Unreadable PDF file

[PYBurosse]

Hello,

So I'm not sure this is actually a bug, but I can't get the API working using java (groovy/grails to be precise). I use the java HttpClient and MultipartEntity to create the http request, containing the remoteURL of the page I want to make into a PDF. The API do gives me what seems to be a PDF file, but it cannot be opened, neither by a local pdf viewer or the browser, both telling me that the file seems to be damaged or in an unsupported format.
Here is the code I use :

static def execute(def apiURL){
        def httpClient = HttpClients.createDefault()
        def request = new HttpPost(apiURL)

        MultipartEntityBuilder builder = MultipartEntityBuilder.create()
        builder.addTextBody("remoteURL", 'https://google.com')
        builder.addTextBody("marginTop", '0')
        builder.addTextBody("marginBottom", '0')
        builder.addTextBody("marginLeft", '0')
        builder.addTextBody("marginRight", '0')


        HttpEntity multipart = builder.build()
        request.setEntity(multipart)
        def response = httpClient.execute(request)

        BufferedReader rd = new BufferedReader(
                new InputStreamReader(response.getEntity().getContent()))

        StringBuffer result = new StringBuffer()
        String line = ""

        while ((line = rd.readLine()) != null) {

            result.append(line)
        }
        return result
}

I do get a StringBuffer starting with
"%PDF-1.4%����1 0 obj<</Creator (Chromium)/Producer (Skia/PDF m74)/CreationDate (D:20190510164315+00'00')..."
that's why I say it looks like a PDF file.

I am sure the API works fine, since when I do a curl request, from a terminal or from my java project, I do have a proper PDF file. I can't use the curl request in my code, though, because it download the file into my project, instead of giving it as a variable I can easily use and convert as base64.
I am coming here for help since I can't figure out if the problem is from my request or the API, so if anyone has an idea, that would be great

Hello @PYBurosse

I have no idea why it does not work with your code. Maybe an encoding issue?
