javascript - mailchimp取消订阅 Node js服务器

我对mailchimp取消订阅过程有疑问。
请您为我提供退订流程的方法。如何准确地放入退订列表以及我应该请求哪些文件。以及我如何知道应将电子邮件放入退订列表的区别。

mailchimp.post('/lists/{id}', {
      email_address : "[email protected]"
    })
      .then(function(results) {
        console.log(results)
      })
      .catch(function (err) {
        console.log(err)
      });

响应错误

最佳答案

mailchimp.post('/lists/{id}', {
    "members" : [{"email_address": email, "status": "unsubscribed"}],"update_existing":true
})
.then(function(results) {
    console.log(results)
})
.catch(function (err) {
    console.log(err)
});
