将订阅者添加到ASP.NET中的Mail Chimp 3.0中的列表

Question

我正在尝试使用我的ASP.NET C#网站实现Mail Chimp的新API,因此当用户将其电子邮件地址输入到输入框时,它将自动添加到我的mailchimp列表中.我尝试了其他各种方法,但这些方法都没有奏效.

我尝试过一个Web客户端,它抛出405不能使用该方法响应和一个HttpClient,它在星号GetStringAsync方法调用上引发错误,因为它不是一个任务.

我的代码到目前为止详述如下:

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;
}

我对这个问题有点迟了,但由于花了我半天的时间来弄明白,这里有我的答案,所以它可以帮助别人.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 = "somebodys@email.com",
      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,我希望这有帮助!!

401 不是“不能使用该方法”，而是“未经授权”。您遇到身份验证错误。从表面上看，您并没有以正确的方式进行基本身份验证。查看此示例以了解您缺少的详细信息。

PS：从 APIv3 返回的响应通常非常有帮助，因此您应该始终确保查看整个响应，而不仅仅是状态代码。
