ESP8266 GET请求：建立短连接 | Arduino 代码示例

To establish a short connection with an ESP8266 using GET method, you can use the following code:\n\ncpp\n#include <ESP8266WiFi.h>\n#include <ESP8266HTTPClient.h>\n\nconst char* ssid = \"your_SSID\";\nconst char* password = \"your_PASSWORD\";\n\nvoid setup() {\n Serial.begin(115200);\n\n WiFi.begin(ssid, password);\n while (WiFi.status() != WL_CONNECTED) {\n delay(1000);\n Serial.println(\"Connecting to WiFi...\");\n }\n\n Serial.println(\"Connected to WiFi\");\n\n // Establish short connection using GET method\n HTTPClient http;\n http.begin(\"http://your_server_endpoint\"); // Replace with your server endpoint\n int httpCode = http.GET();\n\n if (httpCode > 0) {\n String payload = http.getString();\n Serial.println(payload);\n } else {\n Serial.printf(\"[HTTP] GET request failed, error: %s\n\", http.errorToString(httpCode).c_str());\n }\n\n http.end();\n}\n\nvoid loop() {\n // Your code here\n}\n\n\nMake sure to replace "your_SSID", "your_PASSWORD", and "http://your_server_endpoint" with your actual SSID, password, and server endpoint. This code connects to the specified WiFi network, establishes a short connection with the server using the GET method, retrieves the response payload, and prints it to the Serial Monitor.\n\nNote: This code assumes you have already installed the necessary libraries (ESP8266WiFi and ESP8266HTTPClient) in your Arduino IDE.
