Class BaseExpressionHttpResponseInterceptor

java.lang.Object

com.mulesoft.connectivity.rest.commons.internal.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

evaluate

protected <T> org.mule.runtime.api.metadata.TypedValue<T> evaluate(String expression,
                                                                   org.mule.runtime.api.el.ExpressionLanguageSession session,

Evaluates an expression giving the bindingContext and dataType.

Type Parameters:

T - type of the output TypedValue.

Parameters:

expression - to be evaluated.

session - expression language session.

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

Returns:

the result of the evaluation as TypedValue.

intercept

public org.mule.runtime.http.api.domain.message.response.HttpResponse intercept(HttpRequest httpRequest,
                                                                                org.mule.runtime.http.api.domain.message.response.HttpResponse httpResponse)

Description copied from interface: HttpResponseInterceptor

Process an HttpResponse and generate a new one or return the one provided.

Specified by:

intercept in interface HttpResponseInterceptor

Parameters:

httpRequest - the HTTP request that was executed against the server.

httpResponse - the server response to be intercepted. Entity's content could not be read more than once, so implementations should address this when content needs to be accessed more than once.

Returns:

the same or a new and modified HttpResponse.
