Integration of Tinode in an existing project

[radazul...@gmail.com]

Is there a way to integrate Tinode in an existing website with it's own users database, groups, avatars, names, etc? I really don't understand.

I need something like this:

- user registers on the website and the registration script (php) automatically creates a new user in the messenger.

- user logins to the website and when access the section "Messages" (tinode) he is automatically logged in to the messenger without a need to enter username/password.

- user registration and creating of groups and many other functions are disabled in the messenger and only is possible from the website

- user changes his avatar on the website and new avatar appears in the messenger

- user sends a message to another user from a form on the profile (without opening messenger) and this message automatically goes to Tinode and new contact is automatically added to the recipient in Tinode

- user deleted his profile on the website and the same user is deleted fom Tinode

etc, etc

Can this be done from a php script?

I was thinking that I will be able to create/delete users groups just by inserting/deleting data in Tinode's MySQL database.

I was thinking that I can download Tinode web app and just remove things like user registration, creating of new groups, etc and create/delete users just by inserting/deleting data in Tinode's MySQL database. But then I used Docker to install Tinode and now when I access any of my domains:

https://domain1:6060

https://domain2:6060

appears Tinode messenger's interface, the same as the web app, with all the functions - user registration/groups creation, etc. How do I deactivate it? I want only the web app and mobile messangers but not Tinode's chat accessing address https://domain1:6060 which I can not even edit.

If it's not possible, I just have to forget about Tinode.

Thanks.

You can write your own authenticator which, for example, uses shared cookies for authentication.

You can generate auth tokens and save them to localStore where they can be picked up by Tinode webapp.

 

- user registration and creating of groups and many other functions are disabled in the messenger and only is possible from the website

https://github.com/tinode/chat/tree/master/tn-cli

 

- user changes his avatar on the website and new avatar appears in the messenger

https://github.com/tinode/chat/tree/master/tn-cli

It can be added to https://github.com/tinode/chat/tree/master/server/auth/rest but it would require work. 

 

- user sends a message to another user from a form on the profile (without opening messenger) and this message automatically goes to Tinode and new contact is automatically added to the recipient in Tinode

https://github.com/tinode/chat/tree/master/tn-cli

 

- user deleted his profile on the website and the same user is deleted fom Tinode

https://github.com/tinode/chat/tree/master/server/auth/rest

That's not a good idea.

Thank you for your reply.


I saw tni-cli, however I can not understand how can I use it.

My website is on server A but I am going to run Tinode+Tinode's database on server B. When user creates account on server A, I want to run some script to create the same account on server B (in Tinode).
The same with deleting, updation user information, etc.


As I understand, the only way is to send a CURL request from server A to a PHP script with Python commands located on server B. But in this case I should enable shell_exec() in PHP on server B and this is not a good idea.

Am I missing something?

Given your questions, I suspect you did not read or understand the references I have provided in my original answer. Why don't you read them first and then ask specific questions which would show that you had done your homework?

Thanks.

[radazul...@gmail.com]

Thank you for your reply. Sorry, I didn't read all the documentation, it's clear now.

I have installed tn-cli and  tinode_grpc  but really don't understand how do I perfom actions from server A where website is located to server B where Tinode is running.

Can anyone give me some example?

I need to delete users, create group topics and add subscribe users, send messages as root from user a to user B...

Can I do it by sending a curl request from php? If yes, to which URL?

 My Tinode conf. contains: "grpc_listen": ":16060", however if I try to access: https://domain:16060 I get  ERR_HTTP2_PROTOCOL_ERROR

Here are examples of basic management tasks performed with tn-cli

It's gRPC. You can add another layer in the form of http calls but you don't need to. 

curl issues HTTP requests, tn-cli issues gRPC calls. You can also call gRPC directly from PHP. 

Do this tutorial: https://grpc.io/docs/languages/php/basics/

 

 My Tinode conf. contains: "grpc_listen": ":16060", however if I try to access: https://domain:16060 I get  ERR_HTTP2_PROTOCOL_ERROR  

It's gRPC. You need to use a gRPC client. If your code is in PHP then start here: https://grpc.io/docs/languages/php/quickstart/

[Soy yo]

netstat -ltnp | grep -w ':16060' 

tcp6       0      0 :::16060                :::*                    LISTEN      5793/./tinode

But when I try to run the command line   python tn-cli.py --login-basic=alice:alice123 appears this:

python tn-cli.py --login-basic=alice:alice123

Tinode command line client. Version 1.5.1/0.16.7; gRPC/1.32.0.

Server at 'localhost:16060'

Logging in with login:password alice:alice123

gRPC failed with StatusCode.UNAVAILABLE: failed to connect to all addresses

Shutting down...

