What are XML-RPC requests?
XML-RPC requests are a combination of XML content and HTTP headers. The XML content uses the data typing structure to pass parameters and contains additional information identifying which procedure is being called, while the HTTP headers provide a wrapper for passing the request over the Web.
Do you know what the XML-RPC protocol is?
XML-RPC is among the simplest and most foolproof web service approaches that makes it easy for computers to call procedures on other computers. XML-RPC permits programs to make function or procedure calls across a network. XML-RPC uses the HTTP protocol to pass information from a client computer to a server computer.
Why is it bad to use RPC in XML?
XML-RPC was problematic, because ensuring data types of XML payloads is tough. In XML, a lot of things are just strings, so you need to layer meta data on top in order to describe things such as which fields correspond to which data types. This became part of the basis for SOAP (Simple Object Access Protocol).
What does RPC stand for in HTTP API?
XML-RPC and SOAP, along with custom homegrown solutions, dominated the API landscape for a long time and were all RPC-based HTTP APIs. The “RPC” part stands for “remote procedure call,” and it’s essentially the same as calling a function in JavaScript, PHP, Python and so on, taking a method name and arguments.
What kind of RPC was used before rest?
Before REST became popular (after companies such as Twitter and Facebook labeled their APIs as REST), most APIs were built using an XML-RPC or SOAP. XML-RPC was problematic, because ensuring data types of XML payloads is tough.
Can a JSON-RPC protocol be used for RPC?
Seeing as XML is not everyone’s cup of tea, an RPC API could use the JSON-RPC protocol, or you could roll a custom JSON-based API, as Slack has done with its Web API. Take this example RPC call: In JavaScript, we would do the same by defining a function, and later we’d call it elsewhere:
