问题描述

我正在尝试使用 Azure Function C# 代码中的 Selenium WebDriver.dll 并在实例化 WebDriver 时遇到以下问题.

i am trying to use Selenium WebDriver.dll from Azure Function C# code and having following issue when instantiating WebDriver.

错误:

2017-10-16T20:02:25.169 执行函数时出现异常:Functions.fnTestSelenium.Microsoft.Azure.WebJobs.Script:出现一个或多个错误.mscorlib:路径不是合法形式.2017-10-16T20:02:25.278 功能完成(失败，Id=2fcb928f-ee39-4cfe-99f2-4be2d57e91b2，持续时间=843ms)

代码

#r "D:homesitewwwrootfnTestSeleniuminWebDriver.dll"使用 System.Net；

#r "D:homesitewwwrootfnTestSeleniuminWebDriver.dll" using System.Net;

using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;

public static async Task<HttpResponseMessage> Run(HttpRequestMessage req, TraceWriter log)
{
    log.Info("C# HTTP trigger function processed a request.");

    IWebDriver driver=new FirefoxDriver();
    // parse query parameter
    string name = req.GetQueryNameValuePairs()
        .FirstOrDefault(q => string.Compare(q.Key, "name", true) == 0)
        .Value;

    // Get request body
    dynamic data = await req.Content.ReadAsAsync<object>();

    // Set name to query string or body data
    name = name ?? data?.name;

    return name == null
        ? req.CreateResponse(HttpStatusCode.BadRequest, "Please pass a name on the query string or in the request body")
        : req.CreateResponse(HttpStatusCode.OK, "Hello " + name);
}

推荐答案

我认为在 Azure Functions 上运行 Selenium 不会有太大的成功.

I don't think you'll have much success running Selenium on Azure Functions.

Azure Functions，如 WebApp 和移动应用，在应用服务中运行.应用服务在称为沙盒的安全环境中运行，该环境具有一定的限制.其中，就是使用GDI+.

Azure Functions, like WebApps and Mobile Apps, run in an App Service. The App Service runs in a secure environment called a sandbox which imposes certain limitation. Amongst them, is the use of GDI+.

您可以查看限制列表以及不支持的框架列表 https://github.com/projectkudu/kudu/wiki/Azure-Web-App-sandbox#unsupported-frameworks

You can see the list of limitation, along with the list of unsupported frameworks https://github.com/projectkudu/kudu/wiki/Azure-Web-App-sandbox#unsupported-frameworks

如果你往底部检查，你会在不支持的列表中看到 Selenimum:

If you check towards the bottom, you will see Selenimum in the list of unsupported:

其他不支持的场景:

PhantomJS/Selenium:尝试连接到本地地址，也使用GDI+.

PhantomJS/Selenium: tries to connect to local address, and also uses GDI+.
