https on nginx and python flask

建立 python flask 的網頁伺服器
$ cat server.py
@app.route('/api/PostTime', methods=['POST'])
def post_time():
    print(request.headers)
    print(request.json)
    result = '\n'.join([request.json['updDate'],
            request.json['camera']])
    print(result)
    return str(result)

if __name__ == "__main__":
    app.run(host="0.0.0.0", port="5000", debug=True,
            # 下兩行可以啟動 https
            #ssl_context=("/home/user1/Data/webapi/openssl/web1/server.crt",
            #    "/home/user1/Data/webapi/openssl/web1/server.key")
            )

$ python3 server.py

$ cat PostTime.py

import requests

import os

data = {

    'updDate': '2019-01-02T15:10:11',

    'camera': 'A001',

response = requests.post(url=url,

        headers=headers,

        #verify=False,

        json=data)

if response.ok:

    print("PostTime ok")

    print(response.status_code)

    print(response.text)

    print(response.text)

$ python3 PostTime.py

# cat /etc/nginx/sites-available/config

        listen [::]:80 default_server;

        index index.html index.htm index.nginx-debian.html;

        server_name _;

        location ^~ /api/ {
                # 當 https 由 nginx 管控，python flask 就要走一般的 http

                proxy_pass http://127.0.0.1:5000;

                proxy_set_header Host $host;

        }
        # 設定上傳限制
        client_max_body_size 10M;

}

重新啟動 nginx

# sudo nginx -s reload
