# Tarayıcı Ayarları

### Tarayıcı Ayarları

**Komut Satırı Penceresinin Gizlenmesi**

```csharp
var firefoxService = FirefoxDriverService.CreateDefaultService();
firefoxService.HideCommandPromptWindow = true;

var chromeService = ChromeDriverService.CreateDefaultService();
chromeService.HideCommandPromptWindow = true;
```

**Tarayıcı Penceresinin Gizlenmesi**

```csharp
var chromeOptions = new ChromeOptions();
chromeOptions.AddArguments(BrowserOptionNames.ChromeHeadless);
..
new ChromeDriver(chromeService, chromeOptions);

var firefoxOptions = new FirefoxOptions();
firefoxOptions.AddArguments(BrowserOptionNames.FirefoxHeadless);
..
new FirefoxDriver(firefoxService, firefoxOptions);
```

**İndirilen Dosya Konumu Belirleme**

```csharp
var firefoxOptions = new FirefoxOptions();
firefoxOptions.SetPreference(“browser.download.dir”, Directory.GetCurrentDirectory() + “\\firefoxTemp”);
...
new FirefoxDriver(firefoxService, firefoxOptions);

var chromeOptions = new ChromeOptions();
chromeOptions.AddUserProfilePreference(“download.default_directory”, Directory.GetCurrentDirectory() + “\\chromeTemp”);
...
new ChromeDriver(chromeService, chromeOptions);
```

**Tarayıcı time out süresi ayarlama**

Default olarak timeout süreleri;\
For implicit waits: 0 seconds.\
For page loads: 300 seconds.\
For script timeouts: 30 seconds.

Aşağıdaki kod ile değiştirilebilir.

```csharp
Driver.Manage().Timeouts().ImplicitWait = TimeSpan.FromMinutes(1);
Driver.Manage().Timeouts().PageLoad = TimeSpan.FromMinutes(1);
Driver.Manage().Timeouts().AsynchronousJavaScript = TimeSpan.FromMinutes(1);
```

**Tarayıcı Penceresi gizli(headless) olduğunda dosya indirme**

Tarayıcı headless durumunda olduğunda dosya indirme işlemini yapamamaktadır. Aşağıdaki düzenlemenin yapılması gerekmektedir.\
Chrome için;

```csharp
static async Task AllowHeadlessDownloadChrome(ChromeDriverService driverService, IWebDriver Driver)
{
    var jsonContent = new JObject(
        new JProperty("cmd", "Page.setDownloadBehavior"),
        new JProperty("params",
        new JObject(new JObject(
            new JProperty("behavior", "allow"),
            new JProperty("downloadPath", Directory.GetCurrentDirectory() + BrowserOptionNames.ChromeTemp)))));
    var content = new StringContent(jsonContent.ToString(), Encoding.UTF8, "application/json");
    var sessionIdProperty = typeof(ChromeDriver).GetProperty("SessionId");
    var sessionId = sessionIdProperty.GetValue(Driver, null) as SessionId;

    using (var client = new HttpClient())
    {
        client.BaseAddress = driverService.ServiceUrl;
        await client.PostAsync("session/" + sessionId + "/chromium/send_command", content);
    }
}
```

Firefox için;

```csharp
static async Task AllowHeadlessDownloadFirefox(FirefoxDriverService driverService, IWebDriver Driver)
{
    var jsonContent = new JObject(
        new JProperty("cmd", "Page.setDownloadBehavior"),
        new JProperty("params",
        new JObject(new JObject(
            new JProperty("behavior", "allow"),
            new JProperty("downloadPath", Directory.GetCurrentDirectory() + BrowserOptionNames.FirefoxTemp)))));
    var content = new StringContent(jsonContent.ToString(), Encoding.UTF8, "application/json");
    var sessionIdProperty = typeof(FirefoxDriver).GetProperty("SessionId");
    var sessionId = sessionIdProperty.GetValue(Driver, null) as SessionId;

    using (var client = new HttpClient())
    {
        client.BaseAddress = driverService.ServiceUrl;
        await client.PostAsync("session/" + sessionId + "/geckodriver/send_command", content);
    }
}
```

Chrome ve Firefox için metodun kullanımı;

```csharp
protected IWebDriver SetBrowser(string browserName)
{
    if (browserName.Equals(BrowserOptionNames.Firefox))
    {
        var firefoxService = FirefoxDriverService.CreateDefaultService();
        firefoxService.HideCommandPromptWindow = true;

        var firefoxOptions = new FirefoxOptions();
        firefoxOptions.AddArguments(BrowserOptionNames.FirefoxHeadless);
        firefoxOptions.SetPreference("browser.download.folderList", 2);
        firefoxOptions.SetPreference("browser.download.useDownloadDir", true);
        firefoxOptions.SetPreference("browser.helperApps.neverAsk.saveToDisk", "application/pdf;application/vnd.ms-excel;application/vnd.ms-excel.addin.macroenabled.12;application/vnd.ms-excelsheet.binary.macroenabled.12;application/vnd.ms-excel.template.macroenabled.12;application/vnd.ms-excel.sheet.macroenabled.12");
        firefoxOptions.SetPreference("pdfjs.disabled", true);
        firefoxOptions.SetPreference(BrowserOptionNames.FirefoxDownload, Directory.GetCurrentDirectory() + BrowserOptionNames.FirefoxTemp);

        Driver = new FirefoxDriver(firefoxService, firefoxOptions);
        Task.Run(() => AllowHeadlessDownloadFirefox(firefoxService, Driver));
    }
    else if (browserName.Equals(BrowserOptionNames.Chrome))
    {
        var chromeService = ChromeDriverService.CreateDefaultService();
        chromeService.HideCommandPromptWindow = true;

        var chromeOptions = new ChromeOptions();
        chromeOptions.AddArguments(BrowserOptionNames.ChromeHeadless);
        chromeOptions.AddUserProfilePreference(BrowserOptionNames.ChromeDownload, Directory.GetCurrentDirectory() + BrowserOptionNames.ChromeTemp);

        Driver = new ChromeDriver(chromeService, chromeOptions);
        Task.Run(() => AllowHeadlessDownloadChrome(chromeService, Driver));
    }

    return Driver;
}
```
