Installation

$ pip install vcap_services

Usage

from vcap_services import load_from_vcap_services
credentials = load_from_vcap_services('personality_insights')
print(credentials);

If VCAP_SERVICES is:

  "personality_insights": [{
      "credentials": {
        "password": "<password>",
        "url": "<url>",
        "username": "<username>"
      },
    "label": "personality_insights",
    "name": "personality-insights-service",
    "plan": "standard"
  }]
}

{
  "password": "<password>",
  "url": "<url>",
  "username": "<username>"
}
