【记录】参考Flask教程去通过视图设计的Restful的API接口

Flask crifan 1205浏览 0评论

先去参考:

使用 Python 和 Flask 设计 RESTful API — Designing a RESTful API with Python and Flask 1.0 documentation

->

The code from my article on building RESTful web services with Python and the Flask microframework. See the article here: http://blog.miguelgrinberg.com/post/designing-a-restful-api-with-python-and-flask · GitHub

-》

Designing a RESTful API using Flask-RESTful – miguelgrinberg.com

-》

REST-tutorial/rest-server-v2.py at master · miguelgrinberg/REST-tutorial · GitHub

Implementing a RESTful Web API with Python & Flask

去折腾。

参考:

[记录]CentOS中安装和使用virtualenv

去创建虚拟环境

➜  ~ mkvirtualenv RunningFast
New python executable in /root/Envs/RunningFast/bin/python
Installing setuptools, pip, wheel…done.
virtualenvwrapper.user_scripts creating /root/Envs/RunningFast/bin/predeactivate
virtualenvwrapper.user_scripts creating /root/Envs/RunningFast/bin/postdeactivate
virtualenvwrapper.user_scripts creating /root/Envs/RunningFast/bin/preactivate
virtualenvwrapper.user_scripts creating /root/Envs/RunningFast/bin/postactivate
virtualenvwrapper.user_scripts creating /root/Envs/RunningFast/bin/get_env_details
(RunningFast) ➜  ~ mkdir RunningFast
(RunningFast) ➜  ~ cd RunningFast 
(RunningFast) ➜  RunningFast ll
total 0
(RunningFast) ➜  RunningFast pwd
/root/RunningFast

参考:

[记录]CentOS服务器中为微信开发安装Flask服务器

去安装Flask

(RunningFast) ➜  RunningFast pip install flask
Collecting flask
  Using cached Flask-0.11.1-py2.py3-none-any.whl
Collecting itsdangerous>=0.21 (from flask)
Collecting Jinja2>=2.4 (from flask)

参考:

[记录]尝试将Nginx请求转到gunicorn运行的Flask

去安装gunicorn

(RunningFast) ➜  RunningFast pip install gunicorn
Collecting gunicorn
  Using cached gunicorn-19.6.0-py2.py3-none-any.whl
Installing collected packages: gunicorn
Successfully installed gunicorn-19.6.0

然后此处打算让Flask运行在本地的21084端口

所以需要去更新nginx的配置

参考:

[已解决]Flask中用gunicorn和Nginx出错:502 Bad Gateway

去看看当前配置:

(RunningFast) ➜  RunningFast cat /etc/nginx/conf.d/default.conf  
server {
    listen       80;
    server_name  localhost;
    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;
        location / {
        proxy_pass         http://127.0.0.1:8080/;
        #proxy_redirect     off;
        proxy_set_header   Host                 $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    $scheme;
    }
    #location / {
    #    root   /usr/share/nginx/html;
    #    index  index.html index.htm;
    #}
    #error_page  404              /404.html;
    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}
    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}
    # deny access to .htaccess files, if Apache’s document root
    # concurs with nginx’s one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

->

怎么感觉好像是:

对于此处的Flask的Restful的api来说:

好像不需要设置nginx的转发?

因为直接访问了api接口了?

去试试

最后解决了:

【已解决】Flask的Python服务外网无法访问

现在已经可以:

启动Flask服务:

gunicorn -w 4 -b 0.0.0.0:21084 run:app &

外网可以访问了:

然后试了试PyCharm中的restful的api测试工具:

【整理】flask restful api 测试工具

另外也去:

【已解决】PyCharm自动上传改动更新后的文件到CentOS服务器上

再去安装:flask-httpauth

(RunningFast) ➜  RunningFast pip install flask-httpauth
