DazhouBus-Server

达州实时公交 微信小程序 服务端，客户端请看 DazhouBus-Client

获取最新主页数据

下载源码后直接运行 GetIndexData.py

python GetIndexData.py

信息就会打印在控制台，直接复制粘贴到 DazhouBus-Client/pages/index/index.js#L7 即可。这里手动排序了一下，把K线全都置顶了，其他线路就由从小到大的顺序排列。

搭建服务端

依赖安装

Python 3

pip install flask flask_restful requests gunicorn

运行

SSL证书推荐使用 acme.sh 强烈推荐使用 DNS API

gunicorn --certfile=server.crt --keyfile=server.key --bind 127.0.0.1:443 wsgi:app

终端打印出类似以下信息说明运行成功

[2019-07-21 15:33:25 +0800] [21699] [INFO] Starting gunicorn 19.9.0
[2019-07-21 15:33:25 +0800] [21699] [INFO] Listening at: https://127.0.0.1:443 (21699)
[2019-07-21 15:33:25 +0800] [21699] [INFO] Using worker: sync
[2019-07-21 15:33:25 +0800] [21702] [INFO] Booting worker with pid: 21702

Linux 下你需要使用类似 screen 之类的命令让它保持在后台运行

Nginx

如果你使用一台单独的 WEB 服务器来提供服务，以上就是最简的部署方法。如果你现在正在使用 Nginx ，那么你可以参考以下配置文件通过 Nginx 代理将请求转发到 flask 。

server {
    listen       443 ssl http2;
    server_name  api.example.com;
    server_tokens        off;

    #access_log  /tmp/api.log;

    ssl_certificate     /etc/nginx/ssl/example.com.ecc.crt;
    ssl_certificate_key /etc/nginx/ssl/example.com.ecc.key;

    # openssl dhparam -out dhparams.pem 2048
    # https://weakdh.org/sysadmin.html
    ssl_dhparam         /etc/nginx/ssl/dhparam.pem;

    ssl_ciphers                EECDH+CHACHA20:EECDH+CHACHA20-draft:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5;

    ssl_prefer_server_ciphers  on;

    ssl_protocols              TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
    ssl_session_cache          shared:SSL:50m;
    ssl_session_timeout        1d;

    location / {
        root   /etc/nginx/html;
        index  index.html;
    }

    location /bus {
        proxy_pass http://127.0.0.1:8866;
        proxy_redirect     off;
        proxy_set_header   Host                 $http_host;
        proxy_set_header   X-Real-IP            $remote_addr;
        proxy_set_header   X-Forwarded-For      $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto    $scheme;
    }

}

server {
    server_name  api.example.com;
    server_tokens     off;

    #access_log  logs/host.access.log;

    if ($request_method !~ ^(GET|HEAD|POST)$ ) {
        return        444;
    }

    location / {
        rewrite       ^/(.*)$ https://api.example.com/$1 permanent;
    }
}
