User input the url string in a textbox and I need to add a string "cmd" if not available .
Please suggest how to achieve this,
string cmdUrl = AddPrefix("https://google.com");
static string AddPrefix(string inputUrl)
{
return formattedUrl;// want to return https://cmd.google.com if the string cmd not added already in url
}
First, you can parse your url using var parsedUrl = new Uri(inputUrl).
Then check if the host includes your substring like this: parsedUrl.Host.StartsWith("cmd")
If it does, return your original url else build your new one: $"{parsedUrl.Scheme}://cmd.{parsedUrl.Host}{parsedUrl.PathAndQuery}"
here I am getting the url of the previous page.
LookUpDict.driver.FindElementByXPath("//*[#id='ns__30899058_jsel_div1_contextMenu_alertsdijit_Menu_5_menuItem_1_CreateTicket_ProxyHFC']").Click();
String ticketUrl = LookUpDict.driver.Url;
LookUpDict.driver.Navigate().GoToUrl(ticketUrl);
public void CurrentUrl() {
String pURL = driver.getCurrentUrl();
driver.findElement(By.xpath(“<xpath>“)).click();
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
String cURL = driver.getCurrentUrl();
if(pURL!= return){
System.out.println(cURL);
}
else{
System.out.println(“No new URl”);
}
}
You are getting the URL after the click which is after the navigate happens. If you want to get the URL before the navigation/click you need to rearrange your code.
String ticketUrl = LookUpDict.driver.Url;
LookUpDict.driver.FindElementByXPath("//*[#id='ns__30899058_jsel_div1_contextMenu_alertsdijit_Menu_5_menuItem_1_CreateTicket_ProxyHFC']").Click();
LookUpDict.driver.Navigate().GoToUrl(ticketUrl);
You can also just use Driver.Navigate().Back(); to avoid having to store the previous URL.
protected void ConnectToFaceBook_btn_Click(object sender, EventArgs e)
{
string url = System.Uri.EscapeDataString("http://localhost:1298/FacebookChatApi/Default2.aspx");
string clientID = "507061112747022";
string redirecturl = #"https://graph.facebook.com/oauth/authorize?client_id="+clientID+"&redirect_uri="+url;
Response.Redirect(redirecturl);
GetAccessToken();
}
As you can see I am calling GetAccessToken() after Response.Redirect the given URL will return a query string called code and GetAccessToken. I am reading this query string but as I am doing it everything after Response.Redirect is not being executed. Is there any work around to call the redirecturl and get the code value without using Response.redirect?
there is a program in linux,php,python and etc called curl that act like a browser in your program, curl in C# have some alternative that u can use them curl in C# have some alternative that u can use them.
I'm working on a project that call a WebMethod dynamically after validating its parameters by knowing its URL.
Here's my attempt:
[WebMethod]
public string CalledService (string myText, int count)
{
return myText;
}
and all I know is its URL
http://localhost:29740/OnewayWebserviceCall/WebService.asmx?op=CalledService
I need a function that returns something like {"myText","count"}
I tried to download the URL string and search for the parameters in it but I need something more time efficient.
Somewhere in the url there is a &sortBy=6 . How do I update this to &sortBy=4 or &sortBy=2 on a button click? Do I need to write custom string functions to create the correct redirect url?
If I just need to append a query string variable I would do
string completeUrl = HttpContext.Current.Request.Url.AbsoluteUri + "&" + ...
Response.Redirect(completeUrl);
But what I want to do is modify an existing querystring variable.
To modify an existing QueryString value use this approach:
var nameValues = HttpUtility.ParseQueryString(Request.QueryString.ToString());
nameValues.Set("sortBy", "4");
string url = Request.Url.AbsolutePath;
Response.Redirect(url + "?" + nameValues); // ToString() is called implicitly
I go into more detail in another response.
Retrieve the querystring of sortby, then perform string replace on the full Url as follow:
string sUrl = *retrieve the required complete url*
string sCurrentValue = Request.QueryString["sortby"];
sUrl = sUrl.Replace("&sortby=" + sCurrentValue, "&sortby=" + newvalue);
Let me know how it goes :)
Good luck
private void UpdateQueryString(string queryString, string value)
{
PropertyInfo isreadonly = typeof(System.Collections.Specialized.NameValueCollection).GetProperty("IsReadOnly", BindingFlags.Instance | BindingFlags.NonPublic);
isreadonly.SetValue(this.Request.QueryString, false, null);
this.Request.QueryString.Set(queryString, value);
isreadonly.SetValue(this.Request.QueryString, true, null);
}
If you really want this you need to redirect to new same page with changed query string as already people answered. This will again load your page,loading page again just for changing querystring that is not good practice.
But Why do you need this?
If you want to change the value of sortBy from 6 to 4 to use everywhere in the application, my suggession is to store the value of query string into some variable or view state and use that view state everywhere.
For e.g.
in Page_Load you can write
if (!IsPostBack)
{
ViewState["SortBy"] = Request.QueryString["sortBy"];
}
and everywhere else ( even after postback ) you can use ViewState["SortBy"]
Based on Ahmad Solution I have created following Method that can be used generally
private string ModifyQueryStringValue(string p_Name, string p_NewValue)
{
var nameValues = HttpUtility.ParseQueryString(Request.QueryString.ToString());
nameValues.Set(p_Name, p_NewValue);
string url = Request.Url.AbsolutePath;
string updatedQueryString = "?" + nameValues.ToString();
return url + updatedQueryString;
}
and then us it as follows
Response.Redirect(ModifyQueryStringValue("SortBy","4"));
You need to redirect to a new URL. If you need to do some work on the server before redirecting there you need to use Response.Redirect(...) in your code. If you do not need to do work on the server just use HyperLink and render it in advance.
If you are asking about constructing the actual URL I am not aware of any built-in functions that can do the job. You can use constants for your Paths and QueryString arguments to avoid repeating them all over your code.
The UriBuilder can help you building the URL but not the query string
You can do it clientside with some javascript to build the query string and redirect the page using windows.open.
Otherwise you can use Response.Redirect or Server.Transfer on the server-side.
SolrNet has some very helpful Url extension methods. http://code.google.com/p/solrnet/source/browse/trunk/SampleSolrApp/Helpers/UrlHelperExtensions.cs?r=512
/// <summary>
/// Sets/changes an url's query string parameter.
/// </summary>
/// <param name="helper"></param>
/// <param name="url">URL to process</param>
/// <param name="key">Query string parameter key to set/change</param>
/// <param name="value">Query string parameter value</param>
/// <returns>Resulting URL</returns>
public static string SetParameter(this UrlHelper helper, string url, string key, string value) {
return helper.SetParameters(url, new Dictionary<string, object> {
{key, value}
});
}
The only way you have to change the QueryString is to redirect to the same page with the new QueryString:
Response.Redirect("YourPage.aspx?&sortBy=4")
http://msdn.microsoft.com/en-us/library/a8wa7sdt(v=vs.100).aspx
I think you could perform a replacement of the query string in the following fashion on your server side code.
NameValueCollection filtered = new NameValueCollection(request.QueryString);
filtered.Remove("SortBy");
filtered.Add("SortBy","4");
The query string is passed TO the server. You can deal with the query string as a string all you like - but it won't do anything until the page is ready to read it again (i.e. sent back to the server). So if you're asking how to deal with the value of a query string you just simply access it Request.QueryString["key"]. If you're wanting this 'change' in query string to be considered by the server you just need to effectively reload the page with the new value. So construct the url again page.aspx?id=30 for example, and pass this into a redirect method.
