| # Actions |
| |
| ## Adding fixed input values to an Action |
| |
| This example builds upon the previous “hello world” example and shows how fixed values can be supplied to the input parameters of an Action. |
| |
| It shows how to: |
| - declare input parameters on the action ‘```hello_world```’ using a single-line grammar. |
| - add ‘```name```’ and ‘```place```’ as input parameters with the fixed values “```Sam```” and “```the Shire```” respectively. |
| |
| ### Manifest File |
| #### _Example: “Hello world” with fixed input values for ‘name’ and ‘place’_ |
| ```yaml |
| packages: |
| hello_world_package: |
| version: 1.0 |
| license: Apache-2.0 |
| actions: |
| hello_world_fixed_parms: |
| function: src/hello.js |
| inputs: |
| name: Sam |
| place: the Shire |
| ``` |
| |
| ### Deploying |
| ```sh |
| $ wskdeploy -m docs/examples/manifest_hello_world_fixed_parms.yaml |
| ``` |
| |
| ### Invoking |
| ```sh |
| $ wsk action invoke hello_world_package/hello_world_fixed_parms --blocking |
| ``` |
| |
| ### Result |
| The invocation should return an 'ok' with a response that includes this result: |
| ```json |
| "result": { |
| "greeting": "Hello, Sam from the Shire" |
| }, |
| ``` |
| |
| ### Discussion |
| |
| In this example: |
| - The value for the ‘```name```’ input parameter would be set to “```Sam```”. |
| - The value for the ‘```place```’ input parameter would be set to “```the Shire```”. |
| - The wskdeploy utility would infer that both ‘```name```’ and ‘```place```’ input parameters to be of type ‘```string```’. |
