PHP time（）和.htaccess％{TIME}之差(PHP time() and .htaccess %{TIME} difference)

 我找到了问题的解决方案。 使用PIL包时，在安装过程中无法正确编译。 之后我有一个依赖问题。 我用以下方式修复它： 
 
import PIL.EpsImagePlugin
PIL.EpsImagePlugin.Ghostscript = mioGhostscript
 
 然后我在命令中看到了这个： 
 
"- >/dev/null 2>/dev/null"
 
 代码是shell的代码，它在我的系统上不起作用，因为python试图读取一个字面名为- >/dev/null 2>/dev/null ，它不存在。 
 
 我换了 
 
"- >/dev/null 2>/dev/null"
 
 同 
 
"-" 
 
 现在程序从stdin读取。 
 
 最终的代码是： 
 
def mioGhostscript(tile, size, fp):
    """Render an image using Ghostscript (Unix only)"""

    # Unpack decoder tile
    decoder, tile, offset, data = tile[0]
    length, bbox = data

    import tempfile, os

    file = tempfile.mktemp()

    # Build ghostscript command
    command = ["gs",
        "-q",                    # quite mode
        "-g%dx%d" % size,        # set output geometry (pixels)
        "-dNOPAUSE -dSAFER",     # don't pause between pages, safe mode
        "-sDEVICE=ppmraw",       # ppm driver
        "-sOutputFile=%s" % file,# output file
        "-"
    ]

    #command = shlex.split(string.join(command))
    # push data through ghostscript

    try:
        #gs = os.popen(command, "w")

        args = command#['gs','-dSAFER','-dNOPAUSE','-dBATCH','-sDEVICE=jpeg','-sOutputFile=/home/user/output2.jpg /home/user/downloads/test.pdf']
        gs = subprocess.Popen( args, stdout = PIPE, stderr = STDOUT, stdin=PIPE )
        # adjust for image origin
        if bbox[0] != 0 or bbox[1] != 0:
            #gs.write("%d %d translate\n" % (-bbox[0], -bbox[1]))
            gs.stdin.write("%d %d translate\n" % (-bbox[0], -bbox[1]))
        fp.seek(offset)
        while length > 0:
            s = fp.read(8192)
            if not s:
                break
            length = length - len(s)
            gs.stdin.write(s)
        gs.communicate()[0]
        status = gs.stdin.close()
        #status = gs.close()
        #if status:
        #   raise IOError("gs failed (status %d)" % status)
        im = Image.core.open_ppm(file)
    finally:
        try: os.unlink(file)
        except: pass

    return im

 我希望这些帖子可以帮助别人。 

I found the solution at the problem. It was with the PIL package, something didn't compile right during the installation. After that i had a dependencies problem. I fixed it in the following way:
 
import PIL.EpsImagePlugin
PIL.EpsImagePlugin.Ghostscript = mioGhostscript
 
Then I saw this in the command:
 
"- >/dev/null 2>/dev/null"
 
the code is a shell's code and it didn't work on my system because python tried to read a file literally named - >/dev/null 2>/dev/null and it doesn't exist.
 
I replaced 
 
"- >/dev/null 2>/dev/null"
 
with 
 
"-" 
 
and the program now read from the stdin.
 
The final code is:
 
def mioGhostscript(tile, size, fp):
    """Render an image using Ghostscript (Unix only)"""

    # Unpack decoder tile
    decoder, tile, offset, data = tile[0]
    length, bbox = data

    import tempfile, os

    file = tempfile.mktemp()

    # Build ghostscript command
    command = ["gs",
        "-q",                    # quite mode
        "-g%dx%d" % size,        # set output geometry (pixels)
        "-dNOPAUSE -dSAFER",     # don't pause between pages, safe mode
        "-sDEVICE=ppmraw",       # ppm driver
        "-sOutputFile=%s" % file,# output file
        "-"
    ]

    #command = shlex.split(string.join(command))
    # push data through ghostscript

    try:
        #gs = os.popen(command, "w")

        args = command#['gs','-dSAFER','-dNOPAUSE','-dBATCH','-sDEVICE=jpeg','-sOutputFile=/home/user/output2.jpg /home/user/downloads/test.pdf']
        gs = subprocess.Popen( args, stdout = PIPE, stderr = STDOUT, stdin=PIPE )
        # adjust for image origin
        if bbox[0] != 0 or bbox[1] != 0:
            #gs.write("%d %d translate\n" % (-bbox[0], -bbox[1]))
            gs.stdin.write("%d %d translate\n" % (-bbox[0], -bbox[1]))
        fp.seek(offset)
        while length > 0:
            s = fp.read(8192)
            if not s:
                break
            length = length - len(s)
            gs.stdin.write(s)
        gs.communicate()[0]
        status = gs.stdin.close()
        #status = gs.close()
        #if status:
        #   raise IOError("gs failed (status %d)" % status)
        im = Image.core.open_ppm(file)
    finally:
        try: os.unlink(file)
        except: pass

    return im
