353 +== **1.8 How to parse value from HTTP response body** ==
354 +
355 +This example use [[https:~~/~~/www.weatherapi.com/>>https://www.weatherapi.com/]] as example, to show how to parse value from HTTP response body. When we input the city name into address "@HDW5050":
356 +
357 +(% style="text-align:center" %)
358 +[[image:InputHTTPparameter.png]]
359 +
360 +Then the response body would be like as following:

420 + if code~= 200 then
421 + return
422 + else
423 + return result_table
424 + end
425 +end
