Worklight 6.1 HTTPS Adapter: HttpHostConnectException with GET but Success with POST

StackOverflow https://stackoverflow.com/questions/22646024

Question

Worklight Developer Edition 6.1.

We are using the following code to call a simple HTTPS service that returns a redirect. From a Chrome browser the service can be called successfully with GET and POST.

With the Chrome Dev HTTP Client as well as with curl the call works fine:

curl -I https://XXX.ca/mobile
HTTP/1.1 302 Found
Date: Tue, 25 Mar 2014 20:50:21 GMT
Server: IBM_HTTP_Server
P3P: CP="NON UNI DEM IVAa IVDa STA PRE"
Location: https://XXX.ca/auth/Login?GAREASONCODE=-1&GARESOURCEID=sbip19&GAURI=https://XXX.ca/mobile&Reason=-1&APPID=sbip19&URI=https://XXX.ca/
mobile
Content-Type: text/html; charset=iso-8859-1

In an adapter with GET, we receive an HttpHostConnectException:

function testFlow() {
    var input = {
        path: 'mobile',
        method : 'get',
        returnedContentType : 'plain'
    };

    return WL.Server.invokeHttp(input);
}

With a POST we are successful:

Solution 2

This is currently being investigated by the Worklight development team to find whether this is a bug or not; if yes, a fix will be published.

OTHER TIPS

This ended up being a Worklight problem. [APAR PI14842: HTTPS GET PROBLEM WHEN USING WL.SERVER.INVOKEHTTP] (http://www.ibm.com/support/docview.wss?uid=swg1PI14842)

When an HTTPS GET request results in a HTTP 302 redirect response, the invokeHttp method will stall until it times out and then ends with

Runtime: Http request failed:
org.apache.http.conn.HttpHostConnectException: Connection to https:\/\/XXX.ca refused

You can watch APAR PI14842 to find out when a fix will be available.

Perhaps you did not implement the "get method" as the same with "post method". Could you check or paste the codes the adapter trying to invoke

Looking at the API docs for WL.Server.invokeHttp, it doesn't seem like 'path' is listed as values it accepts.

From the error you are getting, it also doesn't seem like it's using it either on a GET. The connection is probably being refused because it attempts to connect to https://XXX.ca instead of https://XXX.ca/mobile ?
