我正在尝试将我的代码连接到google maps api(geocodingapi)密钥。
但是当我运行代码时,ValueError发生了。我不知道为什么。
可能很傻,但请帮帮我。
这是我的python代码。
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
这就是错误。
>>> 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
谢谢。

当我从中编辑代码时,
response, content = h.request(url, 'GET')
result = json.loads(content)
print "response header: %s \n \n" % response
到
response, content = h.request(url, 'GET')
print "response header: %s \n \n" % response
result = json.loads(content)
结果是这样的。

最佳答案
您的请求有错误。状态代码是400错误请求,您的响应内容是:
您的客户端发出了格式错误或非法的请求。我们只知道这些。
这条线上似乎有错误:
url = ('https://maps.googleapis.com/maps/api/geocode/json?address=%s & key=%s' % (locationString, google_api_key))
您不应该在标志周围有空格(&S):
url = ('https://maps.googleapis.com/maps/api/geocode/json?address=%s&key=%s' % (locationString, google_api_key))
