Hey Everyone, I am trying to setup wiremock with my emulator to capture and modify(similar to what mitmproxy does) http and https request for android native app. 1. I have installed the certificate in emulator. 2. I want to only intercept 2-3 any call (there are 100s of different call to different host). So basically want to whitelist every other call except the ones I wan to put stub for. 
HashMap<ExecutionDataKeys, Object> executionStates = new HashMap<>();
WireMockServer wireMockServer = new WireMockServer(
        new WireMockConfiguration().port(8080)
                .notifier(new Slf4jNotifier(true))
);
wireMockServer.start();
ArrayList<String> hostNames = new ArrayList<>(
        Arrays.asList(
                "<https://host1.com>",
                "<https://host2.com>",
        ));

hostNames.forEach(host->{
    wireMockServer.stubFor(any(urlMatching(host+".*"))
            .atPriority(10)
            .willReturn(aResponse().proxiedFrom(host)));
});
I have also set proxy in emulator to localhost:8080. But it seems whitlisting is not working. all of my request are getting blocked. P.S. I am trying to use appium along with wiremock to test state changes in application [10:53 PM] I have already waster 3-4 days on this, and feeling kind exausted in this. [10:53 PM] Please advice

urlMatching(host+".*")
won't work - it only matches on path
You'll need a separate WireMock to pretend to be each remote host
You could try this: 
List<String> hostNames = Arrays.asList(
    "<https://example.com>",
    "<https://host2.com>"
);

int i = 0;
for (String host : hostNames) {
    WireMockServer wireMockServer = new WireMockServer(
            new WireMockConfiguration().port(8080 + i)
                    .notifier(new Slf4jNotifier(true))
    );
    wireMockServer.start();
    wireMockServer.stubFor(any(urlMatching(".*"))
            .atPriority(10)
            .willReturn(aResponse().proxiedFrom(host)));
    i++;
}
Or are you trying to run WireMock as a browser proxy? If so you just run one instance of WireMock, as so: 
WireMockServer wireMockServer = new WireMockServer(
    wireMockConfig()
        .enableBrowserProxying(true)
        .port(8080)
        .notifier(new Slf4jNotifier(true))
);
wireMockServer.start();
When you 
enableBrowserProxying(true)
you don't need to create the low priority 
any
stub at all, WireMock will proxy unless told otherwise.
However, you will need to set 
<http://localhost:8080>
as your proxy in your emulator.
You can then setup stubs for particular hosts by matching on the host header: 
wireMockServer.stubFor(
    get(urlPathEqualTo("/foo"))
        .withHeader("Host", equalTo("<http://host2.com|host2.com>"))
        .willReturn(aResponse().withBody("replacement for <https://host2.com/foo>"))
);

I beleive below does the same as adding for all host. 
hostNames.forEach(host->{
    wireMockServer.stubFor(any(urlMatching(host+".*"))
            .atPriority(10)
            .willReturn(aResponse().proxiedFrom(host)));
});

No, it doesn't
I wrote the browser proxying feature for WireMock

I suspect you want the browser proxy above: https://wiremock-community.slack.com/archives/C04HHJ7F20G/p1676485044520229?thread_ts=1676481954.237299&amp;cid=C04HHJ7F20G
It's documented here: https://wiremock.org/docs/proxying/ under "Running as a browser proxy"

I am not doing browser proxy.
I am doing proxy for my android emulator
which has react native app
all of the call are being made by this app
r

Rob Elliot

02/15/2023, 7:09 PM
For "browser proxy" read "forward proxy"
It's the same principle - your app calls the real hostname, but it is served via WireMock as a proxy
Your other options are: • A WireMock per remote API, and change the hostname your client uses to the WireMock hostname. Set up the 
any
stub for 
/.*
to proxy to the real service. • A single WireMock and set up multiple 
any
stubs, one for each remote API, matching on the 
Host
header - but this will require you to override the 
Host
header when making the request, which your HTTP client may make quite difficult. I wouldn't recommend the second one.

can you provide paid support for this problem. Would love to buy a coffee
i believe it would hardly take 10-15 mins of ur time

Hey I contacted you directly to see if I can help further - waiting for your answer.
Hi, I've been thinking about this further - I suggest you: 1. Download WireMock standalone from https://repo1.maven.org/maven2/com/github/tomakehurst/wiremock-jre8-standalone/2.35.0/wiremock-jre8-standalone-2.35.0.jar 2. Run it as so: 
java -jar wiremock-jre8-standalone-2.35.0.jar --enable-browser-proxying --port 8080 --verbose
. Then WireMock will be running before the emulator starts. 3. Start the emulator and configure the proxy 4. Try opening a browser inside the emulator and see if you can access https://example.com from it, with WireMock seeing the traffic. At least the browser should give you more feedback about what is wrong - whether it is a certificate problem or something else.

That's odd... it looks like the emulator is actually making the request to WireMock instead of making the request to example.com with WireMock as the proxy! Can you see the traffic in your console where you're running WireMock?
I'd like to see what the request looked like from WireMock's point of view, see if I can reproduce it. Could you post your proxy settings, too?

I don't understand where WireMock is getting 192.168.1.38 from. You are requesting https://example.com proxied by http://127.0.0.1:8080 , which is WireMock. The request is being intercepted by WireMock. However, instead of calling example.com WireMock is... calling 192.168.1.38 ?!
Do you have any stubs configured? Visit http://localhost:8080/__admin/mappings and tell me what it says
