如何使用retrofit将api密钥体附加到post请求的拦截器中

public class ApiKeyInterceptor implements Interceptor {
    private static final String API_KEY = "your_api_key";

    @Override
    public Response intercept(Chain chain) throws IOException {
        Request originalRequest = chain.request();
        HttpUrl originalHttpUrl = originalRequest.url();

        HttpUrl modifiedUrl = originalHttpUrl.newBuilder()
                .addQueryParameter("api_key", API_KEY)
                .build();

        Request modifiedRequest = originalRequest.newBuilder()
                .url(modifiedUrl)
                .build();

        return chain.proceed(modifiedRequest);
    }
}

OkHttpClient client = new OkHttpClient.Builder()
        .addInterceptor(new ApiKeyInterceptor())
        .build();

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("https://api.example.com/")
        .client(client)
        .build();

public interface ApiService {
    @POST("endpoint")
    Call<ResponseBody> postData(@Body RequestBody requestBody);
}

ApiService apiService = retrofit.create(ApiService.class);

// 创建请求体
RequestBody requestBody = RequestBody.create(MediaType.parse("application/json"), "request_body_data");

// 发起POST请求
Call<ResponseBody> call = apiService.postData(requestBody);
call.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
        // 处理响应
    }

    @Override
    public void onFailure(Call<ResponseBody> call, Throwable t) {
        // 处理失败
    }
});
