Я играю с WSO2 API Manager, и мне было интересно, как позаботиться о следующем сценарии:
Я создал REST API и включил в него токен JWT. При вызове API, если я не передаю токен, я получаю сообщение об ошибке, но в формате XML. Мне было интересно, как и где мы можем изменить это на JSON формат.
<ams:fault xmlns:ams="http://wso2.org/apimanager/security">
<ams:code>900901</ams:code>
<ams:message>Invalid Credentials</ams:message>
<ams:description>Access failure for API: /employee/1.0.0, version: 1.0.0 status: (900901) - Invalid Credentials. Make sure you have provided the correct security credentials</ams:description>
</ams:fault>
Обновление:
Я перешел к настройке времени выполнения и попытался обновить Посредничество сообщений в разделе сбоя до JSON Ошибка, но при сохранении я вижу следующее исключение. Ошибка не меняется.

, ссылаясь на эту операцию c, я смог получить сообщение в формате JSON https://docs.wso2.com/display/AM260/Error+Handling
Обновление 3:
Теперь, как я могу изменить структуру полезной нагрузки?
Ну, что я действительно хочу, это изменить
{ "fault": { "code": 900901, "message": "Invalid Credentials", "description": "Access failure for API: /employee/1.0.0, version: 1.0.0 status: (900901) - Invalid Credentials. Make sure you have provided the correct security credentials" }}
полезная нагрузка сообщения по умолчанию на что-то вроде этого
