![]() What you’re looking at is something called a “base 64 encoded data URL.” This is a fairly new thing that’s been introduced in HTML5, and you can use it not only for images, but for CSS files and JavaScript. Because the images are essentially loaded with the page, the display is instantaneous when your browser loads the view. In fact, if you watch in the Web debugger when loading the page, you’ll see that 100% of the time, the Google logo is loaded from the cache at high speed every time. That’s the Google logo that displays front and center in the page when you load it. Pay close attention to the section in the red rectangle. You’ll see something like this:įigure 1: Google search uses Base64-encoded images If you’re in any doubt about the validity of this scheme, take a look at the source for Google’s current search page. What you could do is to embed your images directly into your Web page and then transmit them all at the same time when delivering the original page. Yes it does, but let’s imagine for a moment you wanted to try and save a few requests in your latest ASP.NET MVC project. ![]() HTTP Allows Transmission of Binary, Right? It’s great for encoding complex binary files and data into a very simple textual representation that transmits exceptionally easy across text-based protocols such as HTTP. Well, it turns out that Base64 encoding actually does still have one very good use. Okay, So if It’s Rubbish, Why Am I Telling You about It? Base64 is a two-way cipher so as long as you have the original phrase, it’s easy to reverse it back and get the original text back out of it. If you ask anyone these days, however, for a serious point of view on using it, you’ll likely get laughed at. Base64 is the encryption format used by browsers when implementing very simple username and password form of basic authentication. Through this blog, I want to share my expertise in SAP technical areas such as SAP ABAP, PI/PO, AIF, and Basis.If you’ve done anything long term in the Web industry, it’s likely that you will have come across “Base64 Encoding” at some point. Having the opportunity to work on SAP implementation projects in USA, EU, and Asia, I learned valuable ins and outs of global business processors in Sales and Distribution (SD), Material Management, Retail, Customer Relationship Management (CRM), and Finance and Controlling (FICO). Playing a variety of roles from an offshore technical consultant (ABAP, PI/PO, BW, BOBJ) at the beginning of my career to a technical lead managing a team of consultants in different countries, I have gained immense experience in SAP project implementation life cycle. I started my carrier as an ABAP developer and soon found my love for system integration when I learned SAP XI 3.0 in 2008. Hi, I am Isuru Fernando, Senior SAP Integration Consultant with 10 years of SAP full-cycle implementation and support project experience.įrom the early days, I had a passion for coding, software development, and everything tech-related. UDF converts this value to Base64 format.Įncoding can be broken down to two steps, Step 1: Convert String to Byte Arrayįirst, input string value is converted to byte array using String method getBytes(). Input value is assigned from the source message element “PlainString”. This class contains two nested classes: Base64.Decoder decodes byte data and Base64.Encoder implements the encoder for encoding byte data.Įncoding UDF has one input variable “PlainString”. For example, Base64 decoding UDF accepts Base64 encoded string as the input and returns the encoded string.īoth encoding and decoding will be carried out using standard methods of Java utility class 64. That means the UDF accepts only one argument as input and outputs one value. We will implement two UDFs, one to encode Base64 and another one to decode Base64.īoth UDFs have an Execution Type of “ Single Value“. This example will be implemented in an SAP Process Orchestration (PO) system version SAP PO 7.50 single stack.ĭesign of the Base64 Encoding and Decoding UDFs: One field contains the Base64 encoded string and the other field contains the string we need to encode to Base64. Let’s assume, we have a source XML message with two fields. SAP PO 7.5 Encoding and Decoding Example Overview:.In SAP Back-end system the same functionality can be achieved using ABAP Function Modules or ABAP class CL_HTTP_UTILITY. You can also use Java Mapping class to encode or decode Base64 format. In this post, we will discuss how to convert Base64 using User Defined Functions (UDF). There are several ways to encode and decode Base64 messages in SAP PI/PO.
