Based on this information, Dubbo Admin renders the parameters into the Json Editor of the service test page, where the user enters the values of each parameter and each member variable.</p><h2 id=principle-generalized-calls>Principle: Generalized calls</h2><p>With the parameter type, the next question is how to call to the server. In the traditional Dubbo RPC call, the client needs to rely on the server’s API jar package ( refer to the <a href=https://github.com/nzomkxia/dubbo-demo/tree/master/dubbo-basic-consumer>dubbo-basic-consumer</a> in the previous demo ), which is unlikely for Dubbo Admin, because the up and down of services are dynamic, Dubbo Admin can not dynamically increase the jar package dependencies, so you need to use the <strong>generalization call</strong> in Dubbo , which means that in the absence of the server API interface, the client initiates a service call through the <code>GenericService</code> interface, and the data objects in return values are represented by maps. The generalization call doesn’t require special processing on the server side, only need to be initiated by the client side.</p><h2 id=summary-and-outlook>Summary and outlook</h2><p>This article briefly introduces the usage and principle of service testing, and will further enhance this function in the future, such as processing the parameter types of abstract classes, importing parameter values from json files, supporting the saving of parameter values, etc., to facilitate regression testing of the service interface.</p><ul class="list-unstyled d-flex justify-content-between align-items-center mb-0 pt-5"><li><a href=/en/blog/2019/08/11/tracing-dubbo-service-with-apache-skywalking/ aria-label="Previous - Tracing Dubbo service with Apache Skywalking" class="btn btn-primary"><span class=mr-1>←</span>Previous</a></li><li><a href=/en/blog/2022/01/18/makes-it-more-convenient-for-you-to-proxy-dubbo-services-in-apache-apisix/ aria-label="Next - Makes it More Convenient for You to Proxy Dubbo Services in Apache APISIX" class="btn btn-primary">Next<span class=ml-1>→</span></a></li></ul></div><div id=pre-footer><h2>Feedback</h2><p class=feedback--prompt>Was this page helpful?</p><button class="btn btn-primary mb-4 feedback--yes">Yes</button> |
