When directly accessing a URL which use Route::post(), Laravel shows the following 405 Method Not Allowed error screen:
Oops! An Error Occurred
The server returned a "405 Method Not Allowed".
Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.
I think it is not good to give bad people information about the correct method. Am I right?
How to hide 405 Method Not Allowed error screen and show 404 Not Found error instead?
It is better to configure .env or Laravel than to configure nginx or apache.
And I don't want to write 404 error redirect in every controller methods.
I want to hide the error screen only in the production because it is good to know that method is not correct while developing (debug mode is on).
Thanks to #Don'tPanic in the comments of my question, I found the answer.
Laravel offers the option to hide 405 error screen.
You can change 405 error to 404 error and display 404 Not Found error page instead of 405 error page without writing code in every controller action method.

The Render Method
https://laravel.com/docs/5.8/errors#render-method
An AJAX HTTP request terminated abnormally.
Debugging information follows.
Path: htps://MYSITE/index.php?q=user/autocomplete
StatusText:
ResponseText:
ReadyState: 4
I get that error when I try to type in the autocomplete box that is installed from core drupal.
I've read up on documentation on patching these files https://www.drupal.org/node/1232416 and did so.
In my console I get an error of :
XMLHttpRequest cannot load htps://SITE_B. Redirect from htps://ANOTHERSITE' to 'htps://SITE_B' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'htps://MYSITE' is therefore not allowed access.
So I researched CORS and added htp://stackoverflow.com/questions/13421463/htaccess-access-control-allow-origin
suggestion about .htaccess but to no avail.
I'm running drupal 7.51 on Dev Desktop 2 on a localhost. As well I have it running live, but want to fix it locally first. Any suggestions will help, I've research for hours now.
After countless hours and cold showers, I found out my answer. There was a bad php script in one of the nodes that used Drupal_goto(). That is how I got XMLHttpRequest. I followed https://drupal.stackexchange.com/questions/22825/how-to-find-bad-php-node-that-makes-search-cron-fail to find out where my php script failed me at.
In the firebug i can see all xmlHttprequests if i check the it in the console options like this
But my site has many js files like 40 and i have to scroll down to see if i get any ajax error in get in red color.
Is there any way to just get those error only.
I tried javascript errors but dont catch any erorr in GET request
That may not answer exactly to your needs, but here is how I usually proceed.
Use the Net panel, and use the "XHR" filter, and then sort by "status".
Every requests that have a status >= 400 have failed. Also see http://en.wikipedia.org/wiki/List_of_HTTP_status_codes
Thus every XHR errors are gathered at the bottom.

I have a web application that crashes on ajax requests with google chrome (it works with every other web browser it was tested it). After debugging I found that the error is caused by response.responseText being undefined. The xhr object looks like this:
argument: undefined
isAbort: false
isTimeout: undefined
status: 0
statusText: "communication failure"
tId: 3
In debugger in the 'network' tab I get "(failed)", however all the headers are there and I can even copy into clipboard the response body (which is a valid JSON).
My question is - how can I debug this problem? Where to find additional information, what causes this request to fail?
I finally found the solution to my problem : AdBlocks, when it blocks an ajax request, it just says "communication failure".
The first thing I would double-check is that the data coming back from the response is valid JSON. Just pass it through a JSON validator like this online JSONLint: http://jsonlint.com/
I assume that you are using something like jQuery to make your AJAX requests. If so, then make sure that you are using the development version of that library. Now that you are using the development version (uncompressed) of the script, find the particular function that you are using (eg. $.ajax) and then, within the Chrome inspector, insert a breakpoint in the code where the AJAX response is first handled (eg. https://github.com/jquery/jquery/blob/master/src/ajax.js#L579). Then proceed to step through the code, inspecting various return-values to see exactly what is going wrong.
If you are not using something like jQuery to make AJAX calls, then I'd recommend using a framework to avoid possible cross-browser compatibility issues like you might be experiencing right now.
For some reason, while using AJAX (with my dashcode developed application) the browser just stops uploading and returns status codes of 0. Why does this happen?
Another case:
It could be possible to get a status code of 0 if you have sent an AJAX call and a refresh of the browser was triggered before getting the AJAX response. The AJAX call will be cancelled and you will get this status.
In my experience, you'll see a status of 0 when:
doing cross-site scripting (where access is denied)
requesting a URL that is unreachable (typo, DNS issues, etc)
the request is otherwise intercepted (check your ad blocker)
as above, if the request is interrupted (browser navigates away from the page)
Same problem here when using <button onclick="">submit</button>. Then solved by using <input type="button" onclick="">
Status code 0 means the requested url is not reachable. By changing http://something/something to https://something/something worked for me. IE throwns an error saying "permission denied" when the status code is 0, other browsers dont.
