的Adobe AIR2的NativeProcess API的JavaScript [英] Adobe Air2 NativeProcess API with Javascript
问题描述
我想推出一个python脚本在Javascript中的NativeProcess API。 在的Adobe AIR API参考针对HTML开发我发现了一个很好的例子，该任务，但它不工作。我抬头吨的其他例子，但仍无法找到答案。
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.
下面是例子code HTML文件：
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.ProgressEvent.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>
和这里的code为Python文件（它不工作）：
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)
用命令运行AIR应用程序ADL的main.xml 显示我的终端（我用OSX）只的NativeProcess支持。
Running the Air App with the command adl main.xml shows in my terminal (I use OSX) only "NativeProcess supported."
感谢您的帮助。
在这里，我没有给Python文件的修改得到它的工作：
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])
由于pyfunc ...
Thanks to pyfunc...
推荐答案
如果您运行的程序，然后下面是输出：
If you run your program, then following is the output:
test.py
HI FROM PYTHON
Enter user name
那是这片蟒蛇code正在寻找标准输入和写入标准输出。 我不认为这是可能的，如果你不运行，从外壳。
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.
如何删除：
line = sys.stdin.readline()
sys.stdout.write("hello," + line)
和做一些无关痛痒的蟒蛇EX pressions像
and do some innocuous python expressions like
a = 1+4
和看到的，是否可行。我有一种预感，这可能是一个问题。
and see, if that works. I have a hunch that this might be an issue.
