Adobe Air2 NativeProcess API with Javascript
I am trying to launch a python script with the NativeProcess API from Javascript. On the Adobe AIR API Reference for HTML Developers I found a good example for that task, but it does not work. I looked up tons of other examples but still can not find the answer.
Here is the example code for the html file:
<html>
<head>
<title>Test</title>
<script type="text/javascript" src="AIRAliases.js"></script>
<script type="text/javascript">
var process;
function launchProcess()
{
if(air.NativeProcess.isSupported)
{
air.trace("NativeProcess supported.");
setupAndLaunch();
}
else
{
air.trace("NativeProcess not supported.");
}
}
function setupAndLaunch()
{
var nativeProcessStartupInfo = new air.NativeProcessStartupInfo();
var file = air.File.applicationDirectory.resolvePath("test.py");
nativeProcessStartupInfo.executable = file;
var processArgs = new air.Vector["<String>"]();
processArgs.push("foo");
nativeProcessStartupInfo.arguments = processArgs;
process = new air.NativeProcess();
process.start(nativeProcessStartupInfo);
process.addEventListener(air.ProgressEvent.STANDARD_OUTPUT_DATA, onOutputData);
process.addEventListener(air.ProgressEve开发者_运维知识库nt.STANDARD_ERROR_DATA, onErrorData);
process.addEventListener(air.NativeProcessExitEvent.EXIT, onExit);
process.addEventListener(air.IOErrorEvent.STANDARD_OUTPUT_IO_ERROR, onIOError);
process.addEventListener(air.IOErrorEvent.STANDARD_ERROR_IO_ERROR, onIOError);
}
function onOutputData()
{
air.trace("Got: ", process.standardOutput.readUTFBytes(process.standardOutput.bytesAvailable));
}
function onErrorData(event)
{
air.trace("ERROR -", process.standardError.readUTFBytes(process.standardError.bytesAvailable));
}
function onExit(event)
{
air.trace("Process exited with ", event.exitCode);
}
function onIOError(event)
{
air.trace(event.toString());
}
</script>
</head>
<body onload="launchProcess()">
</body>
</html>
And here the code for the python file (it does not work):
#! /usr/bin/env python2.5
# -*- coding: utf-8 -*-
import sys
for word in sys.argv: #echo the command line arguments
print word
print "HI FROM PYTHON"
print "Enter user name"
line = sys.stdin.readline()
sys.stdout.write("hello," + line)
Running the Air App with the command adl main.xml
shows in my terminal (I use OSX) only "NativeProcess supported."
Thanks for help.
And here the changes I did to the python file to get it working:
#! /usr/bin/env python2.5
# -*- coding: utf-8 -*-
import sys
import os
def convert(args):
path = os.path.expanduser('~') + "/Desktop/"
myFile = open(path+args, 'w')
myFile.write('Hello World\n')
myFile.close()
sys.stdout.write("Python Done")
if __name__ == "__main__":
convert(sys.argv[1])
Thanks to pyfunc...
If you run your program, then following is the output:
test.py
HI FROM PYTHON
Enter user name
Thats is this piece of python code is looking for standard input and writing to standard output. I don't think that would be possible if you do not run that from shell.
How about removing:
line = sys.stdin.readline()
sys.stdout.write("hello," + line)
and do some innocuous python expressions like
a = 1+4
and see, if that works. I have a hunch that this might be an issue.
