如何使用RemoteWebDriver/sauce Labs/sauce Connect正确设置BrowserMobProxy/Selenium代理？

Question

我已经到处找了，但没有找到任何关于如何正确设置代理以在Sauce labs上运行脚本并提取HAR文件的好文档。我在嵌入式模式下使用BMPhttps://github.com/lightbody/browsermob-proxy#using-with-selenium，以及https://wiki.saucelabs.com/display/docs/sauce+connect+proxy。我找到了关于通过BMP手动设置和运行脚本的文档https://wiki.saucelabs.com/display/docs/sauce+connect+proxy+with+an+adatory+proxy+setup，但是他们的文档没有说明如何只通过独立模式在嵌入式模式中设置脚本。下面是我的设置：

我的PAC文件

function FindProxyForURL(url, host) {
    if (shExpMatch(host, "*.miso.saucelabs.com") ||
        shExpMatch(host, "saucelabs.com")) {
        // KGP and REST connections. Another proxy can also be specified.
        return "DIRECT";
    }

    // Test HTTP traffic, route it through the local BrowserMob proxy.
    return "PROXY localhost:9091";
}

BMP设置

我想通了。原来这是2.1.4版本中的一个bug。当我升级到2.1.5版本时，一切都正常工作。
