向 MailChimp 添加新订阅者返回错误请求

Question

为了使用 API 3.0 将订阅者添加到 MailChimp 列表，需要参数 e-mailadress 和 status。如果请求成功，响应将包含 json 格式的 id。

我的问题是，当我使用成员类添加订阅者时，请求发送的 id 为空，因此我收到错误错误请求。如何将我的成员类更改为仅从响应中读取 id 而不在请求中添加它？我正在使用 RestSharp、Visual Studio 2013、.Net 4.0，

我的成员类是这样的

public class Member
{            
    public Member(){}
    public Member(string status)
    {
        this.status = status;
    }
    public Member(string email_address, string status)
    {
        this.status = status;
        this.email_address = email_address;
    }
    public string id { get; set; } 
    public string email_address { get; set; }
    public string status { get; set; }
}

我的 createMember 函数如下所示：

static void createMember()
{
    var client = new RestClient();
    client.BaseUrl = new Uri("https://" + dc + ".api.mailchimp.com/3.0");

    //HTML Basic Authentification
    client.Authenticator = new HttpBasicAuthenticator(usernsme, apiKey);

    var request = new RestRequest(Method.POST);
    request.Resource = "lists/{list_id}/members";

    request.AddUrlSegment("list_id", listId);

    request.RequestFormat = DataFormat.Json;

    request.AddBody(new Member(memberEmail, "subscribed"));

    RestClient.AddHandler();
    IRestResponse<Member> response2 = client.Execute<Member>(request);
    string _id = response2.Data.id;

    Console.WriteLine(response.StatusCode);
    Console.WriteLine(_id);
}

如果我从成员类中删除 id，我可以将订阅者添加到列表中，但是如何从响应中获取 Id 并使用它？

Answer 1

根据their reference，你调用的API方法有不同的请求体参数和响应体参数，所以我建议使用两个不同的类。第一个是MemberRequest，用于请求，没有id 字段

public class MemberRequest
{
    public MemberRequest(){}

    public MemberRequest(string status)
    {
        this.status = status;
    }

    public MemberRequest(string email_address, string status)
    {
        this.status = status;
        this.email_address = email_address;
    }

    public string email_address { get; set; }
    public string status { get; set; }
}

第二个是MemberResponse，用于响应并具有id 字段

public class MemberResponse
{
    public string id { get; set; }
    public string email_address { get; set; }
    public string status { get; set; }
}

这是您的 createMember 方法的样子

static void createMember()
{
    var client = new RestClient();
    client.BaseUrl = new Uri("https://" + dc + ".api.mailchimp.com/3.0");

    //HTML Basic Authentification
    client.Authenticator = new HttpBasicAuthenticator(usernsme, apiKey);

    var request = new RestRequest(Method.POST);
    request.Resource = "lists/{list_id}/members";

    request.AddUrlSegment("list_id", listId);

    request.RequestFormat = DataFormat.Json;

    request.AddBody(new MemberRequest(memberEmail, "subscribed"));

    IRestResponse<MemberResponse> response = client.Execute<MemberResponse>(request);
    string _id = response.Data.id;

    Console.WriteLine(response.StatusCode);
    Console.WriteLine(_id);
}
