android - 在 adb logcat 输出中格式化 json 字符串

Question

出于记录目的，我打印出 json 响应字符串，并可以在 android“adb logcat”命令中看到它们。有没有办法很好地格式化 adb logcat 输出中的 json 字符串，使其看起来像这样？

{ "code" : "0",
  "text" : "hello world"
} 

Answer 1

您可以使用

JSONObject.toString()

方法在 logcat 上漂亮地打印 JSON。

Log.d("tag", jsonObject.toString(4));

输出

(29124): {
(29124):     "text": "hello world",
(29124):     "code": "0"
(29124): }

Answer 2

我无法在代码中很好地打印 JSON 消息。我只需在 Mac 上双击 LogRabbit 中的消息，它就会漂亮地打印它或突出显示 Base64 来解码它。

完全公开，我是 Mac 版 LogRabbit 的创建者。

Answer 3

您可以使用我的记录器代码以原始形式格式化日志中的json：

Logger.dd("Section label", json);

Answer 4

fastJson提供了方法：

//serialize a prettyFormat json string 

public static final String toJSONString(Object object, boolean prettyFormat);

eg:Log.d(TAG,JSON.toJSONString(object, true));
