django响应方法后don'；t呈现到html模板

我在视图中有两个请求函数，一个是.get方法，另一个是.post。这两个函数都能正常工作，因为终端中的代码是200

[01/Apr/2021 08:04:39]“获取/搜索/搜索HTTP/1.1”200 4164 [01/Apr/2021 08:04:57]“发布/搜索/搜索HTTP/1.1”200 4164

当我尝试使用.post方法将函数呈现到html模板时，问题就出现了。html页面上没有显示任何内容

def wind_search(request):
if request.method == 'post':
        city = request.post['city']
        weather_city_url = urllib.request.urlopen('api.openweathermap.org/data/2.5/weather?q=' + city + '&appid=1a7c2a40a0734d1dc18141fc6b6241bb').read()
        list_of_data = json.loads(waether_city_url)


        # main wind information
        wind_speed = list_of_data['wind']['speed']
            # wind_gust = wea['current']['wind_gust']
        wind_deg = list_of_data['wind']['deg']
        # wind conversiont m/s to knots
        def wind_converter(w):
            knots = 2
            kt = (float(w)) * knots
            return kt

        wind_response = wind_converter(wind_speed)
        #convert wind degree in cardinal direction.
        def degrees_to_cardinal(d):

            dirs = ['N', 'NNE', 'NE', 'ENE', 'E', 'ESE', 'SE', 'SSE', 'S', 'SSW', 'SW', 'WSW', 'W', 'WNW', 'NW', 'NNW']
            ix = round(d / (360. / len(dirs)))
            return dirs[ix % len(dirs)]

        direction = degrees_to_cardinal(wind_deg)

        wind_data = {

        "wind_response":wind_response,
        "wind_direction":direction,
        }

else:
    wind_data={}

    context = {"wind_data":wind_data}
return render(request, 'API/wind_search.html',context)

这是html模板：

    {% extends "API/base.html" %}
{% block content %}


<!--Jumbotron -->
 <div class="jumbotron jumbotron-fluid">
  <div class="container">
    <h1 class="display-4">Wind search</h1>
    <p class="lead">Write the city and check th wind condition. </p>
<!-- form input search tool -->
 <nav class="navbar navbar-expand-lg navbar-dark">
    <form method="post" class="col-md"">
      {% csrf_token %}
      <div class=" input-group">
      <input type="text" class="form-control" name="city" placeholder="Choose Your City ...">
      <div class="input-group-btn">
        <button type="submit" class="btn btn-primary">Search</button>
      </div>
      </div>

      </form>
  </nav>
  <div class="row">
    {% if wind_response and wind_direction %}
        <h4><span>Wind Speed :</span> {{wind_data.wind_speed}}</h4>
        <h4><span>Wind_Direction :</span> {{wind_data.wind_direction}}</h4>
      </div>
      {% endif %}
    </div>

{% endblock content %}

{%extends“API/base.html”%}
{%block content%}
风向搜索
写下城市并检查风力状况
请设置渲染和重定向模板

def wind_搜索（请求）：
如果request.method==“POST”：
#这段代码管理是否有POST请求。。。
city=request.POST.get（'city'）
weather_city_url=urllib.request.urlopen（'api.openweathermap.org/data/2.5/weather？q='+city+'&appid=1a7c2a40a0734d1dc18141fc6b6241bb'）。read（）

#主要风力资料
风速=风数据列表['wind']['speed']
#风阵风=wea['current']['wind\u gust']
风度=风数据列表['wind']['deg']
#风速转换为节数
def风电转换器（w）：
节数=2
kt=（浮子（w））*节
返回kt
风响应=风转换器（风速）
#将风向转换为基本方向。
def度数到基数（d）：
dirs=['N'，'NNE'，'NE'，'ENE'，'E'，'ESE'，'SE'，'SSE'，'S'，'SSW'，'SW'，'WSW'，'W'，'WNW'，'NW'，'NNW']

风电数据={
“风响应”：风响应，
“风向”：风向，
}
#提交POST请求后要加载的页面尚未呈现POST响应。您的程序中只有一个渲染，请您更具体一点，我不明白。我的意思是函数末尾的渲染对POST方法不起作用？行
context={“wind\u data”：wind\u data}
不应该缩进。现在，它是
else:
块的一部分。还要检查模板中的
风响应
和
风向
参考，以确保它们与
上下文
数据匹配。我移除缩进并检查参考，但仍然相同，还有其他建议吗？
