Before integrating the DataAnalyzer API, ensure you have a React application created. If you haven’t already, you can create one using Create React App:

npx create-react-app my-dataanalyzer-app
cd my-dataanalyzer-app
npm start

Authentication

Authentication is the first step in using the DataAnalyzer API. This section shows how to authenticate your React app with the API.

Step 1: Install Axios

Install Axios to make HTTP requests more manageable. You can use fetch as well, but Axios simplifies some aspects, like setting headers.

npm install axios

Step 2: Create an Authentication Service

Create an AuthService.js to handle API authentication:

import axios from 'axios';

const API_KEY = 'YOUR_API_KEY_HERE'; // Replace with your actual API key
const BASE_URL = 'https://api.dataanalyzer.com/auth';

const authenticate = async () => {
  try {
    const response = await axios.post(BASE_URL, {}, {
      headers: { Authorization: `Bearer ${API_KEY}` }
    });
    return response.data; // Assuming the API returns a token
  } catch (error) {
    console.error("Authentication failed:", error);
    return null;
  }
};

export default authenticate;

Fetching Data

After authenticating, your application can request data analysis reports from DataAnalyzer.

Step 1: Create a Report Service

Create a ReportService.js to fetch reports:

import axios from 'axios';

const BASE_URL = 'https://api.dataanalyzer.com/reports';

const fetchReport = async (reportId, authToken) => {
  try {
    const response = await axios.get(`${BASE_URL}/${reportId}`, {
      headers: { Authorization: `Bearer ${authToken}` }
    });
    return response.data; // Assuming the API returns report data
  } catch (error) {
    console.error("Fetching report failed:", error);
    return null;
  }
};

export default fetchReport;

Authentication

import requests

API_KEY = 'YOUR_API_KEY'
response = requests.post('https://api.dataanalyzer.com/auth', headers={'Authorization': f'Bearer {API_KEY}'})
if response.status_code == 200:
    print("Authentication successful")
    token = response.json()['token']
else:
    print("Authentication failed")

Fetching Data

def fetch_report(token, report_id):
    headers = {'Authorization': f'Bearer {token}'}
    response = requests.get(f'https://api.dataanalyzer.com/reports/{report_id}', headers=headers)
    if response.status_code == 200:
        print("Report data:", response.json())
    else:
        print("Failed to fetch report")

fetch_report(token, 'report_id')

Authentication

HttpClient client = HttpClient.newHttpClient();
HttpRequest request = HttpRequest.newBuilder()
        .uri(URI.create("https://api.dataanalyzer.com/auth"))
        .headers("Authorization", "Bearer YOUR_API_KEY")
        .POST(HttpRequest.BodyPublishers.noBody())
        .build();

HttpResponse<String> response = client.send(request, HttpResponse.BodyHandlers.ofString());

if (response.statusCode() == 200) {
    System.out.println("Authentication successful");
    String token = new JSONObject(response.body()).getString("token");
} else {
    System.out.println("Authentication failed");
}

Fetching Data

HttpRequest reportRequest = HttpRequest.newBuilder()
        .uri(URI.create("https://api.dataanalyzer.com/reports/report_id"))
        .headers("Authorization", "Bearer " + token)
        .GET()
        .build();

HttpResponse<String> reportResponse = client.send(reportRequest, HttpResponse.BodyHandlers.ofString());

if (reportResponse.statusCode() == 200) {
    System.out.println("Report data: " + reportResponse.body());
} else {
    System.out.println("Failed to fetch report");
}
