【问题描述】：

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：

message.json() JSON.stringify(消息) JSON.parse(消息)

【参考方案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);

【讨论】：

很高兴它成功了。尝试使用 Outcomes 数组中的一些元素。

【参考方案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": []
    ]

感谢您的回复。它是如何从服务器返回的。我会尝试在ui上修改它。
