Question

解析JSON字符串时JSON解析错误

我在JS代码下面有这个，并且给出错误。我想打印engineCode和值吗？

谢谢。

//I have update the code. Sorry about the confusion ...
let a = '{ "car": "Honda", "specs": {"engineCode": 1001} }';
let b = JSON.parse(a);
console.log(b); //prints json
//JSON.parse(b.engineCode); //please ignore this .....
JSON.parse(b.specs); //error while parsing and how to fix??

Answer 1

您无需再次解析，只需使用点符号即可使用

import bs4
import requests
from bs4 import BeautifulSoup


def parsePrice():
    r = requests.get('https://www.finanzen.net/realtimekurs/Apple')
    soup = BeautifulSoup(r.text,"lxml")
    price = soup.find_all('div',{'class':'price'})[0].find('span').text
    return price


while True:
    print("Price:"+str(parsePrice()))

Answer 2

正如其他人已经说过的那样，无需重新解析。考虑到您的JSON，请尝试console.log(b.specs.engineCode)：

{
  "car": "Honda",
  "specs": {
    "engineCode": 1001
  }
}

如果您想真的要b.engineCode，请重构您的JSON以反映以下内容：

{
  "car": "Honda",
  "engineCode": 1001
}

无法理解此JSON分析错误
