某个在线学习网站提交学习进度的方式

没到月底，领导要求我们完成公司网站的学习进度，于是想搞清楚这个在线学习网站更新学习进度的方法，可以快速更新学习进度，算是解决了学习任务的紧迫性。

一开始看到一个按键，当学习快结束是，网站会提示”我已学完此知识“。我找到这个按键对应的函数：

//提交完成(实时获取)
function completedStudy() {
    var actualSchedule = GetCurSchedule();
    //var arr = '{"orgID":"' + orgID + '","userID":"' + userID + '","knowledgeID":"' + key + '","packageID":"' + packageID + '","masterID":"' + masterID + '","masterType":"' + masterType + '","pageSize":' + pageSize + ',"studySize":' + studySize + ',"studyChapterIDs":"' + stuChpIDs + '","type":' + type + '}';
    var arr = '{"OrgID":"' + orgID + '","UserID":"' + userID + '","KnowledgeID":"' + key + '","PackageID":"' + packageID + '","MasterID":"' + masterID + '","MasterType":"' + masterType + '","PageSize":' + pageSize + ',"StudyTime":-1,"studyChapterIDs":"' + stuChpIDs + '","Type":' + type + ',"IsOffLine":false,"DeviceId":"","IsEnd":true,"ReqType":0,"IsCare":true}';
    var domainurl="";
    if(orgID=="640e03a9-e0e9-49e8-950b-9fddead1203a"||orgID=="a4a97176-c2b2-4583-a585-4a89e22feaf5"||orgID=="3a2732da-f3a5-4856-9f6c-5e36c026555e"||orgID=="45df3843-88f0-4b2b-a9ec-43223007d5c0")
    {
        domainurl="http://api-qida1.yunxuetang.cn/v1/";
    }else{
        domainurl='https://api-qidatestin.yunxuetang.cn/v1/';
    }
    $.ajax({
        type: "POST",
        url: domainurl+"study",
        data: arr,
        headers: {
            "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
            "Source": 501
           // "key": "ba257d05-5eff-4be8-8db0-738bc0cabd67"
        },
        contentType: "application/json",
        dataType: "text",
        success: function (result) {
            if (result == "") {
                $('#divCheat').hide();
                $("#divProcessArea").show();
                $("#ScheduleText").show();
                $("#divNotStartArea").hide();
                $("#divCompletedArea").show();
                $("#divStartArea").hide();
                //即刻显示
                if (initiativeCreditMode == 0 && getCreditMode == 0 && standardStudyScore > 0) {
                    $("#spanFinishScore").show();
                    $("#spanActCmpScore").text(standardStudyScore);
                    $("#spanTalCmpScore").text(standardStudyScore);
                }
                if ($('#icon' + key)) {
                    $('#icon' + key).prop("class", "pic2");
                    iscurfinish = 1;
                }
                actualStudyHours = standardStudyHours;
                studySize = pageSize;
                MinuteChange(100);
                isHere = 1;
                clearInterval(timer);
                clearInterval(timecheck);
            } else {
                //那么返回的是知识名称
                CheatWarming(result);
            }
        },
        error: function (result) {
             var msg=eval("("+xhr.responseText+")")
            CheatWarming(msg.error.message);
        }
    });
}

我在firefox的控制台执行 completedStudy()，进度条的百分百真的一下子变成100%了，但是刷新学习历史列表，发现课程的学习并没有完成，还是0%，刷新学习页面，学习的进程也变回0%，不明白原因，以为要提交进度条的真是百分比，但是发现 var actualSchedule = GetCurSchedule();这个函数并没有提交到后台，只是用于前台显示。

在”网络“选项卡中观察网页与网站的互动，发现网页定期向网站发送post，网址如下： https://api-qidatestin.yunxuetang.cn/v1

在调试器中找到相关js文件，搜索这个网址，找到两处，分别在completedStudy()  和  submitStudy()

submitStudy()函数体如下：

function submitStudy() {
    //进度
    var actualSchedule = GetCurSchedule();
    //var arr = '{"orgID":"' + orgID + '","userID":"' + userID + '","knowledgeID":"' + key + '","packageID":"' + packageID + '","masterID":"' + masterID + '","masterType":"' + masterType + '","progress":' + actualSchedule + ',"pageSize":' + pageSize + ',"studySize":' + studySize + ',"studyChapterIDs":"' + stuChpIDs + '","type":' + type + '}';
    var arr = '{"OrgID":"' + orgID + '","UserID":"' + userID + '","KnowledgeID":"' + key + '","PackageID":"' + packageID + '","MasterID":"' + masterID + '","MasterType":"' + masterType + '","PageSize":' + pageSize + ',"StudyTime":-1,"studyChapterIDs":"' + stuChpIDs + '","Type":' + type + ',"IsOffLine":false,"DeviceId":"","IsEnd":false,"ReqType":0,"IsCare":true}';
    var domainurl="";
    if(orgID=="640e03a9-e0e9-49e8-950b-9fddead1203a"||orgID=="a4a97176-c2b2-4583-a585-4a89e22feaf5"||orgID=="3a2732da-f3a5-4856-9f6c-5e36c026555e"||orgID=="45df3843-88f0-4b2b-a9ec-43223007d5c0")
    {
        domainurl="http://api-qida1.yunxuetang.cn/v1/";
    }else{
        domainurl='https://api-qidatestin.yunxuetang.cn/v1/';
    }
$.ajax({
        type: "POST",
        url: domainurl+"study",
        data: arr,
        headers: {
            "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
            "Source": 501
            // "key": "ba257d05-5eff-4be8-8db0-738bc0cabd67"
        },
        contentType: "application/json",
        dataType: "text",
        success: function (result) {
            if (result == "") {
                $('#divCheat').hide();
                //返回当前用户学习实体
                if (standardStudyHours > actualStudyHours) {
                    $("#divCompletedArea").hide();
                    $("#divStartArea").show();
                } else {
                    $("#divCompletedArea").show();
                    $("#divStartArea").hide();
                    isHere = 1;
                    if ($('#icon' + key)) {
                        $('#icon' + key).prop("class", "pic2");
                        iscurfinish = 1;
                    }
                }
                MinuteChange(actualSchedule);
            } else {
                //那么返回的是知识名称
                CheatWarming(result);
            }
        },
        error: function (xhr) {
            var msg=eval("("+xhr.responseText+")")
            CheatWarming(msg.error.message);
        }
    });
}

这个 submitStudy()正是提交学习进度的函数，原来网页上的百分百进度条是假的，通过submitstudy向服务器提交预置的固定的学习进度，比如每提交一次服务器的学习进度增加1.2%。
