Send XML

Use the URL encapsulation path to open an httpurlconnection

Set the request method, content-type, and Content-Length.

The XML file's Content-Type is: text/XML; charset = UTF-8

Use httpurlconnection to obtain output stream output data

WebService

WebService is an API published on the network. It can be called by sending XML, and the results returned by WebService are also XML data.

WebService has no language restrictions. You only need to send XML data and receive XML data.

The http://www.webxml.com.cn website provides some WebService services that we can call

Http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx? OP = getmobilecodeinfo

The content is as follows:
