java - 如何在 Android 上用 Java 解析格式错误的 Json？

Question

所以我有一个 Jsonobject，它是我的服务器以下列格式作为响应得到的:

{"SubjectName":["Irish"],"BookName":["Bun Go Barr 1"]}{"WorksheetID":[5],"WorksheetName":["TESTS"]}

通常为了获得结果，我会简单地按以下方式对对象内的特定数组进行基本循环:

try {
            jsonArray = jsonObject.getJSONArray("SubjectName");
        } catch (JSONException e) {
            e.printStackTrace();
        }
        BookSubject = new String[jsonArray.length()];
        for (int i = 0; i < jsonArray.length(); i++) {
            try {
                BookSubject[i] = jsonArray.getString(i);
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }

然而，在这种情况下似乎有一个额外的“{”分隔一些数组，这意味着当我尝试对工作表 ID 执行此操作时，我在 logcat 中得到以下内容:

有人知道我怎样才能把它捡起来吗？

Answer 1

您的 json 无效。

可以测试json在线工具http://www.jsoneditoronline.org/

改变形式:

{"SubjectName":["Irish"],"BookName":["Bun Go Barr 1"]}{"WorksheetID":[5],"WorksheetName":["TESTS"]}

收件人:

[
  {
    "SubjectName": "Irish",
    "BookName": "Bun Go Barr 1"
  },
  {
    "WorksheetID": 5,
    "WorksheetName": "TESTS"
  }
]
