Uncaught SyntaxError: Unexpected token & in JSON at position 1 at JSON.parse (<anonymous> )</anonymous>

Question

我正在尝试解析 JSON 但它一直在返回

Uncaught SyntaxError: Unexpected token & in JSON at position 1
    at JSON.parse (<anonymous>)

VS Code 中的代码如下所示：

var result = '{{ bans }}';
  var res = JSON.parse(result)

但在控制台中它看起来像：

var result = '{'bans': [{'appealable': False, 'banend': 'Fri, 15 Jan 2021 00:00:00 GMT', 'bannedby': 'parker02311', 'banstart': 'Fri, 15 Jan 2021 00:18:58 GMT', 'id': 1, 'images': 'https://cdn.discordapp.com/attachments/642127559600898058/799867505727504464/Roblox_1_15_2021_11_07_09_PM_2.png,https://cdn.discordapp.com/attachments/642127559600898058/799863972915314688/Roblox_1_15_2021_10_53_30_PM_2.png', 'notes': '<p>test</p>', 'reasons': 'Chat Bypassing, Discrimination', 'userid': '17', 'username': 'test'}, {'appealable': False, 'banend': 'Wed, 20 Jan 2021 00:00:00 GMT', 'bannedby': 'parker02311', 'banstart': 'Sat, 16 Jan 2021 05:46:33 GMT', 'id': 2, 'images': 'https://image.prntscr.com/image/DUQMlOEKTuGDHSkvB4NuRQ.png,https://cdn.discordapp.com/attachments/642127559600898058/799874004457488394/unknown.png', 'notes': '', 'reasons': 'Chat Bypassing,Discrimination', 'userid': '202181894', 'username': 'Dagdoubleagaming'}]}';
var res = JSON.parse(result)

我不确定所有 &#39 的来源，因为后端看起来像：

r = requests.get('http://localhost:5001/get/bans', timeout=5)

        if r.status_code == 200:
            jsonre = r.json()
            return render_template('index.html', name=current_user.username, title='Dashboard', breadcrums=True, bans=jsonre)

请求返回：

  "bans": [
    {
      "appealable": false, 
      "banend": "Fri, 15 Jan 2021 00:00:00 GMT",

}

Answer 1

var result = '{{ bans | escapejs }}'

Answer 2

只是在这里拍摄，但我看了一下这里“https://www.w3schools.com/Js/js_json_parse.asp”，我认为这可能有效。 我认为字符串不是 json 格式，这就是您收到错误的原因。

var 结果 = '{"bans"}'; var res = JSON.parse(结果)
