如何使用JSON.org/java库解析JSON文件？

我的输出是不同的，它们看起来很奇怪

File f = new File("output.json");

FileReader fr = new FileReader(f);

BufferedReader br = new BufferedReader(fr);

StringBuffer sb = new StringBuffer();

String eachLine = br.readLine();

while (eachLine != null) {

   sb.append(eachLine);

   eachLine = br.readLine();

}

String readFile = sb.toString();

System.out.println("output = "+readFile);

JSONObject output = new JSONObject(readFile);

System.out.println("output jsonobject = "+output.toString());

output={“responseData”：{“results”：[{“GsearchResultClass”：“GimageSearch”，“width”：“402”，“height”：“604”，“imageId”：“和9gctrnhp9d5splswoft8cr5fsq-A6wsk0dorj6hremguffgmouivbz”，“tbWidth”：“90”，“tbHeight”：“135”，“unscapedurl”：http://www.24dhakanews.com/wp-content/uploads/2011/04/prova05.jpg“，“url”："http://www.24dhakanews.com/wp-content/uploads/2011/04/prova05.jpg“，”visibleUrl:“www.24dhakanews.com”，“title:“\u003cb\u003eProva\u003c/b\u003e视频是做生意用的\u0026lt；！--DONTREWRITE--\u0026gt；«电影«达卡\u003cb\u003e…\u003c/b\u003e”，“标题信息”：”Prova视频是用于做生意的\u0026lt；！--DONTREWRITE--\u0026gt；«电影«达卡…，“原始环境”：http://www.24dhakanews.com/film/prova-video-is-for-doing-business.php，“内容”：“日期是\u003cb\u003eProva\u003c/b\u003e丑闻。”，“内容格式”：“日期是Prova丑闻。”，“tbUrl”：http://images.google.com/images?q\u003dtbn:AND 9GCTRNHP9D5SPLSWOOFTORF8CR5FSQ-A6TWSk0Dorj6HrEmgUFFGMoUivBZ:www.24dhakanews.com/wp content/uploads/2011/04/prova05.jpg]，“游标”：{“页面”：[{“开始”：“0”，“标签”：1}，{“开始”：“1”，“标签”：2}，{“开始”：“标签”：3}，{“开始”：“3”，“标签”：4}，{“开始”：“4”，“标签”：5”，“开始”，“开始”：“{6”：标签：7}，{“开始”：“7”，“标签”：8}]，“估计结果计数”：“19400000”，“currentPageIndex”：0，“moreResultsUrl”：http://www.google.com/images?oe\u003dutf8\u0026ie\u003dutf8\u0026source\u003duds\u0026start\u003d0\u0026hl\u003den\u0026q\u003dprova“}，“响应详细信息”：null，“响应状态”：200}

第一个打印输出有转义字符，第二个没有

在第二次打印输出中，您将返回的JSON字符串文本解析为JSON对象，然后将其转换为字符串

您的第一份打印输出：

你的第二次大奖赛：

"moreResultsUrl":"http://www.google.com/images?oe\u003dutf8\u0026ie\u003dutf8\u0026source\u003duds\u0026start\u003d0\u0026hl\u003den\u0026q\u003dprova"

你可以试试这个。

我的问题是第一个输出是这个

output jsonobject={“responseData”：{“cursor”：

但是第二个是这个

output jsonobject={“responseData”：{“cursor”：{

我会试试解析器。{谢谢
