六、请求与响应
1、常用的请求信息
1 @app.route("/home") 2 def home(): 3 from flask import request 4 # 常用请求信息 5 print(request.method) 6 print(request.args) 7 print(request.form) 8 print(request.files) 9 print(request.cookies) 10 print(request.headers) 11 print(request.values) 12 print(request.data) 13 print(request.path) 14 print(request.full_path) 15 print(request.url) 16 print(request.base_url) 17 print(request.url_root) 18 print(request.host) 19 print(request.host_url) 20 print(request.script_root) 21 return "Hello, home!"
2、常用的构造响应的方式（响应编辑Cookie，请求获取Cookie）
1 @app.route("/") 2 def index(): 3 # 响应的几种形式 4 # 返回字符串 5 # return "Hello" 6 # 返回一个int，根据报错信息得知 7 # string, dict, tuple, Response instance, or WSGI callable, but it was a int 8 # The tuple must have the form (body, status, headers), (body, status), or (body, headers). 9 # return (1 , 2, 3, 4) 10 # 返回一个字典，必须是可序列化对象 11 # return {"func": [1, 2, 3]} 12 # 渲染模板 13 # from flask import render_template 14 # data = {} 15 # return render_template("home.html", **data) 16 # 重定向 17 # from flask import redirect 18 # return redirect("/home") 19 20 # 构造一个响应 21 response = make_response("Hello World") 22 response.headers["token"] = "awdadjdkajdaadkjadjadja" 23 response.set_cookie("k", "v") 24 response.delete_cookie("session") 25 return response
