c# - 将订阅者添加到ASP.NET的Mail Chimp 3.0中的列表中

我正在尝试使用ASP.NET C#网站实现Mail Chimp的新API，因此，当用户在输入框中输入其电子邮件地址时，它将自动添加到我的mailchimp列表中。我尝试了其他各种方法，但是这些方法均无效。

我尝试了一个Web客户端，该客户端抛出405无法使用该方法响应，而一个HttpClient则对加星标的GetStringAsync方法调用抛出了错误，因为它不是一项任务。

到目前为止，我的代码如下:

public bool BatchSubscribe(IEnumerable<MailChimpSubscriberModel> newSubscribers)
{
    if (string.IsNullOrEmpty(_defaultListId)) throw new ArgumentNullException(Res.Resource.MailChimpIntegrationNoListId);

    if (string.IsNullOrEmpty(_apiKey)) throw new ArgumentNullException(Res.Resource.MailChimpIntegrationNoApiKey);

    foreach (MailChimpSubscriberModel subscriber in newSubscribers)
    {
        string url = "https://" + _dataPoint + ".api.mailchimp.com/3.0/lists/" + _defaultListId + "/";

        Subscriber member = new Subscriber();
        member.email = subscriber.Email;
        member.subscribed = "subscribed";

        string jsonString = new JavaScriptSerializer().Serialize(member);

        //using (WebClient client = new WebClient())
        //{
        //    client.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
        //    client.Headers[HttpRequestHeader.Authorization] = new AuthenticationHeaderValue("Basic", _apiKey).ToString();
        //    string HtmlResult = client.(url, jsonString);

        //    return true;
        //}

        using (var http = new HttpClient())
        {
            http.DefaultRequestHeaders.Authorization =
                 new AuthenticationHeaderValue("Basic", _apiKey);
            string content = await http.**GetStringAsync**(@"https://us11.api.mailchimp.com/3.0/lists");
            Console.WriteLine(content);
        }
    }
    return false;
}

最佳答案

我对这个问题有点晚了，但是花了我半天的时间才弄清楚，这里有我的答案，因此可以为他人提供帮助。我正在使用MailChimp 3.0:

private void subscribeAddress()
{
  string apiKey = "APIKEY-usX"; //your API KEY created by you.
  string dataCenter = "usX";
  string listID = "listID"; //The ListID of the list you want to use.

  SubscribeClassCreatedByMe subscribeRequest = new SubscribeClassCreatedByMe
  {
      email_address = "[email protected]",
      status = "subscribed"
  };
  subscribeRequest.merge_fields = new MergeFieldClassCreatedByMe();
  subscribeRequest.merge_fields.FNAME = "YourName";
  subscribeRequest.merge_fields.LNAME = "YourSurname";

  using (HttpClient client = new HttpClient())
  {
      var uri = "https://" + dataCenter + ".api.mailchimp.com/";
      var endpoint = "3.0/lists/" + listID + "/members";

      client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", apiKey);
      client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
      client.BaseAddress = new Uri(uri);

      //NOTE: To avoid the method being 'async' we access to '.Result'
      HttpResponseMessage response = client.PostAsJsonAsync(endpoint, subscribeRequest).Result;//PostAsJsonAsync method serializes an object to
                                                                                            //JSON and then sends the JSON payload in a POST request
    //StatusCode == 200
    // -> Status == "subscribed" -> Is on the list now
    // -> Status == "unsubscribed" -> this address used to be on the list, but is not anymore
    // -> Status == "pending" -> This address requested to be added with double-opt-in but hasn't confirmed yet
    // -> Status == "cleaned" -> This address bounced and has been removed from the list

    //StatusCode == 404
    if ((response.IsSuccessStatusCode))
    {
       //Your code here
    }
  }
}

这里有类SubscribeClassCreatedByMe和MergeFieldClassCreatedByMe

namespace Subscriber
{
  public class SubscribeClassCreatedByMe
  {
    public string email_address { get; set; }
    public string status { get; set; }
    public MergeFieldClassCreatedByMe merge_fields { get; set; }
  }
}
namespace Subscriber
{
  public class MergeFieldClassCreatedByMe
  {
    public string FNAME { get; set; }
    public string LNAME { get; set; }
  }
}

好吧，希望能对您有所帮助!!
