I want to get elevation data from Google Earth according to latitude and longitude, but I am not able to do this. I'm not sure what I'm doing wrong but my code is shown below.
def getElevation(locations,sensor="true", **elvtn_args):
elvtn_args.update({
'locations': locations,
'sensor': sensor
})
url = ELEVATION_BASE_URL
params = urllib.parse.urlencode(elvtn_args)
baseurl = url +"?"+ params;
req = urllib.request.urlopen(str(baseurl));
response = simplejson.load(req);
And the error I get is :
Traceback (most recent call last):
File "D:\GIS\Arctools\ElevationChart - Copy.py", line 85, in <module>
getElevation(pathStr)
File "D:\GIS\Arctools\ElevationChart - Copy.py", line 45, in getElevation
response = simplejson.load(req);

obj, end = self.raw_decode(s, idx=_w(s, 0).end())
TypeError: can't use a string pattern on a bytes-like object
Any help appreciated.
The most common way to handle JSON parse error is using try-catch block. If the JSON string is valid, it will return a JavaScript object. If the JSON string is invalid, it will throw a SyntaxError.
Follow these steps to resolve your invalid JSON formatting error. Verify that the service account credentials are in a valid JSON format. Tip: An online JSON formatter can identify problems with the JSON format. If the error persists, generate a new service account credentials key.
It means that the editor failed to get a response to the server or the response wasn't in a valid JSON format. Basically, if the editor can't communicate with the server, it will show this error message instead.
In cases where a JavaScript Object Notation (JSON) transaction fails, the API Gateway can use a JSON Error to convey error information to the client. By default, the API Gateway returns a very basic fault to the client when a message filter has failed.
Post is a little late but recently ran into the same problem. The solution below worked for me. Basically what Lennart said.
from urllib import request
import json
req = request.urlopen('https://someurl.net/api')
encoding = req.headers.get_content_charset()
obj = json.loads(req.read().decode(encoding))
