如何从play框架调用api

// 1. 导入所需的依赖
import play.libs.ws.*;
import javax.inject.Inject;

// 2. 创建API调用的服务类
public class APIService {
    private final WSClient ws;

    @Inject
    public APIService(WSClient ws) {
        this.ws = ws;
    }

    // 3. 配置API调用的参数
    private WSRequest configureRequest(String url) {
        return ws.url(url)
                .setHeader("Content-Type", "application/json")
                .setMethod("GET");
    }

    // 4. 发送API请求
    public CompletionStage<WSResponse> callAPI(String url) {
        WSRequest request = configureRequest(url);
        return request.get();
    }

    // 5. 处理API响应
    public String processResponse(WSResponse response) {
        if (response.getStatus() == 200) {
            return response.getBody();
        } else {
            throw new RuntimeException("API request failed");
        }
    }
}

// 6. 在Play框架中调用API
public class MyController extends Controller {
    private final APIService apiService;

    @Inject
    public MyController(APIService apiService) {
        this.apiService = apiService;
    }

    public CompletionStage<Result> index() {
        String apiUrl = "https://api.example.com/data";
        return apiService.callAPI(apiUrl)
                .thenApply(apiService::processResponse)
                .thenApply(Result::ok);
    }
}
