自己也要分清楚 看清楚 request,response
一个是请求 一个是相应
行 头 之间还有个空行 体
HttpRequest请求对象(只读)
-
当用户访问一个视图函数时,Django会创建一个request对象(HttpRequest)
-
HttpRequest对象中封装了所有的Http协议中的请求信息
常见属性和方法
HttpRequest.scheme:返回协议类型(http/https)
HttpRequest.body:返回请求实体内容
HttpRequest.path:返回请求地址
HttpRequest.method:返回当前请求方式(GET/POST)
HttpRequest.GET:返回当前请求参数的字典QueryDict
HttpRequest.POST:返回当前请求参数的字典QueryDict
HttpRequest.COOKIES:返回客户端所有的cookie信息
HttpRequest.FILES:获取上传文件(1.要求POST请求2.enctype="multipart/form-data)
HttpRequest.META:返回请求报文信息
HttpRequest.get_host():返回请求主机名和端口号
HttpRequest.get_full_path():返回请求地址(包括请求参数)
HttpResponse 响应对象
用法
#响应内容
>>> from django.http import HttpResponse
>>> response = HttpResponse("Here's the text of the Web page.")
>>> response = HttpResponse("Text only, please.", content_type="text/plain")
>>> response = HttpResponse()
>>> response.write("<p>Here's the text of the Web page.</p>")
>>> response.write("<p>Here's another paragraph.</p>")
>>> response = HttpResponse(my_data, content_type='application/vnd.ms-excel')
>>> response['Content-Disposition'] = 'attachment; filename="foo.xls"'
#设置响应头信息
response = HttpResponse('hello')
response.__setitem__('hello','123')
response = HttpResponse('hello')
response['uname']='zhangsan'
response.setdefault('Server','WBS')
