
var result = Meteor.http.get("https://api.twitter.com/1.1/users/show.json?screen_name="+ username +"&include_entities=true",{headers:{Authorization : authkey});
If you find this a bit troublesome it might be easier to just use a package like https://github.com/Sewdn/meteor-twitter-api via meteorite to OAuth your requests for you.
