我是新来的Arduino，我不太熟悉它。我不知道为什么客户端不能连接到服务器，我已经看了几个小时了。任何解决这个问题的办法都将大有帮助。
所以我用下面的代码成功地建立了一个服务器。但是…
// server.ino
#include <ESP8266WiFi.h>
#include <ESP8266WebServer.h>
const char* ssid = "WifiName"; // Wifie name
const char* password = "WifiPassword"; // Wifi password
float sensor_value = 0.0;
String Website;
ESP8266WebServer server(80);
void setup(){
Serial.begin(115200);
WiFi.mode(WIFI_AP);
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while(WiFi.status()!=WL_CONNECTED){
Serial.print(".");
delay(500);
}
Serial.println("Server started at port 80.");
Serial.println("WiFi connected.");
Serial.println("IP address: ");
Serial.print("URL=http://");
Serial.println(WiFi.localIP());
server.on("/", handleIndex); //use the top root path report last sensor value
server.on("/update",handleUpdate); // use this route to update sensor value
server.begin();
}
void loop(){
server.handleClient();
}
void handleIndex(){
Website = "<html><body onload ='process()'><div id='div1'>"+ String(sensor_value) +"</div></body></html>";
server.send(200," text/html",Website);
}
void handleUpdate(){
sensor_value = server.arg("value").toFloat();
Serial.println(sensor_value);
server.send(200,"text/plain","Updated");
}
我尝试将客户端连接到服务器，以便它可以向服务器发送数据，但是客户端和服务器之间的连接无法建立，我不知道为什么。我检查了IP地址，它都是正确的，我只是不明白为什么客户端无法连接到服务器
#include <ESP8266WiFi.h>
#include <ESP8266WebServer.h>
#include <HX711.h>
#include "Wire.h"
#define DOUT D5
#define CLK D6
HX711 scale;
const char* ssid = "WifiName";
const char* password = "Wifipassowrd";
float calibration_factor = 107095;
float val_Weight;
const char* host = "192.168.0.167"; // Server host IP.
const int port = 80;
WiFiClient client;
void setup() {
Serial.begin(115200); //set baud rate
Serial.println("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED)
{
delay(500);//millisecond
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected & connect to client");
}
void loop() {
//connect to the server and send the data as URL parameter
if(client.connect(host, port)){
String url = "update?value=";
url+=String(25.0);
client.print(String("GET /") + url + "HTTP/1.1rn" + "Host: " + host + "rn" +
"Connection: closernrn");
delay(10);
Serial.println("Response: ");
while(client.available()){
String line = client.readStringUntil('r');
Serial.print(line);
}
}else{
Serial.println("fail");
}
}
任何帮助将是伟大的谢谢!
检查密码，你有打字错误。
const char* password = "Wifipassowrd";
