How can I create and send JSON file without saving it to disk?
问题
在将 JSON 文件发送给用户之前（通过 Telegram 机器人），我会将其保存到磁盘上。我是否可以直接创建并将 JSON 文件发送给用户，而无需将其保存到磁盘上呢？
private static final String PATH = "./library/";
public static ObjectMapper objectMapper = new ObjectMapper();
public void toJSON(Task task) throws IOException {
String packageName = taskService.getId(task);
String fileName = packageName + ".json";
String pathName = LIBRARY_PATH + fileName;
Path path = Paths.get(pathName);
if (!Files.exists(path)) {
Files.createDirectories(path.getParent());
Files.createFile(path);
}
objectMapper.writeValue(new File(pathName), googlePlayGame);
}
英文:
Before sending JSON file to user (via Telegram Bot) I save it to disk. Can I just create and send JSON file to user without saving it to disk?
private static final String PATH = "./library/";
public static ObjectMapper objectMapper = new ObjectMapper();
public void toJSON(Task task) throws IOException {
String packageName = taskService.getId(task);
String fileName = packageName + ".json";
String pathName = LIBRARY_PATH + fileName;
Path path = Paths.get(pathName);
if (!Files.exists(path)) {
Files.createDirectories(path.getParent());
Files.createFile(path);
}
objectMapper.writeValue(new File(pathName), googlePlayGame);
}

objectMapper.writeValueAsString()将JSON转换为字符串。如果你需要原始字节，还有objectMapper.writeValueAsBytes()。
英文:
objectMapper.writeValueAsString() gives you the JSON as a String. There's also objectMapper.writeValueAsBytes() if you need raw bytes.
