【已解决】Python脚本用&去后台运行时__file__不起效果

折腾：

【未解决】Win10中上线对接iOS自动抓包工具

期间，但是从输出的路径看：

crifanli@crifanlideMac  ~  cd /Users/crifanli/dev/DevRoot/appcrawler

AppCralwerFolder

等都是空

所以不对。去看看代码：

CurFilePath = __file__
PlatformIntegrationFolder = os.path.dirname(CurFilePath)
AppCralwerFolder = os.path.dirname(PlatformIntegrationFolder)
# /Users/xxx/dev/xxx/crawler/appAutoCrawler/AppCrawler
# AppCrawler project task root folder, used for save task file
# TaskFoderRoot = "/Users/xxx/dev/xxx/crawler/appAutoCrawler/AppCrawler/task"
TaskFoderRoot = os.path.join(AppCralwerFolder, "task")
WebDriverAgentRoot = os.path.join(AppCralwerFolder, "iOSAutomation", "refer", "WebDriverAgent")
# /Users/xxx/dev/xxx/crawler/appAutoCrawler/AppCrawler/iOSAutomation/refer/WebDriverAgent

    logging.info("CurFilePath=%s", CurFilePath)
    logging.info("PlatformIntegrationFolder=%s", PlatformIntegrationFolder)
    logging.info("AppCralwerFolder=%s", AppCralwerFolder)
    logging.info("TaskFoderRoot=%s", TaskFoderRoot)
    logging.info("WebDriverAgentRoot=%s", WebDriverAgentRoot)
    logging.info("OutputRootFolder=%s", OutputRootFolder)

感觉是：

__file__ 没起效果啊

那就暂时去：

换直接用：

cd platformIntegration
python autoProcessTask.py &

试试：

结果问题依旧：

(venv)  ✘ crifanli@crifanlideMac  ~/dev/DevRoot/appcrawler   master ●  cd platformIntegration
(venv)  crifanli@crifanlideMac  ~/dev/DevRoot/appcrawler/platformIntegration   master ●  python autoProcessTask.py&

(venv)  ⚙ crifanli@crifanlideMac  ~/dev/DevRoot/appcrawler/platformIntegration   master ●  20200723 03:45:33 autoProcessTask.py:1585 INFO    CurFilePath=autoProcessTask.py

20200723 03:45:33 autoProcessTask.py:1590 INFO    OutputRootFolder=output

感觉是__file__ 不起效果？

python background __file__ not work

python – os.path.dirname(__file__) returns empty – Stack Overflow

那去试试

os.path.dirname(os.path.abspath(__file__))

不过感觉此处还是__file__本身是空的？

Unable to obtain actual directory for __file__ Python – Stack Overflow

Get the path of running file (.py) in Python: __file__ | note.nkmk.me

所以还是先去用print打印看看是否有值再说

CurFilePath = __file__
print("CurFilePath=%s" % CurFilePath)

结果：

 CurFilePath=autoProcessTask.py
PlatformIntegrationFolder=
20200723 03:53:46 autoProcessTask.py:1587 INFO    CurFilePath=autoProcessTask.py
20200723 03:53:46 autoProcessTask.py:1588 INFO    PlatformIntegrationFolder=

很明显，此处输出的是：

当前相对路径的文件名

再去回到父级目录试试

(venv)  ✘ crifanli@crifanlideMac  ~/dev/DevRoot/appcrawler/platformIntegration   master ●  cd ..
(venv)  crifanli@crifanlideMac  ~/dev/DevRoot/appcrawler   master ●  python platformIntegration/autoProcessTask.py&
[1] 14491
(venv)  ⚙ crifanli@crifanlideMac  ~/dev/DevRoot/appcrawler   master ●  CurFilePath=platformIntegration/autoProcessTask.py
PlatformIntegrationFolder=platformIntegration
20200723 03:55:23 autoProcessTask.py:1587 INFO    CurFilePath=platformIntegration/autoProcessTask.py
20200723 03:55:23 autoProcessTask.py:1588 INFO    PlatformIntegrationFolder=platformIntegration
20200723 03:55:23 autoProcessTask.py:1589 INFO    AppCralwerFolder=

的确就是：__file__只输出了相对（当前目录的）路径的当前文件名

所以看来是应该去改为：

os.path.abspath(__file__)

代码：

# CurFilePath = __file__
CurFilePath = os.path.abspath(__file__)
print("CurFilePath=%s" % CurFilePath)

结果就可以得到完整路径了：

(venv)  crifanli@crifanlideMac  ~/dev/DevRoot/appcrawler   master ●  python platformIntegration/autoProcessTask.py &
[1] 14690
(venv)  ⚙ crifanli@crifanlideMac  ~/dev/DevRoot/appcrawler   master ●  CurFilePath=/Users/crifanli/dev/DevRoot/appcrawler/platformIntegration/autoProcessTask.py

20200723 03:58:19 autoProcessTask.py:1593 INFO    OutputRootFolder=/Users/crifanli/dev/DevRoot/appcrawler/platformIntegration/output

【总结】

此处，之前调试时，__file__得到的路径没问题。

去实际作为服务后台运行时：

python platformIntegration/autoProcessTask.py &

结果：

CurFilePath = __file__

__file__ 只输出了相对路径的文件名

导致后续路径不对。

所以为了获取完整的路径，绝对路径，需要改为：

CurFilePath = os.path.abspath(__file__)

才可以。
