XML-RPC data collection

XML-RPC is a XML-based Remote Call, its mechanism can see the following picture

I think the advantage of XML-RPC is that the HTTP protocol transmission over the internet, you only need a browser to easily call. In addition, due to the unified XML standards, platform-independent and language-independent implementations can be achieved. No matter what your platform or language is, there are corresponding XML-RPC. However, the disadvantages are also obvious: the efficiency is not high, and the network transmission security should be considered.
