JAVASCRIPT JSON.parse() 返回意外的 JSON 输入结束

Question

我收到来自服务的响应，使用 https

rest.on("data", data => {
  response = JSON.parse(data);
});

我需要解析这个响应，但是......我知道最终结果应该是(我通过 postman 得到的)......

{ "code": 200,
"msg": "",
"data": [
    {
        "id": "t4ba",
        "devData": {
            "id": "bb2as",
            "state": "OK"
        },
        "entries": {
            "2019-05-26T19:03:13.9260000": 15,
            "2019-05-26T19:03:29.1690000": 26,
            "2019-05-26T19:04:16.6880000": 65
        }
    },
    {
        "id": "t4ba-2",
        "devData": {
            "id": "bb2as",
            "state": "Underperformance"
        },
        "entries": {
            "2019-05-26T19:03:13.9260000": 25,
            "2019-05-26T19:03:29.1690000": 45,
            "2019-05-26T19:04:16.6880000": 32
        }
    }
],
"dateResponse": "2021-03-26T19:04:16.6880000" }

当我跑 JSON.parse(数据)
我收到这个错误

"errorType": "SyntaxError","errorMessage": "Unexpected end of JSON input","trace": ["SyntaxError: Unexpected end of JSON input"," at JSON.parse ()"," at IncomingMessage. (/var/task/index.js:47:23)"," at IncomingMessage.emit (events.js:315:20)"," at IncomingMessage.EventEmitter.emit (domain.js:467:12)"," at IncomingMessage.Readable.read (internal/streams/readable.js:519:10)"," at flow (internal/streams/readable.js:992:34)"," at resume_ (internal/streams/readable.js:973:3)"," at processTicksAndRejections (internal/process/task_queues.js:80:21)"]

我认为“数据数组”字段是问题所在，我不知道如何解决。
当我收到带有空数据的响应时:[]，一切正常。

嗯……答案很简单……
开始吧:::::
首先，看起来您从服务中获得了大量数据...
在 response.on("数据"
一开始数据不完整，所以，.on("data""重复自己"从init到结束，那么你的数据就完整了......
代码

res.on("data", data => {
  someVariable += data;
});

然后......在你的 .on("end"

rest.on("end", () => {
  MyJSON = JSON.parse(someVariable);
});

这就是所有的人。
