【Ardiuno】实验ESP32单片机完成搭建简易Web服务器功能（图文）

本文主要是介绍【Ardiuno】实验ESP32单片机完成搭建简易Web服务器功能（图文），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

今天，小飞鱼继续来测试使用ESP32来实现简易的wifi无线web服务器功能。使用Ardiuno平台编辑器输入以下示例代码：

#include <WiFi.h>
#include <WiFiClient.h>
#include <WebServer.h>
#include <ESPmDNS.h>const char* ssid = "XIAOFEIYU";
const char* password = "XIAOFEIYU666";WebServer server(80);const int led = 13;void handleRoot() {digitalWrite(led, 1);server.send(200, "text/plain", "Hello from ESP32! --- XIAOFEIYU");digitalWrite(led, 0);
}void handleNotFound() {digitalWrite(led, 1);String message = "File Not Found\n\n";message += "URI: ";message += server.uri();message += "\nMethod: ";message += (server.method() == HTTP_GET) ? "GET" : "POST";message += "\nArguments: ";message += server.args();message += "\n";for (uint8_t i = 0; i < server.args(); i++) {message += " " + server.argName(i) + ": " + server.arg(i) + "\n";}server.send(404, "text/plain", message);digitalWrite(led, 0);
}void setup(void) {pinMode(led, OUTPUT);digitalWrite(led, 0);Serial.begin(9600);WiFi.mode(WIFI_STA);WiFi.begin(ssid, password);Serial.println("");// Wait for connectionwhile (WiFi.status() != WL_CONNECTED) {delay(500);Serial.print(".");}Serial.println("");Serial.print("Connected to ");Serial.println(ssid);Serial.print("IP address: ");Serial.println(WiFi.localIP());if (MDNS.begin("esp32")) {Serial.println("MDNS responder started");}server.on("/", handleRoot);server.on("/inline", []() {server.send(200, "text/plain", "this works as well");});server.onNotFound(handleNotFound);server.begin();Serial.println("HTTP server started");
}void loop(void) {server.handleClient();delay(2); 
}

编译上传程序到ESP32开发板，查看串口监视器输出，得到开发板获取的ip地址

打开浏览器，输入开发板连接wifi获取的ip地址，可以看到有网页内容显示出来，我们的简易web服务器可以工作了。
