java - 如何在java中使用json处理10个数据

Question

你好我有大约 10 个来自数据库的数据，其属性名称相同

 JSONObject json = new JSONObject();
 json.put("text",value1);
 json.put("title",value2);
 json.put("url",value3);

我使用上面的代码，我得到的与此类似

 {"text":"texting is not bad","title":"tesing","url":"http:\/\/www.example.com\/"}
 {"text":"texting is not bad","title":"tesing","url":"http:\/\/www.example.com\/"}
 {"text":"texting is not bad","title":"tesing","url":"http:\/\/www.example.com\/"}
 {"text":"texting is not bad","title":"tesing","url":"http:\/\/www.example.com\/"}

当我在 php 中解析它时，我得到一个 null 值，我不知道 y ..你能告诉我哪里错了...

Answer 1

你的输出应该是这样的才能被解析

 [{"text":"texting is not bad","title":"tesing","url":"http:\/\/www.example.com\/"},
 {"text":"texting is not bad","title":"tesing","url":"http:\/\/www.example.com\/"},
 {"text":"texting is not bad","title":"tesing","url":"http:\/\/www.example.com\/"},
 {"text":"texting is not bad","title":"tesing","url":"http:\/\/www.example.com\/"}]

为此，您应该使用 JSONArray。
