javascript - 如何将此 QueryString 转换为 JS 对象？[节点]

问题描述

我有以下查询字符串，它是有线卡的 IPN，所以我不能修改这个输入，这是我在 POST 中收到的。

我不知道为什么这是作为 text/plain 而不是 application/json 发送的

如您所见，查询参数是 base64 编码的，这是一个问题，因为它包含 + 和 =，如果使用 URLSearchParams 或任何其他转换方法，它们将会中断。

我尝试使用 bodyparser.urlencoded 但这会将“+”转换为“”

我怎样才能在保持 3 个变量不变的同时安全地拆分它

解决方案

如果URL Web APIsearchParams可用，您可以创建一个 URL 并从中 读取。

如果没有，您可以使用 Javascriptssplit()函数使用 limit 参数：

queryString.split('&').map((value) => value.split('=', 2));

如果数组数组不是您想要的，您可以附加其他处理步骤并执行以下操作：

queryString
  .split('&').map((value) => value.split('=', 2))
  .reduce((obj, value) => {
    obj[value[0]] = value[1];
    return obj;
  }, {});
