Django框架中定位URL的render、redirect和HttpResponse方法區別

Django中在views裏有3種返回url的形式：

HttpResponse：可以直接返回一個html頁

 

render：用於頁面渲染，需要傳入request參數，除了html文件名，還可以傳數據到頁面上，源碼裏的介紹如下：實際還是調用HttpResponse

def render(request, template_name, context=None, content_type=None, status=None, using=None):
    """
    Return a HttpResponse whose content is filled with the result of calling
    django.template.loader.render_to_string() with the passed arguments.
    """
    content = loader.render_to_string(template_name, context, request, using=using)
    return HttpResponse(content, content_type, status)

redirect：進行直接跳轉，做頁面的重定向，方法源碼裏的介紹如下：

def redirect(to, *args, permanent=False, **kwargs):
    """
    Return an HttpResponseRedirect to the appropriate URL for the arguments
    passed.

    The arguments could be:

        * A model: the model's `get_absolute_url()` function will be called.

        * A view name, possibly with arguments: `urls.reverse()` will be used
          to reverse-resolve the name.

        * A URL, which will be used as-is for the redirect location.

    Issues a temporary redirect by default; pass permanent=True to issue a
    permanent redirect.
    """
    redirect_class = HttpResponsePermanentRedirect if permanent else HttpResponseRedirect
    return redirect_class(resolve_url(to, *args, **kwargs))
