I'm used 'olm' version '3.1.4' and 'matrix-js-sdk' version '2.4.6'
Trying use end to end encryption supported in matrix using olm
I'm using the following code snipping:
const cryptoStore = new sdk.MemoryCryptoStore(window.localStorage);
const webStorageSessionStore = new sdk.WebStorageSessionStore(window.localStorage);
var matrixStore = new sdk.MatrixInMemoryStore();
matrixClient = sdk.createClient({
baseUrl: 'SERVER_HOME',
accessToken: token,
userId: 'USER_ID',
store: matrixStore,
sessionStore: webStorageSessionStore,
cryptoStore: cryptoStore,
deviceId: 'DEVICE_ID'});
matrixClient.initCrypto()
.then(() => {
matrixClient.startClient({ initialSyncLimit: 10 });
})
1- I have error with post key/upload API bad request
REQUEST: POST Request URL: https://SERVER_HOME/_matrix/client/r0/keys/upload/DEVICE_ID?access_token=XXXX
RESPONSE: 400 Bad Request {"errcode":"M_UNKNOWN","error":"One time key signed_curve25519:XXXX already exists.

I am currently developing a dapp and I am integrating walletconnect.
I use this code for connecting:
const chainId = ContractService.getPreferredChainId();
const rpc = ContractService.getRpcAddress();
provider = new WalletConnectProvider({
infuraId: undefined,
rpc: {
[chainId]: rpc,
},
});
await provider.enable();
chainId is dynamically chosen based on if the app is in development mode or not. while in development it runs on chain id 97.
RPC is the same story, it just gets the binance smart chain RPC JSON provider.
Connecting works well, but I get the following error:
Any idea on how I can fix this without making an infura account? Or is that required..
I found out what the problem was.
make sure to add a chainId to the object like this:
new WalletConnectProvider({
infuraId: undefined,
rpc: {
1: "https://RPC_URL",
},
chainId: 1
});
Then it should work without issues, you can even omit the infuraId field
I'm a server side developer with rudimentary JS knowhow. I'm tinkering with Agora's audio broadcasting functionality (specifically for the web). For reference, I've been following this: https://docs.agora.io/en/Audio%20Broadcast/start_live_audio_web?platform=Web
I'm attempting to broadcast audio as a host. I have an HTML button which fires a JS function where I:
Initialize a client
Set the role
Join a predefined channel
Publish a local stream
My understanding is that accomplshing the aforementioned will enable me to broadcast audio. When I try this, I end up getting a client join failed DYNAMIC_KEY_EXPIRED error. I'm unable to find documentation regarding how to resolve this. Can you help me resolve this? An illustrative example would be nice.
My JS code is below. Note that I'm using a temp token to test this functionality on localhost.
// rtc object
var rtc = {
client: null,
joined: false,
published: false,
localStream: null,
remoteStreams: [],
params: {}
};
// Options for joining a channel
var option = {
appID: "anAppID",// from 'Project Management' dashboard
channel: "AudioLive",
uid: null,//The user ID should be unique in a channel. If you set the user ID as null or 0, the Agora server assigns a user ID and returns it in the onSuccess callback.
token: "aTempToken"// TEMP Token
}
function createBroadcast(role) {
console.log("entered createBroadcast");
// Create a client
rtc.client = AgoraRTC.createClient({mode: "live", codec: "h264"});
// Initialize the client
rtc.client.init(option.appID, function () {
console.log("init success");
// Note: in a live broadcast, only the host can be heard and seen. You can also call setClientRole() to change the user role after joining a channel.
rtc.client.setClientRole(role);
console.log("role is set");
// Call Client.join in the onSuccess callback of Client.init
rtc.client.join(option.token ? option.token : null, option.channel, option.uid ? +option.uid : null, function (uid) {
console.log("join channel: " + option.channel + " success, uid: " + uid);
rtc.params.uid = uid;
// Call AgoraRTC.createStream to create a stream in the onSuccess callback of Client.join
rtc.localStream = AgoraRTC.createStream({
streamID: rtc.params.uid,
audio: true,
video: false,
screen: false,
})
// Call Stream.init to initialize the stream after 'creating' the stream above
// Initialize the local stream
rtc.localStream.init(function () {
console.log("init local stream success");
// play stream with html element id "local_stream"
rtc.localStream.play("local_stream");
// Call Client.publish in the onSuccess callback of Stream.init to publish the local stream
// Publish the local stream
rtc.client.publish(rtc.localStream, function (err) {
console.log("publish failed");
console.error(err);
})
}, function (err) {
console.error("init local stream failed ", err);
});
}, function(err) {
console.error("client join failed", err)
})
}, (err) => {
console.error(err);
});
}
<div style="background:#f0f3f4;padding:20px">
<button id="broadast" style="height:40px;width:200px" onclick="createBroadcast('host')">Start Live Broadcast</button>
</div>
I've not added the actual values for appID and token in the code above.
