通过Google App脚本将订户添加到Mailchimp列表

问题描述

我正在尝试使用连接到外部mailchimp API的google doc和google app脚本自动将订阅者添加到mailchimp邮件列表中。每当我尝试测试脚本时，都会从StackDriver Log中收到“错误值”异常。

var payload = {
    "email_address": email,"status_if_new": "subscribed","merge_fields": {
      FNAME: first_name,LNAME: last_name
    },};

  var headers = {
    "contentType": "application/json","Authorization": "apikey " + API_KEY,};

  var data = {
    "method": "PUT","muteHttpExceptions": false,"headers": headers,"payload": payload,};

  var json = Utilities.jsonStringify(data);
  
  //DEBUG
  Logger.log(json);
  Logger.log(endpoint);

  // call the Mailchimp API
  try {
    var response = UrlFetchApp.fetch(endpoint,json);

    if (response.getResponseCode() === 200) {
      // all good!
      Logger.log("Success");
      Logger.log(response);
    } else {
      Logger.log("Issues");
      Logger.log(response);
    }
  } catch (err) {
    // handle the error here
    Logger.log("Error");
    Logger.log(err);
  }

在进一步研究curl时，我发现手动发送具有相同有效负载和标头的请求会给出此响应。

curl -X PUT 'https://{server}.api.mailchimp.com/3.0/lists/{my_list}/members/{member_hash}' 
         -H {"Authorization":"apikey {API_KEY}","contentType":"application/json"} 
         -d '{"email_address":"[e-mail]","status_if_new":"subscribed","merge_fields":{"LNAME":"test","FNAME":"test"}},"muteHttpExceptions":false}' 

"errors":[{"field":"email_address","message":"This value should not be blank."}]

为什么API无法识别我提供的电子邮件？

解决方法

主要问题是您要传递一个JSON字符串作为params参数，其中UrlFetchApp.fetch(url,params)中应该有一个对象。无需对所有data进行字符串化，只需要对有效载荷进行字符串化即可。 （请注意Apps脚本文档中链接的示例。）

我怀疑您还会遇到Utilities.jsonStringify()的问题，因为它是deprecated。请改用JSON.stringify()。

我也将contentType从headers移到了data，因为这是在fetch()方法中指定的方式，但实际上对您的应用程序没有影响。

var payload = {
  "email_address": email,"status_if_new": "subscribed","merge_fields": {
    FNAME: first_name,LNAME: last_name
  },};

var headers = {
  "Authorization": "apiKey " + API_KEY
};

var data = {
  "method": "PUT","muteHttpExceptions": false,"headers": headers,"contentType": "application/json","payload": JSON.stringify(payload) // The payload should be stringified
};

//DEBUG
Logger.log(endpoint);

// call the Mailchimp API
try {
  var response = UrlFetchApp.fetch(endpoint,data); // pass in data,not json

  if (response.getResponseCode() === 200) {
    // all good!
    Logger.log("Success");
    Logger.log(response);
  } else {
    Logger.log("Issues");
    Logger.log(response);
  }
} catch (err) {
  // handle the error here
  Logger.log("Error");
  Logger.log(err);
}

如果您只是 要添加订户，那么我建议您使用add members to list端点。只是简单一点，不需要您生成成员哈希。
