Question

我正在创建一个应用程序，该应用程序将从我管理的Facebook页面上获取线索，然后将其更新到Google表格中。

我已经设置了Webhook，并生成具有以下权限的长寿命页面访问令牌

manage_pages
pages_show_list
leads_retrieval
ads_management
ads_read

当我尝试使用POST请求{page_id}/subscribed_apps将页面订阅到我的应用程序时，出现以下错误

{
  "error": {
    "message": "(#100) The parameter subscribed_fields is required.",
    "type": "OAuthException",
    "code": 100,
    "fbtrace_id": "Fv7RbO8tYqo"
  }
}

研究表明，facebook在v3.2 api中添加了一个名为subscribed_fields的新参数，但是我不确定如何将值传递给该参数，或者我缺少什么？

Answer 1

在新的Graph API v3.2中，您必须传递参数subscribed_fields和post请求me/subscribed_apps（以页面访问令牌作为访问令牌）。您需要传递一个可用的可订阅字段数组，这些字段是：

[
    feed, mention, name, picture, category, description, conversations,
    branded_camera, feature_access_list, standby,
    messages, messaging_account_linking, messaging_checkout_updates,
    message_echoes, message_deliveries, messaging_game_plays, messaging_optins,
    messaging_optouts, messaging_payments, messaging_postbacks,
    messaging_pre_checkouts, message_reads, messaging_referrals,
    messaging_handovers, messaging_policy_enforcement,
    messaging_page_feedback, messaging_appointments, founded,
    company_overview, mission, products, general_info, leadgen,
    leadgen_fat, location, hours, parking, public_transit,
    page_about_story, phone, email, website, ratings, attire,
    payment_options, culinary_team, general_manager, price_range,
    awards, hometown, current_location, bio, affiliation, birthday,
    personal_info, personal_interests, publisher_subscriptions, members,
    checkins, page_upcoming_change, page_change_proposal,
    merchant_review, product_review, videos, live_videos, registration,
]

例如：subscribed_fields: ['messages', 'message_deliveries']

Answer 2

当我尝试为facebook_lead ads广告活动添加webhook时，我遇到了同样的问题...它曾经在以前的版本中完美运行，并且通过了范围： “ manage_pages”

function myFacebookLogin() {
FB.login(function(response){
  console.log('Successfully logged in', response);
  FB.api('/me/accounts', 
    {limit: 200}, 
    function(response) {
    console.log('Successfully retrieved pages', response);
    var pages = response.data;
    var ul = document.getElementById('list');
    for (var i = 0, len = pages.length; i < len; i++) {
      var page = pages[i];
      var li = document.createElement('li');
      var a = document.createElement('a');
      a.href = "#";
      a.onclick = subscribeApp.bind(this, page.id, page.access_token);
      a.innerHTML = page.name;
      li.appendChild(a);
      ul.appendChild(li);
    }
  });
}, {scope: 'manage_pages'});

}

Answer 3

也许，这对你们有帮助：

https://developers.facebook.com/docs/graph-api/reference/page/subscribed_apps/#Creating

像这样的POST请求形式： https://graph.facebook.com/v3.2/me/subscribed_apps?subscribed_fields=

因此您需要创建它。：）

我的权限有问题，这很奇怪，因为我在这里仔细检查了我的页面权限： https://developers.facebook.com/tools/debug/accesstoken 似乎我有fb错误响应消息中缺少的权限。

我得到了这个答复：

但我希望您可以避免此错误。：）

Answer 4

从facebook api v3.2开始，我还遇到了问题。

这是解决@AdityaChowdhary最初问题的方法：-添加“ subscribed_fields：'leadgen'”作为后置参数，如下所示：

def addlst(list_, item):
    """add an item to a list"""
    if isinstance(item, str):
        item = item.capitalize()
    list_.append(item)
    return list_

然后，您可能会遇到另一个错误：“要订阅Leadgen字段，需要以下权限之一：Leads_retrieval”。

为防止出现权限错误：将fb.login范围添加“ leads_retrieval”权限，如下所示：

FB.api(
    '/' + page_id + '/subscribed_apps',
    'post',
      { access_token: page_access_token, subscribed_fields: 'leadgen' },
    function (response) {
        console.log('Successfully subscribed page', response);
    });

Answer 5

在请求中添加 subscribed_fields = publisher_subscriptions 对我有用。
这是代码：

DATETIME

Answer 6

对于fb.login，您不能使用'manage_pages'作为范围，请尝试使用以下内容：

{scope: ['pages_show_list','leads_retrieval']}

向应用程序订阅Facebook页面时，如何解决“参数subscribed_fields是必需的”错误？
