从python obj发送请求

Question

我有一个元组列表，我希望遍历这些元组并通过python请求模块发送http请求。你知道吗

api_schedule = [
{'destination': (51.490527, 0.267840), 'id': 'trial_a', 'origin': (51.430732, 0.239308)},
{'destination': (51.429488, 0.239060), 'id': 'trial_b', 'origin': (51.490518, 0.267578)}]

原点和目标坐标很难正确格式化。googledirections API希望它们采用lat,lng格式，其中lat和lng是float

我反复浏览字典列表如下：

for pair in api_schedule:
    departure_time = time.time()
    origin_lat = str(pair['origin'][0])
    origin_lng = "," + str(pair['origin'][1])
    origin = origin_lat + origin_lng
    destination_lat = str(pair['destination'][0])
    destination_lng = "," + str(pair['destination'][1])
    destination = destination_lat + destination_lng
    params = {
    "origin" : origin,
    "destination" : destination
    "key" : api_Key,
    "departure_time" : departure_time,
    "mode" : mode
    }
    request = requests.Request('GET', url_raw, params=params).prepare()
    print request.url

但是，它返回%2C代替,：

https://maps.googleapis.com/maps/api/directions/json?origin=51.430732%2C0.239308&destination=51.490527&destination=0.26784

如何遍历像这样的元组列表并使用请求正确地计算参数？你知道吗

当我尝试不进行上述操作时，请求以列表的形式查看源数据和目标数据，从而创建如下两个参数：

https://maps.googleapis.com/maps/api/directions/json?origin=51.430732&origin=0.239308

期望输出：

https://maps.googleapis.com/maps/api/directions/json?origin=51.430732,0.239308&destination=51.490527,0.26784

Answer 1

https://maps.googleapis.com/maps/api/directions/json?origin=51.430732%2C0.239308&destination=51.490527,0.26784和https://maps.googleapis.com/maps/api/directions/json?origin=51.430732,0.239308&destination=51.490527,0.26784是相同的。你知道吗

It is correct to use ^{} instead of ^{} in an URL。你准备的params还可以。你知道吗
