SWT 浏览器 - 它使用哪个浏览器?

问题描述

如果安装了多个浏览器,如何判断 SWT 浏览器使用的是哪个操作系统浏览器?

我特别询问 Windows 和 OSX。

这与Clear SWT Browser cache有关。

解决方法

使用 browser.getBrowserType() 方法。见:https://help.eclipse.org/2020-12/topic/org.eclipse.platform.doc.isv/reference/api/org/eclipse/swt/browser/Browser.html#getBrowserType()


// ... your code

final var browser = new Browser(shell,SWT.NONE);

browser.setUrl("https://www.google.com/");

/** 
 * Description: Returns the type of native browser being used by this instance. Examples: 
 * "ie","mozilla","voyager","webkit"
 */
System.out.println(browser.getBrowserType());


JS 解决方案:Find browser type/version of SWT Browser


// ... your code

final var browser = new Browser(shell,SWT.NONE);

browser.setUrl("https://www.google.com/");

System.out.println(browser.evaluate("var ua = navigator.userAgent,tem,M = ua.match(/(opera|chrome|safari|firefox|msie|trident(?=\\/))\\/?\\s*(\\d+)/i) || []; if (/trident/i.test(M[1])) { tem = /\\brv[ :]+(\\d+)/g.exec(ua) || []; return 'IE ' + (tem[1] || ''); } if (M[1] === 'Chrome') { tem = ua.match(/\\b(OPR|Edge)\\/(\\d+)/); if (tem != null) return tem.slice(1).join(' ').replace('OPR','Opera'); } M = M[2] ? [M[1],M[2]] : [navigator.appName,navigator.appVersion,'-?']; if ((tem = ua.match(/version\\/(\\d+)/i)) != null) M.splice(1,1,tem[1]); return M.join(' ');"));
