I'm trying to connect my code with google maps api(geocoding API) key. But when I run my code, the ValueError occurs. I don't know why. It might be silly, but please help me.
Here's my python code.
import httplib2
import json
def getGeocodeLocation(inputString):
google_api_key = "MY_API_KEY"
locationString = inputString.replace(" ", "+")
url = ('https://maps.googleapis.com/maps/api/geocode/json?address=%s & key=%s' % (locationString, google_api_key))
h = httplib2.Http()
response, content = h.request(url, 'GET')
result = json.loads(content)
print "response header: %s \n \n" % response
return result
And here's the error.
>>> from geocode import getGeocodeLocation
>>> getGeocodeLocation("Dalls, Texas")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "geocode.py", line 10, in getGeocodeLocation
result = json.loads(content)
File "/usr/lib/python2.7/json/__init__.py", line 339, in loads
return _default_decoder.decode(s)
File "/usr/lib/python2.7/json/decoder.py", line 364, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/usr/lib/python2.7/json/decoder.py", line 382, in raw_decode
raise ValueError("No JSON object could be decoded")
ValueError: No JSON object could be decoded
Thanks.

When I edited the code from,
response, content = h.request(url, 'GET')
result = json.loads(content)
print "response header: %s \n \n" % response
to
response, content = h.request(url, 'GET')
print "response header: %s \n \n" % response
result = json.loads(content)
The result was like this.

You are having an error in your request. The status code is 400 Bad Request, and the content of your response is:
Your client has issued a malformed or illegal request. That's all we know.
There error seems to be on this line:
url = ('https://maps.googleapis.com/maps/api/geocode/json?address=%s & key=%s' % (locationString, google_api_key))
You shouldn't have blank spaces around the & sign:
url = ('https://maps.googleapis.com/maps/api/geocode/json?address=%s&key=%s' % (locationString, google_api_key))
