こんにちは私はarduino ideをコードに使用していて、WIFIClientの例をGETを使ってローカルホストに送るように変更しました。それは私に悪い要求エラーを与える。任意のヘルプや提案が、私は、これはローカル上でこれを実行している人のために役立つことを願うシリアルモニターから400悪いリクエストarduino esp8266
修正WIFIClinet
#include <ESP8266WiFi.h>
const char* ssid = "ssid";
const char* password = "pwd";
const char* host = "http://10.0.0.39/edu/arduino.php";
void setup() {
Serial.begin(115200);
delay(10);
// We start by connecting to a WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
