Restful Service Registry Response Format

[Dewi Suci Rafianti]

Hello, 

I'm configuring CAS v6.3 to use restful service registry based on this documentation (https://apereo.github.io/cas/6.3.x/services/REST-Service-Management.html#restful-service-registry).

When I run CAS server, I got error like this. 

Caused by: org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Cannot deserialize value of type `[Ljava.io.Serializable;` from Object value (token `JsonToken.START_OBJECT`); nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize value of type `[Ljava.io.Serializable;` from Object value (token `JsonToken.START_OBJECT`) at [Source: (PushbackInputStream); line: 1, column: 1] at org.springframework.http.converter.json.AbstractJackson2HttpMessageConverter.readJavaType(AbstractJackson2HttpMessageConverter.java:285) at org.springframework.http.converter.json.AbstractJackson2HttpMessageConverter.read(AbstractJackson2HttpMessageConverter.java:243) at org.springframework.web.client.HttpMessageConverterExtractor.extractData(HttpMessageConverterExtractor.java:105) ... 193 more Caused by: com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize value of type `[Ljava.io.Serializable;` from Object value (token `JsonToken.START_OBJECT`) at [Source: (PushbackInputStream); line: 1, column: 1] at com.fasterxml.jackson.databind.exc.MismatchedInputException.from(MismatchedInputException.java:59) at com.fasterxml.jackson.databind.DeserializationContext.reportInputMismatch(DeserializationContext.java:1603) at com.fasterxml.jackson.databind.DeserializationContext.handleUnexpectedToken(DeserializationContext.java:1377) at com.fasterxml.jackson.databind.DeserializationContext.handleUnexpectedToken(DeserializationContext.java:1324) at com.fasterxml.jackson.databind.deser.std.ObjectArrayDeserializer.handleNonArray(ObjectArrayDeserializer.java:343) at com.fasterxml.jackson.databind.deser.std.ObjectArrayDeserializer.deserialize(ObjectArrayDeserializer.java:194) at com.fasterxml.jackson.databind.deser.std.ObjectArrayDeserializer.deserialize(ObjectArrayDeserializer.java:24) at com.fasterxml.jackson.databind.deser.DefaultDeserializationContext.readRootValue(DefaultDeserializationContext.java:322) at com.fasterxml.jackson.databind.ObjectMapper._readMapAndClose(ObjectMapper.java:4591) at com.fasterxml.jackson.databind.ObjectMapper.readValue(ObjectMapper.java:3599) at org.springframework.http.converter.json.AbstractJackson2HttpMessageConverter.readJavaType(AbstractJackson2HttpMessageConverter.java:274) ... 195 more

Here is the rest api response that I provided. 

{"@class" : "org.apereo.cas.services.RegexRegisteredService", 

  "serviceId" : "^(https|imaps)://.*", 

  "name" : "HTTPS and IMAPS", 

  "id" : 10000001}

It's in JSON format. Is there any specific format that I should provide?

Thank you

[Pablo Vidaurri]

are you returning a 200?

Is that JSON what you actually received or is it what you think you are sending?

[Pablo Vidaurri]

Since you have it setup as a webservice, have you tried calling postman to see what you actually get back?

[Dewi Suci Rafianti]

Thank you for your answer. 

Yes, it happens because of some error in webservice.

Now, CAS can access service registry with this format from rest api

{

   "@class" : "org.apereo.cas.services.RegexRegisteredService", 

   "serviceId" : "^(https|imaps)://.*", 

   "name" : "HTTPS and IMAPS", 

   "id" : 10000001

}

However, I need to add attribute release policy to service registry. So the format will be like this.

{

   "@class": "org.apereo.cas.services.RegexRegisteredService",

   "serviceId": "^(http|https)://localhost.*",

   "name": "Localhost",

   "id": "25062021",

   "evaluationOrder": 0, 

   "description": "localhost app",

   "logoutType": "BACK_CHANNEL",      

   "responseType": "REDIRECT",

   "attributeReleasePolicy": {

       "@class": "org.apereo.cas.services.ReturnAllowedAttributeReleasePolicy",

       "allowedAttributes": ["java.util.ArrayList",["cn","sn","mail","employeeNumber"]]

    }

}

But, I got error like this 

java.lang.IllegalArgumentException: Cannot deserialize value of type `java.lang.String` from Array value (token `JsonToken.START_ARRAY`)

Is the format not right? I got the format from CAS documentation.

[He Vincent]

I think JSON, all shoul use {}, here is my example:

  "attributeReleasePolicy" : {

    "@class" : "org.apereo.cas.services.ReturnMappedAttributeReleasePolicy",

    "allowedAttributes" : {

      "@class" : "java.util.TreeMap",

      "givenName" : "firstname",

      "sn" : "lastname",

      "email" : "email"
