I want to add feature to export document as PDF

[JaneSoo]

Hi, I was looking for a feature to export documents as PDFs but there is nothing. I want to try adding this feature to the project however I am not sure if it's achievable. At least when I looked for REST API, there is no such feature but when I looked into WSDL, I saw this
<wsdl:message name="exportDocumentToPDFResponse"><wsdl:part element="tns1:exportDocumentToPDFResponse" name="parameters" /></wsdl:message> and I got some hope. Can anybody tell me if it's possible? And if yes, I'd like a bit of guidance, and then I can start implementing this feature. Thanks

@waynesun09 Could I get some of your opinions?

[waynesun09]

So for the WSDL function it could be the exportDocumentToPDF

<wsdl:operation name="exportDocumentToPDF">
<wsdl:documentation xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"> Export a document to PDF and download it. @param uri Module/Document URI. @param exportPdfProperties Export parameters. <br> paperSize - the size of the page for export. Possible values are A4, A3, Letter, Legal, Tabloid.<br> orientation - the orientation of the page. Possible values are Portrait or Landscape. <br> fitToPageWidth - true to fit to the page width. <br> generateBookmarks - true to generate bookmarks. <br> includeHeaderFooter - true to include header, footer and watermark. @since 3.20.1 </wsdl:documentation>
<wsdl:input message="impl:exportDocumentToPDFRequest" name="exportDocumentToPDFRequest"/>
<wsdl:output message="impl:exportDocumentToPDFResponse" name="exportDocumentToPDFResponse"/>
</wsdl:operation>

implement it under Document module should work

Could you add a test under src/unit_tests/document_test.py with output a pdf file, it's better we could check the file is a valid pdf with pdf library but check the path exist should be fine without add a new dependency.

Sure, here is the draft PR: #145

I couldn't see in WSDL function regarding output file :/ should I assume it will output in the current directory?

[waynesun09]

The return is base64Binary, you need use base64 decode and write it to a file

as in the WSDL:

<element name="exportDocumentToPDFResponse">
<complexType>
<sequence>
<element name="exportDocumentToPDFReturn" type="xsd:base64Binary"/>
</sequence>
</complexType>
</element>```
