I am using reactor netty httpClient to make my requests. Via reactor netty's httpClient you can specify a protocol to use for the request or specify more than one: You can then specify the HTTP2 protocol of type H2, H2C or specify to use HTTP1.1. Reactor netty also gives the possibility to configure all 3 protocols together:

HttpClient client =

HttpClient.create()

.protocol(HTTP1.1, H2C, H2 );

We are having several problems in our tests when configuring the HTTP1.1 protocol together with another HTTP2 protocol. Basically when HTTP1.1 is configured together with H2C or H2, reactor netty at the first request sends a request of type Connection: upgrade to understand what type of protocol the server supports in order to use the right protocol for the request. However, we noticed that wiremock does not handle Connection: Upgrade requests.

wireMockRule.stubFor(

post(urlEqualTo("/index.html")).

withRequestBody(equalTo("Wikipedia in\r\n"

+ "\r\n"

+ "chunks."))

.willReturn(aResponse()

.withStatus(200)

.withHeader("Content-Type", "text/html")

.withBody("it <b>works</b> !!"))

);

By placing a subFor of this type, we see that when the Connection: upgrade request arrives, it sees that the body is empty, so it breaks and closes the connection without actually managing the connection upgrade. We tried to introduce a subFor that manages the case in which a connection: upgrade arrives but the problem is that after having managed, wiremock closes the connection and therefore reactor netty is unable to continue the request. In particular we did something like:

wireMockRule.stubFor(

post(urlEqualTo("/index.html"))

.withHeader(String.valueOf(HttpHeaderNames.CONNECTION), containing("upgrade") )

.willReturn(aResponse()

.withStatus(200)

.withHeader(String.valueOf(HttpHeaderNames.CONNECTION), "upgrade")

.withHeader(String.valueOf(HttpHeaderNames.UPGRADE), "HTTP/2.0")

));

wireMockRule.stubFor(

post(urlEqualTo("/index.html")).

withRequestBody(equalTo("Wikipedia in\r\n"

+ "\r\n"

+ "chunks."))

.willReturn(aResponse()

.withStatus(200)

.withHeader("Content-Type", "text/html")

.withBody("it <b>works</b> !!"))

);

The problem, however, is that by matching the first subFor, it still immediately closes the connection. So reactor netty is not able to go and send data. If configured together H2C and H2 the problem does not arise as Connection:upgrade over http2 is not supported. If configured HTTP1.1 alone the problem does not arise. Do you have a solution to handle this issue?

@Muthukkumar Ponnusamy you can post your doubt here

Hello. What is the default priority of each stub if it's not defined? And which priority takes? 10 or 0?

Hello, is there a way export logs that lambda are producing?

Hello Can someone help me to make integer from string in a response? Like this:

"year": "{{now format='yyyy' type='NUMERIC'}}",
"month": "{{now format='M' type='NUMERIC'}}",
"day": "{{now format='d' type='NUMERIC'}}",
"hour": "{{now format='h' type='NUMERIC'}}",

But this doesn’t work. Main idea is that I generate components(year, month, day…) from date with formats and then I want to make it to integer types to decode it, because backend sends this fields in integer type. Or maybe someone can suggest another way to mock response like that?

Hello i’m running WireMock as a server (WireMockServer) and use the enableBrowserProxying=true, i would like to know how to return a stub response when the request is not matched. currently it’s always passing the request to the external url. Consuming application sends this request with stub server as forward proxy e.g. Request url https://www.sample.com/api/pattern proxy: stub-server-host:4000 Wiremock should return http 404 when the request pattern /api/pattern does not match with any stub mapping Is it correct that the following payload must be sent to the API { ... “proxyPassThrough”: false } What is the full request payload and wiremock rest api url for this?

Hi everyone, I have a GET request with one id and based on that id i need to return a specific body with an array of ids Is this possible to do with JSON template? without creating hundreds of fixed mappings?

Hi Team, We at are planning to implement WireMock Standalone jar (Running in docker) for Service Virtualization with AWS infrastructure (EKS cluster). Due to budget constraints, our organization is preferring to use opensource/free version of WireMock (standalone jar). It would be great if someone could guide us with the queries our DevSecOps team have for the implementation – Recommended resource request/limit for deployment in K8s using helm chart ?(Kindly provide the estimated volume for virtual environment which can support functional and performance testing on virtual services) Is HPA supported in k8s for WireMock? We have multiple projects/APIs to support with WireMock-virtual services. How can we run and manage the WireMock instances on multiple ports in containerized environment ? How much is the load/traffic can WireMock standalone jar supports in terms of transaction per second? Any special instructions which we need to follow while containerizing the WireMock-Docker approach?

