ESP32 异步网络服务器

Question

我目前正在尝试在 ESP32 上设置异步 Web 服务器。但不幸的是，我没有得到运行的代码。我在 windows 10.

上使用 io 平台

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

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

AsyncWebServer server(80);

setup() 和 loop() 为空。如果我尝试编译代码，就会显示这些消息。

compilation terminated.

Answer 1

您使用了错误的异步 TCP 库。您使用的是 ESP8266，不是 ESP32。

这是它的 PlatformIO 库注册表项：

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

您看到错误是因为它试图调用 ESP8266 上可用的函数，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 platformio.lib 文件以包含此库而不是 ESPAsyncTCP。您可能还需要删除构建或库目录以摆脱旧库。

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"
