我只想向所有具有nodejs的订阅者发送消息。 这是我的代码(我隐藏了下面的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 :)')
})
我在nodejs控制台中得到了这个:
Ok 200
但是用户没有收到该消息。
为什么?
为Lix编辑:
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+"}}' },
为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
编辑CBroe 2:
app.get('/helloguys', function (req, res) {
var batch = [
{method:"POST", body: "message=Test status update&recipient=..."},
{method:"POST", body: "message=Test status update&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);
}
});
})
现在我明白了:
2017-10-18T15:36:05.981999+00:00 app[web.1]: Failed calling Send API 400 Bad Request { message: '(#100) The parameter recipient is required',
2017-10-18T15:36:05.982009+00:00 app[web.1]: type: 'OAuthException',
2017-10-18T15:36:05.982010+00:00 app[web.1]: code: 100,
2017-10-18T15:36:05.982011+00:00 app[web.1]: fbtrace_id: 'EJLQgP9UoMT' }

根据FB dev docs(他们在文档中的某处说明,并不是很明显)
请注意body param的 URLEncoding
此外,多个 POST 请求(批量请求):
虽然GET和DELETE操作只能有一个relative_url和一个方法字段,但POST和PUT操作可能包含一个可选的 body 字段。
和>>
这应格式化为原始HTTP POST正文字符串,类似于URL查询字符串。
此外,此类请求应作为multipart / form-data。
然后,批量请求要求是: (1)是多部分/表格数据; (2)由' body' 参数中的URLEncoding字符串组成; (3)批处理请求应该是原始的HTTP POST正文字符串。
Node.js request 模块可以发送表单数据(通过表单数据模块)。见docs
所以,你的代码应该是这样的>>
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": "Hi 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 :)')
})
答案 1 :(得分:-1)
尝试在请求回调中移动res.send('Hi'):
function (error, response, body) {
if (!error && response.statusCode == 200) {
console.log("Ok", response.statusCode);
res.send('Hi');
} else {
console.error("Failed calling Send API", response.statusCode, response.statusMessage, body.error);
}
});
