如何在Arduino C++中一次上传多个文件到ftp

#include <ESP8266WiFi.h>
#include <ESP8266FtpClient.h>

// WiFi网络设置
const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";

// FTP服务器设置
const char* ftpServer = "your_FTP_SERVER";
const char* ftpUser = "your_FTP_USERNAME";
const char* ftpPassword = "your_FTP_PASSWORD";

void setup() {
  Serial.begin(115200);

  // 连接WiFi网络
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
  Serial.println("Connected to WiFi");

  // 连接FTP服务器
  FtpClient.setDebugSerial(&Serial);
  FtpClient.begin(ftpServer, ftpUser, ftpPassword);
  while (!FtpClient.isConnected()) {
    delay(1000);
    Serial.println("Connecting to FTP server...");
  }
  Serial.println("Connected to FTP server");
}

void loop() {
  // 上传多个文件到FTP服务器
  if (FtpClient.isConnected()) {
    // 上传文件1
    if (FtpClient.put("file1.txt", "/path/to/remote/file1.txt")) {
      Serial.println("File 1 uploaded successfully");
    } else {
      Serial.println("File 1 upload failed");
    }

    // 上传文件2
    if (FtpClient.put("file2.txt", "/path/to/remote/file2.txt")) {
      Serial.println("File 2 uploaded successfully");
    } else {
      Serial.println("File 2 upload failed");
    }

    // 上传文件3
    if (FtpClient.put("file3.txt", "/path/to/remote/file3.txt")) {
      Serial.println("File 3 uploaded successfully");
    } else {
      Serial.println("File 3 upload failed");
    }
  }

  delay(5000); // 间隔5秒钟再次上传
}
