this question might sound a little bit weired... But I will try to explain:
I got an Android App, that makes calls against a RAP-Build Website (to that I only have access via Webbrowser).
Until now I am sending pure HTTP Requests for example:
HttpPost request = new HttpPost(url + ";jsessionid=" + jsessionid
+ "?nocache=" + System.currentTimeMillis()
+ "&org.eclipse.swt.events.widgetSelected=w131"
+ "&requestCounter=" + (requestCounter++) + "&uiRoot=w1"
+ "&w1.cursorLocation.x=282" + "&w1.cursorLocation.y=148");
then I get back a lot of stuff like this:
var wm = org.eclipse.swt.WidgetManager.getInstance(); [...] ;
wm.add( w, "w17", true );[...];w.setCaption( "THIS IS WHAT I NEEED" );
Then I use some complex Regular Expressions to parse what I want and send back another post with the actions.
But to get to my question: Is there an easier way to do this? Does RAP perhaps have a build in API for such external requests oder does a JAVA Library exist, that makes communication with RAP easier.
I hope you did understand my problem - if not please leave a comment and I will try to explain it further.
Thanks!
Here you can see the example "How to provide download link?" You can change the example to work in your way providing custom service handler and using it from the Android App.

I am trying to call Google Analytics Data API (GA4) using the Java client library and applying a dimension filter. This is the call which is working if I don't use the setDimensionFilter call:
RunReportRequest request =
RunReportRequest.newBuilder()
.setProperty(propertyId)
.addDimensions(com.google.analytics.data.v1beta.Dimension.newBuilder().setName("pageLocation"))
.addMetrics(com.google.analytics.data.v1beta.Metric.newBuilder().setName("screenPageViews"))
.addMetrics(com.google.analytics.data.v1beta.Metric.newBuilder().setName("activeUsers"))
// .setDimensionFilter(FilterExpression.newBuilder().setFilter(Filter.newBuilder().setStringFilter(
// Filter.StringFilter.newBuilder()
// .setMatchType(Filter.StringFilter.MatchType.FULL_REGEXP)
// .setField(Descriptors.FieldDescriptor, "pageLocation")
// .setValue("MY_REGEXP")
// .build())))
.addDateRanges(com.google.analytics.data.v1beta.DateRange.newBuilder()
.setStartDate(startDate.toStringYYYYMMDDWithDashes())
.setEndDate(endDate.toStringYYYYMMDDWithDashes()))
.setKeepEmptyRows(true)
.build();
I don't know how to use setDimensionFilter. If the usage which is commented in the previous code is correct, then the only thing missing is the call to setField. I don't know how to generate the Descriptors.FieldDescriptor instance (or even its meaning).
I have reviewed the client library javadoc, and also the code samples (which are really simple and unfortunately do not show any usage of setDimensionFilter).
The Descriptors.FieldDescriptor isn't part of the GA4 Data API and is an internal functionality of the protobuf framework
If you are trying to call this filter on a field with the name 'pageLocation' instead of using setField, I think you can do something like this
RunReportRequest request =
RunReportRequest.newBuilder()
.setProperty("properties/" + propertyId)
.addDimensions(com.google.analytics.data.v1beta.Dimension.newBuilder().setName("pageLocation"))
.addMetrics(com.google.analytics.data.v1beta.Metric.newBuilder().setName("screenPageViews"))
.addMetrics(com.google.analytics.data.v1beta.Metric.newBuilder().setName("activeUsers"))
.setDimensionFilter(FilterExpression.newBuilder()
.setFilter(Filter.newBuilder()
.setFieldName("pageLocation")
.setStringFilter(Filter.StringFilter.newBuilder()
.setMatchType(Filter.StringFilter.MatchType.FULL_REGEXP)
.setValue("MY_REGEXP"))))
.addDateRanges(com.google.analytics.data.v1beta.DateRange.newBuilder()
.setStartDate("2020-03-31")
.setEndDate("2021-03-31"))
.build();
Also, if you want an additional example of how to use setDimensionFilter, here is another code example that might help
