Re: XML input and Output

Hi Patrick,

I am a begginer, the sample application what i tried initally was just to display some posters and click the poster to play video. I used the videoplayer example soure code and modified categories.brs for input xml . I had all other xmls to display Info.
conn.UrlPrefix = "http://rokudev.roku.com/rokudev/examples/videoplayer/xml<-- replaced with my xml directory"
conn.UrlCategoryFeed = conn.UrlPrefix + "/categories.xml<-- replaced with my xml page"

Now i want to try the same thing with webserivce HTTP POST request instead of directly giving the xml soruce as categories.xml. I have webservice which accepts only XML input and returns the categories.xml as ouput.

where can i find the sample code for HTTP Post request
which ifUrlTransfer interface function i have to use for HTTP POST request.

Re: XML input and Output

There is no synchronous roUrlTransfer method for an HTTP Post. Instead, use the asynchronous method AsyncPostFromString() or AsyncPostFromFile() to post the Body.

Example:

url = "<your POST URL>"
body = "<your POST Body>"

obj = CreateObject("roUrlTransfer")
obj.SetPort(CreateObject("roMessagePort"))
obj.SetUrl(url)

timeout% = 1500
num_retries% = 5
str = ""
while num_retries% > 0
if (obj.AsyncPostFromString(body))
event = wait(timeout%, obj.GetPort())
if type(event) = "roUrlEvent"
respCode = event.GetResponseCode()
if respCode = 200 then
return event.GetString()
else
return invalid
end if
elseif event = invalid
obj.AsyncCancel()

obj = CreateObject("roUrlTransfer")
obj.SetPort(CreateObject("roMessagePort"))
obj.SetUrl(url)
timeout% = 2 * timeout%
else
print "roUrlTransfer::AsyncPostFromString(): unknown event"
endif
endif
num_retries% = num_retries% - 1
end while

Re: XML input and Output

Can this method be used to send commands? select home, select up, etc...?

What would it look like?

Re: XML input and Output

ErlyD, there is not currently a documented way to send commands to the Roku DVP. There is a way, but we are looking at formalizing a new interface for doing this. Look for more info soon...

hpatel18, You can use the techniques earlier in this thread to consume your web service. You are basically using these components; roUrlTransfer to GET/POST http connections. You will send String xml requests and parse responses using roXMLElement and roXMLList or the BrightScript language XML support.
