Question

我正在关注tweaking4all（https://www.tweaking4all.nl/hardware/arduino/arduino-ethernet-data-push/）的教程我已经设置了我的sql数据库，并且有一个我正在运行php脚本的站点。当我手动输入将进入我的数据库的变量时，这样的http://apollonian-jacket.000webhostapp.com/add_data.php?serial=288884820500006X&temperature=12.3就可以了。数据将插入数据库中。现在我正在尝试用我的arduino做这个，但它不起作用。这就是我在串口监视器中看到的内容

    Tweaking4All.com - Temperature Drone - v2.0
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

IP Address        : 192.168.0.199
Subnet Mask       : 255.255.255.0
Default Gateway IP: 192.168.0.1
DNS Server IP     : 195.130.131.3
-> Connected
-> Connected
-> Connected
-> Connected

但是当我查看我的数据库时，我看不到任何变化

arduino的代码：

#include <Ethernet.h> // Used for Ethernet

// **** ETHERNET SETTING ****
// Arduino Uno pins: 10 = CS, 11 = MOSI, 12 = MISO, 13 = SCK
// Ethernet MAC address - must be unique on your network - MAC Reads T4A001 in hex (unique in your network)
byte mac[] = { 0x54, 0x34, 0x41, 0x30, 0x30, 0x31 };                                       
// For the rest we use DHCP (IP address and such)

EthernetClient client;
char server[] = "www.apollonian-jacket.000webhostapp.com"; // IP Adres (or name) of server to dump data to
int  interval = 5000; // Wait between dumps

void setup() {

  Serial.begin(9600);
  Ethernet.begin(mac);

  Serial.println("Tweaking4All.com - Temperature Drone - v2.0");
  Serial.println("-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-\n");
  Serial.print("IP Address        : ");
  Serial.println(Ethernet.localIP());
  Serial.print("Subnet Mask       : ");
  Serial.println(Ethernet.subnetMask());
  Serial.print("Default Gateway IP: ");
  Serial.println(Ethernet.gatewayIP());
  Serial.print("DNS Server IP     : ");
  Serial.println(Ethernet.dnsServerIP());
}

void loop() {
  // if you get a connection, report back via serial:
  if (client.connect(server, 80)) {
    Serial.println("-> Connected");
    // Make a HTTP request:
    client.print( "GET /add_data.php?");
    client.print("serial=");
    client.print( "288884820500006X" );
    client.print("&");
    client.print("temperature=");
    client.print( "12.3" );
    client.println( " HTTP/1.1");
    client.print( "Host: " );
    client.println(server);
    client.println( "Connection: close" );
    client.println();
    client.println();
    client.stop();
  }
  else {
    // you didn't get a connection to the server:
    Serial.println("--> connection failed/n");
  }

  delay(interval);
}

我做了很多研究，但一切似乎都是正确的。在此先感谢！

我注意到的第一件事是你正在使用＆＃34; www＆＃34;您的Ardunio代码中的子域名，但不是直接调用时的子域名。似乎www子域未正确映射，因为http://www.apollonian-jacket.000webhostapp.com/review_data.php似乎不起作用。

arduino到php GET请求
