Question

目标：

返回99个人的驾驶时间（我从一个'起点'和'目的地'开始，以确保我的格式正确），'起源'和'目的地'以JSON格式。

但是，我收到以下错误：“HTTPError：HTTP Error：400”

总的来说，我使用的是Python 2.7，这是我最初的API尝试，因此非常感谢您对该事业的任何帮助！

仅供参考：我使用以下GitHub作为构建代码的蓝图： https://github.com/googlemaps/google-maps-services-python/blob/master/googlemaps/distance_matrix.py

代码：

import googlemaps
from googlemaps import convert
from googlemaps.convert import as_list


#API key
key = 'xxxxx'
client = googlemaps.Client(key)


#establishes: drive duration, english, non-metric measurements
def distance_matrix(client, origins, destinations,
                    mode="driving", language="en", avoid=None, units="imperial",
                    departure_time="calendar.timegm(time.gmtime())", arrival_time=None, transit_mode=None,transit_routing_preference=None):

    #establishes "origin" and "destinations" geoInfo via the .json structure
    params = {
    "origins": '1218 3rd St, Santa Monica, 90401, CA',
    "destinations": '90278'
}

    if mode:
        # NOTE(broady): the mode parameter is not validated by the Maps API
        # server. Check here to prevent silent failures.
        if mode not in ["driving", "walking", "bicycling", "transit"]:
            raise ValueError("Invalid travel mode.")
        params["mode"] = mode

    if language:
        params["language"] = language

    if avoid:
        if avoid not in ["tolls", "highways", "ferries"]:
            raise ValueError("Invalid route restriction.")
        params["avoid"] = avoid

    if units:
        params["units"] = units

    if departure_time:
        params["departure_time"] = convert.time(departure_time)

    if arrival_time:
        params["arrival_time"] = convert.time(arrival_time)

    if departure_time and arrival_time:
        raise ValueError("Should not specify both departure_time and"
                         "arrival_time.")

    if transit_mode:
        params["transit_mode"] = convert.join_list("|", transit_mode)

    if transit_routing_preference:
        params["transit_routing_preference"] = transit_routing_preference

    return client._get("/maps/api/distancematrix/json", params)


print distance_matrix(client, "origins", "destinations")

完成错误消息追溯：

HTTPError: HTTP Error: 400

Answer 1

根据Google的文档，当您获得400响应代码时，它可能是无效参数或 badRequest 。如果：

参数无效：表示请求参数的值无效。错误响应中的locationType和location字段提供有关哪个值无效的信息。

如果不解决问题，请勿重试。您需要为错误响应中指定的参数提供有效值。

错误请求：表示查询无效。例如，缺少父ID或请求的维度或指标的组合无效。

如果不解决问题，请勿重试。您需要对API查询进行更改才能使其生效。

我认为问题在于API密钥。如果即使没有API_KEY也不请求配额，也可以使用Direction API。在代码中提供的示例代码中，我看不到API_KEY被放在client参数中。

#API key
key = 'xxxxx'
client = googlemaps.Client(key)
