找不到页面（404）错误，我没有写网址

Question

I got an error,Page not found (404) Request Method: GET Request URL: http://localhost:8000/app/test.html?prop=value . 我收到一个错误，找不到页面（404）请求方法：GET请求URL： http://localhost:8000/app/test.html?prop=value 。 I wrote index.html like 我写了index.html像

<body>
　  <form method="post" action="">
    <select id="mainDD" data-placeholder="Choose" class="chzn-select" style="width:600px;">
    {% for i in json_data.items.values %}
            <option value="{{forloop.counter}}">{{ i }}</option>
    {% endfor %}
    </select>

    {% for key, values in preprocessed %}
    <select name="type" id=type{{forloop.counter}}>
    {% for counter, value in values %}
        <option value="{{forloop.counter}}">{{ value }}</option>
    {% endfor %}
    </select>
    {% endfor %}
    </form>

  <script type="text/javascript">

        $(document).ready(function () {
            $('#mainDD').on('change', function() {
              var thisType = "type" + $(this).val();
              for(i=1; i<6; i++) {
                  var thisId = "type" + i;
                  if(thisType !== thisId) {
                    $("#"+thisId).hide();
                  }
                  else {
                    $("#"+thisId).show();
                  }
              }

            }).trigger('change');

        });


  </script>

     <form id="postform" action="http://localhost:8000/app/test_view" method="POST">
      {% csrf_token %}
      <input type="submit" value="SEND">
     </form>
     <script type="text/javascript">
        let key = "prop";
        let value = "value";
        var array1 = [];
        var array2 =[];
          document.querySelector("input[type=submit]").onclick = e => {
           const test = window.open(`test.html?${key}=${value}`, "_blank");
          }

     </script>
  </body>

This part const test = window.open('test.html?${key}=${value}', "_blank"); 这部分const test = window.open('test.html?${key}=${value}', "_blank"); causes error because I did not regist url http://localhost:8000/app/test.html?prop=value . 导致错误，因为我没有注册url http://localhost:8000/app/test.html?prop=value 。 I only register http://localhost:8000/app/test_view . 我只注册http://localhost:8000/app/test_view 。 But I wanna send selected i & value's values to test.html,so I wrote this like. 但是我想将选定的i＆value的值发送到test.html，所以我这样写。 I wrote in test.html like 我在test.html这样写

<body>

<h2>RESULT</h2>
    <script type="text/javascript">

      onload = () => {
        document.body.appendChild(
          document.createTextNode([...new URLSearchParams(location.search).entries()])
          );
      }

    </script>

</body>

How should I fix this?What should I write this? 我该如何解决？我该怎么写？

urls.py is urls.py是

urlpatterns = [
    url(r'^$', views.index, name='index'),
    url(r'^test_view$', views.test_view, name='test_view'),
]

views.py is views.py是

def test_view(request):
    return render(request, 'test.html')

My app structure is testapp(parent app) -app(child app) -inde.html&test.html&views.py 我的应用程序结构是testapp（父应用程序）-app（子应用程序）-inde.html＆test.html＆views.py

testapp's urls.py is testapp的urls.py是

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^app/', include('app.urls')),
]

Now my code is 现在我的代码是

<form id="postform" action="http://localhost:8000/app/test_view" method="GET">
      {% csrf_token %}
      <a href={% url 'test_view' %}>Your link to test view</a>
     </form>
     <script type="text/javascript">
        let key = "prop";
        let value = "value";
        var array1 = [];
        var array2 =[];
          document.querySelector("input[type=submit]").onclick = e => {
           const test = window.open(`test.html?${key}=${value}`, "_blank");
          }

     </script>

Answer 1

You registred http://localhost:8000/app/test_html but try to go by http://localhost:8000/app/test.html link. 您注册了http://localhost:8000/app/test_html但尝试通过http://localhost:8000/app/test.html链接进入。 Your GET parameters don't make a sense. 您的GET参数没有任何意义。

You should use url, that you registred in urls.py . 您应该使用在urls.py url。
Read this tutorial about views and urls. 阅读有关视图和URL的本教程。

Change action attribute in your form. 更改表单中的action属性。 It might looks like that: 可能看起来像这样：

In your template your link may looks like this: 在您的模板中，您的链接可能如下所示：

<form id="postform" action="{% url 'test_view' %}" method="GET">

or: 要么：

<form id="postform" action="app/test_view" method="GET">

Instead of: 代替：

<form id="postform" action="http://localhost:8000/app/test_view" method="POST">

This is because in action or another place where you add your url, when you develop in local machine you should write url path without domain: 这是因为在action或添加URL的其他地方，当您在本地计算机上进行开发时，应编写没有域的URL路径：
app/test_view instead of http://localhost:8000/app/test_view app/test_view而不是http://localhost:8000/app/test_view
