Install Client Libraries

The Google Street View Publish API is built on HTTP and JSON, so any standard HTTP client can send requests to it and parse the responses.

However, the Google API client libraries provide better language integration, improved security, and support for making calls that require user authorization. The client libraries are available in a number of programming languages; by using them you can avoid the need to manually set up HTTP requests and parse the responses.

To get started, select the programming language that you are using for development. We are still adding more languages.

Note: We now offer a client library in Go. See documentation at https://pkg.go.dev/cloud.google.com/go/streetview/publish/apiv1/publishpb

Python

See the Python Package Index instructions for gapic-google-maps-streetview_publish.

After this module is installed, you can test it with the following code to upload a photo.

from google.streetview.publish_v1.proto import resources_pb2
from google.streetview.publish_v1 import street_view_publish_service_client as client
from oauth2client.client import OAuth2WebServerFlow

  client_id = 'Your client ID'
  client_secret = 'Your client secret'
  flow = OAuth2WebServerFlow(client_id=client_id,
                             client_secret=client_secret,
                             scope='https://www.googleapis.com/auth/streetviewpublish',
                             redirect_uri='http://example.com/auth_return')

  # Open a web browser to ask the user for credentials.
  credentials = run_flow(flow, storage)
  assert credentials.access_token is not None
  return credentials.access_token

token = get_access_token()

# Create a client and request an Upload URL.
streetview_client = client.StreetViewPublishServiceClient(credentials=credentials)
upload_ref = streetview_client.start_upload()
print("Created upload URL: " + str(upload_ref))

# Upload the photo bytes to the Upload URL.
with open("/path/to/your/file.jpg", "rb") as f:
  print("Uploading file: " + f.name)
  raw_data = f.read()

      "X-Goog-Upload-Content-Length": str(len(raw_data)),
  }
  r = requests.post(upload_ref.upload_url, data=raw_data, headers=headers)
  print("Upload response: " + str(r))

# Upload the metadata of the photo.
photo = resources_pb2.Photo()
photo.upload_reference.upload_url = upload_ref.upload_url
photo.capture_time.seconds = int(time.time())
photo.pose.heading = 105.0
photo.pose.lat_lng_pair.latitude = 46.7512623
photo.pose.lat_lng_pair.longitude = -121.9376983
create_photo_response = streetview_client.create_photo(photo)
print("Create photo response: " + str(create_photo_response))

Java
