javascript – 转换的JSON数组选择

所以我在Nodejs中创建了这段代码:

var stemidLength= JSON.memberList.members[0].length;

for (stemidIndex = 0; stemidIndex < stemidLength; stemidIndex++) {
  var steamID64Length= JSON.memberList.members[steamidIndex].steamID64.length;

  for (steamid64Index = 0; steamid64Index < steamid64Length; steamid64Index++) {
    steam.addFriend(steamID64[i]);
  }
}

我正在尝试从xml页面中提取steamid64s:http://steamcommunity.com/groups/Valve/memberslistxml/?xml=1.
我已经将xml页面转换为JSON数组.

我的代码有什么问题?得到错误:

cannot read property ‘members’ of undefined.

谢谢.

最佳答案 JSON对象是一个内置对象,用于解析JSON并将字符串转换为JSON.它没有memberList属性.

我将把XML到JSON转换的结果称为steamUsers.

可以在steamUsers.memberList.members [0] .steamID64中找到ID.您可以使用以下代码添加ID:

xmlToJson(urlxml, function(err, data) {
    if (err) {
        return console.err(err);
    }

    var steamUsers = data;
    steamUsers.memberList.members[0].steamID64.forEach(function(memberID) {
        steam.addFriend(memberID);
        console.log(memberID);
    });
});
