Is it possible to intercept the request going through Charles and immediately return 500 error code without sending this request to the server?
Can't find any information on this. All resources suggest to wait for the response and then change HTTP response code to 500.
I assume you have already tried adding a rewrite rule to make the request to be returned with the 500 status. Have you tried combining this with a map local, to an empty file on your disk, for instance? It may work.
If this doesn't work too, I think I would do a Map Remote to another path on my localhost (for instance: http://localhost:8081/exected-response-500) and make that URL to return the 500 status error (in my case I would use a basic Spring Boot app to achieve this).

When I start a server with
nghttpd --no-tls -v 8444
And in another terminal I send a request
nghttp -v -y http://127.0.0.1:8444
I see that the server saw my request and responded with 404. Is it possible to configure to respond differently based on the request? (I 'd like to implement some basic logic, different return codes based on request method, path) Can you show me an example for that?
Lets say for GET request with /dog path return 200, and to post request return 404
I don't think this is possible. Nghttpd is a simple webserver to demonstrate the nghttp library and also useful for debugging HTTP/2, but it is not intended as a fully featured web server.
As an aside, I would also question whether a POST should return 404 to a valid path. 404 is "Not Found" which is not right - the resource is found. Most web servers would return the same as a GET request for such a request (as does nghttpd).
I have seen people using the HTTP code 500 as a generic error code for all kind of error cases (server errors, http errors, code exceptions, expected record not found in DB, time-out exceptions etc). However I have also read and heard that this code 500 should only be used in case of errors originating from the application server (JBoss in my case), and NOT application itself i.e. not for code-exceptions or invalid passwords or DB-record-not-found cases. So, when should we return HTTP Status Code 500 from a REST service method?
As described in the HTTP spec:
The 5xx (Server Error) class of status code indicates that the server is aware that it has erred or is incapable of performing the requested method. Except when responding to a HEAD request, the server SHOULD send a representation containing an explanation of the error situation, and whether it is a temporary or permanent condition. A user agent SHOULD display any included representation to the user. These response codes are applicable to any request method.

Note that from the protocol point of view, it doesn't matter whether it's the application server or something running inside the application server.
I have just installed openchain (http://openchain.org)
I can check it on http://nossl.wallet.openchain.org/ but I would like to check API using Postman Rest client tool on my PC.
I'm using postman rest client and I have tried URI many times but response is empty : https://docs.openchain.org/en/latest/api/method-calls.html
Please give some advises, thanks in advance !
You should want it to look like something like this picture. Check your headers also, when I use the URL https://www.openchain.org/endpoint/query/recordversion?key=FFFF I get nothing and then when I check the headers I see there is a 404 status which means I was able to communicate with the server but it couldn't find my key. Which makes sense since I am just passing a random key. So see if you are getting a 404 error in your headers and if so then make sure your key is correct.
Simply souncloud servers responds with 502 Bad Gateway error on a /playlists call to API with client_id and user_id parameters. Issue regards a specific user, so maybe something it's messed up on server or on profile.. but how can I resolve?! There's no recovery procedure or similar to try things works again?
I ran into this issue myself and believe I have found the root cause. After trying the playlists query in browser & curl I was able to get the valid data response (JSON).
Turns out Soundcloud includes all the tracks information of each playlist! I have the max (500) tracks in some playlists so the response payload size must be the issue. It must also be why we get an occasional timeout response.
I will see what I can do about limiting the data size in the response and may try other libraries (I'm using soundcloud-ruby.)
I am using PostMan as a REST client to test this API method Cisco ACL Analysis API. specifically POST /acl/trace or getAClTracksStd (first go to Policy Analysis)
Here is my PostMan HTTP test call
Does anyone who is familiar with PostMan understand why I am getting this "Request method 'GET' is not supported" error from the server? I am making a POST HTTP request, not GET.(Selected from Drop down menu) It make more sense for me to get a input invalid parameter error or something.
Just to show that the endpoint url works, heres a HTTP test request that works
(same link, host->host API -> GET /host/{startIndex}/{recordsToReturn}
There's two issues that I'm seeing with your REST call. First, the error you're seeing is because the call needs to be preceded by "https://". Second, remove the interface IDs parameter and values. You should get a response with data after making these changes.
Your json looks erronuous (comma after the destIp) - and the server probably always responds with a default confusing error message in this case. (Postman is very well tested and it sends POST).
