# Revamp Mediator

A custom implementation to convert the attribute values of payloads using WSO2 Class Mediator extensions.

[Medium Story](https://medium.com/@athiththan11/wso2-class-mediators-convert-payloads-946a4fc5aa4a)

Simply put, the mediation logic will do the following conversion

```json

// original payload

{

    "post": "WSO2 Class Mediator: Revamp",

    "dev": {

        "name": "medium"

    }

}

```

to

```json

// converted

{

    "post": "WSO2 Class Mediator: Revamp",

    "dev": {

        "name": "Athiththan"

    }

}

```

## Build

Build the project by running ...

```shell

mvn clean package

```

## Deploy

After a successful build, copy the `revamp-mediator-1.0.0.jar` artifact from the `target` folder and paste it inside `/repository/components/lib` folder. And specify the deployed class mediator inside your required synapse configuration file.

For this demo, I will be using the WSO2 API Manager (2.6.0) and I will choose the `_TokenAPI_.xml` from the API Synapse Configuraitons folder (You can find your `API Synapse Configurtions` inside the `/repository/deployment/server/synapse-configs/default/api` folder), which will look as follows ...

```xml

    

        

            

            

            

                

                    

                        

                            60000

                            fault

                        

                    

                

            

        

        

            

        

    

    

        

        

    

```

Add our custom mediator inside the `inSequence` section, which will result in ...

```xml

    

        

        

        

        

    

```

## Run

Start your WSO2 API Manager server by executing the command from your `/bin` folder

```shell

sh wso2server.sh

```

or

```shell

wso2am-2.6.0

```

## Test & Results

Use the following cUrl command to invoke the `token` endpoint to examine the mediation logic

```cUrl

curl -k --header "Content-Type: application/json" --request POST --data '{"post":"WSO2 Class Mediator: Revamp","dev":{"name":"medium"}}' https:///token

```

After a successful execution, You will find the results as follows

```json

{"post":"WSO2 Class Mediator: Revamp","dev":{"name":"Athiththan"}}

```
