escape in ABAP and JavaScript

日期：2020-02-29点击：698

ABAP

IF_HTTP_UTILITY~ESCAPE_URL

JavaScript

开源的sanitizer库，Google搞的。

https://www.npmjs.com/package/sanitizer
sanitizer.escape('your dirty string');
用于C4C：

在Java里使用这个JS library:

public class CajaSanitiser { private final ScriptEngine engine; private final Bindings bindings; public CajaSanitiser() throws IOException, ScriptException { this.engine = new ScriptEngineManager().getEngineByName("js"); this.bindings = engine.getBindings(ScriptContext.ENGINE_SCOPE); String scriptName = "com/google/caja/plugin/html-css-sanitizer-minified.js"; try (BufferedReader reader = getReader(scriptName)) { engine.eval(reader); } String identity = "function identity(value) {return value;}"; engine.eval(identity); } private BufferedReader getReader(String name) { return new BufferedReader(new InputStreamReader( getClass().getClassLoader().getResourceAsStream(name))); } public String sanitise(String htmlSource) throws ScriptException { bindings.put("src", htmlSource); // You can use other functions beside 'identity' if you // want to transform the html. // See https://code.google.com/p/google-caja/wiki/JsHtmlSanitizer return (String) engine.eval("html_sanitize(src, identity, identity)"); } public static void main(String[] args) throws Exception { CajaSanitiser sanitiser = new CajaSanitiser(); String source = "<html>\n" + "<head>\n" + "<style>\n" + "h1 {color:blue;}\n" + "</style>\n" + "</head>\n" + "<body>\n" + "<h1>A heading</h1>\n" + "</body>\n" + "</html>"; System.out.println("Original HTML with CSS:"); System.out.println(source); System.out.println(); System.out.println("Sanitised HTML:"); System.out.println(sanitiser.sanitise(source)); } }
