docker nginx-lua发送post json 请求

环境准备 dockerfile

from fabiocicerchia/nginx-lua:1.25.3-ubuntu22.04
run apt-get -qq update && apt-get -qq install luarocks 
run luarocks install lua-cjson
run luarocks install lua-iconv
run luarocks install lua-resty-http

后台代理服务准备（python）

from flask import Flask, jsonify, request
import jsonapp = Flask(__name__)
app.config['JSON_AS_ASCII'] = False@app.route('/test', methods=['POST', 'GET','OPTIONS'])
def hello():request_data = request.get_json()print("Request data:", json.dumps(request_data, ensure_ascii=False, indent=4))data = {'message': '你好'}return jsonify(data)if __name__ == '__main__':app.run(host='0.0.0.0', port=8080)
