In order to test the client side connectivity with our Openfire XMPP server, the following test script (nodejs) was initially tested, which ran successfully.
async function connectX() {
try {
const keyPair = await XmppUser.generateKeys()
XmppUser.connect(username, password, keyPairs).then(
async user => {
user.getFriends().then(friends => {
console.log("List of Friends: ");
console.log(friends);
user.getChatHistory().then(history => {
console.log("Chat History: ")
console.log(history);
user.closeConnection();
}).catch(e => console.log(e));
}).catch(e => console.log(e));
}
).catch(e => console.log(e));
} catch(e) {
console.log(e)
}
}
connectX()
Output:
List of Friends:
[ '[email protected]', '[email protected]' ]
Chat History:
{ messages:
[ { date: 2020-08-11T12:18:34.314Z,
from: '[email protected]',
to: '[email protected]',
message: 'Hello! Received.',
id: 'D255Q-132' }
] }
lastId: '1',
firstId: '1',
count: '1' }
However, when I run the script in an ionic angular app using the same ChatService class it leads me to the following CORS error.
Access to fetch at 'https://chat.company.io/.well-known/host-meta' from origin 'http://localhost:8100' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
For information, https://chat.company.io/.well-known/host-meta exists and has the following content:
<?xml version='1.0' encoding='utf-8'?>
<XRD xmlns='http://docs.oasis-open.org/ns/xri/xrd-1.0'>
<Link rel="urn:xmpp:alt-connections:httppoll"
href="https://chat.company.io:443" />
</XRD>
The backend infrastructure includes an Nginx server and the chat server runs behind it with the following open ports: 443, 7070, 5222, 5223.
Please help in figuring out what the issue might be.
