sqless

An async HTTP server for SQLite, FileStorage and WebPage.

Description

sqless is a Python application that provides web service with local database and local file storage.

Installation

pip install sqless

Quick Start

Running the server

sqless --host 127.0.0.1 --port 12239 --secret your-secret-key

This will create www directory in the current directory, which is used for WebPage. You can access the www/index.html at http://127.0.0.1:12239/index.html

It will also creates db and fs directories in the current directory, when saving data by database API and file storage API.

Using the database API

import requests

# Set up the base URL and authentication
BASE_URL = "http://127.0.0.1:12239"
SECRET = "your-secret-key"
DB_TABLE = "users"

# Insert or update data
r = requests.post(
    f"{BASE_URL}/db/{DB_TABLE}",
    headers={"Authorization": f"Bearer {SECRET}"},
    json={"key": "U001", "name": "Tom", "age": 14}
)

# Query data
r = requests.get(
    f"{BASE_URL}/db/{DB_TABLE}/key = U001",
    headers={"Authorization": f"Bearer {SECRET}"}
)

# Fuzzy query
r = requests.get(
    f"{BASE_URL}/db/{DB_TABLE}/name like %om%?limit=10&page=1",
    headers={"Authorization": f"Bearer {SECRET}"}
)

# Value query
r = requests.get(
    f"{BASE_URL}/db/{DB_TABLE}/age > 10?limit=10&page=1",
    headers={"Authorization": f"Bearer {SECRET}"}
)

# Delete data
r = requests.delete(
    f"{BASE_URL}/db/{DB_TABLE}/key = U001",
    headers={"Authorization": f"Bearer {SECRET}"}
)

DB_TABLE = "users" will read/write records in users table in db/default.sqlite. DB_TABLE = "mall-users" will read/write records in users table in db/mall.sqlite. DB_TABLE = "east-mall-users" will read/write records in users table in db/east/mall.sqlite.

Using the FileStorage API

import requests

# Upload a file to ./fs/example.txt
with open("example.txt", "rb") as f:
    r = requests.post(
        f"{BASE_URL}/fs/example.txt",
        headers={"Authorization": f"Bearer {SECRET}"},
        files={"file": f}
    )

# Check if a file exists
r = requests.get(
    f"{BASE_URL}/fs/example.txt?check=1",
    headers={"Authorization": f"Bearer {SECRET}"}
)

# Download a file
r = requests.get(
    f"{BASE_URL}/fs/example.txt",
    headers={"Authorization": f"Bearer {SECRET}"},
    stream=True
)
with open("downloaded_example.txt", "wb") as f:
    for chunk in r.iter_content(chunk_size=8192):
        f.write(chunk)

Using the Proxy API

import requests
import base64

payload = {
    "method": "POST",
    "url": "https://httpbin.org/post",
    "headers": {
        "User-Agent": "SQLESS-Client/1.0",
        "Authorization": "Bearer mytoken"
    },
    "type": "form",
    "data": {"foo": "bar"},
    "files": [
        {
            "field": "file1",
            "filename": "example.txt",
            "content_type": "text/plain",
            "base64": base64.b64encode(open("example.txt", "rb").read()).decode()
        }
    ]
}

r = requests.post(
    f"{BASE_URL}/xmlhttpRequest",
    headers={"Authorization": f"Bearer {SECRET}"},
    json=payload
)
print(r.json())
