parsing json

Post by paulalsmith1000 » Thu Jan 02, 2020 8:32 pm

Evening Livecoders

I wonder if anyone could help me with the following:-

I've previously had some success importing the json response from something and then extracting the info I wanted. However, this time, to many hours has got me nowhere, so here I am again.

The request is a variation on this- https://maps.googleapis.com/maps/api/di ... dVjYr8a9Ew

All I want to do extract the distance values for each location i.e. 24m / 0.7km, but apart from the addresses everything comes back blank.

It seems to be laid out differently to last time? before so I think I must be using the wrong keys or something.

As ever any help much appreciated.

Kind regards

Paul

Hi Paul,

you could load the url and then convert it to an LC array with:

Code: Select all

...
put url("https://maps.googleapis.com/maps/api/distancematrix/json?origins=50.868376,0.251201...9Ew") into tMap
put jsontoarray(tMap) into tLCArray
... 
Then you can parse that array.
Hint:
To visualize the content of an array you can use a treeview-widget and set its "arraydata" to any array:

Code: Select all

...
put url("https://maps.googleapis.com/maps/api/distancematrix/json?origins=50.868376,0.251201...9Ew") into tMap
put jsontoarray(tMap) into tLCArray
set the arraydata of widget "you tree view widget here" to tLCArray
...
Great for understanding arrays, seeing is believing! :-)


Best

Klaus