Hi All,

I want to export all stub mappings and files to remote wiremock instance hosted on AWS . I am able to access remote EC2 windows instance from local . Everything works fine using both java api and Admin api conecting to remote instance . By manually copying files and mappings to remote wiremock directories it works fine but i would liek to push the files using java API as mentioend in the documentation but not able to do so . Attaching screenshot for Project Structure on local where wiremock client talks to remote instance ERROR: Exception in thread "main" java.lang.RuntimeException: \wiremock-stuff\mappings does not exist at com.github.tomakehurst.wiremock.common.AbstractFileSource.assertExistsAndIsDirectory(AbstractFileSource.java:143) at com.github.tomakehurst.wiremock.common.AbstractFileSource.listFilesRecursively(AbstractFileSource.java:77) at com.github.tomakehurst.wiremock.standalone.RemoteMappingsLoader.load(RemoteMappingsLoader.java:48) at com.github.tomakehurst.wiremock.client.WireMock.loadMappingsFrom(WireMock.java:869) at com.github.tomakehurst.wiremock.client.WireMock.loadMappingsFrom(WireMock.java:864) at Master.main(Master.java:57)

Hi Team, Need help in setting up dynamic delays using wiremock standalone jar. The value for delays are passed in query parameter of a post call. For example - http://localhost:8080/responsum?response=hl7_ack&delay_in_secs=3 then the api should have the delay of "3" seconds

Is it spam or it's yours stuff?

Hello, Can someone please help me with the dynamic port usage? I wrote a wiremock test using @WiremockTest annotation. Wiremock server is coming up on a default port. I am able to call my service from the test but I am not able to understand how do I modify the wiremock's dynamic port on the fly in the service, so that service makes the third party service call to wiremock instead of actual third party service. I am blocked on this. Request the team to help. P.S. - Intent is to run each wiremock test class with a separate wiremock server on dynamic port against the service.

Hello, I need some help. I want to delete all requests, which are not contains a metadata with a correct expression (jsonpath). I'm trying to call /requests/remove-by-metadata with the following body: { "matchesJsonPath": { "expression": "$.serviceName", "doesNotMatch": "myservice" } } But it's says in the logs: JSON path expression '$.serviceName' failed to match document 'null' because of error 'json can not be null' Anybody have some idea? Thanks in advance.

Hello, Is there any documentation available for using WireMock with Spring Boot 3? Currently, I'm getting the error NoClassDefFoundError: javax/servlet/DispatcherType. Thanks

Hello - I'm trying to simulate time out with withFixedDelay and I set the delay to 10000ms. But it only times out occasionally. And often times the delay is ignored and I get the response normally. How do I make sure, I'm timing it out? Thanks

How do I use something similar to --proxy-all but in wiremock cloud?

Hi, We have front end application that interact with back end api.. when i crawl through via front app will it record all the backend api calls via wiremock ?

Hello! Thanks for the amazing tool which really helps! I have a question about recordings file names. We store the recordings in git and it would be really nice to control the names of files. Would be really cool if new recording files going to have as much the same names as previous so they are overriding the old recording and we can easily check the changes in 3rd party API we are mocking. Is there any solution for that in Wiremock?

Hello All, do you know if my wiremock is hosted in a vm/contianer and while accessing/testing i can access it by using <ip>:<port>, is there a way if the ip and the port can be replaced by a domain such as instead of <ip>:<port>/endpoint, testing can be done by using xyz.com/endpoint. is this possible? CC: @Oleg Nenashev Regards,

Hi folks, just want to know is it possible to enable basic authnetication for all the stubs at one go or at wiremock instance level instead of individual stubs

Hello! I'm looking into the way how can I import the prerecorded scenario with several requests into the running Wiremock instance with Admin REST API. I need to import the whole folder with multiple recorded mock JSON files but here I can se how I can do that only with Java API? https://docs.wiremock.io/import-export/wiremock/ Is there a way to do that with pure REST API?

Hello, I am using testcontainers with wiremock, but I am getting the error: connect to localhost:8080 failed connection refused no further information. Please suggest some solution to this.

Hello! I am looking into a way of how to create a proxy server when a URL is not available using wiremock. We are using a third party SDK. It does not provides URls which I can mock. For other third party API I am creating the mock server using the following info. I need help on how I can create a proxy server when URL is not available

wiremock:
      proxies:
        - service-name: ABC
          port: 9091
          url: <https://abc.com>
          mappings-path: /wiremock/abc
          recording: false

Hello! I have a question regarding usage of Jackson views defined in Core PrivateView and PublicView specifically for persistence of stub mappings on filesystem. Is there a way to inject config so id and uuid are not persisted along with stubmapping on file system and leverage Views defined already. We are using wiremock in a shared environment where team will develop mocks locally and will push to a remote git rep, where they will be served over a remote wiremock instance. While doing this, noticed that wiremock persists ids/uuids locally and dont want collision of ids and hence looking for a way to have them as transient.

Hello Team, I want to use wiremock to intercept a production URL and do MITM and send back stubbed response without actually hitting production server. Is it possible? Please note I have already tried using

--proxy-all

but no luck

Hello All, Can any one please explain, how to add dynamic bearer token in the authorization section? I coud see basic authorization in place in the documentation, does the bearer token works same way? if it is similar to that, how it can be dynamic, with jsonpath? Regards, Prasenjit
