調用webservice接口，返回xml（String）轉義

import org.apache.commons.lang3.StringEscapeUtils; //依賴的包

StringBuilder content = new StringBuilder();
content.append("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
content.append("<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:ser=\"http://service.interfacemodule.lbcs.midea.com\">");

content.append("<soapenv:Body>");
content.append("<ser:doCheckQrcode>");
content.append("<ser:inParams><![CDATA[<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>");
content.append("<input><qrcode>").append(params.get("qrcode")).append("</qrcode>")
              .append("<checkCode>").append(params.get("checkCode")).append("</checkCode></input>]]></ser:inParams>");
content.append("</ser:doCheckQrcode>").append("</soapenv:Body>").append("</soapenv:Envelope>");

System.out.println(content.toString());
