Django视图API返回用户输入报错，求代码修正与模板指导

核心错误原因及修复 #

1. 'WSGIRequest' object has no attribute 'request' 错误 #

你把视图函数的参数名写成了requests，和调用API用的requests库重名了。Django把WSGI请求对象传给这个参数后，再调用requests.request()时，实际是在操作WSGIRequest对象而非requests库，所以触发报错。

修正： 把视图函数的参数名改成Django标准的request，确保导入requests库（没导入的话加import requests）。

2. 获取用户输入并替换querystring的'q'值 #

当前代码里search = 'POST'根本没获取用户输入，querystring[0] = search也是错误写法（字典不能用索引访问）。正确做法是从POST请求里拿到用户输入的内容，再赋值给querystring的'q'键。

修正：

search = request.POST.get('search', '')  # 从表单取输入，默认空字符串
querystring = {"q": f"*{search}*", "hl":"en","gl":"US"}  # 直接替换q的值

3. news.html的h1语法错误 #

{{news.views}}是无效模板变量，你需要把API返回的数据传给模板，再在模板里正确引用。

修正：

• 视图里传数据到模板：return render(request, 'news.html', {'news_data': response.json()})
• news.html里改成{{ news_data }}（可根据API返回结构调整，比如取具体字段{{ news_data.some_key }}）

4. 表单代码错误 #

index.html的form标签写法混乱，属性要放在标签内，action应该用Django的url模板标签，且form标签未闭合。

修正：

<form class="form-inline" method="POST" action="{% url 'news' %}" name="news">
  <div class="input-group mb-3">
    {% csrf_token %}
    <input
      type="text"
      class="form-control"
      placeholder="Enter Crypto"
      name="search"
      style="width: 50%; display: block; margin: 0 auto"
    />
    <button
      class="btn btn-outline-primary btn-md"
      type="submit"
      id="button-addon2"
    >
      Search
    </button>
  </div>
</form>

5. 路由冲突问题 #

mysite/urls.py里同时写了path('', include('search.urls'))和path('news/', include('search.urls'))，会导致路由重复（比如/news/news/也能匹配到news视图）。

修正： 只保留path('', include('search.urls'))，因为someapp/urls.py里已经定义了news/路径。

完整修正后的代码 #

views.py #

import requests
from django.shortcuts import render
from django.http import HttpResponse

def index(request):
    return render(request, 'index.html')

def news(request): 
    if request.method == 'POST':
        search = request.POST.get('search', '')
        url = "https://google-finance4.p.rapidapi.com/search/"
        querystring = {"q": f"*{search}*", "hl":"en","gl":"US"}

        headers = {
            "X-RapidAPI-Key": "my api key",
            "X-RapidAPI-Host": "google-finance4.p.rapidapi.com"
        }

        response = requests.request("GET", url, headers=headers, params=querystring)
        print(response.text)
        return render(request, 'news.html', {'news_data': response.json()})
    else:
        return HttpResponse('Error')
