Selebiun Crawler超时问题C＃

Question

The following code I am running and during execution I receive an error.

  public void GetCategoriesSelenium() {
            string javascript = System.IO.File.ReadAllText(@"GetCategory.js");
            CrawlerWebSeleniumJS.ExecuteScript("var finished;");
            CrawlerWebSeleniumJS.ExecuteScript("var all_categories;");
            CrawlerWebSeleniumJS.ExecuteScript("finished = false;");
            CrawlerWebSeleniumJS.ExecuteScript("all_categories = [];");

            CrawlerWebSelenium.Manage().Timeouts().SetScriptTimeout(TimeSpan.FromDays(1));
            CrawlerWebSelenium.Manage().Timeouts().SetPageLoadTimeout(TimeSpan.FromDays(1));
            CrawlerWebSelenium.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromDays(1));

            AddToConsole("CRAWLER: GET - Categories");

            try {
                CrawlerWebSeleniumJS.ExecuteScript(javascript);
                }
            catch {
                }

            int ready = 2;

            for (int i = 0; i < ready; i++) {
                try {
                    if (CrawlerWebSeleniumJS.ExecuteScript("return finished").ToString() == "True") {
                        i = i++ + ready++;
                        }
                    else {
                        ready++;
                        }
                    }
                catch {

                    }

    });
    //end main cat scan loop
});
finished = true;

The above code is the method that I run and the code that is under it is pure javascript that is being run through selenium.

So issue one, when the code is run selenium locks up. Which I can understand. This process takes about 4mins. After 60secs it times out with the error

The HTTP request to the remote WebDriver server for URL timed out after 60 seconds.

Which is really annoying and locks the system up. I know a really quick and easy way to get this fixed. (Thread.Sleep(300000) which is disgusting...

My thoughts are, maybe it is running a javascript query and waiting for it to finish and I am constantly pounding Selenium with more javascript requests which time out as expected.

Any other thoughts?

Answer 1

The driver's constructor should have an overload that includes a TimeSpan indicating the timeout for the HTTP client used by the .NET bindings to communicate with the remote end. Setting that to an appropriately large value should be sufficient to let the operation complete.
