MicrosoftLearnをやってみました。これめちゃ便利ですね。

curlでのテスト

yuta@DESKTOP-V36210S:/mnt/c$ curl -X POST -H "Content-Type: application/json" -d '{"name":"Azure"}' https://escalator-functions-0910.azurewebsites.net/api/HttpTrigger1?code=81yzkMKApPA4AvZwRvWvwS9B0WMFANwdaODJhieNZH4Ca2/IZk4eHQ==

index.jsを更新する

module.exports = function (context, req) {
    context.log('Drive Gear Temperature Service triggered');
    if (req.body && req.body.readings) {
        req.body.readings.forEach(function(reading) {

            if(reading.temperature<=25) {
                reading.status = 'OK';
            } else if (reading.temperature<=50) {
                reading.status = 'CAUTION';
            } else {
                reading.status = 'DANGER'
            }
            context.log('Reading is ' + reading.status);
        });

        context.res = {
            // status: 200, /* Defaults to 200 */
            body: {
                "readings": req.body.readings
            }
        };
    }
    else {
        context.res = {
            status: 400,
            body: "Please send an array of readings in the request body"
        };
    }
    context.done();
};

次のBodyでPOSTする

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