Quick Tutorial

Using Python + Requests

    >>> import requests
    >>> url = "http://localhost:8500/bfs/token"
    >>> data = {"username":"user","password":"password"}
    >>> r = requests.post(url, data=data)
    >>> j = r.json()
    >>> print j["status"]
    ok
    >>> token = j["data"]
    >>> cmd = 'server.newdb "test"; server.listdb;'  # issue two commands
    >>> url = "http://localhost:8500/bfs/query"
    >>> data = {"token":token,"query":cmd}
    >>> r = requests.post(url, data=data)
    >>> j = r.json()
    >>> print j["status"]
    ok
    >>> print j["data"][-1]  # get last result
    [u'test']

Using Bytengine Shell bshell

Login:

    bshell run -u=user -p=password

Enter commands:

    bql> server.newdb "test"; server.listdb;
    {
      "data": [
        true,
        [
          "test"
        ]
      ],
      "status": "ok"
    }
    bql> \s lastresult().status
    ok
