Hi Royer, Alexis,

Thank you for reaching out to Microsoft Q & A forum. 

It looks like the issue may be due to a missing or incorrect function key or function URL. Please check the following: 

1.Function Key: Make sure your function key is included in the x-functions-key header. You can find it in the Azure Portal under: 

Function App > Your Function > Function Keys. 

2.Function URL: Ensure you're using the correct function URL by navigating to: 

Azure Portal > Function App > Your Function > Get Function URL. 

Once you've verified these details, try running the following command with the correct values: 

curl --header "Content-Type: application/json" \
     --header "x-functions-key: YOUR_ACTUAL_FUNCTION_KEY" \
     --request POST \
     --data '{"name": "Azure Function"}' \
     YOUR_ACTUAL_FUNCTION_URL

Additionally, you can check the Logs under Code + Test in the Azure Portal to see if the request is being received.

Answer 2

Hi Royer, Alexis,

Thank you for your message. I see that you're encountering issues when trying to pass the name variable to your function via the curl command. 

Based on your command and the details you’ve provided; it seems that the issue may be due to a few key points: 

1.Correct curl Command Syntax: It looks like there was a minor issue with the syntax in your curl command. The correct version should wrap the URL in quotes, like this: 

curl --header "Content-Type: application/json" --header "x-functions-key: roZ1JivKlhsHJcxB0c7Nz3pyNBB8-axVbgFrT_jNmsf_AzFudcfaTA==" --request POST --data "{\"name\": \"Azure Function\"}" "https://RoyerAlexisfunction.azurewebsites.net/api/DriveGearTemperatureService?code=C1tpMcg6fIf-dhUgDhG0HXlGbKD1TLhH6WkuC68ariZxAzFuhSOKnw%3D%3D"

Notice the quotes around the entire URL — this ensures the command executes properly in the terminal. 

2.JSON Format: Ensure that you're sending the correct JSON payload in the request body. For your exercise, the payload you're passing should look like this: 

{
    "Readings": [
        {
            "driveGearId": 1,
            "timestamp": 1534263995,
            "temperature": 23
        },
        {
            "driveGearId": 3,
            "timestamp": 1534264048,
            "temperature": 45
        },
        {
            "driveGearId": 18,
            "timestamp": 1534264050,
            "temperature": 55
        }
    ]
}

  

This JSON data should be included in the body of the curl request. It seems that you might have missed adding this in your previous attempt. 

3.Valid Function Key: Ensure that you're using the correct function key in the x-functions-key header. This key should be valid and match the one generated by your Azure Function app. 

Once you update your curl command with the correct syntax and the proper JSON data in the body, the function should be able to process the incoming request and pass the name variable correctly.
