This code will check my link is broken or not and validateWebResourceUrl method will return 0 status .even if i get 200 status my link couldn't redirect to mozilla firefox when i call my api call.Below code will show u my api cal.
@RequestMapping(method = RequestMethod.POST, value = "/validate/fburl")
public ModelAndView validateFbLink(HttpServletRequest request,@RequestParam(value="key", required=true) String key ,@RequestParam(value = "link") String link, HttpServletResponse response) throws Exception {
ModelAndView jsonmodel = new ModelAndView("rest/model");
jsonmodel.addObject("model", httpFrameBreakChecker.validateHttpLink(link, key));
return jsonmodel;
}
此 api 调用将检查链接是否损坏，如果没有，它将转到重定向。我正在尝试查找损坏的链接，我得到该链接的状态 200，但该链接没有重定向。下面是我的代码.
package org.ednovo.gooru.util;
import org.springframework.stereotype.Component;
import com.gargoylesoftware.htmlunit.BrowserVersion;
import com.gargoylesoftware.htmlunit.WebClient;
import com.gargoylesoftware.htmlunit.WebResponse;
@Component
public class HttpFrameBreakChecker extends LinkChecker {
@Override
public Integer validateHttpLink(String resourceUrl, String key) {
Integer status = null;
status = validateWebResourceUrl(resourceUrl, getPageTesterPath());
putResourceStatus(status, key);
return status;
}
public synchronized Integer validateWebResourceUrl(String webURL, String pageTesterURL) {
WebClient webClient = null;
WebResponse webResponse = null;
try {
webClient = new WebClient(BrowserVersion.FIREFOX_3_6);
webClient.setCssEnabled(false);
webClient.setThrowExceptionOnScriptError(false);
webResponse = webClient.getPage(webURL).getWebResponse();
int i = webResponse.getStatusCode();
logger.info(i+"");
if (webResponse.getStatusCode() != 200) {
return null;
}
String urlToCheck = webURL + pageTesterURL;
// Now check if the page has a frame breaker.
webResponse = webClient.getPage(urlToCheck).getWebResponse();
int status = webResponse.getStatusCode();
logger.info(status+""+"frame");
String pageURL = webResponse.getWebRequest().getUrl().toString();
int validationStatus = (urlToCheck.equals(pageURL) && status == 200) ? 0 : 1;
logger.info(validationStatus+ " return statement of validateWebResourceUrl ");
return validationStatus;
} catch (Exception exception) {
logger.error("ERROR : Unable to start web driver : " + exception.getMessage());
return null;
} finally {
try {
if (webClient != null) {
webClient.closeAllWindows();
}
} catch (Exception ex) {
}
}
}
@Override
public void commitPage() {
if (resources.size() > 0) {
String resourcesString = getxStream().toXML(resources);
postData(getApiPath(), "/resource/urls/update/frameBreaker/" + getGlobalJobKey(), resourcesString);
postData(getSearchApiPath(), "/search/resource/update/index/" + getGlobalJobKey(), resourcesString );
}
}
@Override
public String getType() {
return "FB";
}
}
And Below code will show you the LinkChecker class.
