[提问]Qt Json数据 如何打印 使其格式化？ [复制链接]

       QJsonDocument doc;
        doc.setObject(QJsonObject);
        QByteArray request_body = doc.toJson();

   qDebug()<<request_body ;

我用以上方式打印Json ， 格式太乱了， 不好阅读， 答应出来格式如下


receive data : "{\n    \"code\": 0,\n    \"data\": {\n        \"homeworks\": [\n            {\n                \"amend_times\": 0,\n                \"answer_right_nums\": 5,\n                \"answer_wrong_nums\": 0,\n                \"first_submit_time\": \"--\",\n                \"last_submit_time\": \"--\",\n                \"paper_number\": \"2889000\",\n                \"score\": 100,\n                \"status\": 40,\n                \"student\": {\n                    \"display_name\": \"小明同学\",\n                    \"mobile\": \"15210608504\",\n                    \"real_name\": \"小明同学\",\n                    \"student_avator\": \"m/icon%2F1517887868078tuWDBimage1517887859468.jpg\",\n                    \"user_id\": \"341097\"\n                },\n                \"student_number\": \"341097\"\n            },\n            {\n                \"amend_times\": 0,\n                \"answer_right_nums\": 5,\n                \"answer_wrong_nums\": 0,\n                \"first_submit_time\": \"--\",\n                \"last_submit_time\": \"--\",\n                \"paper_number\": \"2889169\",\n                \"score\": 0,\n                \"status\": 40,\n                \"student\": {\n                    \"display_name\": \"豪爵吸金ing\",\n                    \"mobile\": \"186100\",\n                    \"real_name\": \"豪爵吸金ing\",\n                    \"student_avator\": \"uncs.com/icon%2F1517799797776Ktdxuweb.png\",\n                    \"user_id\": \"663137\"\n                },\n                \"student_number\": \"663137\"\n            }\n        ]\n    },\n    \"msg\": \"succ\",\n    \"pager\": {\n        \"count\": 2,\n        \"page_num\": 0,\n        \"page_size\": 10000\n    }\n}\n"
"获取学生作业列表"  doRequest receive data : "{\n    \"code\": 0,\n    \"data\": {\n        \"homeworks\": [\n            {\n                \"amend_times\": 0,\n                \"answer_right_nums\": 5,\n                \"answer_wrong_nums\": 0,\n                \"first_submit_time\": \"--\",\n                \"last_submit_time\": \"--\",\n                \"paper_number\": \"2887623\",\n                \"score\": 100,\n                \"status\": 40,\n                \"student\": {\n                    \"display_name\": \"小明同学\",\n                    \"mobile\": \"15210608504\",\n                    \"real_name\": \"小明同学\",\n                    \"student_avator\": \"uWDBimage1517887859468.jpg\",\n                    \"user_id\": \"341097\"\n                },\n                \"student_number\": \"341097\"\n            },\n            {\n                \"amend_times\": 0,\n                \"answer_right_nums\": 5,\n                \"answer_wrong_nums\": 0,\n                \"first_submit_time\": \"--\",\n                \"last_submit_time\": \"--\",\n                \"paper_number\": \"2889165\",\n                \"score\": 100,\n                \"status\": 40,\n                \"student\": {\n                    \"display_name\": \"豪爵吸金ing\",\n                    \"mobile\": \"18610042411\",\n                    \"real_name\": \"豪爵吸金ing\",\n                    \"student_avator\": \"%2F1517799797776Ktdxuweb.png\",\n                    \"user_id\": \"663137\"\n                },\n                \"student_number\": \"663137\"\n            }\n        ]\n    },\n    \"msg\": \"succ\",\n    \"pager\": {\n        \"count\": 2,\n        \"page_num\": 0,\n        \"page_size\": 10000\n    }\n}\n"

如何使其格式化  参考下面的方法

1. QByteArray QJsonDocument::toJson(JsonFormat format = Indented) const  

其中，format主要有两种格式，一种是人们可读的格式，一种是紧凑的格式。分别描述如下表：

Constant	Value	Description
QJsonDocument::Indented	0	定义人们可读的输出格式，如下： { "Array":[ true, 999, "string" ], "key": "value", "null": null }
QJsonDocument::Compact	1	定义一个紧凑的输出格式，如下：
