Python 在Views.py中使用外部脚本

我有一个向API发送请求并检索信息的文件。我们将此文件称为get_info.py。我现在正在构建一个GUI，它使用Django和views.py文件，使用方法“GET”和“POST”

我现在将函数从get_info.py导入views.py，并按如下方式使用它

from get_info import get_info
@api_view(['GET'])
def generate_route(request):
    """
    :param request:
    1. lat: posx
    2. lng: pos,
    3. r: radius in km
    4. strategy,
    5. edge_num,
    6. deep,
    :return:
    """
    posx = request.query_params.get('lat', None)
    posy= request.query_params.get('lng', None)

    r= request.query_params.get('r', None)
    strategy = request.query_params.get('strategy', None)
    strategy = strategy if strategy else 3
    edge_num = request.query_params.get('edge_num', None)
    edge_num = edge_num if edge_num else 3
    deep = request.query_params.get('deep', None)
    deep = deep if deep else 3
    print("BEFORE", posx, posy, r, strategy, edge_num, deep)
    route = get_info(posx, posy, r)
    print("AFTER", route)
    if request.query_params.get('lat', None) is not None \
            and request.query_params.get('lng', None) is not None \
            and request.query_params.get('r', None) is not None:
        return Response({}, status=status.HTTP_200_OK)
    else:
        return Response({
            "Error": 'Need lat, lng, and r {}'.format(request.query_params.get('lat', None))
        }, status=status.HTTP_400_BAD_REQUEST)
```

然而，我得到了回应

但当我使用from django.httpimport-HttpRequest构建请求时，它告诉我“超出了最大深度”

get_info方法相当长，但简而言之，它看起来是这样的：

def get_info(posx, posy, r, strategy=3, edge_num=0.8, deep=0):  
    req_url = "http://api.map.baidu.com/direction/v2/driving?origin=posx..."
    trip = requests.get(req_url).json()
    return trip

---

当我在python shell中运行这个get_info方法时，它会返回所需的trip。

如果仔细查看导致问题的是rest框架，如果getinfo是APIView，那么它可能需要request作为其第一个参数，而不是posx（字符串）。

route=get_infoposx，posy，r line导致异常。你能包括获取信息吗？包括在内。它很长，但这应该向您展示了它的要点。我尝试将参数更改为get_inforequest以获取_info，它告诉我：AssertionError:“request”参数必须是“django.http.HttpRequest”的实例，而不是“rest_framework.request.request”。这很奇怪，如果有get_info的函数签名和修饰符，可以显示函数签名和修饰符吗？嗯，它没有任何装饰师也许应该？签名是所有参数都是浮点数。请尝试传递请求。_request获取信息并查看是否解决了问题。这意味着私有请求attr可能就是请求本身，并反复调用自身。您可以查找如何从rest http提取django http。或者更改代码，使其运行更加顺畅。在视图内部调用另一个视图对我来说似乎不是一个好模式。您可以考虑将逻辑提取到自己的类，并使用视图作为传递响应的工具。
