Я использую WSO2 APIManager 1.10. Я бы хотел вызвать запрос api, используя посредничество.После установки медиации в WSO2 API Manager 1.10 я выяснил исключение нулевой точки и пропущенную учетную ошибку. Что мне нужно сделать?
<sequence name="loadbalancer_bycompany" trace="disable" xmlns="http://ws.apache.org/ns/synapse">
<property expression="get-property('transport', 'company')"
name="company" scope="default" type="STRING"/>
<property name="POST_TO_URI" scope="axis2" type="STRING" value="true"/>
<switch source="$trp:company">
<case regex="sds">
<send>
<endpoint>
<address trace="disable" uri="https://70.30.182.167:8243/calc/1.0/"/>
</endpoint>
</send>
</case>
<case regex="etc">
<send>
<endpoint>
<address trace="disable" uri="https://70.30.182.167:9443/calc/1.0/"/>
</endpoint>
</send>
</case>
<default>
<send>
<endpoint>
<address trace="disable" uri="https://70.30.182.167:9443/carbon/"/>
</endpoint>
</send>
</default>
</switch>
</sequence>
Итак, я попытался установить медиатор, а затем я назвал api. Но, иногда я получал сообщение об ошибке, то есть код 900902, отсутствующий учетную запись, иногда получал правильный ответ.
В то время я нашел журналы вроде этого.

Я нашел этот журнал несколько раз, поэтому я сделал попытку исправить его. Прежде всего, чтобы удалить эту ошибку, NullPointerException SourceResponseFactory.create (SourceResponseFactory.java:64)
Я понял вопрос кода в PassThroughHttpSender.java, что не справиться с нулевым случае для sourceRequest. И затем я обнаружил, что проблема исправлена. wso2-synapse ESBJAVA-3770 Фильтрация на основе размера сообщения для предотвращения OOM. (# 679)
https://github.com/wso2/wso2-synapse/commit/1aff92c4bad968f78cf38577cbb7c01516475217
Итак, я добавил этот код в наши коды. И затем NullPointException исчез.
И затем я попытался удалить отсутствующую учетную ошибку. Итак, я нашел эту ссылку. Authorization Bearer in URL Request using WSO2 API Manager
И я попытался установить конфигурацию, как показано ниже.
https://docs.wso2.com/display/AM1100/Writing+Custom+Handlers
И тогда Отсутствующие удостоверении ошибка была удалена. И тогда результат правильный ответ. Но я нашел ниже войти бесконечно

Я пытался отладить SourceHandler и TargetHandler. , и я думаю, что соединение было создано бесконечно и не было закрыто.
Я не знаю, что делать дальше. Поэтому, пожалуйста, дайте мне знать, что я должен делать.
