Hi, I'm facing a strange issue. I'm upgrading our project to Java 21, SpringBoot 3.5 and gradle 8.14. I have set to use last stable version of wiremock : org.wiremockwiremock standalone3.13.1 I have a class that extends StringValuePattern:

*import* com.fasterxml.jackson.annotation.JsonProperty;

*import* com.github.tomakehurst.wiremock.matching.MatchResult;

*import* com.github.tomakehurst.wiremock.matching.StringValuePattern;

import

*static* com.github.tomakehurst.wiremock.common.Strings._normalisedLevenshteinDistance_;

public

*class* EqualVinOutInAnyOrderPattern *extends* StringValuePattern {

*public* EqualVinOutInAnyOrderPattern(@JsonProperty("equalVinOutInAnyOrder") String expectedValue) {

*super*(expectedValue);

} @Override

*public* MatchResult match(String actual) {

return

*new* MatchResult() {

...

This class is now failing when the constructor calls the getName() When I debug I well see a

this.getClass().getDeclaredConstructors()[0].getParameterAnnotations()[0][0] instanceof JsonProperty

with the correct value, but the execution still goes to the throw Exception. Does anybody have the same issue or have an idea of what happens ?

Is there a way to remove a specific HTTP header from wire mock response?

Hello everyone. I use wiremock grpc extension with standalone wiremock instance. In .proto file I have something like

map<string, any>

. My response looks like

Copy code

"data": {
          "price": {
            "@type": "type.googleapis.com/google.protobuf.DoubleValue",
            "value": 0.00873388535031847
          }
        },
        "user": {
          "userId": "5235435"
        }

But wiremock throw an exception:

Copy code

wiremock.com.google.protobuf.InvalidProtocolBufferException: Cannot resolve type: type.googleapis.com/google.protobuf.DoubleValue	at wiremock.com.google.protobuf.util.JsonFormat$ParserImpl.mergeAny(JsonFormat.java:1511)	at wiremock.com.google.protobuf.util.JsonFormat$ParserImpl.access$2000(JsonFormat.java:1276)	at wiremock.com.google.protobuf.util.JsonFormat$ParserImpl$1.merge(JsonFormat.java:1343)	at wiremock.com.google.protobuf.util.JsonFormat$ParserImpl.merge(JsonFormat.java:1432)	at wiremock.com.google.protobuf.util.JsonFormat$ParserImpl.parseFieldValue(JsonFormat.java:1995)

Any clue what's wrong?

Hi, does anyone know how to enable logging for grpc requests? I've already enabled grpc extensions and also turned on --verbose, but still cannot see any grpc requests in the log.

Hi everyone, nice to join you. Could you help whether wiremock-grpc-extension supports bidirectional streaming with multiple responses?

Hi everyone, am trying to create a mock for application/xml request. I need to initiate callback on request. Also, need to copy the parameters from original request to callback request. what handlers do I need to use?. am using a wiremock-standalone-3.13.1.jar version of wiremock. #C03N1E6HFPY

One more question.. in "serveEventListeners" can I only use body? can't bodyfilename not supported in this version of wiremock ? I wanted to use for callback requests.. #C03N1E6HFPY

Hi! I want to create 2 stubs for the same endpoint to validate service's behavior. So I decided to filter the incoming requests by a form param:

Copy code

wireMock.stubFor(<http://WireMock.post|WireMock.post>("/convert")
        .withFormParam("amount", WireMock.equalTo("10.50"))
        .willReturn(responseDefinition1));

    wireMock.stubFor(<http://WireMock.post|WireMock.post>("/convert")
        .withFormParam("amount", WireMock.equalTo("12.50"))
        .willReturn(responseDefinition2));

However, the

amount

can easily be

10.5

12.5

due to inconsistent precision, and that doesn't work -

10.50

and

10.5

are different strings. I solved this by extending

StringValuePattern

and overriding it's matcher which now converts both values to

BigDecimal

and compares them with

compareTo

. My concern is that I perhaps overengineered this and missed a simpler solution. Is there one to compare decimal values in form params? I only found a similar issue with JSON bodies: https://github.com/wiremock/wiremock/pull/2588

