我們定義了一個名為ChartGPTConfig的類，它有兩個私有成員變量apiKey和apiUrl，分別表示ChartGPT的API密鑰和API URL。

public class ChartGPTConfig {private final String apiKey;private final String apiUrl;public ChartGPTConfig(String apiKey, String apiUrl) {this.apiKey = apiKey;this.apiUrl = apiUrl;}public String getApiKey() {return apiKey;}public String getApiUrl() {return apiUrl;}
}

簡單調用示例：

public class ChartGPTExample {public static void main(String[] args) {// 創建ChartGPTConfig對象，設置API密鑰和API URLChartGPTConfig config = new ChartGPTConfig("YOUR_API_KEY", "https://api.chartgpt.com/v1/generate");String query = "What is the population of China?"; // 替換為您的查詢try {// 調用ChartGPT APIString response = callChartGPTAPI(config, query);System.out.println("Response: " + response);} catch (IOException e) {e.printStackTrace();}}private static String callChartGPTAPI(ChartGPTConfig config, String query) throws IOException {// 創建OkHttpClient實例OkHttpClient client = new OkHttpClient();// 構建API請求URLString url = config.getApiUrl() + "?query=" + query;// 創建HTTP請求Request request = new Request.Builder().url(url).addHeader("Authorization", "Bearer " + config.getApiKey()).build();// 發送HTTP請求并獲取響應try (Response response = client.newCall(request).execute()) {return response.body().string();}}
}

示例中使用了OkHttp庫來發送HTTP請求，可以通過Maven或Gradle將依賴添加。

Maven引入OkHttp依賴:

<dependency><groupId>com.squareup.okhttp3</groupId><artifactId>okhttp</artifactId><version>4.9.1</version>
</dependency>

Gradle引入OkHttp依賴:

// 其他配置
dependencies {// OkHttpimplementation 'com.squareup.okhttp3:okhttp:4.9.1'
}
