I am new to api gateways and I wanted to try to use Tyk product I installed the docker version and created an api using the documentation
I tried to do a transformation using templates but the request was forwarded without any transformation
here is the Api configuration
{
"name": "Hello-World",
"slug": "hello-world",
"api_id": "Hello-World",
"org_id": "1",
"use_keyless": true,
"auth": {
"auth_header_name": "Authorization"
},
"definition": {
"location": "header",
"key": "x-api-version"
},
"version_data": {
"not_versioned": true,
"versions": {
"Default": {
"name": "Default",
"use_extended_paths": true
},
"extended_paths": {
"transform": [
{
"path": "/widgets",
"method": "POST",
"template_data": {
"template_mode": "file",
"template_source": "./templates/transform_test.tmpl"
}
}
]
}
}
},
"proxy": {
"listen_path": "/widgets",
"target_url": "http://7857-102-158-57-156.ngrok.io/api/v1",
"strip_listen_path": true
},
"active": true
}
The target_url is pointing to dummy express service that responds with the request body.
here is the template I am using
{
"value1": "{{.value2}}",
"value2": "{{.value1}}",
"transformed_list": [
{{range $index, $element := .value_list}}
{{if $index}}
, "{{$element}}"
{{else}}
"{{$element}}"
{{end}}
{{end}}
]
}
and this is the input I am trying to transform
{
"value1": "value-1",
"value2": "value-2",
"value_list": [
"one",
"two",
"three"
]
}
