Usage

####Example I:

PhantomJSFileExecutor ex = new PhantomJSFileExecutor(PhantomJSReference.create().build(), new ExecutionTimeout(1, TimeUnit.SECONDS));
String output = executor.execute(new File("~/scrapper.js")).get();
System.out.println(output);  // This prints "TEST1"

####Example II:

PhantomJSFileExecutor ex = new new PhantomJSFileExecutor(PhantomJSReference.create().build(), new ExecutionTimeout(1, TimeUnit.SECONDS));
String output = executor.execute("console.log('TEST1');phantom.exit();").get()
System.out.println(output);  // This prints "TEST1"

####Example III:

PhantomJSConsoleExecutor ex = new PhantomJSConsoleExecutor(PhantomJSReference.create().build());
ex.start();
ex.execute("var system = require('system');");
	System.out.println(ex.execute("system.stdout.writeLine('TEST1');", "true")); // This prints "TEST1"
	System.out.println( ex.execute("system.stdout.writeLine('TEST2');", "true")); // This prints "TEST2"
	ex.destroy();

embedphantomjs's Issues

How to put your executor into phantomjs.binary.path?

Hi,

Can u provide sample where I can setup phantomjs.binary.path to point to your embedded driver?

Stuck when phantomjs write to stderr

Hi,

This lib helps me a lot, thanks.

final CompletableFuture<String> action = CompletableFuture.supplyAsync(() -> {
	try {
		LOGGER.info("Command to execute: " + cmd);
		final String output = IOUtils.toString(process.getInputStream(), Charset.defaultCharset());
		process.waitFor();
		LOGGER.debug("Command " + cmd + " output:" + output);
		return output;
	} catch (Exception e) {
		throw new RuntimeException(e);
	}
}, processExecutorService);

Here, Java process only read from phantomjs stdout.
When phantomjs write to stderr and the stderr buffer pipe( maybe 4KB? ) between Java and phantomjs is full, phantomjs will blocking at writing to stderr and stuck.

Now, I use a bash script to replace phantomjs bin and call real phantomjs bin in the script and 2>/dev/null and it works.

Not an issue - question only

Is embedphantomjs suitable for running selenium tests?

Command page.render not working
