Trying to output my response from Microsoft's Computer Vision API to a .json file, it works with all of the other APIs I've been using so far. With the code below, directly from Microsoft's documentation, I get an error:
Error: the JSON object must be str, not 'bytes'
Removing the parsed = json.loads(data) and using print(json.dumps(data, sort_keys=True, indent=2)) prints out the information for the image that I want, but also says Error and is prefixed with
b
denoting it's in bytes and ending with
is not JSON serializable
I'm just trying to find out how I can get the response into a .json file like i'm able to do with other APIs and am at a loss for how I can possible convert this in a way that will work.
import http.client, urllib.request, urllib.parse, urllib.error, base64, json
API_KEY = '{API_KEY}'
uri_base = 'westus.api.cognitive.microsoft.com'
headers = {
'Content-Type': 'application/json',
'Ocp-Apim-Subscription-Key': API_KEY,
}
params = urllib.parse.urlencode(
{
'visualFeatures': 'Categories, Description, Color',
'language': 'en',
}
)
body = "{'url': 'http://i.imgur.com/WgPtc53.jpg'}"
try:
conn = http.client.HTTPSConnection(uri_base)
conn.request('POST', '/vision/v1.0/analyze?%s' % params, body, headers)
response = conn.getresponse()
data = response.read()
# 'data' contains the JSON data. The following formats the JSON data for display.
parsed = json.loads(data)
print ("Response:")
print (json.dumps(parsed, sort_keys=True, indent=2))
conn.close()
except Exception as e:
print('Error:')
print(e)
Shortly after posting the question, I realized I had missed looking for something: just converting bytes to a string.
found this Convert bytes to a Python string
and was able to modify my code to:
parsed = json.loads(data.decode('utf-8'))
And it seems to have resolved my issue. Now error-free and able to export to .json file like I needed.
