Question

我在python3.7上使用Distance Matrix API，在我的本地计算机上工作正常，但是当我在Google App Engine上部署它时，出现以下错误：

Traceback (most recent call last):    
File "/env/lib/python3.7/site-packages/flask/app.py", line 2292, in wsgi_app      response = self.full_dispatch_request()

File "/env/lib/python3.7/site-packages/googlemaps/client.py", line 290, in _get_body      body.get("error_message"))  googlemaps.exceptions.ApiError: INVALID_REQUEST

我的代码：

def retrieve_cities(string):
    lats=[]
    lons=[]
    for item in string.split("|"):
        lats.append(float(item.split(",")[0]))
        lons.append(float(item.split(",")[1]))
    return zip(lats,lons)

def build_distance(nodes):
    if True:
        Sgmaps = googlemaps.Client(key='[KEY]')
        result = gmaps.distance_matrix(nodes, nodes, mode='driving') #<<< ERROR HERE

def vr():
    n = "31.94,35.93|29.16,36.07|31.94,35.92|31.94,35.92|30.82,35.97"
    cities = retrieve_cities(n)
    distances = build_distance(cities)
    #(path, distance) = find_route(distances,cities)
    #data = {"distance":distance,"path":path,"message":""}
    return jsonify(distances)

能否请您说明为什么它可以在本地主机上而不在Google App引擎环境上运行？

INVALID_REQUEST：Google App Engine上的距离矩阵API
