Indlela ye-HTTP GET yengeza iyunithi yezinhlamvu yombuzo ekugcineni kwe-URL ukuze ithumele idatha kuseva. Iyunithi yezinhlamvu yombuzo isesimweni sepheya key=value kwandulelwa uphawu ? .

Kusuka ku-URL, iseva ingakwazi ukuhlaziya inani elithunyelwe umsebenzisi lapho:

• ukhiye - indawo
• inani -Italy
