如何在 Rails 中使用 Mailgun 和 HTTParty

Question

我想在 Rails 中將 Mailgun 與 HTTParty 結合使用：

RestClient.post "https://api:key-###"\
    "@api.mailgun.net/v3/###/messages",
    from: from_email,
    to: to_email,
    subject: title,
    html: body_text

它的工作，但

payload = {
    from: email_history.from_email,
    to: email_history.to_email,
    subject: email_history.title,
    html: email_history.body_text,
    multipart: true
}

response = SendEmailJob.post('https://api:key-###'\
'@api.mailgun.net/v3/###/messages', payload)

退貨：

{
  "message": "'from' parameter is missing"
}

我檢查過，有效負載“from”參數存在。

我怎樣才能解決這個問題？

我通過添加正文解決了這個問題：

SendEmailJob.post('api:key-###'\ '@api.mailgun.net/v3/###/messages', body: payload)
