Arduino mega + esp 8266 发送获取请求 [英] Arduino mega + esp 8266 sending get request
问题描述
我有一个 php 脚本，可以帮助将数据存储到 google firebase 中.
i have a php script which help to store data into google firebase.
我正在使用这个 url 来访问我的 php scipt 并输入数据:arduino.byethost22.com/FirebaseTest.php?slot1_data=empty&slot2_data=occupied
i am using this url to access my php scipt and input the data: arduino.byethost22.com/FirebaseTest.php?slot1_data=empty&slot2_data=occupied
我已经尝试过了，它能够将 slot1_data 存储为空，将 slot2_data 存储为已占用.但是我需要使用 arduino 来发送这个 url.我目前正在使用此代码
i have tried it and it is able to store slot1_data as empty and slot2_data as occupied. However i need to use arduino to send this url. i am using this code currently
#include "SoftwareSerial.h"
#define DEBUG false // turn debug message on or off in serial
String server = "arduino.byethost22.com";
String uri = "/FirebaseTest.php?slot1_data=empty&slot2_data=occupied";
void setup() {
Serial3.begin(115200); //serial3 for esp8266
Serial.begin(115200);
sendData("AT+RST\r\n",2000,DEBUG); // reset module
sendData("AT+CWMODE=3\r\n",1000,DEBUG); // configure as access point
//sendData("AT+CWJAP=\"WifiName\",\"Password\"\r\n",3000,DEBUG);
//delay(20000);
sendData("AT+CIFSR\r\n",1000,DEBUG); // get ip address
sendData("AT+CIPMUX=0\r\n",1000,DEBUG); // configure for single connections
}
void loop() {
Serial3.println("AT+CIPSTART=\"TCP\",\"" + server + "\",80");//start a TCP connection.
if( Serial3.find("OK")) {
Serial.println("TCP connection ready");
}
delay(1000);
String getRequest = "GET " + uri + " HTTP/1.1\r\n" +
"Host: " + server + "\r\n\r\n";
String sendCmd = "AT+CIPSEND=";//determine the number of caracters to be sent.
Serial3.print(sendCmd);
Serial3.println(getRequest.length() );
delay(500);
if(Serial3.find(">")) {
Serial.println("Sending..");
}
Serial3.print(getRequest);
if( Serial3.find("SEND OK")) {
Serial.println("Packet sent");
}
while (Serial3.available()) {
String tmpResp = Serial3.readString();
Serial.println(tmpResp);
}
delay(20000);
}
String sendData(String command, const int timeout, boolean debug)
{
String response = "";
Serial3.print(command); // send the read character to the esp8266
long int time = millis();
while( (time+timeout) > millis())
{
while(Serial3.available())
{
// The esp has data so display its output to the serial window
char c = Serial3.read(); // read the next character.
response+=c;
}
}
//if(debug)
//{
Serial.print(response);
//}
return response;
}
似乎将 get 请求发送到 php 脚本有问题.
it seems that it have problem sending the get request to the php script.
我正在串行监视器中发送数据包，但 Firebase 数据中没有任何变化
i am getting packet sent in the serial monitor but nothing changed in the firebase data
我也收到了

它要求我在浏览器中启用 javascript，但我使用的是 arduino，我该怎么做?当我在谷歌浏览器中输入相同的uri时，数据可以更新
It asked me to enable javascript in my browser, but i am using arduino, how do i do it? When i key in the same uri in google chrome, the data can be updated
我该如何解决这个问题?
how do i solve this problem?
推荐答案
我的代码终于可以工作并在线发送数据了.我改为使用 000webhost 作为我的主机服务器而不是 byethost 并且数据设法更新.
My code finally can work and send data online. i change to use 000webhost as my host server instead of byethost and the data manage to be updated.
我真的不知道为什么，但我猜那个byethost不支持javascript.
i dont really know why but i guess that byethost dont support javascript.
