            "phone": {

                "home": "00 000000",
                "office": "00 000000"
            }
    },
    {
            "id": "c2012",
            "name": "Eminem",
            "email": "eminem@gmail.com",
            "address": "xx-xx-xxxx,x - street, x - country",
            "gender" : "male",
            "phone": {
                "mobile": "+91 0000000000",
                "home": "00 000000",
                "office": "00 000000"
            }
    }
]
}

我正在使用org.json库。

但是当我将json转换为字符串时会出现很多斜杠。

像这样：

 {
            \"id\": \"c200\",
            \"name\": \"Ravi Tamada\",
            \"email\": \"ravi@gmail.com\",
            \"address\": \"xx-xx-xxxx,x - street, x - country\",
            \"gender\" : \"male\",
            \"phone\": {
                \"mobile\": \"+91 0000000000\",
                \"home\": \"00 000000\",
                \"office\": \"00 000000\"
            }
        }

如何摆脱斜线。

Answer 1

我记得，\字符正在逃避＆＃34;。它应该在那里。您想如何使用JSON数据？如果你能为你正在做的事情提供示例代码，那将是很好的。在我的应用程序中，我执行以下操作，

BufferedReader reader = new BufferedReader(new 
    InputStreamReader(response.getEntity().getContent(), "UTF-8"));
String json = reader.readLine();
JSONTokener tokener = new JSONTokener(json);
JSONObject JSONParams = new JSONObject(tokener);
String param1 = eventParams.getString("param1");
...

如果你使用这些对象，他们应该为你删除转义字符。

如果您要将POJO转换为 JSON 表示，

Flexjson 也是一种非常方便的方式。

JSONSerializer将序列化，JSONDeserializer将执行相反的操作。

我自己用过它。

Link to Flexjson Website - http://flexjson.sourceforge.net/

public String doSomething( Object arg1, ... ) {

    Person p = ...load a person...;

    JSONSerializer serializer = new JSONSerializer();
    return serializer.serialize( p );
}

{
    "class": "Person",
    "name": "William Shakespeare",
    "birthday": -12802392000000,
    "nickname": "Bill"
}
