我回答了我自己的问题，请参见下面的编辑.

I answered my own question, see edit below.

原始: 我在我的Web服务器上安装了phantomjs和casperjs，它们都可以正常运行.我计划创建的脚本依赖于我网站上的用户输入，然后将其传递给casperjs脚本. 经过一番摆弄之后，我注意到我被困在用户输入的最基本任务上.如何将变量从php传递到casperjs?

ORIGINAL: I have phantomjs and casperjs installed on my web server and they both run fine. The script I am planning on creating relise on a user input from my website, which is then passed on to the casperjs script. After fiddling around a bit, I noticed that I am stuck on the very basic task of the user input. How would pass the variable from php to casperjs?

请注意，以下只是测试脚本.

Please note, the following are just test scripts.

我的php脚本

$user_input = $_POST['user_input']; putenv("PHANTOMJS_EXECUTABLE=/usr/local/bin/phantomjs"); exec('/usr/local/bin/casperjs hello.js 2>&1',$output); print_r($output);

hello.js

var user_input = "example/"; var casper = require('casper').create({ verbose: true, logLevel: 'error', pageSettings: { loadImages: false, loadPlugins: false } }); casper.start(user_input, function() { this.echo(this.getTitle()); }); casper.run();

那么我该如何将$ user_input传递给hello.js.我的目标是用户可以输入一个网址，然后将该网址抓取.

So how would I pass the $user_input to the hello.js. My goal is that the user can input a url which is then being scraped.

推荐答案

我自己找到了答案.

似乎phantomjs和casperjs支持命令行参数 phantomjs/api /system/property/args.html

It seems phantomjs and casperjs support command line arguments phantomjs/api/system/property/args.html

我的脚本现在看起来像这样.

My script now looks like this.

test.php

$user_input = $_POST['user_input']; putenv("PHANTOMJS_EXECUTABLE=/usr/local/bin/phantomjs"); exec('/usr/local/bin/casperjs hello.js $user_input 2>&1',$output); print_r($output);

hello.js

var system = require('system'); var args = system.args; var address = args[4]; //In my case 4 was the argument for $user_input, yours might be different, depending on your server setup. var casper = require('casper').create({ verbose: true, logLevel: 'error', pageSettings: { loadImages: false, loadPlugins: false } }); casper.start(address, function() { this.echo(this.getTitle()); }); casper.run();
