If I send a large POST request using OkHttp, but the server responds quickly with an error (e.g. permission denied) I get a
java.net.SocketException: Broken pipe (Write failed)( status = 272 )
exception.
Command line tools like curl seem to handle this case just fine and are able to return the HTTP Response instead of aborting because the write failed.
Is there a way to configure OkHttp to do the same?

I have used the websocket open connection sampler request in my project.
URL: wss://sip-qa.forestreettelco.com:11443
while executing the jmeter script getting the Response message:"http upgrade failed with status code 400"
Please help me.enter image description here
As per HTTP Status Code 400 description
The HyperText Transfer Protocol (HTTP) 400 Bad Request response status code indicates that the server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).
So my expectation is that you're sending the wrong request which doesn't match what your server expects. As it is not publicly available I cannot come up with the proper configuration, however I believe you should start with normal HTTP Request sampler and add the following Headers to the request:
Connection: Upgrade
Upgrade: websocket
Whatever other headers which real browser sends like Sec-WebSocket-Protocol, Sec-WebSocket-Version, Sec-WebSocket-Key, etc.
The headers can be added using HTTP Header Manager
You can capture browser traffic using built-in browser developer tools or an external sniffer tool like Wireshark.
Once you will be sending the same sequence of the same requests you should get the same responses as for the real browser.
I have given two url in csv file and trying to load that in jmeter. I am getting 503 response code.
As per HTTP 503 status code description
The HyperText Transfer Protocol (HTTP) 503 Service Unavailable server error response code indicates that the server is not ready to handle the request.
Common causes are a server that is down for maintenance or that is overloaded. This response should be used for temporary conditions and the Retry-After HTTP header should, if possible, contain the estimated time for the recovery of the service.
Note: together with this response, a user-friendly page explaining the problem should be sent.
Caching-related headers that are sent along with this response should be taken care of, as a 503 status is often a temporary condition and responses shouldn't usually be cached.
So I can think of at least 3 possible issues:
Your server is really overloaded, you can try checking Response Data tab of the View Results Tree listener - if you're lucky - you will the the aforementioned "user-friendly page explaining the problem"
Your request is malformed and server is sending 503 response instead of 4xx which indicates client-side error. Double check what URL(s) you're trying to open by looking into Request tab of the View Results Tree listener and try to open it in the browser. If you're building the URL from parts (i.e. host, port, protocol, query string, etc.) - you might want to check if the values are correctly read from the CSV file using Debug Sampler
I fail to see HTTP Header Manager in your Test Plan, some servers check the client Headers, for example User-Agent or Accept and may report an error if the required header is missing (i.e. indicating that the browser is not supported)
I'm developing an application which acts as an Http-Proxy for serving files from an external resource. It actually downloads the file from the external resource, checks for viruses and if the file is not infected, returns the file to the client.
My problem is, in case of the file is infected, what HTTP Status code my service should return? I suppose that any type of 4xx error codes is not appropriate for that situation because this class of code is intended for Client errors.
Is a 502 (Bad Gateway) error more appropriate?
Is there any kind of Standard that covers this situation?
I think you are right maestromarko : 502 Bad Gateway. Read the specifications here:
The 502 (Bad Gateway) status code indicates that the server, while
acting as a gateway or proxy, received an invalid response from an
inbound server it accessed while attempting to fulfill the request.
Your proxy is acting as a Gateway and he received what it conciders is invalid as there are virus in it.
It is not a 4xx class error, because whatever the client changes in the request, the result will still be an error.

Http response codes are only meant to handle http specific conditions so I don't think there is a correct answer as such. But some possibilities...
204 - "The server successfully processed the request and is not returning any content"
403 - "The request was valid, but the server is refusing action"

I have read and tried the solutions shared in the previous posts for this error but nothing helped me to fix this. Kindly help.
I am making a HTTPS API call. A very simple call which accepts a 2 KB JSON message via POST method and sends a one word acknowledgement. It works perfectly fine in Postman tool. In JMeter, no. of threads (users) is kept as 25. It works perfectly fine one time with all 25 success response and at times getting few failure response as
Response code: Non HTTP response code: java.net.SocketException
Response message: Non HTTP response message: Unexpected end of file from server
No consistency at all. I have also tried with both enabling and disabling "use keepalive" checkbox. Both giving me all success one time ; few/all failure at another time with the above error. Please help. Thank you.
Below are the JMeter settings:
HTTP Header Manager : Content-Type - application/json
HTTPRequest sampler : protocol - HTTPS
Server Name or IP : project server name
Method : POST
PATH : The required path with https authentication details passed as parameters
IMPLEMENTATION : Set to JAVA (HTTPCLIENT4 was giving me “443 failed to respond” error)
Add header
Connection Keep-Alive
Both errors (Java implementation and Apache HTTPClient4 implementation), are essentially saying the same thing: The server closed the connection, without providing any response. I think there could be the following reasons:
Authentication problem. If server side checks authentication before processing a request (e.g. using Spring), it may be rejecting your request, it may be not bothering with any response if authentication is not considered correct.
Request Issue. Some less noticeable properties of the request you send via Jmeter are different from what you send in Postman. It could be some minor thing with formatting, or some headers server expects. Some of such inconsistencies can also cause Load Balancer (if you use one) to reject request before it's delivered to the server.
Certificate issues. Since you are using HTTPS, you need to make sure your certificate is setup correctly on JMeter side.
So I suggest:
Review server logs and see if your request makes it to the server. If yes, you might be able to see how it was rejected. If not, you need to trace back and see who rejected it (LB, authentication, etc)
Compare headers and body sent by JMeter vs Postman line to line (use TCPDump for example to obtain it).
I am developing both client and server. During development, I would the server to detect when the client appears to be buggy (send invalid data, omits mandatory parameter, etc, etc).
Is there a standard HTTP response code to indicate this? Or several, depending on the nature of the bug?
Or should I just use my own response code?
e.g 2001 I'm afraid I can't do that, Dave?
or 666 Mwuuuuuuhahhahahahahahahaha
HTTP 400 "Bad Request"
https://www.rfc-editor.org/rfc/rfc7231#section-6.5.1
The 400 (Bad Request) status code indicates that the server cannot or
will not process the request due to something that is perceived to be
a client error (e.g., malformed request syntax, invalid request
message framing, or deceptive request routing).
