Controllers

#NasaApodController

The controllers package contains classes responsible for handling incoming HTTP requests and defining the API endpoints.

@Autowired
private  NasaApodService nasaApodService;

@GetMapping("/apod")
public
List<NasaApodResponse> getAPOD ( @RequestParam(required = false) String date,
                                 @RequestParam(required = false) String start_date,
                                 @RequestParam(required = false) String end_date,
                                 @RequestParam(required = false) Integer count,
                                 @RequestParam(required = false) Boolean thumbs ) {
    return nasaApodService.getAPOD(date, start_date, end_date, count, thumbs);
}

Models

#NasaAPODResponse

The models package includes classes that represent the data structures used in the application, such as APOD objects.

// Constructors
public APODResponse() {
}

// Getters and Setters public String getDate() { return date; }

public void setDate(String date) {
	this.date = date;
}

public String getExplanation() {
	return explanation;
}

public void setExplanation(String explanation) {
	this.explanation = explanation;
}

public String getUrl() {
	return url;
}

public void setUrl(String url) {
	this.url = url;
}

public String getTitle() {
	return title;
}

public void setTitle(String title) {
	this.title = title;
}

public String getMediaType() {
	return mediaType;
}

public void setMediaType(String mediaType) {
	this.mediaType = mediaType;
}

public String getThumbnailUrl() {
	return thumbnailUrl;
}

public void setThumbnailUrl(String thumbnailUrl) {
	this.thumbnailUrl = thumbnailUrl;
}

Services

#NasaApodService

The services package contains classes that handle the business logic of fetching APOD data from the NASA API and processing the requests.

@Value("${nasa.apod.apiKey}")
private String apiKey;  // You can use an application.properties or application.yml file for configuration.

@Value("${nasa.apod.baseUrl}")
private String baseUrl;

private final RestTemplate restTemplate;

public NasaApodService(RestTemplate restTemplate) {
    this.restTemplate = restTemplate;
}

public NasaApodResponse getApodByDate(String date) {
    String apiUrl = baseUrl + "/planetary/apod?api_key=" + apiKey + "&date=" + date;
    return restTemplate.getForObject(apiUrl, NasaApodResponse.class);
}

// Add other methods for different APOD retrieval options (start date, end date, count, etc.)
