java - org.json.JSONException) org.json.JSONException : JSONObject ["routes"] not found

转载作者：行者123 更新时间：2023-11-30 05:30:24

我有 7 个协议(protocol)，我想在网站上显示。但该网站仅显示 4 个协议(protocol)，尽管 JSON 文件中有 7 个协议(protocol)。我决定用调试器检查一下，它通过了 4 个协议(protocol)，没有错误。但是从第五个协议(protocol)开始，就出现了这样的错误。

我有错误

org.json.JSONException) org.json.JSONException: JSONObject["routes"] not found.

最佳答案

好的，这个问题是因为在 JSON 对象中找不到 routes 字段，那么你需要检查 JSON 对象是否有这个字段，我创建了一个名为 getRoutesAsJSONObject(JSONObject jsonObject) 的方法)此方法检查 JSON 对象是否有路由，然后将路由作为 JSON 对象返回，否则创建一个 JSON 对象并将路由添加为 JSONObject，并将导入、导出和首选值设置为 0。
