PhantomJS使用基本auth返回null进行评估 [英] PhantomJS evaluate with basic auth returning null

问题描述

我正在尝试在基本始终为auth的页面上使用PhantomJS，例如，此页

I am trying to use PhantomJS on a page with basic always auth, for example, this page

http://alexturpin.net/auth （ test：rosebud ）

使用以下代码

var webpage = require('webpage');

page = webpage.create();
page.settings = {
    userName: "test",
    password: "rosebud"
};

page.open("http://alexturpin.net/auth/", function(status) {
    console.log(status);
    var retval = page.evaluate(function() {
        return "test";
    });
    console.log(retval);
});

我得到这个输出

$ phantomjs test.js
success
null

无论我尝试什么，评估将继续返回 null ，即使该页面似乎已被打开，因为状态包含成功。

Whatever I try, evaluate will keep returning null, even though the page seems to have been opened fine because status contains "success".

如果我决定开启没有基本身份验证的页面，如 http://alexturpin.net/noauth ，我仍然得到相同的结果。只有当我在打开页面之前完全删除身份验证设置时才能正常工作。

If I decide to open a page with no basic auth, like http://alexturpin.net/noauth, I still get the same results. Only when I finally remove the authentication settings altogether before opening the page does it work.

使用身份验证设置似乎与评估冲突。这是PhantomJS中的一个错误，还是我错过了什么？

The use of authentication settings seem to be conflicting with the evaluate. Is this a bug in PhantomJS, or did I miss something?

推荐答案

使用该语法，您将清除设置对象，替换只有 userName 和密码。使用该代码进行设置：

With that syntax you are wiping out the settings object, replacing it with only userName and password. Use that code to set them:

page.settings.userName = "test";
page.settings.password = "rosebud";

可能PhantomJS应该更好地处理，即不依赖设置默认对象。

Probably PhantomJS should handle that better, i.e. not rely on the settings object for defaults.
