| Summary: | 碩士 === 國立中興大學 === 資訊科學與工程學系 === 103 === Web Service applies as an inter-medium of product integration and functions on data exchanging in enterprise environments. But in a daily application, it is not easy to identify the real root cause of the problem. The only signal that user can know is ‘unreachable” or “disconnection”. If the failed function is built on the software A (B), the problem is passed to the maintainer of software A (B). However, the problem may not caused by software A (B), but is due to software (B) or is simply due to network disconnection. Passing the problem bindly to either the maintainer of software A or B just increase time waste and dealing difficulites on operators.
To address this issue, this thesis proposed middle-ware solution. We add an client again and a sever agent that both intercept, relay, and log requests between client and server. Through the logging mechanim, the logged database can be a traceable resouces to send GUI status code as a reference debug mechanism. This thesis also changes the visble codes on Internet into encryption code. This mechanism will be benefit to original Web Service software without modifying software codes and cover by our new safty mechamism.
