#include <iostream>

#include <thread>
#include <vector>
#include <cpprest/http_client.h>
using namespace std;
using namespace web;
using namespace web::http;
using namespace web::http::client;
// Function to simulate data processing and push it to the cloud.

jsonData[U('sensor_id')] = json::value::number(42);
jsonData[U('data')] = json::value::number(data);

clientConfig.set_timeout(chrono::seconds(2)); // 2 seconds timeout.
// Initialize HTTP client.
http_client client(U('http://cloudservice.com/api/data'), clientConfig);
// Make an asynchronous POST request.
client.request(methods::POST, U(''), jsonData.serialize(), U('application/json'))
.then([](http_response response) {
if (response.status_code() == status_codes::OK) {
cout << 'Data pushed to cloud successfully.' << endl;
} else {
cout << 'Failed to push data to cloud. Status code: ' << response.status_code() << endl;
}
}).wait(); // wait for the completion of the request.
}
int main() {
vector<int> sensorData = {11, 75, 30, 42, 55};
for (int data : sensorData) {
cout << 'Processing data: ' << data << endl;
processDataAndPushToCloud(data);
}
cout << 'All sensor data processed.' << endl;
return 0;
}
Code Output:
Processing data: 11
Data pushed to cloud successfully.
Processing data: 75
Data pushed to cloud successfully.
Processing data: 30
Data pushed to cloud successfully.
Processing data: 42
Data pushed to cloud successfully.
Processing data: 55
Data pushed to cloud successfully.
All sensor data processed.
Code Explanation:
This program is a simulation of a real-time system that processes data and sends it to cloud storage. It starts by including necessary headers: iostream for console input/output, chrono and thread for dealing with time and multithreading, vector to store a collection of simulated sensor data, and cpprest for creating HTTP clients and handling requests.
In the processDataAndPushToCloud function, it simulates data processing by making the thread sleep for 100 milliseconds. Then, it prepares a JSON object with a hardcoded sensor ID and the given data value. Next, the HTTP client configuration is set with a 2-second timeout to demonstrate a non-blocking operation which is crucial for real-time implications.
An HTTP client object is created with the URL of the cloud service endpoint. An asynchronous POST request is made with the JSON data serialized and a content type of ‘application/json’. A lambda function then handles the response, checking if the status code is OK (200) to confirm that the data was successfully pushed to the cloud, with appropriate console feedback provided.
In main, a vector of integers simulates sensor data. The program loops through each data point, outputs that it’s being processed, and calls the processDataAndPushToCloud function with the current data point. After that, it prints a message stating that all sensor data was processed, and the program terminates with a return value of zero, indicating successful termination.