Note: Please ask for more information in case you require it.
The error that you are facing is due to the expiry of the token generated for authentication purposes while generating an APP ID. To resolve this you will have to generate a new token as elaborated in the below given links:
Token-expired
renewToken
A token (or a temporary token) expires after a certain period of time. When the SDK notifies the client that the token is about to expire or has expired by the onTokenPrivilegeWillExpire or onTokenPrivilegeDidExpire callbacks, you need to generate a new token and call the renewToken method.
client.on("onTokenPrivilegeWillExpire", function(){
//After requesting a new token
client.renewToken(token);
});
client.on("onTokenPrivilegeDidExpire", function(){
//After requesting a new token
client.renewToken(token);
});
Include the above functions in your javascript code along with the rest of the eventListeners.
Incase your application doesn't require security you can opt to not use a token and generate an App ID without a certificate.
App ID without certificate
Do get back for further support incase the issue remains unresolved.
Trying to embed kin.js in an Ionic App, I can see that the key creation using Keypairs and network initialization is ok
const keys = Keypair.random();
const network = KinNetwork.Production;
However when I try to create the wallet
createWallet(network, keys)
.then(res => {
console.log(res);
}, (err) => {
console.log(err)
});
It keeps retrying but at the end it replies with Error: failed to load account:
I can see the API call is made
https://horizon-kin-ecosystem.kininfrastructure.com/accounts/GANWXV7IHG6YGWVIXJNB56OCBIYI7LYKD34CH556YCDOP5LRC2WDJLTC?c=0.32263221858689695
but the response includes this object
{
“type”: “https://stellar.org/horizon-errors/not_found",
“title”: “Resource Missing”,
“status”: 404,
“detail”: “The resource at the url requested was not found. This is usually occurs for one of two reasons: The url requested is not valid, or no data in our database could be found with the parameters provided.”
}
Any missing parameters I should supply beyond the network and keys
I want to be able to send emails from my local domain without using gmail or other SMTP servers.
I'm currently using SendMail:
const sendmail = require('sendmail') ({
logger: {
debug: console.log,
info: console.info,
warn: console.warn,
error: console.error
},
dkim: {
privateKey: dkimPrivateKey,
keySelector: 'default'
},
});
sendmail({
from: 'foo#mydomain.com',
to: 'mygmail#gmail.com',
subject: 'test sendmail',
html: 'Mail of test sendmail ',
}, function(err, reply) {
console.log(err && err.stack);
console.dir(reply);
});
and this DOES work, BUT when I receive the email in my Gmail account, and I view the message information, Google is marking this as 'security: No encryption'
From what I understand I need to use TLS to create a 'secure' connection. I already have a certificate and keys from LetsEncrypt and my domain is already using HTTPS. How do I encrypt/use TLS my outgoing emails?
Or is there a better package for this? I've tried using NodeMailer and my emails only get added to a 'queue' and never sent. What is the problem?
So my GCM push message works if I use this test link
http://www.androidbegin.com/tutorial/gcm.html
Here's the response
{ "multicast_id":7724943165862866717,
"success":1,
"failure":0,
"canonical_ids":0,
"results":[{"message_id":"0:1418649384921891% 7fd2b314f9fd7ecd"}]}
However if I push using my own service using node push service using the toothlessgear/node-gcm lib
https://github.com/ToothlessGear/node-gcm I get a success message on the server but no msg makes it to the client
{ multicast_id: 5130374164465991000,
success: 1,
failure: 0,
canonical_ids: 0,
results: [ { message_id: '0:1418649238305331%7fd2b3145bca2e79' } ] }
I also tried the same message using pushwoosh and push woosh doesn't work either. How come I'm getting a success message on the server, but no push is received on the client on the latter two services. Is there some sort of ip configuration that I need to do, or some sort of certificate? I've used the same google api server key which is open to all ips on all 3 of these services.
Why does the response show success on the latter but no msg gets received on the client?
Node service server side code
var gcm = require('node-gcm');
// create a message with default values
var message = new gcm.Message();
// or with object values
var message = new gcm.Message({
collapseKey: 'demo',
delayWhileIdle: true,
timeToLive: 3,
data: {
key1: 'message1',
key2: 'message2'
}
});
var sender = new gcm.Sender('insert Google Server API Key here');
var registrationIds = ['regId1'];
/**
* Params: message-literal, registrationIds-array, No. of retries, callback-function
**/
sender.send(message, registrationIds, 4, function (err, result) {
console.log(result);
});
So the pushes were correctly being sent, my issue was with the cordova plugin on the client which requires that the android payload for "message" or "title" be set. The sample php just coincidentally was setting the message property and that's why it worked.
Updating the code to add the following to the data
data: {message:'test'}
works correctly
