paypal ipn交易数组中缺少字母

有人能告诉我这是IPN的正确回答吗？我没有发现任何文件表明缺少字母的索引事务。有没有人遇到过这个问题

传输格式不正确：

谢谢，

我已经检查了原始数据，它是正确的。问题是sails express bodyParser以错误的方式解析。我已将bodyParser更改为：

module.exports = {
    express: {
        'bodyParser' : function(options){
            var _urlencoded = urlencoded(options)
            , _multipart = multipart(options)
            , _json = json(options);

            return function bodyParser(req, res, next) {

                var buf = '';
                req.setEncoding('utf8');
                req.on('data', function(chunk){ buf += chunk });
                req.on('end', function(){
                    req.rawBody = buf;
                });             

                _json(req, res, function(err){
                    if (err) return next(err);
                        _urlencoded(req, res, function(err){
                            if (err) return next(err);
                                _multipart(req, res, next);
                        });
                });
            }
        }
    }

以及使用新的req.rawBody属性的ipn验证函数

谢谢大家
