Selenium 使用 Python:为 firefox 输入/提供 http 代理密码 [英] Selenium using Python: enter/provide http proxy password for firefox

问题描述

我想将 selenium 与受密码保护的代理一起使用.代理不是固定的，而是一个变量.所以这必须在代码中完成(只是在这台特定的机器上设置 firefox 来使用代理是不太理想的).到目前为止，我有以下代码:

I want to use selenium with a proxy which is password protected. The proxy is not fixed, but a variable. So this has to be done in the code (just setting up firefox on this particular machine to work with the proxy is less-than-ideal). So far I have the following code:

fp = webdriver.FirefoxProfile()
# Direct = 0, Manual = 1, PAC = 2, AUTODETECT = 4, SYSTEM = 5
fp.set_preference("network.proxy.type", 1)

fp.set_preference("network.proxy.http", PROXY_HOST)
fp.set_preference("network.proxy.http_port", PROXY_PORT)

driver = webdriver.Firefox(firefox_profile=fp)
driver.get("http://whatismyip.com")

此时，弹出请求代理用户/通行证的对话框.

At this point, the dialog pops up requesting the proxy user/pass.

是否有一种简单的方法:

Is there an easy way to either:

1. 在对话框中输入用户/密码.
2. 在较早的阶段提供用户/通行证.

推荐答案

Selenium 本身无法做到这一点.我认为有帮助的唯一方法是此处.简而言之，您需要动态添加一个浏览器扩展来进行身份验证.它比看起来要简单得多.

Selenium can't do that by itself. The only way I found helpful is described here. To be short, you need to add a browser extension on fly that does the authentication. It's much simpler than may seem to be.

以下是 Chrome 的工作原理(就我而言):

Here is how it works for Chrome (in my case):

1. 创建一个包含两个文件的 zip 文件 proxy.zip:

background.js

var config = {
    mode: "fixed_servers",
    rules: {
      singleProxy: {
        scheme: "http",
        host: "YOU_PROXY_ADDRESS",
        port: parseInt(YOUR_PROXY_PORT)
      },
      bypassList: ["foobar.com"]
    }
  };

chrome.proxy.settings.set({value: config, scope: "regular"}, function() {});

function callbackFn(details) {
    return {
        authCredentials: {
            username: "YOUR_PROXY_USERNAME",
            password: "YOUR_PROXY_PASSWORD"
        }
    };
}

chrome.webRequest.onAuthRequired.addListener(
        callbackFn,
        {urls: ["<all_urls>"]},
        ['blocking']
);

不要忘记将 YOUR_PROXY_* 替换为您的设置.

Don't forget to replace YOUR_PROXY_* to your settings.

ma​​nifest.json

{
    "version": "1.0.0",
    "manifest_version": 2,
    "name": "Chrome Proxy",
    "permissions": [
        "proxy",
        "tabs",
        "unlimitedStorage",
        "storage",
        "<all_urls>",
        "webRequest",
        "webRequestBlocking"
    ],
    "background": {
        "scripts": ["background.js"]
    },
    "minimum_chrome_version":"22.0.0"
}

1. 添加创建的proxy.zip作为扩展

1. Add the created proxy.zip as an extension

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_extension("proxy.zip")

driver = webdriver.Chrome(executable_path='chromedriver.exe', chrome_options=chrome_options)
driver.get("http://google.com")
driver.close()

就是这样.对我来说，这就像一个魅力.如果您需要动态创建 proxy.zip 或需要 PHP 示例，请转到 原始帖子

That's it. For me that worked like a charm. If you need to create proxy.zip dynamically or need PHP example then go to the original post
