如何使用云功能向 Mailchimp 活动添加新用户？

Question

我正在尝试将新用户添加到 Mailchimp 活动中。 我得到两个错误第一个说：

Function returned undefined, expected Promise or value

第二个错误的日志是：

Error: The resource submitted could not be validated. For field-specific details, see the 'errors' array.
  type: 'http://developer.mailchimp.com/documentation/mailchimp/guides/error-glossary/',
  title: 'Invalid Resource',
  status: 400,
  detail: 'The resource submitted could not be validated. For field-specific details, see the \'errors\' array.',
  instance: '549e8553-5ef1-4600-9271-07255f4673fe',
  errors: 
   [ { field: 'status',
       message: 'The value you selected is not a valid choice.' } ] }

这是我的功能

   exports.userCreated = functions.auth.user().onCreate((user) => {
    const email = user.email;
    // const displayName = user.name;

    // make Mailchimp API request to add a user
    Mailchimp
      .post('/lists/id/members', {
        email_address: email,
        status: 'Signed Up',
        // optional: requires additional setup
        merge_fields: {
          "EMAIL" : email
        }
      })
      .then(function(results) {
        console.log('Successfully added new Firebase user', email, 'to Mailchimp list',results);
      })
      .catch(function(err) {
        console.log(email);
        console.log('Mailchimp: Error while attempting to add registered subscriber —', err);
      });
  });

Answer 1

正如您所检测到的，您的云函数中有两个错误：

第一个是您必须在后台触发的 Cloud Function 中返回一个 Promise（或一个值），以向平台表明它已完成。 请观看Firebase 视频系列中关于“JavaScript Promises”的三个视频，以了解有关此关键点的更多详细信息。

第二个问题是您对字段status值“不是一个有效的选择”。 看看 Mailchimp doc ，如果我没有记错的话，正确的值是：

subscribed 、 pending 、 unsubscribed或cleaned 。

因此，以下更改应该可以解决问题：

   exports.userCreated = functions.auth.user().onCreate((user) => {
    const email = user.email;
    // const displayName = user.name;

    // make Mailchimp API request to add user
    return mailchimp
      .post('/lists/id/members', {
        email_address: email,
        status: 'subscribed',   // For example, it's up to you to find the correct status
        // optional: requires additional setup
        merge_fields: {
          "EMAIL" : email
        }
      })
      .then(function(results) {
        console.log('Successfully added new Firebase user', email, 'to Mailchimp list',results);
        return null;
      })
      .catch(function(err) {
        console.log(email);
        console.log('Mailchimp: Error while attempting to add registered subscriber —', err);
        return null;
      });
  });
