ESP32 AsyncWebServer

Question

我当前正在尝试在ESP32上设置异步Web服务器。但不幸的是，我不能让代码运行。我是Windows10上的usign platform io。

#include <Arduino.h>
#include <ESPAsyncWebServer.h>

const char* ssid = "myAP";
const char* password = "123456789";

AsyncWebServer server(80);

setup()和loop()为空。如果我试图编译代码，这些消息就会出现。

compilation terminated.

Answer 1

您正在使用错误的异步TCP库。您使用的是ESP8266，而不是ESP32。

下面是它的PlatformIO库注册表项：

https://platformio.org/lib/show/305/ESPAsyncTCP

​

​

您会看到错误，因为它试图调用ESP8266上而不是ESP32上可用的函数。

您需要AsyncTCP库：

https://platformio.org/lib/show/1826/AsyncTCP

您应该更新您的platformio.lib文件以包含该库，而不是ESPAsyncTCP。您可能还需要删除build或library目录，以清除旧库。

有同样的问题，降级PlatformIO的核心为我解决了这个问题。

pip安装-U "platformio<4.2.0“
