Java Python子进程不传输参数
我希望使用自动化从大型OSM文件提取数据的过程,但在运行此代码段以从OSM数据自动创建磁贴时遇到问题:Java Python子进程不传输参数,java,python,subprocess,osmosis,Java,Python,Subprocess,Osmosis,我希望使用自动化从大型OSM文件提取数据的过程,但在运行此代码段以从OSM数据自动创建磁贴时遇到问题: import sys import subprocess def create_tile_pbf(pbf_file, tile_lng, tile_lat): """Runs the osmosis tile creator""" app_path = "osmosis/bin/" app = "osmosis.bat" proc = subprocess.P

while proc.returncode is None:
proc.communicate()
proc.poll()
print(">> Terminated\n")
if __name__ == "__main__":
print("Args were: " + str(sys.argv) + "\n")
create_tile_pbf("./somefile.osm.pbf", 7, 46)
我尝试使用和不使用shell=True
,我尝试将所有参数合并到一个字符串中。但我在执行时总是会遇到这样的错误:

但是,当使用Powershell或命令提示符运行命令时,它就像一个符咒
.\osmosis.bat --read-pbf .\somefile.osm.pbf --bounding-box top=47 left=7 bottom=46 right=8 --write-pbf someotherfile.osm.pbf
我正在使用Anaconda 4.3.30运行Windows 10 1703 64位。脚本和命令提示符交互之间的区别是
渗透/bin/osition.bat
与\osition.bat
。由于对Popen()
的调用已经包含cwd
选项,因此无需再次指定目录。这意味着您的电话应该是:
proc = subprocess.Popen([
app, # <== No app_path here
"--read-pbf", pbf_file,
"--bounding-box",
"top=%d" % (tile_lat+1),
"left=%d" % (tile_lng),
"bottom=%d" % (tile_lat),
"right=%d" % (tile_lng+1),
"--write-pbf", "someotherfile.osm.pbf"
], cwd=app_path, shell=True) # <== because of this cwd
proc=subprocess.Popen([
应用程序,#使用echo%1%2创建你自己的渗透作用.bat…以查看它的调用方式。是的,这已修复了它。我已经尝试过了,但我不得不将我的应用程序更改为\osition.bat
,而不仅仅是osition.bat
。
