Question

我从服务器获取了一个JSONArray，它是我发送给服务器的电子邮件的报告。我的目标是通过它，选择一个具有特定主题的那个并打印＆＃34;收到的＆＃34;数组中该元素的数字。 JSON看起来像这样：

[
{"rejections":58,"timestamp":"2014-08-08 12:46:26","subject":"2014/08/08 12:46:03.604: apitest ACTION_100_","clicks":0,"opens":28,"streams":0,"received":86,"bounces":0,"complaints":0,"unsubs":0}
{"rejections":77,"timestamp":"2014-08-11 13:54:49","subject":"2014/08/11 13:54:25.786: apitest ACTION_100_","clicks":0,"opens":14,"streams":0,"received":91,"bounces":0,"complaints":0,"unsubs":0}
]

我基本上试图回应与主题为"recieved":的{{1}}相关联的数字...我不知道如何执行if语句。我知道它看起来像是：

"2014/08/11 13:54:25.786: apitest ACTION_100_"

我的代码：

if(thisElement["subject"].equals("2014/08/11 13:54:25.786: apitest ACTION_100_")){ 
    echo thisElement["recieved"]; 
}`

if (newSubj.equals(obj.get("subject")) {
    int received = obj.getInt("received");
    System.out.println(received);
}

通过Java中的JSONArray
