esp8266在发送json对象和重置时崩溃

Question

你好，我正在尝试使用arduinoJson库发送JSON对象。当它是一个小的json对象时，一切都很好，但是当它变大时，esp8266崩溃并重置。我可以看到调试时，它创建json对象，但当它使用ajax POST方法发送它崩溃。在图片中，你可以看到串行监视器，你也可以看到json对象被创建，但是当它发送它时，esp8266崩溃并重新启动串行调试。我认为问题与这行代码有关。可能的问题

esp8266的代码如下:

我发现了导致重置的问题，这是esp8266的看门狗在6秒后重置了它。这意味着我必须重写我的程序，要么在SPIFFS中保存json数组，要么以较小的部分发送。

修复方法是升级到ESP32，因为ESP8266不够快
