Android - Get status codes of web pages opened in browser


By : Terry
Date : September 16 2020, 02:00 PM
may help you . In desktop browsers, an extension can trivially obtain the status codes of web pages opened in the browser. By status code I mean 200, 302, 404, 502 etc ... , Sample 1:
code :
URL url = new URL("http://example.com");
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.setRequestMethod("GET");
connection.connect();
int code = connection.getResponseCode(); // show code result :)
URL url = new URL("http://www.google.com/humans.txt");
HttpURLConnection http = (HttpURLConnection)url.openConnection();
int statusCode = http.getResponseCode(); // show result :)

Cross-browser support / implementation of HTTP status codes

may help you . I'll have to answer my own question here, though the research didn't provide a whole lot of usefull stuff. The best I could find was Redirect in response to POST transaction, which seems a little bit outdated.
After all, I'll have to compile a list myself, I'm afraid.

Status Codes of web pages

may help you . You can ask for the StatusCode only after you made a call to the GetResponse() method. You need to wrap GetResponse() in a try/catch block. Have a look at Check if a url is reachable - Help in optimizing a Class.
If you just want to test for server reachability then you may use a Ping.

Different server & browser HTTP status codes

I wish did fix the issue. Yes - the server is able to serve the page ok so returns 200, but the client cannot finish the connection.
It could be a part of your infrastructure (firewall?) is choosing to update or something, although the odds of this happening at the exact same time of your request is slim unless it's a long running request or gateway outage.

Spring filters cannot see status codes for requests to static pages

hope this fix your issue I ended up posting an issue on Github: https://github.com/spring-projects/spring-boot/issues/2817 The answer was embarrassingly simple: I needed to log the response status after invoking filterChain.doFilter:
code :
@Override
protected void doFilterInternal(HttpServletRequest request,     HttpServletResponse response, FilterChain filterChain)
    throws ServletException, IOException {
filterChain.doFilter(request, response);
LOGGER.info("HTTP request for resource {} - status {}", request.getRequestURI(), response.getStatus());
}

Serving Up Pages for HTTP Status Codes

hope this fix your issue I'm trying to set up 500 and 404 pages for an ASP.NET 4.5.2 Web Forms project. I've got the 404 working when the non-existent page is a .ASPX page. - I have code written to serve up a custom NotFound.aspx page in response. , I was able to solve it as follows:
code :
<httpErrors errorMode="Custom" existingResponse="Replace">
    <remove statusCode="404" />
    <error statusCode="404" path="http://localhost/myproject/404.html"
        responseMode="File" />
</httpErrors>
