email driven image upload on imgur

Question

I've gone through the class as you stated in github and I've added one more field in the class to get the attachment value from the email. here is the required class for mandrill webhook.

using System.Collections.Generic;
using Newtonsoft.Json;

namespace Mandrill
{
public class MailEvent
{
    [JsonProperty(PropertyName = "ts")]
    public string TimeStamp { get; set; }

    [JsonProperty(PropertyName = "event")]
    public string Event { get; set; }

    [JsonProperty(PropertyName = "msg")]
    public Message Msg { get; set; }
}

public class Message
{
    [JsonProperty(PropertyName = "raw_msg")]
    public string RawMessage { get; set; }

    [JsonProperty(PropertyName = "headers")]
    public Header Header { get; set; }

    [JsonProperty(PropertyName = "text")]
    public string Text { get; set; }

    [JsonProperty(PropertyName = "html")]
    public string Html { get; set; }

    [JsonProperty(PropertyName = "from_email")]
    public string FromEmail { get; set; }

    [JsonProperty(PropertyName = "from_name")]
    public string FromName { get; set; }

    // Not sure why Mandrill sends an array of arrays here...
    [JsonProperty(PropertyName = "to")]
    public string[][] To { get; set; }

    [JsonProperty(PropertyName = "email")]
    public string Email { get; set; }

    [JsonProperty(PropertyName = "subject")]

    [JsonProperty(PropertyName = "spf")]
    public SPF SPF { get; set; }

    [JsonProperty(PropertyName = "spam_report")]
    public SpamReport SpamReport { get; set; }

    //[JsonProperty(PropertyName = "attachments")]
    //public attachments attachments { get; set; }

    [JsonProperty(PropertyName = "attachments")]
    public IDictionary<string, IDictionary<string,string>> attachments { get; set; }
}

[JsonDictionary()]
public class Header : Dictionary<string, object>
{
    // Need to find a nicer way of doing this... Dictionary<string, object> is kinda dumb
}

public class attachments
{
    [JsonProperty(PropertyName = "name ")]
    public string name { get; set; }

    [JsonProperty(PropertyName = "type ")]
    public string type { get; set; }

    [JsonProperty(PropertyName = "content ")]
    public string content { get; set; }

    [JsonProperty(PropertyName = "base64 ")]
    public bool base64 { get; set; }
}

public class SpamReport
{
    [JsonProperty(PropertyName = "score")]
    public decimal Score { get; set; }

    [JsonProperty(PropertyName = "matched_rules")]
    public SpamRule[] MatchedRules { get; set; }
}

public class SpamRule
{
    [JsonProperty(PropertyName = "name")]
    public string Name { get; set; }

    [JsonProperty(PropertyName = "score")]
    public decimal Score { get; set; }

    [JsonProperty(PropertyName = "description")]
    public string Description { get; set; }

    [JsonProperty(PropertyName = "result")]
    public string Result { get; set; }

    [JsonProperty(PropertyName = "detail")]

}

and you have to call the imgur api like this.

[HttpPost]
    [ValidateInput(false)]
    public ActionResult past_mandrill(FormCollection fc)
    {

        string json = fc["mandrill_events"];

        //SqlConnection con = new SqlConnection(WebConfigurationManager.AppSettings[0]);
        var events = JsonConvert.DeserializeObject<IEnumerable<Mandrill.MailEvent>>(json);

        foreach (var mailEvent in events)
        {
            //Label2.Text = Label2.Text + mailEvent.Msg.To[0][0] + "<br>";
            try
            {

                foreach (KeyValuePair<string, IDictionary<string, string>> attch in mailEvent.Msg.attachments)
                {
                    //Label2.Text = Label2.Text + attch.Key + "<br>";
                    byte[] temp;
                    string albumid = "zBBCDbRcNhE493I"; //use your own album id where you want to store the image.
                    foreach (KeyValuePair<string, string> attchcnt in attch.Value)
                    {
                        //Label2.Text = Label2.Text + attchcnt.Key + "  " + attchcnt.Value + "<br>";

                        if (attchcnt.Key.Equals("content"))
                        {
                            using (var w = new WebClient())
                            {

                                string base64String = "";
                                base64String = attchcnt.Value.ToString();
                                var values = new NameValueCollection
                            {
                                {"image",  base64String},
                                {"album", albumid}
                            };

                                w.Headers.Add("Authorization", "Client-ID dac37a6b08b4974"); // user your own client-id of imgur website
                                byte[] response = w.UploadValues("https://api.imgur.com/3/upload.xml", values);
                                temp = response;

                            }
                        }


                    }

                }
            }
            catch (Exception e)
            {
            }

            //Label2.Text = mailEvent.Msg.attachments.Values.ToString();



        }


        return new HttpStatusCodeResult((int)HttpStatusCode.OK);
    }
