当我使用带有Mandrill的webhook并发布给我的Iron Worker时，我得到以下Raw（这也来自RequestBin） - 我没有包含整个有效负载，只是一个例子：
puts payload =>
mandrill_events=%5B%7B%22event%22%3A%22inbound%22%2C%22msg%22%3A%7B%22dkim%22%3A%7B%22signed%22%3Atrue%2C%22valid%22%3Atrue%7D%2C%22email%22%3A%22kaya%40hellokaya.com%22%2C%22from_email%22%3A%22example.sender%40mandrillapp.com%22%2C%22headers%22%3A%7B%22Content-Type%22%3A%22multipart%5C%2Falternative%3B+boundary%3D%5C%22_av-7r7zDhHxVEAo2yMWasfuFw%5C%22%22%2C%22Date%22%3A%22Fri%2C+10+May+2013+19%3A28%3A20+%2B0000%22%2C%22Dkim-Signature%22%3A%5B%22v%3D1%3B+a%3Drsa-
我尝试使用以下方法提取参数mandrill_events的值：
puts params = CGI::parse(@payload) =>
{"mandrill_events"=>["[{\"event\":\"inbound\",\"msg\":{\"dkim\":{\"signed\":true,\"valid\":true},\"email\":\"kaya@hellokaya.com\",\"from_email\":\"example.sender@mandrillapp.com\",\"headers\":{\"Content-Type\":\"multipart\\/alternative; boundary=\\\"_av-7r7zDhHxVEAo2yMWasfuFw\\\"\",\"Date\":\"Fri, 10 May 2013 19:28:20 +0000\",\"Dkim-Signature\":[\"v=1; a=rsa-sha1; c=relaxed\\/relaxed; s=mandrill; d=mail115.us4.mandrillapp.com; h=From:Sender:Subject:List-Unsubscribe:To:Message-Id:Date:MIME-Version:Content-Type; i=example.sender@mail115.us4.mandrillapp.com;
然后我被卡住了。我想在JSON.array中提取电子邮件值。
我想尝试以下方法;
puts json_params = JSON.parse(params)
但我现在感觉必须有更好的方法......
如何从此URL编码的字符串中提取JSON数组中的元素？
