Saleforce sites as listener/handler for http POST?

Hi everyone,

Does anyone have any experience/example code with setting a sites page to function as a listener/handler for an http POST?

Thanks!

it's fairly simple. in the visualforce page's controller, you just end up using the

ApexPages.CurrentPage().getParameters().get("param") method for all the params you need. I found that this works for both HTTP GET and POST handling in my testing.

What paul-lmi suggests will work great when you are looking for name value pairs.
But in my case, where I want to receive an XML POST via HTTPS, is there a way for me to see the whole HTTP POST message?

In other programming languages, there would be a function to get the HTTPRequest content... I can't seem to find a way to get the entire message.

Can anyone provide me with some ideas to try?
Thanks!
Erik

look at the apex documentation in regards to HTTP and HTTPRequest. I know there's a setBody() method, so I'm presuming there's a getBody() one too.

Thanks Paul-lmi,

I can call the getParameters function to see this stuff:
MAP<String,String> pmtrs= ApexPages.currentPage().getParameters();
For others out there accepting an XML message via post, here's my plan
Grab the parameters string using getParameters
then search for the beginning of the XML: <?xml version
And work from there...
I will keep you posted.

Update: So close, but this doesn't work: getParameters() appears to only be able to return a Map of name value pairs. And since an XML string is not Name Value, you just get a null string back... bummer
Here is my supporting evidence: debug logs of a CGI post vs an XML post:

CGI/Name-Value pair example:
Here is the debug log for the sendings system:
[03-12-09 13:56:42][DEBUG]: MultiServerMode is off and CategoryMode is off; running ALL scheduled engines
[03-12-09 13:56:42][INFO]: XSL file name: 1259877402.xsl
[03-12-09 13:56:42][WARN]: Required credentials not available for BASIC <any realm>@edy2007-developer-edition.na3.force.com:80
[03-12-09 13:56:42][WARN]: Preemptive authentication requested but no default credentials available

// the part below is a well formatted HTTP POST CGI message

[03-12-09 13:56:42][DEBUG]: >> "POST / HTTP/1.1[\r][\n]"
[03-12-09 13:56:42][DEBUG]: >> "User-Agent: Jakarta Commons-HttpClient/3.0.1[\r][\n]"
[03-12-09 13:56:42][DEBUG]: >> "Host: edy2007-developer-edition.na3.force.com[\r][\n]"
[03-12-09 13:56:42][DEBUG]: >> "Content-Length: 1439[\r][\n]"
[03-12-09 13:56:42][DEBUG]: >> "Content-Type: application/x-www-form-urlencoded[\r][\n]"
[03-12-09 13:56:42][DEBUG]: >> "[\r][\n]"
[03-12-09 13:56:42][DEBUG]: >> "B2_MailCity=&REAgentPhone=&FirstMortgageBalance
…..

And here is what getParameters finds:
ApexPages.currentPage()getParameters() ={AdditionalInformation=, B2_BirthDate=, B2_FirstName=, B2_GrossMonthlyIncome=, B2_LastName=, B2_MailCity=, B2_MailState=, B2_MailStreetAddress=, B2_MailZipCode=, B2_SSN=, ...}

//the values are blank, but at least it finds the data. (the data is returned in a alphabetically
//organized Map, so the A, and Bs come first... there is data in later variables...

XML posting example:
Here is the debug log for the sendings system:
[03-12-09 13:45:18][DEBUG]: MultiServerMode is off and CategoryMode is off; running ALL scheduled engines
[03-12-09 13:45:18][INFO]: XSL file name: 1259876718.xsl
[03-12-09 13:45:19][WARN]: Required credentials not available for BASIC <any realm>@edy2007-developer-edition.na3.force.com:80
[03-12-09 13:45:19][WARN]: Preemptive authentication requested but no default credentials available

// the part below is a well formatted HTTP POST XML message

[03-12-09 13:45:19][DEBUG]: >> "POST / HTTP/1.1[\r][\n]"
[03-12-09 13:45:19][DEBUG]: >> "Content-Type: text/xml[\r][\n]"
[03-12-09 13:45:19][DEBUG]: >> "User-Agent: Jakarta Commons-HttpClient/3.0.1[\r][\n]"
[03-12-09 13:45:19][DEBUG]: >> "Host: edy2007-developer-edition.na3.force.com[\r][\n]"
[03-12-09 13:45:19][DEBUG]: >> "Content-Length: 2304[\r][\n]"
[03-12-09 13:45:19][DEBUG]: >> "[\r][\n]"
[03-12-09 13:45:19][DEBUG]: >> "<?xml version="1.0" encoding="UTF-8"?>[\n]"
[03-12-09 13:45:19][DEBUG]: >> "<Leads xmlns="http://www.<removedtoprotecttheinnocent>.com/hla/2006">[\n]"
[03-12-09 13:45:19][DEBUG]: >> "<Lead>[\n]"
[03-12-09 13:45:19][DEBUG]: >> "<LeadType>1</LeadType>[\n]"
[03-12-09 13:45:19][DEBUG]: >> "<LeadID>222838775</LeadID>[\n]"
...

And here is what getParameters finds:
ApexPages.currentPage()getParameters() ={} <--- LOOK HERE ***** The braces {} are empty!

And I am unable to find the getBody() function apparently we all desire: there is an ideaexchange idea to allow access to Raw XML post data:
http://ideas.salesforce.com/article/show/10093914/Enable_Access_to_Raw_Post_Data_in_Visualforce_Pages

Rock the vote!

Hello,

We are developing an XML listener (service) as a Sites page.

We are using getContent() to obtain the XML content posted (via HTTP POST) without parameters. To be more specific, this is not through a form POST.

When I call xmlBody.toString() based on the code below, it returns nothing.

VF page Coding

<apex:page controller="InboundProcessor" action="{!init}" showHeader="false" sidebar="false"></apex:page>

ApexClass Coding

public PageReference init() {
   PageReference xml = new PageReference(ApexPages.currentPage().GetURL());
   Blob xmlBody = xml.getContent();

   System.debug('blobcontent::'+xmlBody);
   System.debug('xmlStringcontent::'+xmlBody.toString());

}

Is there any issue with getContent()?

How'd you guys go getting this working? That is, a sites page able to receive an xml file and parse it?

I used content type 'application/x-www-form-urlencoded' in my HTTP POST (sending from Excel VBA test code) and then did the following to get the body in Salesforce:

string body = '';
MAP<string, string> params = ApexPages.currentPage().getParameters();
for (string paramname : params.keySet() )
body += paramname + '=' + params.get(paramname) + '\n';
if (body.endsWith('=\n')) {
body = body.substring(0,body.length()-2);
}

I do not get any parameters when I set the content-type of the HTTP POST to 'text/xml'. Does anybody know how to get it working with 'text/xml'?

We are trying to do something similar, but need to look at the Parameter and then respond back with a specific XML response based on the type of request. Is this possible?

Here is an example of our VisualForce page:

<apex:page showHeader="false" contentType="text/xml" controller="HttpController" action="{!processRequest}"> <apex:outputPanel rendered="{!action='getmodule'}"> <Response moduleVersion="3.0.1" schemaVersion="1.0.0" > <Module> <Platform>Force.com</Platform> <Capabilities> <DownloadStrategy>ByModifiedTime</DownloadStrategy> </Capabilities> </Module> </Response> </apex:outputPanel> <apex:outputPanel rendered="{!action='getcount'}"> <Response moduleVersion="3.0.1" schemaVersion="1.0.0" > <count>1</count> </Response> </apex:outputPanel> </apex:page>

Or, maybe we can set the HTTP response in the controller?

Thanks,
Jon
