在上面的字符串值，我们是从网站的结果值捕获，我们将得到一个字符串格式使用selenium webdriver。这我需要转换和读取"消息"的值

注意:我试过下面的代码

JsonElement jelement = new JsonParser().parse((String) elementText);
JsonObject  jobject = jelement.getAsJsonObject();
jobject.getAsJsonObject("Results");

以上将提供result json的完整结果值，但我需要获取与"Message"一起出现的值

Answer 1

第一行下面通过传递字符串[JSON格式的，它应该是JSON格式的，否则它将通过一个异常]创建JSONObject

在第二行，你现在有一个JSON对象，你可以从中获取任何元素，

e.g to fetch the value for Message, which is an element of "Results" object which is of JSON type, 

可以使用。根据你取的是什么使用get

e.g getString -> for getting String, 
    getInt->for getting Integer, 
    JSONObject-> for getting an JSONObject 
    getJSONArray-> for getting a JSONArray

JSONObject jsonObj=new JSONObject(pass your String) //This converts in to JSON Object
jsonObj.getJSONOObject("Results").getString("Message"); //As result internally itself is a JSON Object
