Question

我正在尝试使用facebook node sdk module将照片发送到页面。 https://github.com/Thuzi/facebook-node-sdk/

我可以发布到页面墙或从网址上传。但我试图从数据上传照片时遇到问题。

这就是我的联系方式：

FB.api('oauth/access_token', {
        client_id: clientid,
        client_secret: clientsecret,
        redirect_uri: redirecturi,
        code: code,
        scope: scope,
        fileUpload : true,
    }, function (resf) { ...}

我得到了这样的好的访问令牌：

 FB.api('/me/accounts', function (resf) {
            if (!resf || resf.error) {
                console.log(!resf ? 'error occurred' : resf.error);
                return;
            }

            for (var i = 0; i < resf.data.length; i++) {
                if (resf.data[i].id == pageid)
                {
            resf.data[i]. access_token
                    }
    });

我尝试上传照片：

                    FB.api(pageid + '/photos', 'post', { message: body, source: buff, }, function (resf) {
                        if (!resf || resf.error) {
                            console.log(!resf ? 'error occurred' : resf.error);
                            return;
                        }
                        console.log( resf);
                        res.send(resf);
                    });

我有这个错误：

{
  "error": {
    "message": "(#324) Requires upload file",
    "type": "OAuthException",
    "code": 324
  }
}

此通话有效：

var body = 'My firstdfsfsfd';
                        FB.api(pageid + '/photos', 'post', { message: body, url: 'url_image', }, function (resf) {
                            if (!resf || resf.error) {
                                console.log(!resf ? 'error occurred' : resf.error);
                                return;
                            }
                            console.log( resf);
                            res.send(resf);
                        });

我忘记了什么？

此模块允许使用分段上传：https://github.com/Thuzi/facebook-node-sdk/

Answer 1

它似乎不支持multipart。您可以使用request模块手动执行此操作：

var request = require('request');

// ....

var access_token = 'abc123',
    pageid = 'me',
    fburl = 'https://graph.facebook.com/'
            + pageid
            + '/photos?access_token='
            + access_token,
    req,
    form;

req = request.post(fburl, function(err, res, body) {
  if (err)
    return console.error('Upload failed:', err);
  console.log('Upload successful! Server responded with:', body);
});
form = req.form()
// append a normal literal text field ...
form.append('message', 'My photo!');

// append a file field by streaming a file from disk ...
form.append('source', fs.createReadStream(path.join(__dirname, 'photo.jpg')));
// or append a Buffer ...
form.append('source', someBuffer);
// or append the contents of a remote url ...
form.append('source', request('http://google.com/doodle.png'));

Answer 2

上面的示例（来自mscdex）适用于：

form.append('source', requestLib('<imageURL>'));

给予回应：

{ “ID”： “756317401077924”， “POST_ID”： “100000990137087_756310827745248”}

也适用于：

form.append('source', fs.createReadStream('<imagepath>'));

给予回应：

{ “ID”： “756328687743462”， “POST_ID”： “100000990137087_756310827745248”}

这可能就是我所需要的。谢谢mscdex，非常有帮助。但出于好奇，当我用图像缓冲区替换它时：

form.append('source', imageBuffer);

它提供与OP相同的错误（即使使用与OP相同的图像字符串）：

{“error”：{“message”：“（＃324）需要上传文件”，“类型”：“OAuthException”，“code”：324}}

为什么呢？我的猜测是Facebook想要一个特定的编码图像格式。

使用facebook-node-sdk进行照片上传模块/（＃324）需要上传文件
