Class BaseExpressionHttpResponseInterceptor

java.lang.Object

com.mulesoft.connectivity.rest.commons.api.interception.expression.BaseExpressionHttpResponseInterceptor

All Implemented Interfaces:

HttpResponseInterceptor

Direct Known Subclasses:

ExpressionHttpResponseInterceptor

public abstract class BaseExpressionHttpResponseInterceptor
extends Object
implements HttpResponseInterceptor

A base implementation for a HttpResponseInterceptor that relies on DW expressions. It allows use of DW expressions to define the matching condition and transformations for statusCode, reasonPhrase, headers and body.

BindingContext provided on each expression has the original HttpResponse data with the following variables:

• statusCode: int
• reasonPhrase: String
• headers: MultiMap
• body: InputStream

Since:

1.0

Method Detail

createBindingContext

protected org.mule.runtime.api.el.BindingContext createBindingContext(InterceptionHttpRequest httpRequest,
                                                                      org.mule.runtime.http.api.domain.message.response.HttpResponse httpResponse)

Creates a BindingContext with data resolved from the HttpResponseInterceptor and HttpResponse as variables:

• request: HttpResponseInterceptor
• statusCode: int
• reasonPhrase: String
• headers: MultiMap
• body: InputStream

Parameters:

httpRequest - the request to be injected to the binding context.

httpResponse - the response to retrieve the values for variables related to response.

Returns:

a BindingContext.

getMediaType

protected org.mule.runtime.api.metadata.MediaType getMediaType(org.mule.runtime.http.api.domain.message.response.HttpResponse httpResponse)

evaluate

protected <T> org.mule.runtime.api.metadata.TypedValue<T> evaluate(String expression,
                                                                   org.mule.runtime.api.el.BindingContext bindingContext,
                                                                   org.mule.runtime.api.metadata.DataType dataType,
                                                                   org.mule.runtime.api.el.ExpressionLanguage expressionLanguage)

Evaluates an expression giving the bindingContext and dataType.

Type Parameters:

T - type of the output TypedValue.

Parameters:

expression - to be evaluated.

bindingContext - to be provided for the expression language.

dataType - the output DataType for the result of the expression evaluation.

expressionLanguage - ExpressionLanguage to delegate the invocation.

Returns:

the result of the evaluation as TypedValue.
