1. Flask
服务器端代码 (使用 Flask)
python
from flask import Flask, jsonify, request
from flask_compress import Compress
import logging
app = Flask(__name__)
Compress(app) # 启用 gzip 压缩
# 配置日志
logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)
@app.route('/data', methods=['GET'])
def get_data():
try:
# 处理请求参数
count = int(request.args.get('count', 100))
# 返回一些示例 JSON 数据
data = {
'message': 'Hello, this is compressed data!',
'numbers': list(range(count))
}
return jsonify(data)
except Exception as e:
logger.error(f"Error occurred: {e}")
return jsonify({'error': 'Internal Server Error'}), 500
@app.errorhandler(404)
def page_not_found(e):
return jsonify({'error': 'Not Found'}), 404
if __name__ == '__main__':
app.run(debug=True)客户端代码 (接收并解压 gzip 响应)
python
import requests
import gzip
import json
from io import BytesIO
def fetch_data(url):
try:
# 发送请求到服务器端
response = requests.get(url)
# 检查响应头，确认数据是否被 gzip 压缩
if response.headers.get('Content-Encoding') == 'gzip':
# 使用 gzip 解压响应内容
compressed_content = BytesIO(response.content)
with gzip.GzipFile(fileobj=compressed_content, mode='rb') as f:
decompressed_data = f.read()
# 解码解压后的数据
data = json.loads(decompressed_data.decode('utf-8'))
return data
else:
return response.json()
except requests.RequestException as e:
print(f"HTTP request failed: {e}")
return None
except json.JSONDecodeError as e:
print(f"Failed to decode JSON: {e}")
return None
except Exception as e:
print(f"An error occurred: {e}")
return None
if __name__ == '__main__':
url = 'http://127.0.0.1:5000/data?count=50'
data = fetch_data(url)
if data:
print(data)
else:
print("Failed to fetch data.")2. FastAPI
服务器端代码 (使用 FastAPI)
python
pip install fastapi uvicorn fastapi-compress
python
from fastapi import FastAPI, Request, HTTPException
from fastapi.responses import JSONResponse
from fastapi_compress import Compress
import logging
app = FastAPI()
compressor = Compress()
compressor.init_app(app)
# 配置日志
logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)
@app.get("/data")
async def get_data(count: int = 100):
try:
# 返回一些示例 JSON 数据
data = {
'message': 'Hello, this is compressed data!',
'numbers': list(range(count))
}
return JSONResponse(content=data)
except Exception as e:
logger.error(f"Error occurred: {e}")
raise HTTPException(status_code=500, detail="Internal Server Error")
@app.exception_handler(404)
async def not_found_handler(request: Request, exc: HTTPException):
return JSONResponse(status_code=404, content={'error': 'Not Found'})
if __name__ == '__main__':
import uvicorn
uvicorn.run(app, host="127.0.0.1", port=8000, log_level="info")客户端代码 (接收并解压 gzip 响应)
python
