如何在放心的回應中獲取價值

Question

通過使用放心的方式，我得到了如下響應：

{
    "data": {
        "hasMore": true,
        "galleries": [
            {
                "pic": "/xianfu/34b9a6d07bc91a659156d79da1d82f7d18432.jpg",
                "picInZoom": "/xianfu/34b9a6d07bc91a659156d79da1d82f7d18432.jpg@200w"
            },
            {

    },
    "code": 0,
    "msg": "Success"
}

如何用JAVA代碼獲取響應中第一張圖片的價值，非常感謝！

Answer 1

嘗試使用toString（）方法將響應轉換為字符串

然后將該字符串轉換為對象，如下所示：

JSONObject jsonObj = new JSONObject(homeAddress);

從那里，您可以像這樣訪問它：

String pic = jsonObj.getJSONObject("data").getJSONArray("galleries").getJSONObject(0).getString("pic");