Hello, I’m using the latest version of WireMock-GO and trying to configure a response with "WithJSONBody". However, I’m having trouble passing a JSONPath helper inside the body template. Is there a way to include JSONPath helpers in a WithJSONBody response or other method? Here’s the error I’m getting: "build stub request error: json: unsupported type: func(string, interface {}) (string, error)" I suspect this happens because WithJSONBody is marshalling the template as JSON and treats the helpers as unsupported types. What is the recommended approach to return a JSON body that contains WireMock helpers like {{jsonPath ...}}?

Unable to disable gzip in WireMock Docker – container exits immediately when using

--no-gzip

Description:

I'm running WireMock via Docker and trying to disable gzip compression because my client needs uncompressed responses.

I've tried:

Setting the environment variable:

docker run -d \ --name wiremock \ -p 8080:8080 \ -e WIREMOCK_NO_GZIP=true \ wiremock/wiremock:latest …but the responses still contain

Content-Encoding: gzip

. 2. Passing

--no-gzip

as a CLI flag: docker run --rm -it \ -p 8083:8080 \ wiremock/wiremock:3.9.1 \ --verbose --no-gzip …but the container immediately exits with: Exception in thread "main" java.util.MissingResourceException thrown from the UncaughtExceptionHandler in thread "main" 1. 3. Using older versions (e.g.,

2.35.0

) with

--no-gzip

results in:

Copy code

pgsql

Copy code

joptsimple.UnrecognizedOptionException: no-gzip is not a recognized option

W*hat I’ve confirmed:* • Docker image pulls and runs fine without

--no-gzip

. • Problem only occurs when trying to disable gzip. • Removing containers and images before retrying doesn’t fix it. Questions for the community: • What is the correct way to disable gzip in the latest WireMock Docker image? • Is

--no-gzip

supported in the official Docker images, and if so, from which version? • Could the

MissingResourceException

be a packaging issue in recent releases?

Hey everyone, It is possible to use WireMock in Cluster mode? I tried this and configured multiple replicas in my Kubernetes Cluster. Besides this did I bound the

/mappings

and

/files

folder with a shared storage to each other. This work very well, but the other instances did not refresh the instance caches with the stored mappings. Is there a configuration/setting that could help in this case?

Hello Team ! Is it possible to generate a stub server from an OpenAPI specification using the WireMock standalone JAR? I noticed that this option is available in WireMock Cloud, but I couldn’t find a similar feature in the standalone JAR.

Hello! I'm having what I think is a silly issue, but I can't figure it out. I'm seeing errors from my local app saying

java.io.FileNotFoundException: /home/wiremock/./__files/responses

which makes sense because it seems like that path is incorrect. The problem is I can't figure out how to correct it. I've defined wiremock in my docker compose (defined at

.docker/compose.yml

as follows:

Copy code

wiremock:
    image: wiremock/wiremock:3.12.1
    container_name: wiremock
    ports:
      - "3000:8080"
    volumes:
      - ../wire-mock:/home/wiremock
    entrypoint: ["/docker-entrypoint.sh", "--global-response-templating", "--disable-gzip", "--verbose"]

my wiremock directory is a top level directory at

wire-mock

in the project Any help would be greatly appreciated. thanks y'all

Hi there! I have some troubles with wiremock, for example, when it returns a 500 error. but the response to the embedded answer is returned correctly. And I am a complete newbie in using this tool. Can you please tell me how and where the application logs are saved?

