MockServer enables easy mocking of any system you integrate with via HTTP or HTTPS with clients written in Java, JavaScript and Ruby. MockServer also includes a proxy that introspects all proxied traffic including encrypted SSL traffic and supports Port Forwarding, Web Proxying (i.e. HTTP proxy), HTTPS Tunneling Proxying (using HTTP CONNECT) and SOCKS Proxying (i.e. dynamic port forwarding).

Error in deserialization of JSON #451

Closed IgorMaksymov closed 6 years ago

IgorMaksymov commented 6 years ago

i'm trying to send application/x-www-form-urlencoded request with body to:email@email.com

this is the test code: new MockServerClient("localhost", 1080) .when(request("/messages") .withMethod("POST") .withQueryStringParameter(Parameter.param("to","email@email.com")) ) .respond(response().withStatusCode(200)); And when this code is executed, i have this exception: IllegalArgumentException: Exception while parsing [{ "httpRequest" : { "method" : "POST", "path" : "/messages", "queryStringParameters" : { "to" : [ "email@email.com" ] } }, "httpResponse" : { "statusCode" : 200 }, "times" : { "remainingTimes" : 0, "unlimited" : true }, "timeToLive" : { "unlimited" : true } }] for Expectation

com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance ofjava.lang.Stringout of FIELD_NAME token at [Source: (String)"{ "httpRequest" : { "method" : "POST", "path" : "/messages", "queryStringParameters" : { "to" : [ "email@email.com" ] } }, "httpResponse" : { "statusCode" : 200 }, "times" : { "remainingTimes" : 0, "unlimited" : true }, "timeToLive" : { "unlimited" : true } }"

How can i bypass or fix this?

CarlosLoboZamarro commented 6 years ago

I have the same problem.

Any ideas to fix this error?

CarlosLoboZamarro commented 6 years ago

Hi @IgorMaksymov ,

To what I have seen at the moment, it seems that the problem is for the com.fasterxml.jackson.core:jackson-databind:2.9.4 library.

For the moment to bypass the error I have forced the use of the com.fasterxml.jackson.core:jackson-databind:2.9.3 library.

IgorMaksymov commented 6 years ago

@CarlosLoboZamarro thanks! In your explanation conflict and fix versions are the same. @jamesdbloom could you fix this issue? Because spring boot 2 provides this jackson dependency and its not good to exclude it from parent

CarlosLoboZamarro commented 6 years ago

Sorry @IgorMaksymov ,

I wanted to say com.fasterxml.jackson.core:jackson-databind:2.9.3 library.

For more data, here's the code that di thrown an error for me :

        oauthServer.when(
            request("/oauth/v2/access_token")
                .withMethod("GET")
                .withHeader("X-Correlation-Id", "70b10973-a064-41da-8a5b-5a4dacca9d15")
                .withQueryStringParameter("grant_type", "client_credentials")
                .withQueryStringParameter("scope", "SCOPE")
                .withHeader("authorization", "Basic Y2xpZW50SWQ6Y2xpZW50U2VjcmV0"))
                   .respond(response().withStatusCode(200)
                                      .withBody("{\"access_token\":\"the_great_access_token\",\"expires_in\":1000}"));

Upon debugging the deserializer complains about deserializing this array "grant_type" : [ "client_credentials" ].

Here's a whole stack trace :

Here's what changed with jackson-databind 2.9.4 : https://github.com/FasterXML/jackson-databind/blob/jackson-databind-2.9.5/release-notes/VERSION-2.x#L31-L61

I wonder if this was introduced by this issue / change https://github.com/FasterXML/jackson-databind/issues/1853

I used version 5.1.1 and it worked.

Also fails for jackson 2.8.11, which is a hotfix for a CVE. And the issue is gone in 2.9.2 (which doesn't have a hotfix for the CVE), and then fails again in 2.9.5. I didn't try 2.9.3 or 2.9.4 yet though. But the hotfix in 2.8.11 may be a clue.

Jackson 2.9.3 does work fine, as mentioned here previously.

nathanabercrombie commented 6 years ago

Agreed, 2.9.3 does work. 2.9.4 doesn't.

yanivnahoum commented 6 years ago

2.9.5 doesn't work either. Same error as 2.9.4

There is a bug in Jackson from version 2.9.4 onwards. The bug is because Jackson invalidly prevents deserialisation of JSON fields names for objects unless those objects are deserialised as a Map.

I have however worked around this bug with d267a2d5bc7f1b48abdf7ade0457244c7761d595.

Works great! Thanks

(Side note: You changed the names of some methods without having some deprecation period. I was on 5.3.0 and the method callback existed, now its called respond. That kind of change without a @Deprecated warning is kind of annoying)

Is there plans to update the mockserver maven plugin soon to use the latest version and to pull in this fix?
