HTTPRequest

Hello,

I try to read data from the openweathermap.org. Have good results with python.
I use this simple python code:

Code: Select all

# Enter your API key here 
api_key = "e8b010e1ab578d6426ad5a9359f636c1"

# base_url variable to store url 
base_url = "http://api.openweathermap.org/data/2.5/weather?"

# Give city name 
#city_name = input("Enter city name : ") 
city_name = "hellevoetsluis"

# complete_url variable to store 
# complete url address 
complete_url = base_url + "appid=" + api_key + "&q=" + city_name


# get method of requests module 
# return response object 
response = requests.get(complete_url)
I try the same in Purebasic with no results.
This is the code:

Code: Select all

;
; ------------------------------------------------------------
;
;   PureBasic - Call OpenWeathermap.org
; 
;   http://api.openweathermap.org/Data/2.5/weather?appid=e8b010e1ab578d6426ad5a9359f636c1&q=hellevoetsluis
;

InitNetwork()

HttpRequest = HTTPRequest(#PB_HTTP_Get, "http://api.openweathermap.org/Data/2.5/weather?appid=e8b010e1ab578d6426ad5a9359f636c1&q=hellevoetsluis")  
If HttpRequest
    Debug "StatusCode: " + HTTPInfo(HTTPRequest, #PB_HTTP_StatusCode)
    Debug "Response: " + HTTPInfo(HTTPRequest, #PB_HTTP_Response)
    
    FinishHTTP(HTTPRequest)
  Else
    Debug "Request creation failed"
  EndIf
What is wrong with the Purebasic code?
Thanks for any help.

Their URL is case-sensitive.

'data' got changed to 'Data' ***

Change it back to '/data/' and it works fine.


*** I'm guessing it got changed by the IDE's aggressive case correction (Data is a keyword) which I would like to change now that the IDE is open source :)

found a small bug:

Code: Select all

Structure OWMWeatherStructure_hourly
  dt.i
  sunrise.i
  sunset.i
  temp.f
  feels_like.f
  pressure.i
  humidity.i
  dew_point.f
  uvi.f
  clouds.i
  visibility.i
  wind_speed.f
  wind_deg.i
  weather.OWMWeatherList
  pop.f
EndStructure
should be

Code: Select all

Structure OWMWeatherStructure_hourly
  dt.i
  sunrise.i
  sunset.i
  temp.f
  feels_like.f
  pressure.i
  humidity.i
  dew_point.f
  uvi.f
  clouds.i
  visibility.i
  wind_speed.f
  wind_deg.i
  List weather.OWMWeatherList()
  pop.f
EndStructure

I found not bug, but issue with name of one value in OWM JSON. In alert is one value named as reserved word end. Is way to solve it?

The only trick I know:

Code: Select all

JSON$ = ReplaceString(JSON$, #DQUOTE + "end" + #DQUOTE, #DQUOTE + "_end" + #DQUOTE)
All times are UTC+01:00
