ESP32 作Web服務器 http Server步驟

資料很少。可能是國外網站的。

百度搜基本出來的是這個網站https://www.dfrobot.com/blog-922.html

出來的代碼是：

#include <WiFi.h>
#include <FS.h>
#include <AsyncTCP.h>
#include <ESPAsyncWebServer.h>
 
const char* ssid = "yourNetworkName";
const char* password =  "yourNetworkPassword";
 
AsyncWebServer server(80);
 
void setup(){
  Serial.begin(115200);
 
  WiFi.begin(ssid, password);
 
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi..");
  }
 
  Serial.println(WiFi.localIP());
 
  server.on("/html", HTTP_GET, [](AsyncWebServerRequest *request){
    request->send(200, "text/html", "<p>This is HTML!</p>");
  });
 
  server.begin();
}
 
void loop(){
}

 

發愁：這個庫在哪裏？我怎麼運行？因而我找到了這裏：

裏面使用ESPAsyncWebServer的步驟

以下：

1   安裝：PlatformIO IDE

這裏有詳細教材：https://blog.csdn.net/baimei4833953/article/details/78771611/

2 建立新的工程："PlatformIO Home > New Project"

http://docs.platformio.org/en/latest/ide/vscode.html

 

3 修改配置文件

Add "ESP Async WebServer" to project using Project Configuration File platformio.ini and lib_deps option:

[env:esp32dev]

platform = espressif32

board = esp32dev

framework = arduino

# using the latest stable version

lib_deps = ESP Async WebServer

 

打開main.c

 

 

#include <WiFi.h>
#include <FS.h>
#include <AsyncTCP.h>
#include <ESPAsyncWebServer.h>
 
const char *ssid = "MyESP32AP";
const char *password = "testpassword";
 
AsyncWebServer server(80);
 
void setup(){
  Serial.begin(115200);
 
  WiFi.softAP(ssid, password);
 
  Serial.println();
  Serial.print("IP address: ");
  Serial.println(WiFi.softAPIP());
 
  server.on("/hello", HTTP_GET, [](AsyncWebServerRequest *request){
    request->send(200, "text/plain", "Hello World");
  });
 
  server.begin();
}
 
void loop(){}
