WSO2 APIM API调用错误(WSO2 APIM API invocation error)

WSO2 APIM API调用错误(WSO2 APIM API invocation error)

我已经建立了WSO2 API Manager并设置了一个API。 试图通过APIM console本身调用它，但它表示没有来自客户端的响应。

我启用了log4j.logger.org.apache.synapse.transport.http.wire=DEBUG并在wso2-apigw-errors.log发现了以下错误。

有人可以帮忙吗？

I have set up WSO2 API Manager and set up an API. Tried to invoke it via APIM console itself .But it says NO response from client.

I enabled log4j.logger.org.apache.synapse.transport.http.wire=DEBUG and found out the below error in the wso2-apigw-errors.log.

Can someone please help?

最满意答案

根据最后一条评论，我相信您的问题将通过尝试连接到端点时在错误中给出的答案解决。 不能借用ssl的客户端

As per the last comment, I believe your issue will be fixed by the answer given in Error while trying to connect to the endpoint. Cannot borrow client for ssl
