在CasperJS中,如何在使用casper.thenOpen()
时保持会话例如:
var casper = require('casper').create();
casper.start('http://chaseonline.com/', function() {
this.echo(this.getTitle());
this.evaluate(function() {
document.getElementById("userid").value = "a@b.com";
document.getElementById("password").value = "asdf";
});
this.click("#btnSubmit");
});
casper.thenOpen('http://chaseonline.com/section/1/module/2/abc.jsp', function() {
// now this page never loads because the page requires a logged in session
// but casperjs doesn't appear to automatically propagate the session
this.echo(this.getTitle());
});
casper.run();

您的示例中的会话仍处于打开状态。可能你没有登录正确。
可能如果它的工作步骤(似乎我看到的网站不是你的例子中的那个,没有登录):
var casper = require('casper').create();
var x = require('casper').selectXPath;
casper.start('http://youraddess.com/', function() {
casper.then(function() {
casper.waitForSelector(x("xpath_selector"));
});
var data = {};
casper.then(function() {
data["//input[@id='userid']"] = "a@b.com";
data["//input[@id='password']"] = "asdf";
casper.fillXPath(x("//form[]"), data, false);
});
casper.then(function() {
casper.click(x("//button[@id='btnSubmit']"));
});
casper.then(function() {
casper.waitWhileSelector(x("xpath_selector"));
});
});
casper.thenOpen('http://chaseonline.com/section/1/module/2/abc.jsp', function() {
// now this page never loads because the page requires a logged in session
// but casperjs doesn't appear to automatically propagate the session
casper.then(function() {
casper.echo(this.getTitle());
casper.capture('test.png');
});
});
casper.run();
会话直到run()始终相同。有可能打开新的,但那很难。
