StringWriter writer = new StringWriter() ", and copies it into the string named EncodedString as "This+is+a+%3cTest+String%3e.". It encodes the string named TestString, which contains the text "This is a. The following example encodes a string for transmission by HTTP. The TextWriter output stream that contains the encoded string. Outside of a web application, use the WebUtility class to encode or decode values. In a class that is not in a code-behind file, use to access an instance of the HttpServerUtility class. In the code-behind file for an ASP.NET web page, access an instance of the HttpServerUtility class through the Server property. Internally, this method uses HttpUtility.UrlEncode to encode strings. This method is a convenient way to access the HttpUtility.UrlEncode method at run time from an ASP.NET application. As a result, these characters must be encoded in tags or in query strings where the strings can be re-sent by a browser in a request string. Characters such as a question mark (?), ampersand (&), slash mark (/), and spaces might be truncated or corrupted by some browsers. URL encoding ensures that all browsers will correctly transmit text in URL strings. Return "~/Finish?url=" + (destinationURL)
#Url encode for return how to
The next example is similar to the previous example except it shows how to URL-encode a value from within a class that is not in the code-behind file. NextPage.NavigateUrl = "~/Finish?url=" + Server.UrlEncode(destinationURL) Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load Protected void Page_Load(object sender, EventArgs e)
Typically, you would URL-encode a value that you received from the user or the request. The value to encode is hard-coded in this example only to simplify the example and show the type of value you might URL-encode.
#Url encode for return code
The code resides in the code-behind file for a web page. Please fix the auto-urldecode of $_GET var in the next PHP version. $x store: in the first case "º" (good) and in the second case "º" (good) $x store: in the first case "�" (bad) and in the second case "º" (good) In this scenary, you assign the value into variable $x When the client send Get data, utf-8 character encoding have a tiny problem with the urlencode.įoo.php?myvar=%C2%BA (The "right" url encoding)
This mean you should &entitify all &-s in any other HTML attributes as well, such as in a form with Note that the decoding of & to & is done in the browser, and it's done right after splitting the HTML into tags, attributes and content, but it works both for attributes and content. The result will be the same as if you had inserted the actual character into your source code, for instance by pressing alt-0169 and actually inserted ? in your HTML. The reason why & works "most of the time" is that browsers are forgiving and just decode the & as the &-sign. This breaks whenever you have a variable that matches an HTML entity, like "gt" or "copy" or whatever. © in your URL will be interpreted as © (the is not mandatory in SGML as it is "implied". In XML it is mandatory.). Instead, do what all HTML standards says and encode & in URLs as & in your HTML. $decodedStr .= htmlentities(utf8_decode($dechex)) This seems to decode correctly between most browsers and charater coding configurations. Specially indicated for direct parsing of URL as it comes on environment variables:
