我有以下要解析为 JSON 的字符串:

{
    "STATUS": [
        {
            "STATUS": "S",
            "When": 1394044643,
            "Code": 17,
            "Msg": "GPU0",
            "Description": "cgminer 3.7.3"
        }
    ],
    "GPU": [
        {
            "GPU": 0,
            "Enabled": "Y",
            "Status": "Alive",
            "Temperature": 70,
            "Fan Speed": 3089,
            "Fan Percent": 70,
            "GPU Clock": 1180,
            "Memory Clock": 1500,
            "GPU Voltage": 1.206,
            "GPU Activity": 99,
            "Powertune": 20,
            "MHS av": 0.4999,
            "MHS 5s": 0.5009,
            "Accepted": 4335,
            "Rejected": 7,
            "Hardware Errors": 0,
            "Utility": 27.8007,
            "Intensity": "0",
            "Last Share Pool": 0,
            "Last Share Time": 1394044643,
            "Total MH": 4676.7258,
            "Diff1 Work": 69436,
            "Difficulty Accepted": 69360,
            "Difficulty Rejected": 112,
            "Last Share Difficulty": 16,
            "Last Valid Work": 1394044643,
            "Device Hardware%": 0,
            "Device Rejected%": 0.1613,
            "Device Elapsed": 9356
        }
    ],
    "id": 1
}

当我使用例如http://jsonlint.com/ 它说 JSON 是正确的但是当我在 node.js 中使用时:

console.log(JSON.parse(data.toString()));

我得到以下信息:

undefined:1
e Hardware%":0.0000,"Device Rejected%":0.1570,"Device Elapsed":9554}],"id":1}
                                                                             ^
SyntaxError: Unexpected token

知道我在这里做错了什么吗？

数据以字节流的形式出现:

.on('data',function(data){
  console.log(data.toString());
  console.log();
  console.log(data);
  console.log();
  console.log("data "+ data.GPU);
  //...

当我这样做时:

console.log(data.toString());
console.log(JSON.stringify(data.toString()));

我得到以下结果:

"{"STATUS":[{"STATUS":"S","When":1394046864,"Code":17,"Msg":"GPU0","Description":"cgminer 3.7.3"}],"GPU":[{"GPU":0,"Enabled":"Y","Status":"Alive","Temperature":70.00,"Fan Speed":3087,"Fan Percent":70,"GPU Clock":1180,"Memory Clock":1500,"GPU Voltage":1.206,"GPU Activity":99,"Powertune":20,"MHS av":0.5000,"MHS 5s":0.5016,"Accepted":5396,"Rejected":8,"Hardware Errors":0,"Utility":27.9597,"Intensity":"0","Last Share Pool":0,"Last Share Time":1394046864,"Total MH":5789.2352,"Diff1 Work":86428,"Difficulty Accepted":86336.00000000,"Difficulty Rejected":128.00000000,"Last Share Difficulty":16.00000000,"Last Valid Work

注意第二条消息的最后一个 unicode 字符 \u0000 我能用它做什么？

最佳答案

问题出在终止空字符上。删除它后，我现在可以毫无问题地解析字符串(如果有的话，发布更有效的方法)

var re = /\0/g;
str = data.toString().replace(re, "");
var o = JSON.parse(str);
console.log(o);

或

var str = data.toString().slice(0, - 1);

或者直接在 Buffer 中处理字节

var buf = data.slice(0,data.length-1);
console.log(JSON.parse(buf.toString()));

关于javascript - 使用 Node 将字符串解析为 JSON 会给出意外的标记，验证器说可以，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22206426/
