【已解决】部署测评系统Flask后台到在线服务器

Flask crifan 237浏览 0评论
折腾:
【记录】用Flask实现测评系统的后端
期间,需要把现有的Flask代码,先部署到在线服务器中,
以及确保小程序端能调用和访问
->意味着要支持https
-》需要更新nginx配置,支持https的另外一个接口。
本地去安装额外的库:

中间lock太长时间,中断了,去看看,已安装numpy,即可。
先去部署代码,本来想用fabfile的,考虑到git更能支持pull去同步,所以改用git吧

不过运行服务器代码之前,先去确认此处的
supervisor的配置
以及 MongoDB能否访问数据:确认了,在线是有数据了:
另外,对于此处Flask后台所依赖的Evaluation的类,虽然更新了:
但是竟然路径都是相对路径,估计合并会有问题。所以暂时放弃,抽空再去试试。
现用自己的模拟的。
那再去弄supervisor的配置:
【已解决】部署Flask时运行supervisorctl出错:unix:///var/run/supervisor/supervisor.sock no such file
再去设置阿里云安全组,添加允许端口访问:
然后此处可以访问api了:
http://xxx:34800/evaluation?eval_id=5c1aff69bfaa448d0945cb1c&action=nextQuestion
然后接着去弄https的事情。
{{evalation_host}}/evaluation?eval_id=5c1cbcb8dc5486203c51ab11&action=nextQuestion
返回:

                    ]
                }
            ]
        },
        "skipAllowed": true
    },
    "message": "Get next question ok"
}
接着去访问音频和图片,也都可以正常下载的:
http://xxx:34800/audio/5c1c9cb312758830e5481f3e/3569.mp3
http://xxx:34800/image/5c1c9cbc12758830e5482666/look.png
接着就是去弄https,使得小程序
【已解决】CentOS更新nginx配置使得小程序能访问测评系统的Flask后台接口
那再去postman中,添加新的环境变量https的,也可以访问接口了:
再去小程序中换成最新https接口,继续去:
