发送的消息收到了，但在执行var message = util.formatMessage(content.xml);方法时报错。卡了快一周了，求拯救啊！

应该是 xml 的模板代码写错了，检查下标签大小写啊，语法嵌套啊，是否关闭啊，多余空格啊之类的

这个不是xml模版的问题，我遇到问题和你一样。要感谢 nodejs微信课程群2 @Along的帮助问题顺利的解决了。
function formatMessage(result) {
var message = {};
if (typeof result === 'object') {
var keys = Object.keys(result);
for (var i = 0; i < keys.length; i++) {
var item = result[keys[i]];
var key = keys[i];
if (!(item instanceof Array) || item.length === 0) {
continue;
}
if (item.length === 1) {
var val = item[0];
if (typeof val === 'object') {
mesage[key] = formatMessage(val);
} else {
message[key] = (val || '').trim();
}
} else {
message[key] = [];
for (var j = 0, k = item.lenght; j < k; j++) {
message[key].push(formatMessage(item[j]));
}
}
}
}
return message;
}
exports.formatMessage = formatMessage ;
