The interceptor service REST API is added using swagger definition file which generates the Synapse API configuration file in Micro Integrator.

To learn about interceptors and for instructions on how to run it please head over to the home directory of interceptor samples.

Prerequisites

• WSO2 Integration Studio 8.1.0
• Docker
• Java 11

Build the sample from source

1. First you need to copy the required certs

   ./copy-certs.sh

   Here, the requestBody is Base64 encoded.

2. Then, Open the InterceptorServiceWithMI project to Integration Studio. You can view the sample service configuration in following file.

   /InterceptorServiceWithMIConfigs/src/main/synapse-config/api/Choreo-Connect_Interceptor_Service.xml
   

3. Next, In the project explorer window, right click on InterceptorServiceWithMIDockerExporter and select Build Docker Image option. This will create the docker image we want to run.

4. Start the interceptor service.

   docker run --name interceptor-wso2-mi -p 9081:8253 wso2am/cc-sample-xml-interceptor-wso2-mi:v1.0.0

5. Test the interceptor service.

   curl https://localhost:9081/api/v1/handle-request \
      -H "content-type: application/json" \
      -H "accept: application/json" \
      -d '{"requestBody": "eyJuYW1lIjoiVGhlIFByaXNvbmVyIn0K"}' \
      --cert ../resources/certs/mg.pem \
      --key ../resources/mg.key \
      --cacert ../resources/certs/interceptor.pem

   Sample response

   { "headersToAdd": { "x-user": "admin" }, "headersToReplace": { "content-type": "application/xml" }, "body": "PG5hbWU+VGhlIFByaXNvbmVyPC9uYW1lPg==" }
   

   curl https://localhost:9081/api/v1/handle-response \
      -H "content-type: application/json" \
      -H "accept: application/json" \
      -d '{"responseCode": 200}' \
      --cert ../resources/certs/mg.pem \
      --key ../resources/mg.key \
      --cacert ../resources/certs/interceptor.pem

   Sample response

   { "responseCode": 201 }
