将来自 websocket 消息的字符串响应解析为 JSON

Question

我收到一个 websocket 消息的消息响应，像这样的字符串

odds.1:[{"id":1,"marketType":10,"name":"Double chance","status":"HandedOver","specifiers":"","Outcomes":[ ]},{"id":2,"marketType":11,"name":"平局不下注","status":"HandedOver","specifiers":"","Outcomes":[]},{ "id":3,"marketType":1,"name":"1x2","status":"HandedOver","specifiers":"","Outcomes":[]}]

我想将它解析为这样的 json 数组，但不确定如何...

（注意我也需要删除“odds.1”）

我尝试过但没有奏效的方法：

1. message.json()
2. JSON.stringify(消息)
3. JSON.parse(消息)

Answer 1

一种快速的方法是，

const a = `odds.1:[{"id":1,"marketType":10,"name":"Double chance","status":"HandedOver","specifiers":"","Outcomes":[]},{"id":2,"marketType":11,"name":"Draw no bet","status":"HandedOver","specifiers":"","Outcomes":[]},{"id":3,"marketType":1,"name":"1x2","status":"HandedOver","specifiers":"","Outcomes":[]}]`;

const array = a.split("odds.1:")[1];
const result = JSON.parse(array);
console.log(result);

Answer 2

您的字符串不是正确的 json。它应该包含在 {} 中，关键赔率 .1 必须用双引号括起来，因为

{
    "odds .1": [{
        "id": 1,
        "marketType": 10,
        "name": "Double chance",
        "status": "HandedOver",
        "specifiers": "",
        "Outcomes": []
    }, {
        "id": 2,
        "marketType": 11,
        "name": "Draw no bet",
        "status": "HandedOver",
        "specifiers": "",
        "Outcomes": []
    }, {
        "id": 3,
        "marketType": 1,
        "name": "1x2",
        "status": "HandedOver",
        "specifiers": "",
        "Outcomes": []
    }]
}
