文件data.txt的内容

{"title":"Hello","content":"nihao","id":1439883748614}
{"title":"Hello","content":"nihao","id":1439883789405}
{"title":"Hello","content":"nihao","id":1439883893949}
{"title":"Hello","content":"nihao","id":1439883895058}
{"title":"Hello","content":"nihao","id":1439883896144}

js代码:

 var fs=require('fs');
    fs.readFile('./data/data.txt','utf-8',function(err,data){  
        if(err){
            console.log("error");  
        }else{
            var array=data.split('\n');
            for (var i = 0; i < array.length; i++) {
                var str=array[i];
                console.log(str);
                var b=JSON.parse(str);
            }
        }  
    });

明明是标准的json，为什么老是报错？错误：

SyntaxError: Unexpected end of input
