网站开发款计入什么科目深圳市seo上词多少钱

实现的细节和引用的文件和以前博客记录的基本一致

https://shaka.blog.csdn.net/article/details/106927633

差别在于,这次是通过跳板机登陆获取的主机信息,只记录差异的部份

1.需要在跳板机相应的路径放置PYTHON的脚本resc.py

resc.py这个脚本中有引用的文件(pm.sh,diskpnum.sh)和以前的记录一样,不再重复列出

这个脚本接受一个参数,IP地址,django一端的服务器将通过SSH连接,并将参数传递给脚本执行

脚本将返回包含CPU,内存,磁盘信息的字典,因为不同主机的磁盘分区名称和数量的不一致性,带有磁盘信息的这个KEY的值,将是一个LIST

2.django一端的实现如下:

views.py对应的方法

用户点击不同的按钮选择是打印到WEB页面,还是打印到WEB页面+下载巡检报告的EXCEL表格

request.POST.has_key('chkaproc')或request.POST.has_key('chkonlylists')

def chkosinfos(request):if request.method=="POST":sqlstr = request.POST.get("sqlstr")filenames=""if request.POST.has_key('chkaproc'):try:import f5.sysinfos#filenames,relists=f5.sysinfos.receivewebsqlstr(sqlstr)relists=f5.sysinfos.remoterelists(sqlstr)filenames=f5.sysinfos.remotereexcel(relists)except Exception:return render(request,"exportsysinfos.html",{"login_err":"SYSINFOSFAILSTEP1"})return render(request,"exportsysinfos.html",{"login_err":"downloadlink:http://web服务器IP地址(存放文件用,程序将文件生成到指定的web虚拟目录):9999/"+filenames,"templist":relists})if request.POST.has_key('chkonlylists'):try:import f5.sysinfosrelists=f5.sysinfos.remoterelists(sqlstr)except Exception:return render(request,"exportsysinfos.html",{"login_err":"SYSINFOSFAILSTEP1"})return render(request,"exportsysinfos.html",{"login_err":"OKAY"+filenames,"templist":relists})else:return render(request,"exportsysinfos.html",{"login_err":"no set"})

views.py引用的两个方法

remoterelists返回多个服务器巡检信息的list
remotereexcel将信息写入excel

3.HTML页面将用户需要巡检的IP列表粘贴到输入框,一行一个IP

html的写法,不怎么会写,只是先写个实现
