Flask框架：视图

Posted 2021-01-25 bad-robot

1、视图中请求request的属性

request.method
request.args
request.form
request.values
request.cookies
request.headers
request.path
request.full_path
request.script_root
request.url
request.base_url
request.url_root
request.host_url
request.host
request.files
obj = request.files[‘the_file_name‘]
obj.save(‘/var/www/uploads/‘ + secure_filename(f.filename))

　　测试代码：

 1 from flask import Flask,request,Response
 2 
 3 app = Flask(import_name=__name__)
 4 
 5 @app.route(‘/index/‘)
 6 def index():
 7     print("request.method:",request.method)
 8     print("request.args:",request.args)
 9     print("request.form:",request.form)
10     print("request.values:",request.values)
11     print("request.cookies:",request.cookies)
12     print("request.headers:",request.headers)
13     print("request.path:",request.path)
14     print("request.full_path:",request.full_path)
15     print("request.script_root:",request.script_root)
16     print("request.url:",request.url)
17     print("request.base_url:",request.base_url)
18     print("request.url_root:",request.url_root)
19     print("request.host_url:",request.host_url)
20     print("request.files:",request.files)
21     return Response("index")
22 
23 if __name__ == ‘__main__‘:
24     app.run()

View Code

　　使用浏览器访问：http://127.0.0.1:5000/index/?a=1&b=2

　　执行结果：

request.method: GET
request.args: ImmutableMultiDict([(‘a‘, ‘1‘), (‘b‘, ‘2‘)])
request.form: ImmutableMultiDict([])
request.values: CombinedMultiDict([ImmutableMultiDict([(‘a‘, ‘1‘), (‘b‘, ‘2‘)]), ImmutableMultiDict([])])
request.cookies: {‘sessionid‘: ‘o3fu279ez1lnsuoung8udxc95sxbglde‘, ‘csrftoken‘: ‘ISStt8sv8ATqEPt0MWfHiy6sqNSmz0GYB35Yam3SyAGcYBRzxnx4rsbr1XeNDF3I‘}
