我想从Facebook发布帖子和附件,所以我可以创建一个帖子列表。问题是,我想把属性:ID,消息和任何附件放在数组中,以便为每个帖子提供。我不确定是否需要在数组中迭代对象,或者我可以选择ID并获取相关信息。Node.js通过嵌套的Javascript对象循环
此外,我正在使用async.waterfall()来获取同步呼叫,因为我会进行其他调用,这取决于以前的调用。
我想这让附件的ID,消息和src网址:
var async = require("async");
var graph = require('fbgraph');
async.waterfall([
getFeed,
getPostPicture,
], function (err, result) {
});
function getFeed(callback) {
graph.get("/.../feed" + "?fields=message,attachments&access_token=APPID|APPSECRET", function(err, res) {
callback(null, res);
});
}
function getPostPicture(arg1, callback) {
var feedData = arg1.data;
for(var i in feedData)
{
var id = feedData[i].id;
var message = feedData[i].message;
var feedAttachment = feedData[i].attachments
for (var j in feedAttachment)
{
var attachment = feedAttachment.data;
var attachmentURL = attachment[i].src;
for (var j in attachmentURL)
{
var attachmentURL = feedAttachment.src;
}
}
}
console.log(attachment);
}
上面会输出:
[ { description: 'post message 1',
media: { image: [Object] },
target:
{ id: '...',
url: 'https://www.facebook.com/.../photos/a............/.../?type=3' },
title: 'Timeline Photos',
type: 'photo',
url: 'https://www.facebook.com/.../photos/a............/.../?type=3' } ]
下面是我第一次叫graph.get在响应源代码
,我需要{数据 - > [消息,ID,附件 - >数据[SRC]]}
{
"data": [
{
"message": "post message 1",
"id": "..._...",
"attachments": {
"data": [
{
"description": "picture 1",
"media": {
"image": {
"height": 256,
"src": "https://scontent.xx.fbcdn.net/v/t1.0-9/..._..._..._n.png?oh=...&oe=...",
"width": 256
}
},
"target": {
"id": "...",
"url": "https://www.facebook.com/.../photos/a............/.../?type=3"
},
"title": "Timeline Photos",
"type": "photo",
"url": "https://www.facebook.com/.../photos/a............./..../?type=3"
}
]
}
},
{
"message": "Test status update 123",
"id": "..._..."
}
],
"paging": {
"previous": "https://graph.facebook.com/v2.8/.../feed?fields=message,attachments&format=json&since=...&access_token=...&limit=25&__paging_token=enc_...&__previous=1",
"next": "https://graph.facebook.com/v2.8/.../feed?fields=message,attachments&format=json&access_token=...&limit=25&until=...&__paging_token=enc_..."
}
}
那么'console.log(附件);'net你输出的是什么?你确定你的代码粘贴正确吗?请展开您的代码以更好地显示在哪个点生成哪个输出。 – xDreamCoding
