本节目标：
①、提交表单内容
②、通过客户端提交表单新增一篇文章
③、通过Django的forms组件来完成新增一篇文章

=======提交表单内容========

<div>

   <form method="post">

       username:<input class="" name="username" type="text">

       password:<input class="" name="password" type="password">

         <input type="submit" value="确定">

   </form>

</div>

def login(request):

    username=request.POST.get('username','');------------>POST.get('',''),来获取提交值

    password=request.POST.get('password','');

    return render(request,'login.html',{

      'username':username,

        'password':password

    })

项目级路由
urlpatterns = [

    path('admin/', admin.site.urls),

path('blog/', include('blog.blog_urls')),

    path('login/',include('blog.blog_urls'))

]

应用级路由

urlpatterns = [

path('get_article_list',get_article_list),
path('get_article',get_article),
#path('get_detail',get_detail)
path('get_detail/<int:article_ID>',get_detail),
    path('login',login)

]

  <form method="post">

       {%csrf_token%}-----------a用来验证csrf的，原因未知，加上即可

       username:<input class="" name="username" type="text">

       password:<input class="" name="password" type="password">

         <input type="submit" value="确定">

   </form>

======通过客户端提交表单新增一篇文章======

#新增一个帖子

def add(request):

    article_title=request.POST.get('article_title',"");

    article_prief=request.POST.get('article_prief',"");

    article_content = request.POST.get('article_content', "");

    add_article=Article(article_title=article_title,article_prief_content=article_prief,article_content=article_content);

    add_article.save();

    return render(request,'add.html',{

      'article_title':article_title,

        'article_prief':article_prief,

        'article_content': article_content,

  })
