有效的 json 字符串但无法解析
[英]valid json string but cannot parse
问题描述
my environment is nodejs
我的环境是 nodejs
let z = await x.text();
console.log(z)
let y = JSON.parse(z)
the console log is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 token in JSON at position 0
when I copy the json string and paste it to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"}}')
inside browser console浏览器控制台内
the parsing is correct解析正确
edit: someone asks about the json, actually the json is exactly what I pasted above编辑：有人询问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"
}
}
this is also the output of console.log(z)这也是 console.log(z) 的输出
below are some further logs, note that only the last one has an exception下面是一些进一步的日志，注意只有最后一个有异常
