问题
I am writing a bash script in where I am trying to submit a post variable, however wget is treating it as multiple URLS I believe because it is not URLENCODED... here is my basic thought
MESSAGE='I am trying to post this information'
wget -O test.txt http://xxxxxxxxx.com/alert.php --post-data 'key=xxxx&message='$MESSAGE''
I am getting errors and the alert.php is not getting the post variable plus it pretty mush is saying
can't resolve I can't resolve am can't resolve trying .. and so on.
My example above is a simple kinda sudo example but I believe if I can url encode it, it would pass, I even tried php like:
MESSAGE='I am trying to post this information'
MESSAGE=$(php -r 'echo urlencode("'$MESSAGE'");')
but php errors out.. any ideas? How can i pass the variable in $MESSAGE without php executing it?
回答1:
You want $MESSAGE to be in double-quotes, so the shell won't split it into separate words:
ENCODEDMESSAGE=$(php -r "echo urlencode(\"$MESSAGE\");")

On CentOS, no extra package needed:
python -c "import urllib;print urllib.quote(raw_input())" <<< "$message"

Extending Rockallite's very helpful answer for Python 3 and multiline input from a file (this time on Ubuntu, but that shouldn't matter):
cat any.txt | python3 -c "import urllib.parse, sys; print(urllib.parse.quote(sys.stdin.read()))"
This will result in all lines from the file concatenated into a single URL, the newlines being replaced by %0A.

Pure Bash way:
URL='rom%C3%A2ntico'
echo -e "${URL//%/\\x}"
echoes:
romântico
'C3 A2' is 'â' in utf8 hex
