1.7 响应响应格式和状态码
Django默认响应格式是text/html，同时也给我们提供了修改的方式
def hello(request):
filepath=os.path.join(settings.BASE_DIR, "shn","hello_world.html")
with open (filepath,"r") as f:
content=f.read()
return HttpResponse(content, content_type = "text/html", status = 200 )
#content_type="text/html" 响应的格式是html格式，也可以改为纯文件格式cotent-type
#status=200 默认响应码是200，也可以修改成其他的3位数字
