mqtt.js vue-router.esm.js?7b9c:1894 ReferenceError: Buffer is not defined at eval (constants.js?1cd0:46:34)

这个错误通常是因为在浏览器中使用了Node.js中的Buffer对象。在浏览器中,没有Buffer对象,因此会导致这个错误。
你可以尝试在代码中使用浏览器可用的替代方法,例如TypedArray或ArrayBuffer。如果你正在使用某个库或框架,可能需要更新该库或框架以适应浏览器环境。
另外,你也可以尝试使用一些适用于浏览器的MQTT客户端库,例如Paho或MQTT.js(使用浏览器版本)。这些库已经针对浏览器做了优化,并且提供了浏览器可用的API和功能。

mqtt.js Buffer is not defined
This error occurs when the `Buffer` object is not available in the environment where `mqtt.js` is being used.
This can happen in modern JavaScript environments like browsers and newer versions of Node.js, as the `Buffer` object has been deprecated and replaced by `Uint8Array` and other typed arrays.
To fix this error, you can try updating the version of `mqtt.js` you are using to a more recent one, which may have updated its dependencies to use `Uint8Array` instead. Alternatively, you can try using a library like `buffer` or `bufferutil` to provide the `Buffer` object in your environment.
