Javascript HTTP POST 输入 JSON 错误

Question

我正在尝试将 JSON 请求添加到 HTTP POST javascript 代码中，如下所示。请参阅下面的代码。

我的问题是，我需要输入以下格式的 JSON 并发送它。但是，我收到 Uncaught SyntaxError: Unexpected token : 您能否建议一下，下面的代码中的 JSON 格式有什么问题？

Sample JSON format to be sent=> {"records":[{"value":{"foo":"bar"}}]}

代码:

function savedata() {

    var membernameStr = parseInt(document.getElementById("MemberID").value).toString();
    var data = JSON.stringify({


        "records": [["value":{"MemberID":membernameStr,"MemberName":"Anna", "AccountNo":"7623", "Address":"Peter", "AccountType":"Peter"}]]

    });
    var xhr = new XMLHttpRequest();
    xhr.addEventListener("readystatechange", function () {
        if (this.status == 200) {
            console.log(this.responseText);

            // Based on successful response, call next POST API.
            var xhr1 = new XMLHttpRequest();
            xhr1.open("POST", "http://localhost:3500");
            xhr1.send(data);

        }
    });
    xhr.open("POST", "http://localhost:8082/topics/topictest");
    xhr.setRequestHeader("Content-Type", "application/vnd.kafka.json.v2+json; charset=utf-8");
    xhr.setRequestHeader("Accept", "application/vnd.kafka.v2+json; charset=utf-8");
    xhr.send(data);
}

您的 JSON 语法不正确，请查看下面的 JSON:

{
  "records": [
    [
      {
        "value": {
          "MemberID": membernameStr ,
          "MemberName": "Anna",
          "AccountNo": "7623",
          "Address": "Peter",
          "AccountType": "Peter"
        }
      }
    ]
  ]
}
