我在玩 zombie 脚本:
var Browser = require('zombie');
var assert = require('assert');
var browser = Browser.create();
browser.debug = true;
browser.maxRedirects = 50;
browser.userAgent = 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.71 Safari/537.36';
browser.visit('https://redacted.com').
then(function () {
console.log(browser.evaluate("document.URL"));
console.log(browser.evaluate("document.title"));
return browser.
fill('uid','aUser').
fill('password', 'aPassword').
pressButton('Sign In');
}).then(function() {
console.log("Signed in?");
console.log(browser.evaluate('document.URL'));
console.log(browser.evaluate("document.title"));
});
我看到了一个引用错误:
zombie_experiment$ node zombie1.js

这个引用错误是真实的，还是我的脚本不是 zombie.js 的标准用例？
最佳答案
我无法让 Raphael 使用 zombiejs。和jsdom处理canvas的方式有关。 Raphael 在检测绘图引擎类型时静默失败。
对我来说，唯一的解决方案是避开我的应用程序中使用 Raphael 在 Canvas 上绘图的部分。 :(
关于testing - 在 zombie.js 中缺少 Raphael 依赖项？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/26409662/
