直接返回图片流
这里使用管理的加载
 requireActivity().runOnUiThread(() -> Glide.with(requireActivity())
                .load(url)
                .diskCacheStrategy(DiskCacheStrategy.NONE)
                .into(root.qrImg));

dataMap = new HashMap<>();
dataMap.put("uuid", uuid);
dataMap.put("enc", enc);
String url = "http://passport2.chaoxing.com/getauthstatus";
Jsoup.connect(url).cookies(cookies).data(dataMap).method(Connection.Method.POST).execute();
cookies是第一次请求地址的返回cookie

String getClassUrl = "http://mooc1-2.chaoxing.com/visit/courses";

    if (classDocument.title().contains("用户登录")) {
        Toast.makeText(requireActivity(), "cookies失效,请重新登录", Toast.LENGTH_SHORT).show();
        return;
    }
} catch (IOException e) {
    e.printStackTrace();
}
Elements classElements = classDocument.select(".ulDiv > ul > li[style]");
for (Element classElement : classElements) {
    ClassBean classBean = new ClassBean();

    //任务地址
    String url = "https://mobilelearn.chaoxing.com/widget/pcpick/stu/index?courseId=" + courseId + "&jclassId=" + classId;
    classBean.setCourseId(courseId);

}

任务列表：url = "https://mobilelearn.chaoxing.com/widget/pcpick/stu/index?courseId=206811209&jclassId=13721305"

Connection.Response response = Jsoup.connect(url).cookies(mViewModel.getCookies()).method(Connection.Method.GET).execute();
Document document = response.parse();
elements = document.select("#startList div .Mct");
elements是签到列表元素
