我正在使用NodeJs和ZombieJS在虚拟浏览器环境中获取url请求。僵尸错误 - 获取http请求时出错
我使用下面的代码:
var zombie = require('zombie'),
jsdom = require('jsdom'),
my_sandbox = require('sandbox'),
url = require('url'),
http = require('http'),
request = require('request'),
httpProxy = require('./lib/node-http-proxy'),
des = '',
util = require('util'),
colors = require('colors'),
is_host = true;
var s = new my_sandbox();
var browser = new zombie.Browser;
httpProxy.createServer(9000, 'localhost').listen(8000);
function zombieFetching(page) {
browser.visit(page, { debug: false },
function(err, browser, status) {
if(err) {
console.log('There is an error. Fix it');
throw(err.message);
} else {
console.log('Browser visit successful') ;
}
});
}
var server = http.createServer(function (req, res) {
var pathname = '';
if(is_host) {
dest = req.url.substr(0, req.url.length);
pathname = dest;
is_host = false;
} else {
pathname = req.url.substr(0, req.url.length);
if(pathname.charAt(0) == "/") {
console.log('new request');
console.log(pathname);
pathname = dest + pathname;
}
}
request.get({uri: pathname}, function (err, response, html) {
console.log('The pathname is:::::::::: ' + pathname);
zombieFetching(pathname);
res.end(html);
});
});
server.listen(9000);
我看到下面的错误,当我尝试获取的URL: “www.yahoo.com”
home/seed/Desktop/Cloud project/node_modules/zombie/node_modules/html5/lib/html5/tokenizer.js:62
throw(e);

此外,日志报表如下:
The pathname is:::::::::: http://www.yahoo.com/
The pathname is:::::::::: http://l1.yimg.com/a/i/ww/news/2011/05/06/zuckhouse-sm.jpg

The pathname is:::::::::: http://www.yahoo.com/jserror?ad=1&target=cms&data=FPAD
从我所了解的情况来看,前四个获得请求是成功的。 不过,我不知道为什么僵尸被提取的无效请求:
"http://www.yahoo.com/jserror?ad=1&target=cms&data=FPAD"
而且,是什么原因造成的标记名称错误的无效字符?

如果我请求url:http://unixhelp.ed.ac.uk/CGI/man-cgi?grep,错误日志是:throw(err.message); ^ 无法加载资源http://unixhelp.ed.ac.uk/favicon.ico,得到404.此网址无效,我不确定为何要提取此请求。我不确定这是否是node/zombie中的错误,或者我的代码中是否有错误。 – sony 2011-05-08 23:03:54
