我的 facebook 应用程序无法接收网页 webhook

如何解决我的 facebook 应用程序无法接收网页 webhook

我尝试制作一个机器人来响应客户的消息和评论。

Webhook 仅在用户与页面聊天时发送，但当用户回复或发布时，我无法收到任何 Webhook。 我有“pages_manage_Metadata”权限，并设置了我的代码以接收页面 webhook，如下所示：

app.post("/webhook",(req,res) => {
let body = req.body;
//const page_id=process.env.page_id;

// Checks if this is an event from a page subscription
if (body.object === "page") {
// Iterates over each entry - there may be multiple if batched
body.entry.forEach(function(entry) {
  if (entry.messaging) {
    // Gets the body of the webhook event
    let webhookEvent = entry.messaging[0];
    console.log(webhookEvent);

    // Get the sender PSID
    let senderPsid = webhookEvent.sender.id;
    console.log("Sender PSID: " + senderPsid);

    // Check if the event is a message or postback and
    // pass the event to the appropriate handler function
    if (webhookEvent.message) {
      handleMessage(senderPsid,webhookEvent.message);
    } else if (webhookEvent.postback) {
      handlePostback(senderPsid,webhookEvent.postback);
    }
  } else if (entry.changes) {
    let webhookEvent = entry.changes[0];
    console.log("webhookEvent=",webhookEvent);
    if (webhookEvent.field === "Feed") {
      console.log("Feed");

      let comment_id;
      let comment = webhookEvent.value;
      let comment_type = comment.item;

      if (comment_type == "post") {
        comment_id = comment.post_id;
        console.log("detect post");
      } else if (comment_type == "comment") {
        comment_id = comment.comment_id;
        console.log("detect comment");
      } else if (comment_type == "status") {
        comment_id = comment.post_id;
        console.log("detect status");
      }

      console.log("comment_id: " + comment_id);

      let message = comment.message;
      console.log("message: " + message);

      let user_id = comment.from.id;
      console.log("user_id: " + user_id);
      console.log(
        "+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++"
      );
      send_private_reply(comment_id);
      processComments(comment_id,comment_type,user_id,message);
    }
  }
});

// Returns a '200 OK' response to all requests
res.status(200).send("EVENT_RECEIVED");
} else if (body.object === "user") {
body.entry.forEach(function(entry) {
  console.log(
    "user event---------------------------------------------------"
  );
  console.log("Facebook request body:",body);
  console.log("entry.changes=",entry.changes);
  res.status(200).send("EVENT_RECEIVED");
});
} else {
 // Returns a '404 Not Found' if event is not from a page subscription
 console.log("enent not found$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$");
 res.sendStatus(404);
 }
});
