如何使用Cloud Function和Mail API接收，处理和发送电子邮件？

Question

I am trying to create a basic application to do the following using GCP:

1. Receive an email
2. Read the email
3. Process the text in the email body
4. Send the processed text to the original sender as email body

For example:

example@example.com sends an email with Subject Process this and Email body Hello to the Google service account . The python program ( Cloud functions ) will programmatically read the email body as string, append world! , then send Hello world! to the example@example.com as email body with subject Processed! .

I have added example@example.com to Mail API Authorised Senders .

I found these GitHub code to send and receive email.

How do I use these in cloud functions to actively look for incoming email and respond with a appropriate email with respect to my process?

Answer 1

As I understand your problem is that you don't know how to trigger you Cloud Function. In this case I would suggest you to read Google's documentation about calling a Cloud Function .

In your case, you could use this Third Party API . What this API does is when you receive an e-mail, it sends an HTTP POST request with all the information that are included in the e-mail. This HTTP request will trigger your function.

Let me know if it was helpful.
