Patent number: 10904316Abstract: Data processing method and apparatus in a Service-Oriented architecture (SOA) system are disclosed. The method replaces a target parameter having a larger data length included in an original HTTP request with an intermediate parameter having a smaller data length. A data length of a HTTP request that is converted from an original HTTP request is reduced as compared to a data length of the original HTTP request, thus reducing an amount of data that is transmitted, i.e., sent or received, by a target component, which accordingly reduces an amount of data transmitted in the SOA system and decreases a network overhead of the SOA system.Type: GrantFiled: May 20, 2019Date of Patent: January 26, 2021Assignee: Alibaba Group Holding LimitedInventor: Xikui Zhang
