我有以下几点 result String

{
   "html_attributions" : [],
   "result" : {
      "opening_hours" : {
         "open_now" : true,
         "weekday_text" : [
            "Monday: 8:00 AM â 7:00 PM",
            "Tuesday: 8:00 AM â 7:00 PM",
            "Wednesday: 8:00 AM â 2:30 PM",
            "Thursday: 8:00 AM â 7:00 PM",
            "Friday: 8:00 AM â 7:30 PM",
            "Saturday: 8:00 AM â 6:00 PM",
            "Sunday: Closed"
         ]
      }
   },
   "status" : "OK"
}

我把它转换成 JSONObject 使用

JSONObject resultJSON = new JSONObject(result);

weekday_text 键,但似乎最终输出不在 UTF-8 \u2013

System.out.println(resultJSON.getJSONObject("result").getJSONObject("opening_hours").getJSONArray("weekday_text").toString());

["Monday: 8:00 AM \u2013 7:00 PM","Tuesday: 8:00 AM \u2013 7:00 PM","Wednesday: 8:00 AM \u2013 2:30 PM","Thursday: 8:00 AM \u2013 7:00 PM","Friday: 8:00 AM \u2013 7:30 PM","Saturday: 8:00 AM \u2013 6:00 PM","Sunday: Closed"]

我错过了什么?

您看到unicode转义序列是因为 toString

实际的字符串仍然没有被替换。在数组中打印单个字符串不会显示转义序列:

System.out.println(resultJSON.getJSONObject("result").getJSONObject("opening_hours").getJSONArray("weekday_text").getString(0));

您可以使用OutputStreamWriter来管理输出编码。

JSONObject resultJSON = new JSONObject(result);    
ByteArrayOutputStream out = new ByteArrayOutputStream();
OutputStreamWriter writer = new OutputStreamWriter(out, "utf-8");
resultJSON.write(writer);
writer.flush();

String jSONStringUTF8 = new String(out.toByteArray(),"utf-8");
JSONObject newJSON = new JSONObject(jSONStringUTF8);
String value = newJSON.getString("content");