It is important to note, that ajax calls can fail even within a session which is defined by a cookie with a certain domain prefixed with www. When you then call your php script e.g. without the www. prefix in the url, the call will fail and viceversa, too.
Because this shows up when you google ajax status 0 I wanted to leave some tip that just took me hours of wasted time... I was using ajax to call a PHP service which happened to be Phil's REST_Controller for Codeigniter (not sure if this has anything to do with it or not) and kept getting status 0, readystate 0 and it was driving me nuts. I was debugging it and noticed when I would echo and return instead of exit the message I'd get a success. Finally I turned debugging off and tried and it worked. Seems the xDebug debugger with PHP was somehow modifying the response. If your using a PHP debugger try turning it off to see if that helps.
I found another case where jquery gives you status code 0 -- if for some reason XMLHttpRequest is not defined, you'll get this error.
Obviously this won't normally happen on the web, but a bug in a nightly firefox build caused this to crop up in an add-on I was writing. :)
This article helped me. I was submitting form via AJAX and forgotten to use return false (after my ajax request) which led to classic form submission but strangely it was not completed.
"Accidental" form submission was exactly the problem I was having. I just removed the FORM tags altogether and that seems to fix the problem. Thank you, everybody!
I had the same problem, and it was related to XSS (cross site scripting) block by the browser. I managed to make it work using a server.
Take a look at: http://www.daniweb.com/web-development/javascript-dhtml-ajax/threads/282972/why-am-i-getting-xmlhttprequest.status0
We had similar problem - status code 0 on jquery ajax call - and it took us whole day to diagnose it. Since no one had mentioned this reason yet, I thought I'll share.
In our case the problem was HTTP server crash. Some bug in PHP was blowing Apache, so on client end it looked like this:
mirek#toccata:~$ telnet our.server.com 80
Trying 180.153.xxx.xxx...
Connected to our.server.com.
Escape character is '^]'.
GET /test.php HTTP/1.0
Host: our.server.com
Connection closed by foreign host.
mirek#toccata:~$
where test.php contained the crashing code.
No data returned from the server (not even headers) => ajax call was aborted with status 0.
In my case, it was caused by running my django server under http://127.0.0.1:8000/ but sending the ajax call to http://localhost:8000/. Even though you would expect them to map to the same address, they don't so make sure you're not sending your requests to localhost.
In our case, the page link was changed from https to http. Even though the users were logged in, they were prevented from loading with AJAX.
In my case, setting url: '' in ajax settings would result in a status code 0 in ie8.. It seems ie just doesn't tolerate such a setting.
For me, the problem was caused by the hosting company (Godaddy) treating POST operations which had substantial response data (anything more than tens of kilobytes) as some sort of security threat. If more than 6 of these occurred in one minute, the host refused to execute the PHP code that responded to the POST request during the next minute. I'm not entirely sure what the host did instead, but I did see, with tcpdump, a TCP reset packet coming as the response to a POST request from the browser. This caused the http status code returned in a jqXHR object to be 0.
Changing the operations from POST to GET fixed the problem. It's not clear why Godaddy impose this limit, but changing the code was easier than changing the host.
I think I know what may cause this error.
In google chrome there is an in-built feature to prevent ddos attacks for google chrome extensions.
When ajax requests continuously return 500+ status errors, it starts to throttle the requests.
Hence it is possible to receive status 0 on following requests.
In an attempt to win the prize for most dumbest reason for the problem described.
Forgetting to call
xmlhttp.send(); //yes, you need this pivotal line!
Yes, I was still getting status returns of zero from the 'open' call.
In my case, I was getting this but only on Safari Mobile. The problem is that I was using the full URL (http://example.com/whatever.php) instead of the relative one (whatever.php). This doesn't make any sense though, it can't be a XSS issue because my site is hosted at http://example.com. I guess Safari looks at the http part and automatically flags it as an insecure request without inspecting the rest of the URL.
In my troubleshooting, I found this AJAX xmlhttpRequest.status == 0 could mean the client call had NOT reached the server yet, but failed due to issue on the client side. If the response was from server, then the status must be either those 1xx/2xx/3xx/4xx/5xx HTTP Response code. Henceforth, the troubleshooting shall focus on the CLIENT issue, and could be internet network connection down or one of those described by #Langdon above.
In my case, I was making a Firefox Add-on and forgot to add the permission for the url/domain I was trying to ajax, hope this saves someone a lot of time.
Observe the browser Console while making the request, if you are seeing "The Same Origin Policy disallows reading the remote resource at http ajax..... reason: cors header ‘access-control-allow-origin’ missing" then you need to add "Access-Control-Allow-Origin" in response header. exa: in java you can set this like response.setHeader("Access-Control-Allow-Origin", "*") where response is HttpServletResponse.
