Я использовал Postman для отладки моего PHP POST API, и он работает (игнорируя ввод json против не-json).
<?php
header("Access-Control-Allow-Origin: *");
header("Content-Type: application/json; charset=UTF-8");
//
// include database and object files
require_once '../config/database.php';
require_once '../objects/resdatalog.php';
// instantiate database and resdatalog object
$database = new Database();
$db = $database->getConnection();
// initialize object
$rdl = new Resdatalog($db);
$rdl->Location = $_GET['Location'];
$rdl->Temperature = $_GET['Temperature'];
$rdl->Humidity = $_GET['Humidity'];
$rdl->Pressure = $_GET['Pressure'];
$rdl->RecDate = $_GET['RecDate'];
$rdl->AmbientTemp = $_GET['AmbientTemp'];
$rdl->AmbientHum = $_GET['AmbientHum'];
$rdl->AmbientPressure = $_GET['AmbientPressure'];
$ret=$rdl->insert();
?>
Но клиент должен быть Модуль ESP8266 для мониторинга окружающей среды в различных местах. Я пытался заставить это работать, но отладка только сбила меня с толку. Неважно, что я показываю на стороне клиента, все выглядит нормально. Но, кажется, никогда не попасть на веб-страницу. Я поместил код на веб-странице в «эхо» подтверждения, но в клиенте ничего не появляется. Каков наилучший способ отладки этой настройки:

Connecting the BME280 Sensor:
Sensor -> Board
-----------------------------
Vin (Voltage In) -> 3.3V
Gnd (Ground) -> Gnd
SDA (Serial Data) -> A4 on Uno/Pro-Mini, 20 on Mega2560/Due, 2 Leonardo/Pro-Micro
SCK (Serial Clock) -> A5 on Uno/Pro-Mini, 21 on Mega2560/Due, 3 Leonardo/Pro-Micro

Вот фрагмент последовательного вывода:

11:06:49.892 -> Length: 204
11:06:49.892 -> {"Location": "TiVo Cabinet" , "Temperature" : "73.27" , "Humidity" : "0.00" , "Pressure" : "29.57" , "RecDate" : "2020-04-28 11:06:50" , "AmbientTemp" : "0" , "AmbientHum" : "0" , "AmbientPressure" : "0"}
11:06:49.933 -> receiving from remote server`
