Facebook graph api 如何解决；参数“U字段为必填项”；向应用程序订阅facebook页面时出错？

我正在创建一个应用程序，它将从我管理的facebook页面中提取线索，并随后将其更新到谷歌表单中

我已经设置了webhook，生成了具有以下权限的长寿命页面访问令牌

• 管理页面
• 页面显示列表
• 线索检索
• 广告管理
• 你读的广告

当我尝试使用POST请求

{page\u id}/subscribed\u apps

将页面订阅到我的应用时，我得到以下错误

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

调查显示，facebook在v3.2API中添加了一个名为subscribed_fields的新参数，但我不确定值必须如何传递给该参数，或者我缺少什么

当我尝试为facebook\u主打广告活动添加webhook时，我也遇到了同样的问题。。。它过去在以前的版本上工作得很好，我已经通过了以下范围： “管理页面”

函数myFacebookLogin（）{
FB.登录（功能（响应）{
console.log（'成功登录'，响应）；
FB.api（“/me/accounts”，
{限制：200}，
功能（响应）{
log（'成功检索页面'，响应）；
var pages=response.data；
var ul=document.getElementById（'list'）；
对于（变量i=0，len=pages.length；i

}

也许，这可以帮助你们：

以POST请求的形式如下：

因此，您需要创建此项。：）

我对权限有一些问题，奇怪的是，我在这里反复检查了我的页面权限： 似乎我有fb错误响应信息中遗漏的权限

我得到的回答是：

但我希望你能避免这个错误

从facebook api v3.2开始，我也遇到了问题

以下是@AdityaChowdhary的原始版本的修订内容：-添加“subscribed_fields:'leadgen'”作为post参数，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);
    });

FB.login(function (response) {
...
}, {scope: ['manage_pages', 'leads_retrieval']});

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\u retrieval”

为防止权限错误：将“leads\u retrieval”权限添加到fb.login范围，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);
    });

FB.login(function (response) {
...
}, {scope: ['manage_pages', 'leads_retrieval']});

在新的Graph API v3.2中，必须传递参数

subscribed_fields

，以及

post

请求

me/subscribed_apps

（页面访问令牌作为访问令牌）。您需要传递一组可用的可下标字段，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\u字段：[“消息”，“消息传递”]

在请求中添加subscribed\u字段=publisher\u订阅对我有效。
代码如下：

request({
        method: 'POST',
        uri: `https://graph.facebook.com/v2.6/me/subscribed_apps?subscribed_fields=publisher_subscriptions&access_token=${FB_PAGE_ACCESS_TOKEN}`
        },
        (error, response, body) => {
             if (error) {
                console.error('Error while subscription: ', error);
             } else {
                 console.log('Subscription result: ', response.body);
             }
       });

对于fb.login，您不能使用“管理页面”作为作用域，请尝试使用以下内容：

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

谢谢你的帮助！我能够成功地将页面切换到应用程序，但现在我在启动测试线索时收到错误102，并显示错误消息“服务器失败”。错误截图-Hi@solar_Consident
