如何从String中创建包含':','['和']'等字符的Json对象

Question

我有一个字符串,我想从中创建一个jsonobject

import org.json.JSONObject;

JSONObject json=new JSONObject("{success=false, errorMessage=Application with appId : [randomAppId] not registered, errorCode=102}");
System.out.println("JSON:"+json.toString());

但现在我得到的例外,由于字符像:,[,]这是里面的字符串.

堆栈跟踪:

Exception in thread "main" org.json.JSONException: Expected a ',' or '}' at character 53
    at org.json.JSONTokener.syntaxError(JSONTokener.java:410)
    at org.json.JSONObject.<init>(JSONObject.java:222)
    at org.json.JSONObject.<init>(JSONObject.java:402)

Answer 1

问题是,你的字符串是无效的JSON.尝试:

JSONObject json=new JSONObject("{\"success\":false, \"errorMessage\":\"Application with appId : [randomAppId] not registered\", \"errorCode\":102}");
