RPA.Cloud.Google

Description

Google is a library for operating with Google API endpoints.

Usage requires the following steps:

  • Create a GCP project
  • Create a service account key file (JSON) and save it to a place the robot can use it
  • Enable APIs
  • Install rpaframework[google]

Google authentication

Authentication for Google is set with service credentials JSON file which can be given to the library in three different ways.

  • Method 1 as environment variables, GOOGLE_APPLICATION_CREDENTIALS with path to JSON file.
  • Method 2 as keyword parameter to Init Storage Client for example.
  • Method 3 as Robocloud vault secret. The vault name and secret key name needs to be given in library init or with keyword Set Robocloud Vault. Secret value should contain JSON file contents.

Method 1. service credentials using environment variable

*** Settings ***
Library   RPA.Cloud.Google

*** Tasks ***
Init Google services
    # NO parameters for Vision Client, expecting to get JSON
    # with GOOGLE_APPLICATION_CREDENTIALS environment variable
    Init Vision Client

Method 2. service credentials with keyword parameter

*** Settings ***
Library   RPA.Cloud.Google

*** Tasks ***
Init Google services
    Init Speech To Text Client  /path/to/service_credentials.json

Method 3. setting Robocloud Vault in the library init

*** Settings ***
Library   RPA.Cloud.Google
...       robocloud_vault_name=googlecloud
...       robocloud_vault_secret_key=servicecreds

*** Tasks ***
Init Google services
    Init Storage Client   use_robocloud_vault=${TRUE}

Method 3. setting Robocloud Vault with keyword

*** Settings ***
Library   RPA.Cloud.Google

*** Tasks ***
Init Google services
    Set Robocloud Vault   vault_name=googlecloud  vault_secret_key=servicecreds
    Init Storage Client   use_robocloud_vault=${TRUE}

Requirements

Due to number of dependencies related to Google Cloud services this library has been set as an optional package for rpaframework.

This can be installed by opting in to the google dependency:

pip install rpaframework[google]

Examples

Robot Framework

*** Settings ***
Library   RPA.Cloud.Google

*** Variables ***
${SERVICE CREDENTIALS}    ${/}path${/}to${/}service_credentials.json
${BUCKET_NAME}            testbucket12213123123

*** Tasks ***
Upload a file into a new storage bucket
    [Setup]   Init Storage Client   ${SERVICE CREDENTIALS}
    Create Bucket    ${BUCKET_NAME}
    Upload File      ${BUCKET_NAME}   ${/}path${/}to${/}file.pdf  myfile.pdf
    @{files}         List Files   ${BUCKET_NAME}
    FOR   ${file}  IN   @{files}
        Log  ${file}
    END

Python

from RPA.Cloud.Google import Google

library = Google
service_credentials = '/path/to/service_credentials.json'

library.init_vision_client(service_credentials)
library.init_text_to_speech(service_credentials)

response = library.detect_text('imagefile.png', 'result.json')
library.synthesize_speech('I want this said aloud', target_file='said.mp3')
