获取所有列表成员 - MailChimp 3.0

【中文标题】获取所有列表成员 - MailChimp 3.0

【英文标题】：Get All List Members - MailChimp 3.0

【问题描述】：

我正在尝试获取列表中的所有成员（大约 19,000 名成员），并在 C# 中使用 Mailchimp.NET.V3 包。

以下代码只检索前 1000 个成员

IMailChimpManager MC = new MailChimpManager(@"xxxxxxxxxxxxxxxxxxxxxxxxx-xxx");
var listMembers = await MC.Members.GetAllAsync(ListId);

我也尝试过使用MemberRequest 构造函数，但这永远不会返回任何值。

var listMembers = await MC.Members.GetAllAsync(ListId, new MemberRequest  Limit = 20000  );

有人可以帮忙吗？谢谢！

【参考方案1】：

您需要使用 'count' 参数，而不是限制。

【参考方案2】：

使用偏移值。

List<Member> listMembers = new List<Member>();
IMailChimpManager manager = new MailChimpManager(MailChimpApiKey);
bool moreAvailable = true;
int offset = 0;
while (moreAvailable)

    var listMembers = manager.Members.GetAllAsync(yourListId, new MemberRequest
    
        Status = Status.Subscribed,
        Limit = 250,
        Offset = offset
    ).ConfigureAwait(false);

    var Allmembers = listMembers.GetAwaiter().GetResult();
    foreach(Member member in Allmembers)
    
        listMembers.Add(member);
    
    if (Allmembers.Count() == 250)
        //if the count is < of 250 then it means that there aren't more results
        offset += 250;
    else
        moreAvailable = false;

【参考方案3】：

我在 unity 3D 上使用 C# 脚本完成了类似的操作，包括基本身份验证和 WWW 请求。此脚本使用 API 3.0 返回 Mailchimp 上列表的成员。也许这段代码有帮助。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class mailchimpRESTful : MonoBehaviour 

    /*
     *  USE using CURL:
     * 
        curl --request GET \
            --url 'https://<dataCenter>.api.mailchimp.com/3.0/lists/<your-list-name>/members/' \
            --user 'anystring:<mailchimp-api-key>'

        EXAMPLE using CURL:

        curl --request GET \
            --url 'https://us12.api.mailchimp.com/3.0/lists/era987af43/members/' \
            --user 'anystring:e419ac3fefefgkjne0559901222a3dbf-us12'
    */

    // Mailchimp API RESTful C# script GET Member list 

    private const string DC       = "<your-data-center>";       // us1,us2..us18 
    private const string LIST     = "<your-list-name>";        // Something similar to: era987af43
    private const string URL      = "<your-url>";              // "https://<dataCenter>.api.mailchimp.com/3.0/lists/<your-list-name>/members/";
    private const string USER     = "anystring";               // You can use any user
    private const string API_KEY  = "your-api-key";            // Mailchimp API-key: e419ac3fefefgkjne0559901222a3dbf-us12

    public void Start()
    
        Request ();
    


    public void Request()
    
        Dictionary<string, string> headers = new Dictionary<string,string>();
        headers ["Authorization"] = "Basic " + System.Convert.ToBase64String (System.Text.Encoding.ASCII.GetBytes (USER + ":" + API_KEY));

        WWW request = new WWW(URL, null, headers);
        StartCoroutine (OnResponse (request));
    

    private IEnumerator OnResponse(WWW req)
    
        yield return req;
        Debug.Log ("Query Result:"+req.text);
    

【参考方案4】：

    private async Task<List<Member>> GetMemberListAsync(string listId)
    
        var offset = 0;
        var moreAvailable = true;
        var listMembers = new List<Member>();

        while (moreAvailable)
        
            var result = await manager.Members.GetAllAsync(listId, new MemberRequest
            
                Status = Status.Subscribed,
                Limit = 250,
                Offset = offset
            );

            var resultList = result.ToList();

            foreach (var member in resultList)
            
                listMembers.Add(member);
            

            if (resultList.Count() == 250)
                offset += 250;
            else
                moreAvailable = false;
        

        return listMembers;
    

【参考方案5】：

var listMembers = manager.Members.GetAllAsync(ListId).ConfigureAwait(false);

var Allmembers = listMembers.GetAwaiter().GetResult();

【讨论】：

虽然这段代码 sn-p 可以解决问题，但including an explanation 确实有助于提高帖子的质量。请记住，您正在为将来的读者回答问题，而这些人可能不知道您的代码建议的原因。也请尽量不要用解释性的 cmets 挤满你的代码，因为这会降低代码和解释的可读性！

代码sn-p只返回1000，作者想得到19000。
