概述: 服务器接收http请求后,会根据报文创建HttpRequest对象 视图的第一个参数就是HttpRequest对象 django创建的,之后调用视图时传递给视图 属性 path:请求的完整路径(不包括域名和端口) method:表示请求的方式,常用的有GET,POST encoding:表示浏览器提交的数据的编码方式,一般为utf-8 GET:类似于字典的对象,包含了get请求的所有参数 POST:类似于字典的对象,包含了post请求的所有参数 FILES:类似字典的对象,包含了所有上传的文件 COOKIES:字典,包含所有的cookie session:类似字典的对象,表示当前会话 方法 is_ajax():如果是通过XMLHttpRequest发起的,返回 True QueryDict对象 request对象中的GET,POST都属于QueryDict对象 方法: get(): 根据键获取值,只能获取一个值 www.sunck.wang/abc?a=1&b=2&c=3 getlist() 将键的值以列表的形式返回 可以获取多个值 www.sunck.wang/abc?a=1&b=2&c=3 GET属性 获取浏览器传递过来数据 www.sunck.wang/abc?a=1&b=2&c=3 urls.py url(r‘^get1‘, views.get1), #结尾不能加$,否则无法匹配 views.py def get1(request): a = request.GET.get(‘a‘) b = request.GET.get(‘b‘) c = request.GET.get(‘c‘) return HttpResponse(a + " " + b + " " + c) www.sunck.wang/abc?a=1&a=2&c=3 urls.py url(r‘^get2‘, views.get2), views.py def get2(request): a = request.GET.getlist(‘a‘) a1 = a[0] a2 = a[1] c = request.GET.get(‘c‘) return HttpResponse(a1 + " " + a2 + " " + c) POST属性 使用表单模拟POST请求 关闭CSRF:project\project\settings.py MIDDLEWARE = [ ‘django.middleware.security.SecurityMiddleware‘, ‘django.contrib.sessions.middleware.SessionMiddleware‘, ‘django.middleware.common.CommonMiddleware‘, # ‘django.middleware.csrf.CsrfViewMiddleware‘, ‘django.contrib.auth.middleware.AuthenticationMiddleware‘, ‘django.contrib.messages.middleware.MessageMiddleware‘, ‘django.middleware.clickjacking.XFrameOptionsMiddleware‘, ] 示例: def showregist(request): return render(request, ‘myApp/regist.html‘,) def regist(request): name = request.POST.get("name") gender = request.POST.get("gender") age = request.POST.get("age") hobby = request.POST.getlist("hobby") print(name) print(gender) print(age) print(hobby) return HttpResponse("regist") 路径: url(r‘^showregist/$‘, views.showregist), url(r‘^showregist/regist/$‘, views.regist), 页面: <!doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>注册</title> </head> <body> <form action="regist/" method="post"> 姓名:<input type="text" name="name" value=""/> <hr> 性别:<input type="radio" name="gender" value="1">男<input type="radio" name="gender" value="0">女 <hr> 爱好:<input type="checkbox" name="hobby" value="power"/>权利<input type="checkbox" name="hobby" value="money">金钱<input type="checkbox" name="hobby" value="beauty">美女<input type="checkbox" name="hobby" value="Tesla">Tesla <hr> <input type="submit" value="注册"> </form> </body> </html>
