From my lectures on angular documentation and other forums I ended up with the following configuration. In the config part of angular : $httpProvider.defaults.xsrfCookieName = 'csrftoken'; $httpProvider.defaults.xsrfHeaderName = 'X-CSRFToken'; $httpProvider

问题 I am writing a web application that saves POSTed data to a session in one page, then redirects to another page to utilize the created session information. This was after I read that the proper way to process data and display data is to separate them into two different scripts so as not to run into a redundant $_POST data issue. That is, not to keep $_POSTing the same data to the server every page refresh. I have a view page, index.php , and a data processing page, setDate.php . When viewing

问题 I'm looking for a way to log JSON posts in a RESTEASY framework. I woul like to log the POST body to log file to see what the client is sending to me. Is there any interceptor or something similar that I can use, I have found an example for PreProcessInterceptor but it looks like it is deprecated. I'm using resteasy 3.0.8 回答1: You can use a ContainerRequestFilter: @Provider public class LogFilter implements ContainerRequestFilter { private Logger LOG = LoggerFactory.getLogger(LogFilter.class)

问题 I have a simple question. I know that I can prevent a form to re-submit itself when the user reloads the page by using the Post/Redirect/Get Pattern. But my question is, will this pattern work if I'm redirecting the user back to the same page where the form was submitted? I mean, I don't want to redirect the user to another page. Any help please Thank you 回答1: yes, but you have to remember to redirect him without the GET params. so you can header('Location: same_page.php?status=done'); die();
