问题描述
我正在尝试将json字符串转换为的JSONArray org.json.JSONArray类,该字符串包含带有正向slah的dateformat,但是由于字符串中包含斜杠,所以出现了以下异常.
I am trying to convert a json string to JSONArray of org.json.JSONArray class, the string contains a dateformat with forward slah, but I am getting the following exception because of the slash included in string.
public static void main(String args[]) throws JSONException{
String jsonString = "[{ID:1, Name:Ann, DOB:14/08/1991}, {ID:2, Name:Vann, DOB:14/08/1992}]";
JSONArray jsonArray = new JSONArray(jsonString);
System.out.println(jsonArray.toString());
}

推荐答案
JSON中的字符串值
字符串应加引号...,包括属性名称.参见 JSON规范:
对象结构表示为一对大括号,包围着零个或多个名称/值对(或成员).名称是字符串.
An object structure is represented as a pair of curly brackets surrounding zero or more name/value pairs (or members). A name is a string.
字符串的表示类似于C系列编程语言中使用的约定.字符串以引号开头和结尾.
The representation of strings is similar to conventions used in the C family of programming languages. A string begins and ends with quotation marks.
JSON中的日期值
JSON不代表date
类型.它必须表示为字符串.有关更多信息,请参见此答案.
Date values in JSON
JSON has no representation for date
type. It must be represented as a string. See this answer for more information.
您可以使用在线JSON验证器来检查其有效性.
You can use online JSON validators to check the validity.
[
{
"ID":1,
"Name":"Ann",
"DOB":"14/08/1991"
},
{
"ID":2,
"Name":"Vann",
"DOB":"14/08/1992"
}
]
但是,我将格式yyyy-mm-dd
用于日期值而不是dd/mm/yyyy
.
However, I would use the format yyyy-mm-dd
for date values instead of dd/mm/yyyy
.
String jsonString =
"[{\"ID\":1,\"Name\":\"Ann\",\"DOB\":\"14/08/1991\"},{\"ID\":2,\"Name\":\"Vann\",\"DOB\":\"14/08/1992\"}]";
