Whenever I try to call Magento's rest resources via PHP, I get an HTTP 500 Internal Server Error. My link is, in accordance to Magento's REST API, http://mymagento.com/api/rest/products.
Everything is set up properly and whenever I try to access it via the browser, the response is a page with the XML data I want. Same thing goes for the RESTClient plugin for Firefox.
I also get the internal server error whenever I try to do an authorised request as a customer.
Does anyone know why this is happening? I ran out of ideas an hour ago or so.
If you just got that problem (only) then,
500 errors in the HTTP cycle
Any client (e.g. your Web browser or our CheckUpDown robot) goes through the following cycle when it communicates with the Web server:
Obtain an IP address from the IP name of the site (the site URL
without the leading 'http://'). This lookup (conversion of IP name to
IP address) is provided by domain name servers (DNSs).
Open an IP socket connection to that IP address.
Write an HTTP data stream through that socket.
Receive an HTTP data stream back from the Web server in response.
This data stream contains status codes whose values are determined by
the HTTP protocol. Parse this data stream for status codes and other
useful information.
This error occurs in the final step above when the client receives an HTTP status code that it recognises as '500'. (Last updated: March 2012).
Fixing 500 errors - general
This error can only be resolved by fixes to the Web server software. It is not a client-side problem. It is up to the operators of the Web server site to locate and analyse the logs which should give further information about the error.

I'm developing an app based on the Docusign C# Quickstart.
Its working fine on my development PC (Win 11) in Visual Studio 2019 using IIS Express.
However, when I publish it to IIS (v10) on my development PC it runs and I can authenticate with Docusign just fine (once I got the proper redirect URI registered: https://localhost/ds/callback) but the step that actually sends the envelope is returning the following error in the browser:
This page isn't working right now.
Local host can't handle this request
http error 500
Any help is appreciated. I logged a support ticket with Docusign, but still waiting for a response.
Quickstart is just an app to show you how to use DocuSign APIs.
The redirect after signing is back to localhost, and your app, once ready to be deployed to server, has to be set with a proper URL, at which point you'll need to update the redirect URI to the one based on your server.
The 500 error is coming from your app, not from DocuSign. You need to figure out why your app cannot handle the URL that is set for redirect after signing by DocuSign.
The base API address demo.docusign.net/restapi is used to reach the development/ test platform. The na4.docusign.net/restapi address is one of DocuSign's (many) production platforms.
Remember that, once you have passed the Go-Live process, you have two Client IDs (integration keys) one for the test platform, one for all of the production platforms. Each has its own settings.

The error
This page isn't working right now.
Local host can't handle this request http error 500
Is from IIS. Use IIS logging to see the URL request that is coming in that can't be handled.
To see if it is the redirect from the initial OAuth Authorization Code grant URL, examine the initial URL redirect to account.docusign.com (prod URL).
The redirect contained as a query parameter in the initial OAuth redirect must:
Be correct for your instance of IIS.
Be allowed by your setting for the client ID (integration key) in DocuSign
1, Be properly handled by your IIS and its app.
Is it possible to check Http status code in Apache configuration as %{REQUEST_STATUS} for instance?
There is no such thing as a "request status", and no way for a server to interact with a browser in the middle of serving an error message.
HTTP is not an interactive protocol; the browser sends a request, the server sends a response, and that's it. So if the browser sends a request, and the application crashes, the server can send a response with 500 and the error details, or a response with 401 requesting the user to log in. Either way, that's the end of the conversation.
When it receives a 401 response, the browser can't say "here's the login details, carry on with the current request", it has to make a new request. It can make an identical request, which might reproduce the error message; but the original error message is gone.
If the requirement is to show a different amount of detail to different users, you need some notion of optional authentication, so that the server can decide immediately whether to include the error details or not, without an extra round-trip to the browser. I would suggest either:
Have a list of IP addresses which the application can check against; if the IP address of the request is in the list, include the error details.
Have a custom login system where you can authenticate and set a "session cookie" in the browser. If the user has an active session cookie, include the error details.
I have received some weird request URL in my TOMCAT access logs. which is
as follows:-
\x16\x03\x01\x01\"\x01" 200 40788
as clearly seen from above log, the server has given 200(success) response to the client(the one who is accessing above URL from our server).
I am really concerned whether the hacker is trying to post some malicious data on the server?
above request is in which format? is it in hexadecimal?
how should I convert above request URL to text format so that I will get to know
which resource he is trying to access or on which URL he is trying to post?
I have a web server that is currently running my asp.net mvc website. I am making a connection to an external website that sends a request back to the server via a specific URL and attaches the information sent as a query string.
I have no idea if this query string being sent is in the correct format but I do know that the action result function is being called. I need to see what requests are being sent to the server so that I can see the format in which the request was sent.
I know how to view the currently executing requests using the request monitor, but this is not enough since you can miss the request if it happens to fast.
Is it possible to view a history of requests that have occurred on the server? So that I may find the one that I need after the request has occurred.
Whenever I try to add the following endpoint, "http://ws.cdyne.com/phoneverify/phoneverify.asmx", during the Managed API setup process and press the Test button I get an error on the server. ERROR - APIProviderHostObject Error occurred while connecting to backend : "stackOverflow preventing me from showing this link", reason: Connect to ws.cdyne.com:80 timed out
When I try this exact same process on a machine outside of our proxy it works fine. I have gone into the axis2.xml file and added proxy information and even went as far as installing cntlm and setting the proxy to localhost - same error.
I can browse to the above link just fine on this machine.
My environment is Windows 10.
I assume you talk about clicking the Test button when providing Backend Endpoint in API publisher.
The way that Test button works at the moment (as far as I understand) is that it invokes HTTP HEAD method on the endpoint provided (because according to RFC 2616, "This method is often used for testing hypertext links for validity, accessibility, and recent modification.")
Then it checks response. If response is valid or 405 (method not allowed), then the URL is marked as Valid.
Thus sometimes, if backend is not properly following RFC, you might get otherwise working URLs declared as Invalid during the test because of that improper HEAD response evaluation. Obviously, this is just a check for your convenience and you can ignore the check if you know the endpoint works for the methods and resources you need it to work.
So my advice would be to try ignoring the Test and just finishing setting up and publishing the API.
P.S. I am checking it on WSO2 API Cloud but behavior is identical to downloadable API Manager.
