Arduino Can'；t从esp8266接收数据,arduino,esp8266,arduino-esp8266,esp8266wifi,Arduino,Esp8266,Arduino Esp8266,Esp8266wifi,我试图使用esp8266和aruino uno从HTML页面接收密码，在代码中，串行监视器读取信息，如果正确，则闪烁led，但我无法正确接收此信息这里是esp8266的代码，其中是HTML页面、密码请求和服务器 #include <ESP8266WiFi.h> #include <ESP8266WebServer.h> // WiFi network const char* ssid = "Rede Wi-Fi de Leonard"; c

我试图使用esp8266和aruino uno从HTML页面接收密码，在代码中，串行监视器读取信息，如果正确，则闪烁led，但我无法正确接收此信息

这里是esp8266的代码，其中是HTML页面、密码请求和服务器

#include <ESP8266WiFi.h>
#include <ESP8266WebServer.h>

// WiFi network
const char* ssid     = "Rede Wi-Fi de Leonard";
const char* password = "a01051970c";
ESP8266WebServer server ( 80 );
char htmlResponse[3000];
void handleRoot() {
 snprintf ( htmlResponse, 3000,
"<!DOCTYPE html>\

  server.send ( 200, "text/html", htmlResponse );  
}
void handleSave() {

 Serial.println(ssid);

   Serial.print(".");

 Serial.println("");
 Serial.println("WiFi connected");  
 Serial.println("IP address: ");
 Serial.println(WiFi.localIP());
 server.on ( "/", handleRoot );
 server.on ("/save", handleSave);
 server.begin();
 Serial.println ( "HTTP server started" );
}
void loop() {

}

谢谢大家的支持

在比较之前，请尝试

stringComplete.trim（）

。它将删除\r\n

String inputString = "";         // a String to hold incoming data
bool stringComplete = false;  // whether the string is complete
void setup() {
 // initialize serial:
 Serial.begin(115200);
 // reserve 200 bytes for the inputString:
 inputString.reserve(200);
 pinMode(13,OUTPUT);
}
void loop() {
 // print the string when a newline arrives:
 if (stringComplete) {
   if (inputString=="123456")
  {
      digitalWrite(13,HIGH);
      delay(300);
      digitalWrite(13,LOW);
      Serial.println(inputString);
      // clear the string:
      inputString = "";
     stringComplete = false;
   }
 }
}
void serialEvent() {
 while (Serial.available()) {
   // get the new byte:
   char inChar = (char)Serial.read();
   // add it to the inputString:
   inputString += inChar;
   // if the incoming character is a newline, set a flag so the main loop can
   // do something about it:
   if (inChar == '\n') {
     stringComplete = true;
   }
 }
}
