Facebook Messenger:如何使用nodejs发送多条消息

这是我的代码(我在下面隐藏了PSID):

app.get('/helloguys', function (req, res) {

  var messageData = {
    batch: [
      {recipient: {id: "..."}},{recipient: {id: "..."}}
    ],
    message: {
      text: "Hi guys :)",
      metadata: "DEVELOPER_DEFINED_METADATA"
    }
  };

  request({
    uri: 'https://graph.facebook.com/v2.6/me/messages',
    qs: { access_token: token },
    method: 'POST',
    json: messageData

  }, function (error, response, body) {
       if (!error && response.statusCode == 200) {
         console.log("Ok", response.statusCode);
       } else {
         console.error("Failed calling Send API", response.statusCode, response.statusMessage, body.error);
       }
  });  

  res.send('Hi :)')

})

Ok 200

但是用户没有收到消息。

为什么?

编辑Lix:

body: 
2017-10-18T13:38:43.538998+00:00 app[web.1]:    [ { code: 400,
2017-10-18T13:38:43.538999+00:00 app[web.1]:        headers: [Object],
2017-10-18T13:38:43.538999+00:00 app[web.1]:        body: '{"error":{"message":"Unsupported get request. Please read the Graph API documentation at https:\\/\\/developers.facebook.com\\/docs\\/graph-api","type":"GraphMethodException","code":100,"error_subcode":33,"fbtrace_id":"Dd6+kHN7Tl+"}}' },

CBroe编辑:

  var messageData = {
    batch: [
      {method:"POST", message: "Hello", recipient: {id: "1552389158161227"}},{method:"POST", message: "Hello", recipient: {id: "1419003191530571"}}
    ]
  };

它不起作用

CBroe 2的编辑:

app.get('/helloguys', function (req, res) {

  var batch = [
      {method:"POST", body: "message=Test status update&amp;recipient=..."},
      {method:"POST", body: "message=Test status update&amp;recipient=..."}
    ];

  request({
    uri: 'https://graph.facebook.com/v2.6/me/messages',
    qs: { access_token: token },
    method: 'POST',
    json: batch

  }, function (error, response, body) {
       if (!error && response.statusCode == 200) {
         console.log("ok", response.statusCode, response.statusMessage, response);
         res.send('hi')
       } else {
         console.error("Failed calling Send API", response.statusCode, response.statusMessage, body.error);
       }
  });  

})

FB dev docs (他们在文件中的某个地方进行了说明,但不是很明显)

对于body参数

此外,多个岗位请求(批量请求):

虽然GET和DELETE操作只能有一个相对url和一个方法字段,但POST和PUT操作可能包含一个可选的url 领域

和gt&燃气轮机;

应将其格式化为 原始HTTP POST正文字符串

此外,此类请求应作为多部分/表单数据进行。

然后,批量请求要求是: (1) 是多部分/表格数据; (2) 由URL编码字符串组成 '正文' 参数 (3) 批处理请求应为原始HTTP POST正文字符串。

节点。js公司要求 表单数据 模块)。看见 docs

因此,您的代码应该是这样的>&燃气轮机;

app.get('/helloguys', function (req, res) {

  var batchUrl = 'https://graph.facebook.com';
  var r = request.post(batchUrl, function(error, response, body) {
    if (error) {return console.log("error\n", error)};
    console.log("successfull\n", body) //but fb sends error in body message, so check body.error for any errors
  });

  var form = r.form();
  var multipleMessages = [];
  var message = "message=" + encodeURIComponent(JSON.stringify(
          {
            "text": "âHi guys :)"
          }
  ));

  //loop throught user IDs (PSIDs)
  for (var i=0; i<users; i++) {
    var recipient = "recipient=" + encodeURIComponent(JSON.stringify({"id": users[i].id}));

    var batchMessage = {
      "method": "POST",
      "relative_url":"v2.6/me/messages",
      "body": recipient + "&" + message
    };
    multipleMessages.push(batchMessage);
  }

  form.append("access_token", token)
  form.append("batch", JSON.stringify(multipleMessages)); 

  res.send('Hi :)')

})
