请求多值参数的url编码

Question

使用请求库如何创建一个多值int参数？ 我试图给出一个原点到谷歌地图的API，但不能让它编码正确

start_coordinates = {'latitude':40.970321, 'longitude' :29.060873} 
end_coordinates = {'latitude':41.029967, 'longitude' :28.974656} 

start_latitude = start_coordinates.get('latitude') 
start_longitude = start_coordinates.get('longitude') 
end_latitude = end_coordinates.get('longitude') 
end_longitude = end_coordinates.get('latitude') 

url = 'http://maps.googleapis.com/maps/api/directions/json' 
params = { 
    'origin' : '%s,%s' %(start_latitude,start_longitude), 
    'destination' : '%s,%s' %(end_latitude, end_longitude), 
    'sensor' : 'false', 
    } 
google_response = requests.get(url,params=params) 

的google_response是：

u'http://maps.googleapis.com/maps/api/directions/json?origin=40.970321%2C29.060873&destination=28.974656%2C41.029967&sensor=false'

，但它应该是：

u'http://maps.googleapis.com/maps/api/directions/json?origin=40.970321,29.060873&destination=28.974656,41.029967&sensor=false'

其中的参数应该像origin=40.970321,29.060873而不是destination=28.974656%2C41.029967

另一个例子：

这并不工作： http://maps.googleapis.com/maps/api/directions/json?origin=40.970321%2C29.060873&destination=28.974656%2C41.029967&sensor=false

这个工程： http://maps.googleapis.com/maps/api/directions/json?origin=40.970321,29.060873&destination=41.029967,28.974656&sensor=false

它显然是在我的部分错误似乎：

well this is embarrassing. It was my first few lines that threw the code off, it should be: 

start_coordinates = {'latitude':40.970321, 'longitude' :29.060873} 
end_coordinates = {'latitude':41.029967, 'longitude' :28.974656} 
start_latitude = start_coordinates.get('latitude') 
start_longitude = start_coordinates.get('longitude') 
end_latitude = end_coordinates.get('latitude') 
end_longitude = end_coordinates.get('longitude') 


url = 'http://maps.googleapis.com/maps/api/directions/json' 
params = { 
    'origin' : '%s,%s' %(start_latitude,start_longitude), 
    'destination' : '%s,%s' %(end_latitude, end_longitude), 
    'sensor' : 'false', 
    } 
google_response = requests.get(url, params=params) 

我得到了end_longitude和end_latitude错误。因此，这修复它

如果你坚持一个decodec网址，试试这个：

In [54]: urllib.unquote(google_response.url).decode('utf8') 
Out[54]: u'http://maps.googleapis.com/maps/api/directions/json?origin=40.970321,29.060873&destination=28.974656,41.029967&sensor=false' 

编辑：由于urllib的改变排序（我认为这是由于使用的字典内），这种方法没有按”不管工作。我建议手动构建网址，通过pythons字符串连接/格式化方法。
