Flask框架第二篇.Flask中的配置
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()
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()
<!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>

def set_session():
session["key"] = 123
return "200 ok"
@app.route("/get_session")
def get_session():
print(session.get("key"))
return jsonify({"k1":"v1"})