[Gene]

It looks like you have some kind of network problem. It works for me:

$ python3 ./tn-cli.py

Tinode command line client. Version 1.5.2/0.16.8; gRPC/1.19.0; Python 3.7.2. 
Server at 'localhost:16060'
Logging in with cookie file
Missing or invalid cookie file '.tn-cli-cookie' [Errno 2] No such file or directory: '.tn-cli-cookie'

<= 201 created
tn>

The only material difference I see is gRPC/1.19.0 vs gRPC/1.32.0.

[Gene]

Upgraded to the latest gRPC, still works fine:

$ python3 ./tn-cli.py
Tinode command line client. Version 1.5.2/0.16.8; gRPC/1.33.1; Python 3.7.2.

Server at 'localhost:16060'

I just installed Tinode on a new server. Debian 10 Buster. No firewall set up, nothing. But still I am getting the same error:

gRPC failed with StatusCode.UNAVAILABLE: failed to connect to all addresses

python tn-cli.py --login-basic=alice:alice123

If I had to guess, your server is probably not listening on localhost:16060. It's listening on something else, like my-host:16060. 

[Soy yo]

lsof -i

[Gene]

Google for it:

https://www.google.com/search?q=grpc+failed+to+connect+to+all+addresses

For example, try this: 

https://github.com/grpc/grpc/issues/9987

This is your installation, so debug it.

[Soy yo]

There were several problems.

1. Nginx running on port 80. Nginx was already running before I installed Tinode and it looked that there are no problems. But I was not able to restart Nginx because of error message saying that another service is listening to port 80. I just changed Nginx port number to 8080.

2. While experimenting I changed  the "listen" value in tinode.conf to "listen": "localhost:6060". It allows to start Tinoe but in my case I was not able to login from the web app (I didn't test the mobile apps) - Connection failed: 503. So, I had to change it back to: "listen": ":6060"

3. I was not able to make grpc calls because I started Tinode with:

./tinode &

If I start Tinode with:

sudo ./tinode &

everything works fine. I guess it's a permission issue of Letsencrypt files or folders. If somedoby knows correct permissions so that it's possible to start Tinode without sudo, please let me know.

4. I was making grcp call without ssl flag as in the ducumentation:

python tn-cli.py --login-basic=alice:alice123 

it didn't work. This works:

python tn-cli.py --host=127.0.0.1:16060 --web-host=127.0.0.1:6060 --ssl --ssl-host=example.domain --login-basic=alice:alice123

More questions on grpc calls.

1) Sending messages as root user

Documentation says:

it allows the root user to send messages on behalf of other users 

Can somebody give me example of grpc call how do I send a messge from user A to user B as a root user C? 

2) Can root user create group topics on behalf of other users and subscribe users to the created group topics?

An example would be appreciated.

Thanks.

You can run multiple web servers behind Nginx. Take a look at the proxy_pass directive. That's how we set up our sandbox.tinode.co and web.tinode.co

You need to reload the app after changing the port on the server.

See how .use command works in tn-cli

https://github.com/tinode/chat/tree/master/tn-cli#local-non-networking 

2) Can root user create group topics on behalf of other users and subscribe users to the created group topics?

An example would be appreciated.

Yes. It works exactly the same way as normal except set on_bahalf_of:

I spent already more than 2 days trying to understand GRPC. There are only a few tutorials that lead to nowhere. I even posted a project on Freelancer, got only 6 bids but looks that all the persons submitted bids without reading the project because later noone wanted to do this job.

I stopped to read tutorials and did the following things. Probably everything is wrong, I don't know.

- Installed php grpc extension

- Generated php classes from Tinode's proto file

I attach a file to this post how my files look like. If it's correct, can someone help me and change the index.php file to show the following things:

- connect and authenticate by Tinode's GRPC server with a secure connection as a root user

- create an user account

- delete an user account

- send a message on behalf of root user A from user B to user C.

- create a group as a root user on behalf of another user.

I am willing to pay for it. If it's needed, please leave a message how can I contact you.

But please, I don't need links to tutorials.

Thanks.

Yes, that's what you are supposed to do.

Why don't you look at python chatbot and tn-cli code? Python is not that different from PHP.

[Soy yo]

I already looked at this example in go. It uses: 

conn, err := grpc.Dial("localhost:6061", grpc.WithInsecure()) 

to establish connection and then sends "hi" message. 

hi := &pbx.ClientHi{}  

I really don't unerstand how do I establish connection from php. What is the alternative of Go's "Dial"?

[Gene]

Why don't you look at the official example https://github.com/grpc/grpc/tree/v1.33.1/examples/php

This is where it defines the connection parameters:

https://github.com/grpc/grpc/blob/v1.33.1/examples/php/route_guide/route_guide_client.php#L26

This is the explanation:

https://grpc.io/docs/languages/php/basics/

[Marc Lewis]

I'm at the exact place you are right now. It looks like you managed to get it working in more recent threads. Can you share any insights in how you got this working? I'm sure once I get the basic connection down that it will all "click" but right now I'm having a hard time finding the missing puzzle pieces.
