How to export a Confluence "Space" to PDF using remote API - ruby

Question

How can I export a Confluence 'space' as a pdf? It looks like it might still be supported in Confluence 5.0 using the XML-RPC API. I cannot find an example of what to call, though.
https://developer.atlassian.com/display/CONFDEV/Remote+API+Specification+for+PDF+Export#RemoteAPISpecificationforPDFExport-XML-RPCInformation
That link says calls should be prefixed with pdfexport, but then doesn't list any of the calls or give an example.

This works using Bob Swift's SOAP library ('org.swift.common:confluence-soap:5.4.1'). I'm using this in a gradle plugin, so you'll need to change a few things
void exportSpaceAsPdf(spaceKey, File outputFile) {
// Setup Pdf Export Service
PdfExportRpcServiceLocator serviceLocator = new PdfExportRpcServiceLocator()
serviceLocator.setpdfexportEndpointAddress("${url}/rpc/soap-axis/pdfexport")
serviceLocator.setMaintainSession(true)
def pdfService = serviceLocator.getpdfexport()
// Login
def token = pdfService.login(user, password)
// Perform Export
def pdfUrl = pdfService.exportSpace(token, spaceKey)
// Download Pdf
HttpClient client = new DefaultHttpClient();
HttpGet httpget = new HttpGet(pdfUrl)
httpget.addHeader(
BasicScheme.authenticate(
new UsernamePasswordCredentials(user,password),"UTF-8", false))
HttpResponse response = client.execute(httpget)
HttpEntity entity = response.getEntity()
if (entity != null) {
InputStream inputStream = entity.getContent()
FileOutputStream fos = new FileOutputStream(outputFile)
int inByte
while ((inByte = inputStream.read()) != -1)
fos.write(inByte)
inputStream.close()
fos.close()
} else {
throw new GradleException("""Cannot Export Space to PDF:
Space: ${spaceKey}
Dest: ${outputFile.absolutePath}
URL: ${pdfUrl}
Status: ${response.getStatusLine()}
""")
}
}

I know this is a PHP example, not Ruby, but you can check out the XML-RPC example in VoycerAG's PHP project on Github at https://github.com/VoycerAG/confluence-xmlrpc-pdf-export/blob/master/src/Voycer/Confluence/Command/PdfExportCommand.php ... hope it helps.
Basically you just need to make a call to the login method and user the authentication token returned to make a call to the exportSpace method. That in turn gives you back a URL which an authenticated user can then download the PDF from.

Turns out the soap API is the only currently available api for exporting a space
Using the Savon library in Ruby here:
require 'savon'
# create a client for the service
# http://<confluence-install>/rpc/soap-axis/pdfexport?wsdll
client = Savon.client(wsdl: 'https://example.atlassian.net/wiki/rpc/soap-axis/pdfexport?wsdl', read_timeout: 200)
# call the 'findUser' operation
response = client.call(:login, message: {username: "user", password: "pass"})
token = response.body[:login_response][:login_return]
response = client.call(:export_space, message:{token: token, space_key: "SPACE KEY"})
