Calculate a driving route between two coordinates

[sophie]

I want to Import Routing with OSRM in MIT App Inventor.I have the url i want to insert "https://router.project-osrm.org/route/v1/driving/22.935271,40.640063;22.948055,40.629269?overview=false&alternatives=false&steps=true" and i think i should do it with web component to call this url. This URL will calculate a driving route between two coordinates.Can anyone help me build this block so as this works?.
While asking chatgpt it says that i have to Add Components to Input Coordinates

Add two TextBox components for the user to input starting and destination coordinates (or use a LocationSensor for the device’s current location).

• Add a Button to trigger the routing process.

5. Configure Blocks to Get the Route

In the Blocks Editor, you’ll set up logic to:

• Send a GET request to the OSRM API with the start and destination points.

• Parse the JSON response and extract route details.

• Display the route on a map or provide step-by-step directions.
  Set the Web Component URL:

• When the button is clicked, update the Web1.URL property based on the coordinates entered in the TextBox components.

1. Send Web Request:

• Use the Web1.Get block to send the request.

2. Parse JSON Response:

• In the Web1.GotText event, you’ll receive the response. Use the JSONTextDecode block to parse the JSON.
• Extract route steps from the JSON. The steps field in the response will contain a list of instructions.

3. Display Directions:

• You can display the parsed directions in a Label or create a list of turn-by-turn steps.

Example Block Setup:

• On Button Click:
  • Set Web1.URL to the OSRM API URL with user inputted coordinates.
  • Call Web1.Get.
• On Web1.GotText:
  • Parse the JSON response using the JSONTextDecode block.
  • Extract the steps and display them in a Label or ListView.

Can anyone help me build this blocks ?

Thank you !

You could get the driving route using the Navigate control. The results would look similar to this example.
