在这里,我的控制器操作端点有一个有效负载:
%{
"mandrill_events" => "[{\"event\":\"send\",\"msg\":{\"ts\":1365109999,\"subject\":\"This an example webhook message\",\"email\":\"example.webhook@mandrillapp.com\",\"sender\":\"example.sender@mandrillapp.com\",\"tags\":[\"webhook-example\"],\"opens\":[],\"clicks\":[],\"state\":\"sent\",\"metadata\":{\"user_id\":111},\"_id\":\"exampleaaaaaaaaaaaaaaaaaaaaaaaaa\",\"_version\":\"exampleaaaaaaaaaaaaaaa\"},\"_id\":\"exampleaaaaaaaaaaaaaaaaaaaaaaaaa\",\"ts\":1518203456},{\"event\":\"send\",\"msg\":{\"ts\":1365109999,\"subject\":\"This an example webhook message\",\"email\":\"example.webhook@mandrillapp.com\",\"sender\":\"example.sender@mandrillapp.com\",\"tags\":[\"webhook-example\"],\"opens\":[],\"clicks\":[],\"state\":\"sent\",\"metadata\":{\"user_id\":111},\"_id\":\"exampleaaaaaaaaaaaaaaaaaaaaaaaaa1\",\"_version\":\"exampleaaaaaaaaaaaaaaa\"},\"_id\":\"exampleaaaaaaaaaaaaaaaaaaaaaaaaa1\",\"ts\":1518203456}]"
}
我正在尝试解码 的内容mandrill_events
,以便我可以访问一些值,但我认为括号将其丢弃。
get_in(payload, ["mandrill_events"]) |> Base.url_decode64 |> Poison.decode!
但这也没有用。
