java - 将字符串转换为 JSON 时未终止的对象

Question

我正在使用 Android Studio，我有一个字符串变量，称为 sResponse(如下)。根据调试器，它具有以下值:

 {
    "responseData": {
    "emotion":"",
    "lastinput":{actionResult={"value":{"label":"green","key":"1"},"result":"success","action":"displayClickableList"},
    "answer":"Sorry, I did not understand.",
    "link": {
    "href":"",
    "target":""
    },
    "extraData": {

    },
    "responseSession": {
    "id":"c4a5ef257851a991eb32c69132c9",
    "transaction":"4"
    },
    "responseDetails": "null",
    "responseStatus": "200",
    "applicationUrl": "http://noki-dev.cloud.com:90/moto-1/"
    }
    }

当我尝试以这种方式用它初始化一个 JSONObject 时:

jResponse=new JSONObject(sResponse);

...我的 Logcat 中出现以下异常:

>>>>>>>>>Thread EXCEPTION1: Response with invalid JSON format: , FrontendActivity.java L:421 ***** *org.json.JSONException: Unterminated object at character 502 of : sResponse

我怀疑 URL 中的那些//造成了麻烦。我不是转义 JSON 字符的专家。如何从先前的字符串中获取有效的 JSONObject？您能从我的方法中发现什么问题？

由于 actionResult 附近的 = 符号以及 actionResult 没有用双引号引起来的问题，并且您没有关闭 json 字符串

将 Json 字符串替换为:

{
    "responseData": {
    "emotion":"",
    "lastinput":{"actionResult":{"value":{"label":"green","key":"1"},"result":"success","action":"displayClickableList"},
    "answer":"Sorry, I did not understand.",
    "link": {
    "href":"",
    "target":""
    },
    "extraData": {

    },
    "responseSession": {
    "id":"c4a5ef257851a991eb32c69132c9",
    "transaction":"4"
    },
    "responseDetails": "null",
    "responseStatus": "200",
    "applicationUrl": "http://noki-dev.cloud.com:90/role-va-1/"
    }
    }
}

并在字符串末尾添加}。
