使用节点将stringparsing为JSON会产生意外的令牌，validation器说ok
我有以下string，我想parsing为JSON：
{ "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：
console.log(JSON.parse(data.toString()));
我得到以下内容：
undefined:1 e Hardware%":0.0000,"Device Rejected%":0.1570,"Device Elapsed":9554}],"id":1} ^ SyntaxError: Unexpected token
任何线索我在这里做错了什么？

数据以ByteStream的forms出现：

当我这样做：
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 ":1394046864,"Device Hardware%":0.0000,"Device Rejected%":0.1481,"Device Elapsed":11580}],"id":1}" "{\"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 Sp eed\":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,\"Hardw are 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 Re jected\":128.00000000,\"Last Share Difficulty\":16.00000000,\"Last Valid Work\":1394046864,\"Device Hardware%\":0.0000,\"Device Rejected%\":0.1481,\"Device Elapsed\":11580}],\"id\":1}\u0000"
注意第二个消息的最后一个Unicode字符\u0000我可以用它做什么？
问题是终止空字符。 删除后，我现在可以parsingstring没有问题（如果你有它后更有效的方式）
var re = /\0/g; str = data.toString().replace(re, ""); var o = JSON.parse(str); console.log(o);
要么
var str = data.toString().slice(0, - 1);
或直接在Buffer字节上工作
var buf = data.slice(0,data.length-1); console.log(JSON.parse(buf.toString()));
我复制了你的控制台日志输出data.toString（）和和@patryk指出，在string的末尾有一个Unicode字符\ u0000。 这可能会导致问题。 我删除了尾随字符，将string赋值给一个variables，并创build了一个缓冲区，一切都是hunky dory。
var a = '{"STATUS":[{"STATUS":"S","When":1394045650,"Code":17,"Msg":"GPU0","Description":"cgminer 3.7.3"}],"GPU":[{"GPU":0,"Enabled":"Y","Status":"Alive","Temperature":70.00,"Fan Speed":3090,"Fan Percent":70,"GPU Clock":1180,"Memory Clock":1500,"GPU Voltage":1.206,"GPU Activity":99,"Powertune":20,"MHS av":0.4999,"MHS 5s":0.5007,"Accepted":4841,"Rejected":8,"Hardware Errors":0,"Utility":28.0261,"Intensity":"0","Last Share Pool":0,"Last Share Time":1394045638,"Total MH":5181.3734,"Diff1 Work":77548,"Difficulty Accepted":77456.00000000,"Difficulty Rejected":128.00000000,"Last Share Difficulty":16.00000000,"Last Valid Work":1394045638,"Device Hardware%":0.0000,"Device Rejected%":0.1651,"Device Elapsed":10364}],"id":1}'; var b = new Buffer(a); console.log(JSON.parse(b.toString());
