(For the complete version of this question, please refer to https://social.msdn.microsoft.com/Forums/en-US/20bb5b37-82af-4cf3-8a59-04e5f19572bc/send-email-to-multiple-recipients-using-sendgrid-failure?forum=AzureFunctions)
Sending to single recipient was successful. But found no way to send to multiple recipients or CC/BCC in Azure function.
Tried several formats including
{ "to": [{ "email": ["[email protected]", "[email protected]" ] }] }
It seemed to be the limit from azure function. But not sure where goes wrong yet. Please refer to the "bindings" below,
{
"bindings": [
{
"name": "telemetryEvent",
"type": "serviceBusTrigger",
"direction": "in",
"queueName": "threshold-email-queue",
"connection": "RootManageSharedAccessKey_SERVICEBUS",
"accessRights": "Manage"
},
{
"type": "sendGrid",
"name": "$return",
"apiKey": "SendGridKey",
"direction": "out",
"from": "[email protected]",
"to": [{
"email": ["[email protected]", "[email protected]" ]
}]
}
],
"disabled": false
}
Thanks to Tamás Huj, the function can do the job now. So I post the solution in detail for others reference.
{
"bindings": [
{
"name": "telemetryEvent",
"type": "serviceBusTrigger",
"direction": "in",
"queueName": "threshold-email-queue",
"connection": "RootManageSharedAccessKey_SERVICEBUS",
"accessRights": "Manage"
},
{
"type": "sendGrid",
"name": "$return",
"apiKey": "SendGridKey",
"direction": "out",
"from": "[email protected]"
}
],
"disabled": false
}
Then write the run.csx as:
#r "SendGrid"
#r "Newtonsoft.Json"
using System;
using SendGrid.Helpers.Mail;
using System.Threading.Tasks;
using Microsoft.Azure.WebJobs.Host;
using Newtonsoft.Json;
public static Mail Run(string telemetryEvent, TraceWriter log)
{
var telemetry = JsonConvert.DeserializeObject<Telemetry>(telemetryEvent);
Mail message = new Mail()
{
Subject = "Write your own subject"
};
var personalization = new Personalization();
personalization.AddBcc(new Email("[email protected]"));
personalization.AddTo(new Email("[email protected]"));
//add more Bcc,cc and to here as needed
Content content = new Content
{
Type = "text/plain",
Value = $"The temperature value is{temperature.Temperature}."
};
message.AddContent(content);
message.AddPersonalization(personalization);
return message;
}
public class Telemetry
{
public float Temperature { get; set; }
}
