我一直试图在这个答案后找到上一个网址：
Django request to find previous referrer
所以，在我的.py中我做了：
print request.META
print request.META.HTTP_REFERER
print request.META['HTTP_REFERER']
request.META 返回：
{'RUN_MAIN': 'true', 'HTTP_REFERER': 'http://127.0.0.1:8000/info/contact/', 'XDG_GREETER_DATA_DIR': '/var/lib/lightdm-data/user', 'QT4_IM_MODULE': 'xim',....
所以，我可以看到HTTP_REFERER存在，但是当我尝试访问它时，我得到错误：
<type 'exceptions.AttributeError'>
'dict' object has no attribute 'HTTP_REFERER'
我如何访问它？

List<JobExecutionContext> currentJobs = s_scheduler.getCurrentlyExecutingJobs();
for (JobExecutionContext jobCtx : currentJobs) {
JobKey jobKey = jobCtx.getJobDetail().getKey();
JobDetail jobDetail = s_scheduler.getJobDetail(jobKey);
List<? extends Trigger> triggers = s_scheduler.getTriggersOfJob(jobKey);
Date nextFireTime = null;
if (triggers.size() > 0)
{
nextFireTime = triggers.get(0).getNextFireTime();
}
logger.debug("Name= "+ jobKey.getName() + " Group=" + jobKey.getGroup() + " NextFireTime=" + nextFireTime);
}
} catch (Exception e) {
logger.debug("debugPrintJobs:" + e.getMessage());
}
是一本字典。
request.META因为您尝试访问print request.META.HTTP_REFERER
作为属性，但您应该将其作为项目
HTTP_REFERER如果您不确定print request.META['HTTP_REFERER']
中是否包含此项目，可以使用request.META方法作为其他回复者建议
get如果print request.META.get('HTTP_REFERER', '')
位于request.META['HTTP_REFERER']，则会输出HTTP_REFERER，否则会打印request.META作为''的第二个参数。 get将是默认值。

我建议：
request.META.get('HTTP_REFERER')
