Flask框架第二篇.Flask中的配置

1. 初始化配置

from flask import Flask,render_template,send_file
import os
​
# 1. template_folder="templatess"   模板文件 存放路径(动态)
# 2. static_folder       静态文件存放目录,默认值 static
# 3. static_url_path     静态文件访问路径,默认值 / + static_folder
​
#( 用的少)
# 4. static_host        静态文件的远程存放路径
# 5. host_matching = False,  如果不是特别需要的话,慎用,否则所有的route 都需要host=""的参数
# 6. subdomain_matching = False,  # 理论上来说是用来限制SERVER_NAME子域名的,但是目前还没有感觉出来区别在哪里
app = Flask(__name__,template_folder="templatess",static_folder="img",static_url_path="/static")
​
@app.route("/index")
def index():
    return render_template("/index.html")
​
if __name__ == '__main__':
    app.run()
View Code
import os
from flask import Flask, render_template, send_file
​
app = Flask(__name__,template_folder="templatess",static_folder="img",static_url_path="/static")
​
@app.route("/")
def index():
    return render_template('index.html')
​
if __name__ == '__main__':
    app.run()
View Code
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <h3>hello world!</h3>
    <img src="/static/1.jpg">
</body>
</html>
index.html

2. 实例化配置

from flask import Flask,session,jsonify
​
​
app = Flask(__name__,template_folder="templatess")
#app.debug = True
app.config["DEBUG"] = True
app.secret_key = "*^%$#^&^$##@#&&*HFRRECHJ"
app.session_cookie_name = "I am not session"
app.permanent_session_lifetime = 20    #单位:秒
app.config["JSONIFY_MIMETYPE"] = "Sakura"
​
​
@app.route("/set_session")
def set_session():
    session["key"] = 123
    return "200 ok"
​
@app.route("/get_session")
def get_session():
    print(session.get("key"))
    return jsonify({"k1":"v1"})
​
​
if __name__ == '__main__':
    app.run()
