Javascript Node.js：在客户端处理JSON对象

我在使用socket.io处理Node.js服务器客户端的JSON对象时遇到问题

这是我发送数据的方式，我正在读取的文件具有JSON格式：

io.on('connection', function(socket){
    console.log("A user connected");
    fs.readFile('/.../file.json', 'utf-8', function(err, data){
        socket.emit('news', JSON.stringify(data));
    });
    socket.on('disconnect', function(){
        console.log("A user disconnected");
    });
});

我调用JSON.stringify以便为二进制数据提供可读的格式

现在，在客户端，html的内部有以下块：

---

根据JSON Lint的说法，这是一个有效的JSON，但是当我试图访问时间戳标记时，我仍然没有定义，客户机和服务器之间应该没有关系。事实上，您使用的node.js恰好是JavaScript，这与客户端无关

如果您在C或Java中执行了相同的操作，这对客户机是否重要

---

总之，第1步应该是验证您的JSON对象是否在客户端上正确接收。然后，使用诸如的验证器确保JSON是有效的对象。如果无效，则问题出在服务器端。如果没有，您需要检查客户端的解析。

我发送了错误的数据格式，正确的代码是：

io.on('connection', function(socket){
    console.log("A user connected");
    fs.readFile('/.../file.json', 'utf-8', function(err, data){
        socket.emit('news', data.toString());
    });
    socket.on('disconnect', function(){
        console.log("A user disconnected");
    });
});

---

我在两侧调用JSON.parse来检查我处理的数据是否正确，并且没有收到任何错误。我还复制粘贴了console.logobj在JSON Lint中的输出，它说这是一个有效的jsonMaybe，如果它有效，您应该接受自己的答案；我试过了，但它说我需要在2天内回来接受它。那我就做；
