Example #1

Design the choiceField() in the chúng tôi with the values it needs to display and process in the choices attribute of the field.

forms.py:

from django import forms class requestcheckform(forms.Form): request_attribute = forms.ChoiceField(choices=[('Request Header','Request Header'), ('Request POST','Request POST'), ('Request Files','Request Files'), ('Request GET','Request GET'), ('Request User','Request User'), ('Request Body','Request Body'), ('Request Content Type','Request Content Type'), ('Request Encoding','Request Encoding'), ('Request Method','Request Method'), ('Request Cookies','Request Cookies'), ('Request Path','Request Path'), ('Request META','Request META'), ('Request port','Request port'), ('Request host','Request host'), ('Request is_secure','Request is_secure'), Example #2

Formulate the view function for capturing all the request attributes and methods and post them to the messages. Success () prompt allows us to prompt the messages retrieved again into the screen.

from django.shortcuts import render from chúng tôi import HttpResponse from Django_app1.forms import Valueform,fileform,emailform,requestcheckform import requests def requestmethods(request): form = requestcheckform() if request.method == 'POST': # REQUEST OBJECT ATTRIBUTES if request.POST['request_attribute'] == 'Request Header': data_content = "data content of request method: " + str(request.headers) messages.success(request,data_content) elif request.POST['request_attribute'] == 'Request POST': post_content = "post content of request method: " + str(request.POST) messages.success(request,post_content) elif request.POST['request_attribute'] == 'Request Files': FILES_content = "FILES in request method: " + str(request.FILES) messages.success(request,FILES_content) elif request.POST['request_attribute'] == 'Request GET': GET_content = "GET Content in request method: " + str(request.GET) messages.success(request,GET_content) elif request.POST['request_attribute'] == 'Request User': Request_User = "User Details: " + str(request.user) messages.success(request,Request_User) elif request.POST['request_attribute'] == 'Request Body': Request_body = "Request Body: " + str(request.body) messages.success(request,Request_body) elif request.POST['request_attribute'] == 'Request Content Type': Request_Content_Type = "Request Content type: " + str(request.content_type) messages.success(request,Request_Content_Type) elif request.POST['request_attribute'] == 'Request Encoding': Request_Encoding = "Request Encoding Used: " + str(request.encoding) messages.success(request,Request_Encoding ) elif request.POST['request_attribute'] == 'Request Method': messages.success(request,Request_method ) elif request.POST['request_attribute'] == 'Request Path': Request_path = "Path of the request: " + str(request.path) messages.success(request,Request_path ) elif request.POST['request_attribute'] == 'Request Cookies': Request_Cookies = "Cookies associated to the Request: " + str(request.COOKIES) messages.success(request,Request_Cookies ) elif request.POST['request_attribute'] == 'Request META': Request_META = "HTTP headers info: " + str(request.META) messages.success(request,Request_META ) # REQUEST METHODS elif request.POST['request_attribute'] == 'Request port': Request_port = "Request port number: " + str(request.get_port()) messages.success(request,Request_port ) elif request.POST['request_attribute'] == 'Request host': Request_host = "Requested Host: " + str(request.get_host()) messages.success(request,Request_host) elif request.POST['request_attribute'] == 'Request is_secure': Request_secure = "Security level of the request: " + str(request.is_secure()) messages.success(request,Request_secure) return render(request,'Request_methods_check.html',{"form":form}) Example #3