Hi, If I change anything in API response from mappings folder and invoking the API in Postman without restarting the wiremock standalone server, My latest change in response is not reflected. I could see the response changes only after the wiremok standalone server re-start. I wanted to know is there any way to reflect my changes without restarting the wiremock standalone server and it should be available with hot reloading. I could observe the hot reloading can be achieved with below ways: 1. In mapping folder, responses should be mapped with filename and respective response contents should be placed in __files folder. So if i change the response content in __files folder and invoking the API in postman, it is reflecting immediately. 2. Once i have done the changes in response from mapping folder, if i hit the below API, and invoke the API for which i changed the response from Postman, I am getting the latest response. POST:<Local or Server endpoint>/__admin/mappings/reset Apart from these 2 approaches, I wanted to understand, is there any way, I am changing the response in mapping folder and invoking the same in Postman, i need to get the response with my latest changes. Kindly advise.

Hello i have trouble in "absent" field. to check if

exist

field inside the

auth

object but when i pass the below pattern in mapping then it should point to different file but it is not doing - for both true and false it is going to same file, that is because it always maps to the same mapping irrespective i give

true

false

im using gradel deps --> implementation "com.github.tomakehurstwiremock jre8 standalone2.35.1

Copy code

"bodyPatterns": [
  {
    "matchesJsonPath": {
      "expression": "$.auth.exist",
        "absent": "false"
    }
  }

Hi! Is there a way in WireMock to record only the last request/response for the same method and URL - so each new matching request overwrites the previous recording? Right now I either get all duplicates or only the first one; I’d like the opposite: keep only the latest. Many thanks!

Hello there, getting below error whiling invoking wiremock endpoint(JSON stub deployed on different service) from a spring framework service A- `springframework.web.client.HttpClientErrorException$BadRequest: 400 Bad Request: "h1Bad Message 400/h1 prereason: Bad Request/pre".

Copy code

Service A utilises  org.springframework.http to call APIs.

It is failing at the line of toEntity()-

.retrieve()`

.toEntity(String.class);

Other services like B uses apache camel(routes), from there when it is invoked it is working. Just wanted to understand is this any mock related issue or it do not support http of spring.

Hello everyone! I am very new to WireMock and I have an issue when hitting the endpoint /_admin/requests/reset, a GET returns 400 which makes sense , but a POST returns 404 error. The request journal is enabled and i get a correct response when running GET to /__admin/requests, what am I missing here? Is the endpoint unavailable? Because I've seen that it's deprecated_

Hello everybody! That's the question. We use Wiremock JSON to mock in vendor responses in our tests. Often, suppliers may send different responses to the same request. To do this, we use scenarios to get the right response at the right time. Previously, we implemented it in such a way that wiremock was raised for each test. Consequently, the scenarios were not interrupted in any way. Now we plan to raise 1 wiremock for multithreaded tests (20+ units). What will happen to the scenarios? Will they be able to run parallel to each other?

Hi team! I am working on setting up a wiremock proxy service that my team can use to mock responses from external apis. I am hitting an issue where a proxied response that is being forwarded to the actual service is returning a 403 error. When hitting the external api directly I can connect. Is there something specific I need to do in the proxy mapping to have the authorization headers from the original request forwarded through to the real service? Currently I just have the proxy mapping for any request that hits a specific urlPath.

Hi everyone, I’m working on a WireMock Mapping and would be super grateful for some help. The WireMock receives a Request with a JWT as query parameter

code

. I use

serveEventListeners

to trigger a call. This call needs to extract the

sub

claim from the JWT and include it as

user_id

to body. I tried it with the jwt plugin like this

{{jwt path='sub' token=originalRequest.query.code}}

but it generated a new jwt, what is not really what I need. Is there any way to only extract that claim from the token?

Hi everyone, I am running wiremock in playback mode where I use the data ( mappings and __files ) which I recorded by running wiremock in recording mode. When my wiremock instance is running in playback mode with recorded data I am noticing that after sometime my wiremock instance ( pod ) throws Java OOM exception. I tried increasing the memory but it only delays the outcome but doesn't stop it. Here are some settings ( image: wiremock/wiremock:3.3.1, JAVA_TOOL_OPTIONS: "-XX:+UseContainerSupport -Xms1g -Xmx8g", WIREMOCK_DISABLE_REQUEST_JOURNAL: "true" etc etc. ). Any idea what I may be missing or how to fix this issue of Java OOM?
