有人可以提供在 ASP.NET 中执行此操作的示例。我们想做一些 MailCHimp – 内部数据库同步,并计划使用 webhook 功能做到这一点,但我们无法让它工作。当有人取消订阅邮件黑猩猩时,我们希望使用网络挂钩来同步数据。
要解决的另一件事是安全性。我们如何保护该页面不被恶意用户访问?
这是一段对我们有用的代码。这相当简单,但确实需要我们进行一些实验才能使其正常工作。
if (Request.Form["type"] != null && Request.Form["type"] == "unsubscribe")
{
string email = Request.Form["data[merges][EMAIL]"];
//now you can do insert/update data in your local database
}
查看 API 文档以获取更多详细信息http://apidocs.mailchimp.com/webhooks/
关于安全性,您可以做很多事情,但这取决于您想走多远。我建议的一件事是检查您的 IIS 日志并查找邮件黑猩猩使用哪个 IP 地址/用户代理来触发 Web 挂钩,然后只为除此之外的所有其他 IP 地址阻止此页面。您可能还可以采取其他措施来保护这一点,例如使用不容易猜到的页面名称(f3jijselife.aspx 比 webhooks.aspx 好得多)
我最近刚刚根据他们提供的 PHP 代码实现了这个框架......我拿出了实际的实现,但希望应该有用

我正在使用 C# WebAPI,我的解决方案是使用来自 POST MailChimp 正文的 FormDataCollection 对象与 webhook 一起发送。
using System.Net.Http.Formatting;
[HttpPost]
[Route("mailchimp/subscriber")]
public IHttpActionResult Post([FromBody] FormDataCollection data)
{
if (data != null)
{
string type = data.Get("type");
if (!string.IsNullOrWhiteSpace(type))
{
string listId = data.Get("data[list_id]");
string id = data.Get("data[id]");
string firstName = data.Get("data[merges][FNAME]");
string lastName = data.Get("data[merges][LNAME]");
string email = data.Get("data[email]");
if (!string.IsNullOrWhiteSpace(email))
{
// Do something with the subscriber
}
}
}
}
我完全支持詹姆斯的回答。
但是,在尝试自己实现 webhook 时,我发现您还需要实现 GET 方法,以便甚至能够在 MailChimp 中创建 webhook。
这对我有用:
[HttpGet]
[HttpOptions]
public HttpResponseMessage Get()
{
return Request.CreateResponse(HttpStatusCode.OK);
}
