Description:
The fetchUserData() function is designed to asynchronously retrieve user-specific information from a designated remote server endpoint. It uses an HTTP GET request to access the resource and processes the response into a usable data structure, such as a JSON object. This function is typically utilized in applications requiring dynamic data loading for user profiles or account management.

Key Features:

  1. Asynchronous Operation: Implements suspend (Kotlin Coroutines) or async/await (JavaScript-style) to perform the request without blocking the main thread.
  2. Error Handling: Includes exception handling to manage network errors, timeouts, or invalid responses.
  3. Data Parsing: Converts the raw HTTP response into a structured format (e.g., a User model object) for seamless integration within the application.

Example Usage in Kotlin:

kotlin
suspend fun fetchUserData(userId: String): User {
val url = "https://api.example.com/user/$userId"
return withContext(Dispatchers.IO) {
try {
val response = HttpClient.get(url)
if (response.isSuccessful) {
return@withContext response.body<User>()
} else {
throw Exception("Error fetching user data: ${response.status}")
}
} catch (e: Exception) {
throw Exception("Network request failed: ${e.message}")
}
}
}
