如何在不同的casperjs进程之间保留cookie

问题描述

这是一个关于如何保持cookie从一个casperjs页面到另一个问题。

this is a question about how to persist cookies from one casperjs page to another..

所以基本上我有一个nodejs文件，产生casperjs作为一个工人某些任务..一个是登录，一旦登录我将cookie存储在一个文件中。

so basically i got a nodejs file that spawns casperjs as a worker to do certain tasks.. one is to login, once logged in I store the cookie in a file.

当我产生下一个casper worker ..我想它使用cookie，而不必再次登录..这两种方法失败 ：

when i spawn the next casper worker.. i want it to to use the cookie rather having to login again.. both these methods failed:

第一：当我产生工作者capserjs时，我添加--cookies-file =。/ cookiefilename ie
var child = spawn（'casperjs'，['scrape.js'，' - cookies-file =。/'+ cookieFileName]）;

first: when i spawn the worker capserjs I add the --cookies-file=./cookiefilename ievar child = spawn('casperjs',['scrape.js','--cookies-file=./'+cookieFileName]);

第二在casperjs工作文件中..我使它从一个文件读取和设置cookie

second: within the casperjs worker file.. I make it read and set the cookie from a file ie

var casper = require('casper').create();
var cookieFileName = 'monsterCookie.txt';

// grab cookies from file
var fs = require('fs');
var utils = require('utils');
var cookies = fs.read(cookieFileName);

casper.page.setCookies(cookies);

casper.start('domain/page.html', function() {
    //FAIL! cookies aren't used here
    this.debugHTML();
});

casper.run();

注意：

1. 之前），同样的情况发生在同一个casperjs页面对象中（请参阅）


2. 请记住，我将cookie存储在文件中（即不存在任何json / cookie解析）..所以我的cookie文件看起来像这样

1. it was mentioned earlier that start removes cookies from the page? if so how do I prevent that?
   
2. I know that sessions persist within the same phantomjs page object (see here https://gist.github.com/abbood/5347252) and same happens within the same casperjs page object (see here https://gist.github.com/abbood/5347287)
3. keep in mind that I store cookies as is in the file (ie without any json/cookie parsing at all).. so my cookie file looks exactly like this

推荐答案

Saving cookies:

var fs = require('fs');
var cookies = JSON.stringify(phantom.cookies);
fs.write(cookieFilename, cookies, 644);

Cookie：

var fs = require('fs');
var data = fs.read(cookieFilename);
phantom.cookies = JSON.parse(data);

phantom 是PhantomJS中的全局变量。有关详情，请参阅

The phantom is global variable in PhantomJS. More information you can get in wiki
