URL Transcode
Description
URL encoding stands for encoding certain characters in a URL. The url_transcode part does this by replacing them with one or more character triplets that consist of the percent character "%" followed by two hexadecimal digits. The two hexadecimal digits of the triplet(s) represent the numeric value of the replaced character. The part also helps you decode a url.
Use
When you pass information through a URL, you need to make sure it only uses specific allowed characters like: alphabetic characters, numerals, and a few special characters that have meaning in the URL string. Any other characters should be encoded so that they don't cause problems. Any character that is not an alphabetic character, a number or a special character that is being used outside its normal context should be encoded.
The part can be created with the folllowing steps:
- Open the designer
- Right click
- Select "add node"
- Select "Process" (depends on the framework: you may also need to select "url_transcode" from the popup menu)
- Double click on the added node (A menu will pop-up on right hand side, if the project is based on the framework, you may see the options of the url_transcode part already without needing the following step 6.)
- Insert a "url_transcode " from the opened menu
- Save
