1: Use httpRequest.js to make a http call.
var httpWrapper = require('httpRequest')
httpWrapper.httpGet(query, (theResult) => {
console.log(theResult)
});
2: Query dynamo DB and send results in response .
Run aws-read-dynamo.js to fetch data db . replace YOUR_TABLE_NAME and YOUR_COLOUMN_VALUE with your database fields.
var params = {
TableName: "YOUR_TABLE_NAME",
KeyConditionExpression: "#Labels = :Labels",
ExpressionAttributeNames: {
"#Labels": "Labels"
},
ExpressionAttributeValues: {
":Labels": "YOUR_COLOUMN_VALUE"
}
};
3: Use aws-rekognition-sample.js to detect image uploaded by a post request .
this sample accepts post request with a base64 string under photoBase key.in response you will receive detected values in json.
var params = {
"Body": decodedImage,
"Bucket": "YOUR_BUCKET_NAME",
"Key": photoPath
};
Because this uploads image to s3 as well ,replace YOUR_BUCKET_NAME with your cerated bucket name .
PS: Lambda will need necessary permission to access resources .above all samples assumes permission has been granted.
