用大量JavaScript解析JSON [英] Parse JSON with large numbers javascript

问题描述

我从API响应中得到一个 JSON 对象，该对象包含 long 类型值。
由于javascript无法处理64位数字，因此在响应上执行 JSON.parse 时，会将数字四舍五入为javascript可以处理的最大值。

I'm getting a JSON object that includes a long type value from an API response. Since javascript can't handle 64bit numbers, when executing JSON.parse on the response it rounds the number to the maximum value javascript can handle.

API响应：

    {
       "subject": "subjectTitle",
       "longNumberKey": 7356270823847851521,
    }

当将此对象解析为 JSON 时， longNumberKey 的值将为 7356270823847852000 代替 7356270823847851521 。
一种解决方案是将该值表示为 string ，但我无法控制该API的响应。

When parsing this object to JSON, longNumberKey value would be 7356270823847852000 instead of 7356270823847851521. A solution would be to represent this value as a string but I can't control the API response for that.
