How to use

Simple request

Create .yml file with request description:

method: get
url: http://host.com/

then pass file path to desman

desman path/to/file.yml

and desman prints the body of response to console.

Request with parameters

Query parameters can be passed in url

method: get
url: http://host.com/?param=value

or be passed separately

method: get
url: http://host.com/
params:
  param: value

Headers

Headers can be passed in headers field

method: get
url: http://host.com/
headers:
  Authorization: Bearer some-auth-token
params:
  param: value

Body

Body content can be passed in body field in request file

method: post
url: http://host.com/post
headers:
  Authorization: Bearer some-auth-token
body: |
  {
      "stringField": "JSON value",
      "nestedObject": {
          "nestedField": [1, 2, 3]
      }
  }

Output parameters

The output of HTTP response is controlled by these optional paramters:

• -s print status of response
• -H print heafers of response
• -b print body of response

If none of these parameters are passed desman prints only body of response.

Using environments

All request files are Jinja2 templates.

# request.yml
method: post
url: http://{{server.host}}:{{server.port}}/post
headers:
  Authorization: Bearer {{my-token}}
body: |
  {
      "stringField": "JSON value",
      "nestedObject": {
          "nestedField": [1, 2, 3]
      }
  }

Variables are substituted from enviroment .yml files

# env.yml
server:
  host: host.com
  port: 8080
my-token: "some-auth-token"

which are passed in optional parameter -e

desman -e env.yml request.yml

You can use many enviroment files. If they have similar fields desman will use the last occurence of value.

With many enviroment files

# env.yml
server:
  host: host.com
  port: 8080
my-token: "some-auth-token"

# new-token.yml
my-token: "new-token"

if both passed as

desman -e env.yml -e new-token.yml request.yml

request will be performed with Authorization: Bearer new-token header.
