Question

我想使用NodeMCU MCU和自签名证书通过Internet安全地将数据发送到InfluxDB。

我发现这个库似乎可以完成此任务，但是会出现编译错误，更多内容请参见-> https://medium.com/@teebr/iot-with-an-esp32-influxdb-and-grafana-54abc9575fb2

该库似乎仅使用HTTP->我误会了吗？ https://www.arduinolibraries.info/libraries/esp8266-influxdb

使用上述TEEBR的第一个库中的示例，我得到此错误编译-关于如何修复的任何建议？这可以在我的NodeMCU上运行吗？

谢谢

    Serial.println("WiFi connected!");

    influx.authorize(INFLUX_USER,INFLUX_PASS); //if you have set the Influxdb .conf variable auth-enabled to true, uncomment this

    Serial.print("Using HTTPS: ");
    Serial.println(influx.isSecure()); //will be true if you've added the InfluxCert.hpp file.
} 

void loop()
{   
    unsigned long startTime = micros(); //used for timing when to send data next.

    //update our field variables
    float dummy = ((float)random(0, 1000)) / 1000.0;
    count++;

    //write our variables.
    char tags[32];
    char fields[32];

    sprintf(tags,"new_tag=Yes"); //write a tag called new_tag
    sprintf(fields,"count=%d,random_var=%0.3f",count,dummy); //write two fields: count and random_var
    bool writeSuccessful = influx.write(INFLUX_MEASUREMENT,tags,fields);
    if(!writeSuccessful)
    {
        Serial.print("error: ");
        Serial.println(influx.getResponse());
    }

    while ((micros() - startTime) < DELAY_TIME_US)
    {
      //wait until it's time for next reading. Consider using a low power mode if this will be a while.
    }
}

老读者，第一次张贴-感谢您过去的所有帮助！

如何通过ESP8266 / NodeMCU通过Internet和HTTPS将数据写入InfluxDB？
