ContextFilter ContextFilter org.ofbiz.webapp.control.ContextFilter disableContextSecurity N allowedPaths /error:/control:/select:/index.html:/index.jsp:/default.html:/default.jsp:/images:/static:/js errorCode 403 redirectPath /control/main
1.allowedPaths参数
该参数的初始化如下
首先可以看到的是每次新的request过来都会被解析allowedPath,也许这里可以优化一下
if (request.getAttribute(ContextFilter.FORWARDED_FROM_SERVLET) == null) { // Debug.logInfo("In ContextFilter.doFilter, FORWARDED_FROM_SERVLET is NOT set", module); String allowedPath = config.getInitParameter("allowedPaths"); String redirectPath = config.getInitParameter("redirectPath"); String errorCode = config.getInitParameter("errorCode"); ListallowList = StringUtil.split(allowedPath, ":"); allowList.add("/"); // No path is allowed. allowList.add(""); // No path is allowed.
往下点代码有类似这样的一段
if (!allowList.contains(requestPath) && !allowList.contains(requestInfo) && !allowList.contains(httpRequest.getServletPath())) {
这是说当request的资源名不位于allowedPath 中
那么接下去是
String filterMessage = "[Filtered request]: " + contextUri; if (redirectPath == null) { int error = 404; if (UtilValidate.isNotEmpty(errorCode)) { try { error = Integer.parseInt(errorCode); } catch (NumberFormatException nfe) { Debug.logWarning(nfe, "Error code specified would not parse to Integer : " + errorCode, module); } } filterMessage = filterMessage + " (" + error + ")"; wrapper.sendError(error, contextUri); } else { filterMessage = filterMessage + " (" + redirectPath + ")"; if (!redirectPath.toLowerCase().startsWith("http")) { redirectPath = httpRequest.getContextPath() + redirectPath; } wrapper.sendRedirect(redirectPath); } Debug.logWarning(filterMessage, module); return; }
wrapper.sendRedirect(redirectPath);这句会把你给重定向到其他地方。
redirectPath是我们上面配置的
redirectPath /control/main
一般都是配置为重定向/control/main。
如果我们把/control从allowedPaths删除掉就会发现请求不断被重定向到/control/main。最后ko了。。。。。
