Example Usage

static void Main(string[] args)
{
    /* Initialize Browser */
    Browser browser = new Browser();

    /* Navigate to a website */
    IDocument document = browser.Navigate("https://www.browsesharp.org/testsitesforms.html");

    / * Navigate with headers */
    Dictionary<string, string> headers = new Dictionary<string, string>();
    headers.Add("x-csrf-token", "2342342");
    var response = browser.Navigate(RequestTesterRouteUri, headers);

    /* Navigate with data */
    Dictionary<string, string> formData = new Dictionary<string, string>();
    formData.Add("Username","FakeUserName");
    formData.Add("Password", "FakePassword123");
    formData.Add("SecretMessage", "This is a secret message");
    var response = browser.Navigate(RequestTesterRouteUri, headers, formData);



    /* SubmitForm */
    /* Form */
    browser.Navigate("https://www.browsesharp.org/testsitesforms.html");
    Form postForm = browser.Document.Forms[0];
    postForm.SetValue("UserName", "TestUser");
    postForm.SetValue("Password", "TestPassword");
    IDocument postResponse = browser.SubmitForm(postForm);
    
    /* Form as dictionary */
    var response = browser.Submit("https://www.hashemian.com/tools/form-post-tester.php", formData);
    
    /* With headers */
    var response = browser.Submit("https://requesttester.com", formData, headers);


    /* Async calls */
    var response = await browser.NavigateAsync("https://www.browsesharp.org/testsitesforms.html");


    /* Get current document */
    IDocument lastDocument = browser.Document;


    /* Typed Responses 
        Note: Request is a custom class unrelated to this library
    */
    /* Make request that is deserialized into a request object */
    IDocument<Request> response = browser.Navigate<Request>(RequestTesterRouteJsonUri, headers, formData);
    Request request = response.Data; /* Get the Request object from the response */



    /* Run script - This will be cleaned up! */
    browser.JavascriptEngine.Document = browser.Documents[0].Scripts[2].JavascriptString;
    var result = browser.JavascriptEngine.Execute("w3CodeColor();");

    /* Output */
    Document requestedDocument = browser.Documents[0];
    Console.WriteLine("Scraped Scripts: " + requestedDocument.Scripts.Count);
    Console.WriteLine("Scraped Styles: " + requestedDocument.Styles.Count);
    Console.WriteLine("Begining of document: " + requestedDocument.Response.Content.Substring(0, 60));

}

Unit Tests:

  • With version 0.0.3 unit tests now utilize the RequestTester node.js application which can be found on my github page.
