问题描述
我尝试获取将文件推送到设备时的进度。
当我在cmd中设置ADB_TRACE = adb时可用(在此页面)
然后我想在python 2.7中使用它。
cmd =adb push file / mnt / sdcard / file
os.putenv('ADB_TRACE','adb')
os.popen(cmd)
.read()
如何获取这些详细信息?
操作系统:win7
解决方案>
os .popen
已弃用:
自2.6版后弃用:此函数已过时。使用
子进程
模块。特别是用
和子进程
模块部分检查替换旧的函数。
使用 子过程
代替:
import subprocess as sp
cmd = [adb,push file,/ mnt / sdcard / file]
mysp = sp.popen(cmd,env = {'ADB_TRACE':'adb'},stdout = sp.PIPE,stderr = sp.PIPE)
stdout,stderr = mysp.communicate()
如果mysp.returncode!= 0:
print stderr
else:
print stdout
I tried to get the progress when pushing a file to device. It works when I "set ADB_TRACE=adb" in cmd (found in this page)
Then I want to use it in python 2.7.
cmd = "adb push file /mnt/sdcard/file"
os.putenv('ADB_TRACE', 'adb')
os.popen(cmd)
print cmd.read()
It shows nothing. How can I get these details?
OS:win7
解决方案
os.popen
is deprecated:
Deprecated since version 2.6: This function is obsolete. Use the
subprocess
module. Check especially the Replacing Older Functions with thesubprocess
Module section.
Use subprocess
instead:
import subprocess as sp
cmd = ["adb","push","file","/mnt/sdcard/file"]
mysp = sp.popen(cmd, env={'ADB_TRACE':'adb'}, stdout=sp.PIPE, stderr=sp.PIPE)
stdout,stderr = mysp.communicate()
if mysp.returncode != 0:
print stderr
else:
print stdout
