概要

wemosでenebularを叩いてみた。
postで受信ポイントにhttpリクエストを送った。

サンプルコード

#include <ESP8266WiFi.h>
#include <WiFiClientSecure.h>

const char * ssid = "takahatalib";
const char * password = "***";

bool Https_Get_access(String host, String url, String argument) {
    BearSSL::WiFiClientSecure client;
    client.setTimeout(500);
    client.setInsecure();
    const int httpPort = 443;
    const char * host2 = host.c_str();
    if (!client.connect(host2, httpPort))
    {
        Serial.println("connection failed");
        return false;
    }
    client.print(String("POST ") + url + " HTTP/1.1\r\n" 
        + "Host: " + host + "\r\n" 
        + "User-Agent: ESP8266/1.0\r\n" 
        + "x-api-key:test-api-key\r\n"
        + "content-type:application/x-www-form-urlencoded\r\n"
        + "content-length:32\r\n"
        + "Connection: close\r\n"
        + "\r\n"
        + argument + "\r\n"
        + "\r\n");
    unsigned long timeout = micros();
    while (client.available() == 0)
    {
        if (micros() - timeout > 5000000)
        {
            Serial.println(">>> Client Timeout !");
            client.stop();
            return false;
        }
    }
    while (client.available())
    {
        String line = client.readStringUntil('\r');
        Serial.print(line);
    }
    return true;
}
void setup() {
    Serial.begin(115200);
    delay(10);
    Serial.print("Connecting to ");
    Serial.println(ssid);
    WiFi.begin(ssid, password);
    while (WiFi.status() != WL_CONNECTED)
    {
        delay(500);
        Serial.print(".");
    }
    Serial.println("");
    Serial.println("WiFi connected");
    Serial.println("IP address: ");
    Serial.println(WiFi.localIP());
}
void loop() {
    String host = "***.herokuapp.com";
    String url = "/sensordata";
    String argument = "roomname=house1&temperature=25.7";
    Https_Get_access(host, url, argument);
    while(1)
    {
        delay(5000);
    }
}

以上。
