352 +== **1.8 How to parse value from HTTP response body** ==
353 +
354 +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":
355 +
356 +(% style="text-align:center" %)
357 +[[image:InputHTTPparameter.png]]
358 +
359 +Then the response body would be like as following:

418 + print("code:"..code)
419 + if code~= 200 then
420 + return
421 + else
422 + return result_table
423 + end
424 +end
425 +
426 +function sendAPI(key, city)
