有效的 json 字符串但无法解析答案

【问题标题】：valid json string but cannot parse有效的 json 字符串但无法解析
【发布时间】：2019-12-11 17:25:46
【问题描述】：

我的环境是nodejs

let z = await x.text();
console.log(z)
let y = JSON.parse(z)

控制台日志是

{
   "errorCode":0,
   "errorMsg":"success",
   "result":{
      "msg":"\u4e70\u5bb6\u5df2",
      "uid":"104",
      "username":"\u738b\u626d",
      "userphone":"1565777778",
      "address":"\u4e0a\u6d77",
      "price":"5.00",
      "trade_state":"TRADE_SUCCESS",
      "hk_orderid":"1575524694820"
   }
}

(node:21) UnhandledPromiseRejectionWarning: SyntaxError: Unexpected 位置 0 处的 JSON 中的标记

当我复制 json 字符串并将其粘贴到

JSON.parse('{"errorCode":0,"errorMsg":"success","result":{"msg":"\u4e70\u5bb6\u5df2","uid":"104","username":"\u738b\u626d","userphone":"1565777778","address":"\u4e0a\u6d77","price":"5.00","trade_state":"TRADE_SUCCESS","hk_orderid":"1575524694820"}}')

在浏览器控制台内

解析正确

编辑：有人问json，实际上json正是我上面粘贴的

{
   "errorCode":0,
   "errorMsg":"success",
   "result":{
      "msg":"\u4e70\u5bb6\u5df2",
      "uid":"104",
      "username":"\u738b\u626d",
      "userphone":"1565777778",
      "address":"\u4e0a\u6d77",
      "price":"5.00",
      "trade_state":"TRADE_SUCCESS",
      "hk_orderid":"1575524694820"
   }
}

这也是console.log(z)的输出

下面是一些进一步的日志，注意只有最后一个有异常

【问题讨论】：

你能粘贴console.log(z)的结果吗
stackoverflow.com/a/20392392/8813684 检查它是否是 json，然后如果抛出任何异常，则从这里返回到 API 的响应。
@NareshKumar 上面粘贴了 console.log(z) 的结果：
它是有效的 json {"errorCode":0,"errorMsg":"success","result":{"msg":"\u4e70\u5bb6\u5df2","uid":" 104","username":"\u738b\u626d","userphone":"1565777778","address":"\u4e0a\u6d77","price":"5.00","trade_state":"TRADE_SUCCESS"," hk_orderid":"1575524694820"}}
你能告诉我x到底是什么吗？为什么你在 await 中使用 .text？

【解决方案1】：

可能需要查看更多代码，因此如果您从服务器/url 中提取 JSON，请确保响应标头显示为 JSON 数据类型

【讨论】：

我没有直接从服务器中提取，我将其读取为字符串，请参阅 let z = await x.text
