I run my laravel app #localhost.
```php artisan serve --host=localhostIP```
On top I run an Andoid app with the same base URL.
Could anyone tell me how can I debug incoming API´s calls
like if BASEURL/users is called?
Furthermore, how can I log the happening events in the console
I am developing API's with laravel too, i do it this way:
composer require laravel/homestead to have it all in a vm 😉 see https://laravel.com/docs/master/homestead for more information, i use the "per project" installation
Download postman to have the best tool for sending querys to your api and to test your api quick -> https://www.getpostman.com (i use it free)
configure and run your homestead (it's not that complicated).
your homestead is fit with php and xdebug enabled
i am using phpStorm and have my vagrant setup as deployment target
"listen to debug" with phpstorm
to your GET requests, add a queryparam XDEBUG_SESSION_START=PHPSTORM
i can debug my api now 😉
i also wrote https://logcrawler.de to receive the log informations of all my api's and all my server 🤩
I hope, i could help you a little bit
This is my way, but I think it's not good!
Create router api in config/web, Eg:
router/api: Route::post('/check_api', [CheckController::class, 'testFunc'])->name('api.check_api');
web/api: Route::post('test/check_api', [CheckController::class, 'testFunc'])->name('test.check_api');
Create a post by form or ajax in one resource/view like index
Go to page, and debug with phpstorm
You can use logging feature of Laravel. Apply Logs on entry point of application to test whether API url is hitting or not.
use postman

it's an excellent thing very much usefull
I am trying to implement an API that should run smoothly on a server created. Here is the code for the custom API (I didn't make it). The file name for that custom API is pings.rb. Then I created a server.rb, which looks like:
require 'sinatra'
get '/clear_data' do
status 200
end
When I run server.rb, it successfully runs the server, but when I type ruby pings.rb, it returns some errors in the API.
What would be a possible error in my server, which made the API not run smoothly?
Your error message says a post should return a code of 200 and it's not, however the route you've defined is a get request. Try:
post '/clear_data' do
status 200
end
My Rails application regularly polls partners' ICS files and sometimes it fails for no reason whatsoever. When I do:
curl https://www.airbnb.es/calendar/ical/234892374.ics?s=23412342323
(params #'s faked here)
I get output matching the content of the ICS file. Just opening it in the browser works fine as well.
When I use:
Net::HTTP.get(URI(a.ics_link))
I get a "503 Service Temporarily Unavailable" response. I also tried the same with OpenURI with similar results.
Why is it that the server is treating requests from curl or a browser differently?
Is there some way to get Ruby to get around this?
It's an https issue... not sure why, but switch your url in Ruby to https and it should work.
I use the following code to pass data into a website:
require "net/http"
params = {"message"=>"some message", "to"=>"someone"}
Net::HTTP.post_form(URI.parse("http://example.com/m/send"),params)
When I inspect the web page, the form action is http://example.com/m/send and I can post the data using the site itself without any problem.
I keep getting HTTP 404 and my data is not passed to the database.
When I request the page with GET method, then I get HTTP 405, which is an unauthorized request error. This guarantees that the page exists.
Since the url is valid, what would prevent the data being posted? And how can I fix that?
I could not solve the question using Net/HTTP library solely; however, Mechanize gem as Tin Man suggested in the comments solves the problem and successfully posts the data into the server.
It is also more flexible and easier in terms of following redirection. Hence, if anyone runs into this problem like I did, I recommend them using the Mechanize gem.
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.
