I've got a file in a Play!2 app that I want to send to a web service call. I want a reactive way to read the file and send it. I want something like the following:
val source = Source.fromFile("/path/to/someFile")
val holder: WSRequestHolder = WS.url("http://example.com/service")
val futureResult = holder.post(source)
futureResult.onComplete({source.close()})
But the above code does not compile.
Is there an idiomatic way to reactively stream a file to a web service?
I've found out that this is, in fact, very easy with Play's build in web services:
WS.url("http://http://example.com/service/").post(new io.File("path/to/someFile"))
That is, the post function can take a File option, and, presumably, streams correctly.

I've just created a service consumer and generated its code from ABAP in order to send to the target WSDL system XML file which is created successfully.
The code should fill in the XML_FILE_INFO fields but have no idea if I did it OK:
The code to activate it:
" Call method, and receive a response
try.
lo_proxy->SET_MESSAGE(
exporting
INPUT = gs_input
importing
OUTPUT = ls_output
).
catch CX_AI_SYSTEM_FAULT INTO lo_AI_SYSTEM_FAULT. "lo_ai_system_fault_info.
catch CX_AI_APPLICATION_FAULT INTO LO_AI_APPLICATION_FAULT.
ENDTRY.
How should I fill the XML file's content in the GS_INPUT structure? IS putting the file's path in the FILE_NAME field enough?
If someone had already done something like the mentioned requirement I'd appreciate any help.
Thanks in advance.
I need to build a message flow where I am supposed to trigger a message(which is combination of numbers and alphabets simply a Id no) to a URL through HTTP request node and get a flat file in response(EDI Data). I have coded and I want to test whether my flow is working.
For this I need to create a mock service and construct a flat file. My question is how I can construct the response. Any proper code to write flat files(EDI data) so that I can get that as response and make sure my flow is working.
This is how exactly my response should look like:
EDI_BA40 125566 INVOIC LS 0036566
.......... and so on
Please provide some solution so that I can receive this in my response or something that I can do to test my flow so that there would be no error when I move my code next environment(QAL/PRD).
I am new to the wsdl\soapmessage query\reply world( if i can put it in this way), and I am facing some difficulties using the following wsdl( which I really really hope, one will be so kind to look at at least one of the services described there)
http://almdemo.polarion.com/polarion/ws/services/TrackerWebService?wsdl
which was provided to me to develop a matlab webinterface. Right now my matlab code looks like this:
targetNamespace = 'http://ws.polarion.com/TrackerWebService';
method = 'queryWorkItems';
values= {'Query','Sort'}
names = {'query', 'sort'}
types ={'xsd:string','xsd:string'}
message = createSoapMessage( targetNamespace, method, values, names, types)
response = callSoapService('http://almdemo.polarion.com/polarion/ws/services',...
% Service's endpoint
'http://almdemo.polarion.com/polarion/#/workitems',...
% Server method to run
message)
% SOAP message created using createSoapMessage
author = parseSoapResponse(response)
Herewith to save you time I will just enonce my two problems:
Is the code correct?
Could someone tell me if such a wsdl link is just a definition of webservices or it is also a service's endpoint?
Normally to execute manually\per clicks this services on the weppage
http://almdemo.polarion.com/polarion, you have to login!
So how do I send a message in matlab which first log me in? Or must such a service be introduced into that wsdl for me to do it?? Could you be kind enough to write how it must be defined, because I don't really
write wsdl files, but I shall learn!**
I will be really thankful for your help and I wish you a happy week(-end) guys(& girls)!!!
Regards
Chrysmac
ps: I tried to use Soapui and gave that webpage as endpoint, but the toool crashes each time I enter my credentials! Maybe because of the dataload!??
I need to create a simple web service (being the "server"). The goal is to provide some data I do read in an Qt / C++ application as JSON data. Basically a JavaScript application in the browser shall read its data from the Qt app. It is usually a single user scenario, so the user runs a Google Maps application in her browser, while additional data come from the Qt application.
So far I have found these libs:
Qxt: http://libqxt.bitbucket.org/doc/0.6/index.html but being a newbie on C++/Qt I miss some examples. Added: I have found one example here
gSoap: http://www.cs.fsu.edu/~engelen/soap.html has more examples and documentation and also seems to support JSON
KD SOAP: http://www.kdab.com/kdab-products/kd-soap/ with no example as far as I can tell, docu is here
Qt features itself, but it is more about acting as a client: http://qt-project.org/videos/watch/qt-networking-web-services
Checking SO gives me basically links to the above libs
webservice with Qt with an example I do not really get.
How to Create a webservice by Qt
So basically I do have the following questions:
Which lib would you use? I want to keep it as simple as possible and would need an example.
Is there another (easy!) way to provide the JSON data to the JavaScript Web page besides the WebService?
-- Edit, remarks: ---
Needs to be application intrinsic. No web server can be installed, no extra run time can be used. The user just runs the app. Maybe the Qt WebKit could be an approach....
-- Edit 2 --
Currently checking the tiny web servers as of SO " Qt HTTP Server? "
As of my tests, currently I am using QtWebApp: http://stefanfrings.de/qtwebapp/index-en.html This is one of the answers of Edit 2 ( Qt HTTP Server? )
Stefan's small WebServer has some well documented code, is written in "Qt C++" and easy to use, especially if you have worked with servlets already. Since it can be easily integrated in my Qt project, I'll end up with an internal WebServer.
Some demo code from my JSON tests, showing that generating the JSON content is basically creating a QString.
void WebServiceController::service(HttpRequest& request, HttpResponse& response) {
// set some headers
response.setHeader("Content-Type", "application/json; charset=ISO-8859-1");
response.setCookie(HttpCookie("wsTest","CreateDummyPerson",600));
QString dp = WebServiceController::getDummyPerson();
QByteArray ba = dp.toLocal8Bit();
const char *baChar = ba.data();
response.write(ba);
}
If someone has easy examples with other libs to share, please let me know.
QByteArray ba = dp.toLocal8Bit();
const char *baChar = ba.data();
You don't need to convert the QByteArray to char array. Response.write() can also be called with a QByteArray.
By the way: qPrintable(dp) is a shortcut to convert from QString to char array.
I notice that Growl allows for the possibility of Growl notifications from a website. Has anyone tried implementing this?
If so, what form did it take? Did you implement multi user support? And, can you provide any code examples (C# or Objective-C would preferable but I'm not that fussed)?
Rich
There are GNTP (Growl Network Transport Protocol) bindings for various languages, a list of bindings can be found here - these allow you to send notifications from, say, a PHP script.
I wouldn't trust Growl's UDP system directly, but rather write a server that receives and stores notifications (maybe as a tiny web app), and a local script that routinely grabs any new messages via HTTP and Growls them. Not complicated at all, will be more reliable than UDP, and can queue up messages when your Growl'ing machine is powered-off or unreachable. Shouldn't take long to implement
Basically, server.php in pseudo-PHP (which could use Net_Growl):
<?php
if($_GET['action'] == "store"){
$title = $_POST['title'];
$message = $_POST['message'];
$password = sha1($_POST['password']);
if($password == "..."){
store_in_database(sanitise($title), sanitise($message);
}
} else {
print(json_encode(get_notifications_from_database()));
mark_notifications_as_read();
}
?>
client.py in pseudo-Python (which could use gntp):
while 1:
time.sleep(60):
data = urllib.urlopen("http://myserver.com/server.php?action=get&password=blah").read()
for line in data:
notif = json.decode(line)
growl.alert(notif['title'], notif['message'])
