arduion开发esp-12模块

来源：互联网发布：玩客云官方抢购软件编辑：程序博客网时间：2024/05/22 03:10

参考arduion的例子：

预编译：

ESP8266WebServer server ( 8510 ); 监听8510端口，可以自己修改

const char *ssid = "XXXX";
const char *password = "XXX";

setup需要处理的内容：

WiFi.begin ( ssid, password ); 连接Wi-Fi

server.onNotFound ( handleNotFound ); 注册出错处理函数

server.on ( "/", handleRoot ); 注册处理函数

server.begin();

loop函数需要处理的内容：

server.handleClient(); 开始监听

其它：

code：状态代码如：200， 404， 500等

type：网页类型如：text/html，image/svg+xml等

message：要发给客户端的内容

server.send ( code, type, message );

server.args(); 获取参数个数

获取参数名称和参数值：

for ( uint8_t i = 0; i < server.args(); i++ ) {
message += " " + server.argName ( i ) + ": " + server.arg ( i ) + "\n";

}

源码：

#include <ESP8266WiFi.h>

#include <WiFiClient.h>
#include <ESP8266WebServer.h>
#include <ESP8266mDNS.h>

const char *ssid = "XXXX";
const char *password = "XXX";

ESP8266WebServer server ( 8510 );

const int led = 13;

void handleRoot() {
digitalWrite ( led, 1 );
char temp[400];
int sec = millis() / 1000;
int min = sec / 60;
int hr = min / 60;

snprintf ( temp, 400,

hr, min % 60, sec % 60

server.send ( 200, "text/html", temp );
digitalWrite ( led, 0 );

String message = "File Not Found\n\n";
message += "URI: ";
message += server.uri();
message += "\nMethod: ";
message += ( server.method() == HTTP_GET ) ? "GET" : "POST";

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 ( 115200 );
WiFi.begin ( ssid, password );
Serial.println ( "" );

// Wait for connection
while ( 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 ( "esp8266" ) ) {
Serial.println ( "MDNS responder started" );
}

server.on ( "/", handleRoot );
server.on ( "/test.svg", drawGraph );
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();
}

void drawGraph() {
String out = "";
char temp[100];
out += "<svg xmlns=\"http://www.w3.org/2000/svg\" version=\"1.1\" width=\"400\" height=\"150\">\n";
out += "<rect width=\"400\" height=\"150\" fill=\"rgb(250, 230, 210)\" stroke-width=\"1\" stroke=\"rgb(0, 0, 0)\" />\n";
out += "<g stroke=\"black\">\n";
int y = rand() % 130;
for (int x = 10; x < 390; x+= 10) {
int y2 = rand() % 130;
sprintf(temp, "<line x1=\"%d\" y1=\"%d\" x2=\"%d\" y2=\"%d\" stroke-width=\"1\" />\n", x, 140 - y, x + 10, 140 - y2);
out += temp;
y = y2;
}
out += "</g>\n</svg>\n";

server.send ( 200, "image/svg+xml", out);
