Help! this is driving me crazy lol
I want to print raw binary data to display an image file BUT
python3 outputs b'<binary data>' instead of<binary data>.... so the
browser can't read the image!!
f = open("/some/path/%s" % x, 'rb')
print(f.read())
print() implicitly converts its arguments to str (i.e. unicode strings)
and then writes them to sys.stdout, which is a text IO wrapper.
If you want to bypass the unicode layer, you have to use
sys.stdout.buffer instead.
That is:
sys.stdout.buffer.write(f.read())
Regards
Antoine.
@Gary : How do I reply to a http request then?
@Antoine : It not sys.stdout.buffer.write but sys.stdout.write()
instead. But it still doesn't work, now I have empty content
#!/usr/bin/python3
import cgi, os, sys
form = cgi.FieldStorage()
all = os.listdir("/some/path/with/files/")
for x in all:
if x.find( form['id'].value ) != -1:
ext = x.split(".")[-1]
print("Content-type:image/%s\n\n" % ext)
f = open("/some/path/with/files/%s" % x, 'rb')
sys.stdout.write( f.read() )
f.close()
break
