This chat-server was created for Unix-like systems on Ubuntu 16.0. All the data are stored in database sqlite3, project is written on Golang. To build the project firstly you need to install packages "database/sql", "github.com/golang/gddo/httputil/header", "github.com/mattn/go-sqlite3". Secondly you need to build a sqlite3 driver for linux with commands
set GOOS=linux
go build -v github.com/mattn/go-sqlite3
Choose the right GOOS value according to your operating system. Now it's time to compile and run the project (supposingly you are in the same directory with this project):
go build server.go
./server
Before running the project you need to initialize database and main entities User, Chat, Message by running a file createDB.go (only once).
There are some examples of using the application. Let's add a new user with the command:
curl --header "Content-Type: application/json" \
--request POST \
--data '{"username": "anna"}' \
http://localhost:9000/users/add
Now create a new chat (all users' id in chat exist):
curl --header "Content-Type: application/json" \
--request POST \
--data '{"name": "chat_1", "users": ["1", "2"]}' \
http://localhost:9000/chats/add
Let's send a message:
curl --header "Content-Type: application/json" \
--request POST \
--data '{"chat": "1", "author": "1", "text": "hello"}' \
http://localhost:9000/messages/add
To get the list of all chats of one user sorted by the creation time of the last message in every chat (from the latest to the earliest) write a command:
curl --header "Content-Type: application/json" \
--request POST \
--data '{"user": "2"}' \
http://localhost:9000/chats/get
To get all the messages from one exact chat sorted by the creation time (from the earliest to the latest) use a command:
curl --header "Content-Type: application/json" \
--request POST \
--data '{"chat": "1"}' \
http://localhost:9000/messages/get
