一、flask最小运行示例
python
from flask import Flask
app = Flask(__name__)
@app.route("/")
def hello():
return "Hello, Flask!\n"
if __name__ == "__main__":
app.run(host="0.0.0.0", port=7777, debug=True)运行之后，另外开启终端，执行以下命令，可顺利看到结果
bash
curl http://0.0.0.0:7777二、uwsgi+flask最小运行示例
python
from flask import Flask
app = Flask(__name__)
@app.route("/")
def hello():
return "hello flask+uwsgi\n"uwsgi.ini
bash
[uwsgi]
http = :7777
chdir = .
wsgi-file = test.py
callable = app
master = true
processes = 1
threads = 1
vacuum = true
die-on-term = true
logto = uwsgi.log以下命令开启uwsgi服务
bash
uwsgi --ini uwsgi.ini运行之后，另外开启终端，执行http请求
bash
curl http://0.0.0.0:7777/三、复杂案例示例
python
