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 ;

• Scott #1

  item.lenght;
  
  是不是拼错了： item.length

• ReadingCommando 回复 Scott #2

  回复 Scott是啊，谢谢啊！！！
