MockWebServer可以使用本地Json文件作为响应主体吗？

MockWebServer server = new MockWebServer();
server.start();

MockResponse response = new MockResponse()
        .setResponseCode(200)
        .setHeader("Content-Type", "application/json")
        .setBody(readJsonFile("response.json")); // 读取本地的Json文件作为响应主体
server.enqueue(response);

private String readJsonFile(String fileName) throws IOException {
    InputStream inputStream = getClass().getClassLoader().getResourceAsStream(fileName);
    BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
    StringBuilder stringBuilder = new StringBuilder();
    String line;
    while ((line = reader.readLine()) != null) {
        stringBuilder.append(line);
    }
    reader.close();
    return stringBuilder.toString();
}

// 发送网络请求到MockWebServer
// 处理响应逻辑
