Hello. I am using WireMock (not WireMock Cloud) in standalone on a docker. So I configure my mappings via JSON files. Is it possible to use each, and conditions, in the JSON to make it dynamic ? (eg : I receive an array of X element, so I return another array of X elements) I struggle to find documentation of response templating for WireMock standalone on docker. Thanks !

Hi Victor, the templating language is the same regardless of which edition so everything in https://wiremock.org/docs/response-templating/ applies. The

each

,

if

and other conditional helpers are all available.

Hi Tom thanks for this quick answer. It seems that I was missing the ""transformers": ["response-template"]". However when I am trying to do something slightly more complicated than just a single if, when I do it on, several lines, I have issues on startup : "Illegal unquoted character ((CTRL-CHAR, code 13)): has to be escaped using backslash to be included in string value". Do I need to set an option to allow "coding" on several lines ?"

No, you shouldn't need that. If you post the code you're trying to implement I might be able to see what's wrong.

{

"request": {

"method": "GET",

"url": "/conditional/stuff"

},

"response": {

"status": 200,

"body": "{{#if (contains 'abcde' 'abc')}}

YES

{{/if}}",

"transformers": ["response-template"],

"headers": {

"Content-Type": "text/json"

}

}

}

As simple as that 🙂 When runing the docker I get :

Yeah, it looks like you’ve got some UTF16 characters in there maybe?

So I have to keep all my "code" in a single line... =(

This is standard JSON unfortunately, not a lot we can do about that. We have a PR open to expand to JSON5 and another to add YAML support so these will help in cases like this.

I'll be happy to define it using something else. My needs are for it to be easy and simple. A docker running with files in the mapping folder. I don't wan't to create a java app for this mock

Do you know you can also extract the response body to its own file?

Yeah I think I read that but in this extracted file, I won't be able to have multi-line right ?

So you create a file called e.g.

my-response-body.json

under

__files

then reference it

"bodyFileName": "my-response-body.json"

in your stub instead of

body

What I need is to have some "complicated" stuff like :

"body": "[ {{#each (jsonPath request.body '$') as |todo|}}
                  { \"todo_id\":
                      {{#if (todo.todo_id == null) }}
                          1{{randomValue length=1 type='NUMERIC'}}
                      {{else}}
                          {{todo.todo_id}}
                      {{/if}}
                },
            {{/each}} ]"

On multi-line so it can be on source control, and be reviewed

Then you can format the body however you like

Can I really format it the way I want ? is is still a json "my-response-body*.json*"

Yes, although it can be whatever format you’re using

I'm in a meeting rn but I'll give that a try after 🙂 thanks !

The

Content-Type

response header is what actually determines the type, as far as your calling client is concerned

Yep it works ! thanks for that, it is not perfect, but it will definitly cover my needs

No probs 👍
