Request Parameters doubled

[JohannesFluegel]

I use Spring REST Docs 1.1.1.RELEASE.

My url contains request parameters as described in
Spring REST Docs documentation: Request parameters:

this.mockMvc.perform(get("/devices?page=2&per_page=100")).andDo(document("document"));

http-request.adoc contains

GET /devices?page=2&per_page=100&page=2&per_page=100 HTTP/1.1

The request parameters are doubled.

Duplicates #286. The problem's fixed in 1.1.2.RELEASE. It's always worth trying the latest version before reporting an issue.

In 1.1.2.RELEASE the error occurs again if I want to change the parameter values.

private static OperationPreprocessor myPreprocessor() {
    return new OperationPreprocessor() {

        @Override
        public OperationResponse preprocess(OperationResponse response) {
            return new OperationResponseFactory().create(response.getStatus(), response.getHeaders(),
                    response.getContent());
        }

        @Override
        public OperationRequest preprocess(OperationRequest request) {
            return new OperationRequestFactory().create(
                    URI.create(request.getUri().toString().replaceFirst("change-me", "changed")),
                    request.getMethod(), request.getContent(), request.getHeaders(), request.getParameters(),
                    request.getParts());
        }
    };
}

@Test
public void myTest() {
    this.mockMvc.perform(get("/devices?param=change-me"))
            .andDo(document("nok", preprocessRequest(myPreprocessor())));
...

returns
GET /devices?param=changed&param=change-me HTTP/1.1

[wilkinsona]

I suspect that's because param=change-me has already made it into the Map returned by request.getParameters(). What happens if you update the parameters map too?

[JohannesFluegel]

With

@Override
public OperationRequest preprocess(OperationRequest request) {
    request.getParameters().clear();
    return new OperationRequestFactory().create(
    ...

it works fine.