RunReportRequest request =
RunReportRequest.newBuilder()
.setProperty("properties/" + propertyId)
.addDimensions(Dimension.newBuilder().setName("city"))
.addMetrics(Metric.newBuilder().setName("activeUsers"))
.addDateRanges(DateRange.newBuilder().setStartDate("2020-03-31").setEndDate("today"))
.setDimensionFilter(FilterExpression.newBuilder()
.setAndGroup(FilterExpressionList.newBuilder()
.addExpressions(FilterExpression.newBuilder()
.setFilter(Filter.newBuilder()
.setFieldName("platform")
.setStringFilter(Filter.StringFilter.newBuilder()
.setMatchType(Filter.StringFilter.MatchType.EXACT)
.setValue("Android"))))
.addExpressions(FilterExpression.newBuilder()
.setFilter(Filter.newBuilder()
.setFieldName("eventName")
.setStringFilter(Filter.StringFilter.newBuilder()
.setMatchType(Filter.StringFilter.MatchType.EXACT)
.setValue("in_app_purchase"))))))
.setMetricFilter(FilterExpression.newBuilder()
.setFilter(Filter.newBuilder()
.setFieldName("sessions")
.setNumericFilter(Filter.NumericFilter.newBuilder()
.setOperation(Filter.NumericFilter.Operation.GREATER_THAN)
.setValue(NumericValue.newBuilder()
.setInt64Value(1000)))))
.build();
I am trying to use the Rest.patch call in CodenameOne but I am getting nothing back. If I use a REST client like ARC I get a response code of 200 and I can see the change has been made.
The Network Monitor in the CN1 Simulator shows the request being sent but shows no reply either.
Here is the code I use in CN1, Rest.post and Rest.get work well elsewhere in the code, it is Rest.patch that I am having a problem with?
bodyString= "{\"Exported\":\"1\"," +
"\"Notes\":\"Order sent\"}";
Response<Map> jsonData = Rest.patch(URL + "Orders(%27" + orderNumber + "%27)").
jsonContent().
header("Authorization", authorisation).
header("Alias", alias).
body(bodyString).
getAsJsonMap();
int responseCode = jsonData.getResponseCode();
If I send a Rest.put or Rest.post request instead, I get a 404 error, this is from either ARC or CN1.
I want to speak some text; I can get the audio-file(mp3) from google translate tts if I enter a properly formatted url in the browser.
But if I try to createSound it, I only see a 404-error in firebug.
I use this, but it fails:
soundManager.createSound(
{id:'testsound',
autoLoad:true,
url:'http://translate.google.com/translate_tts?ie=UTF-8&tl=da&q=testing'}
);
I have pre-fetched the fixed voiceprompts with wget, so they are as local mp3-files on the same webserver as the page. But I would like to say a dynamic prompt.
I see this was asked long time ago, but I have come to a similar issue, and I was able to make it work for Chrome and Firefox, but with the Audio Tag.
Here is the demo page I have made
http://jsfiddle.net/royriojas/SE6ET/
here is the code that made the trick for me...
var sayIt;
function createSayIt() {
// Tiny trick to make the request to google actually work!, they deny the request if it comes from a page but somehow it works when the function is inside this iframe!
//create an iframe without setting the src attribute
var iframe = document.createElement('iframe');
// don't know if the attribute is required, but it was on the codepen page where this code worked, so I just put this here. Might be not needed.
iframe.setAttribute('sandbox', 'allow-scripts allow-same-origin allow-pointer-lock');
// hide the iframe... cause you know, it is ugly letting iframes be visible around...
iframe.setAttribute('class', 'hidden-iframe')
// append it to the body
document.body.appendChild(iframe);
// obtain a reference to the contentWindow
var v = iframe.contentWindow;
// parse the sayIt function in this contentWindow scope
// Yeah, I know eval is evil, but its evilness fixed this issue...
v.eval("function sayIt(query, language, cb) { var audio = new Audio(); audio.src = 'http://translate.google.com/translate_tts?ie=utf-8&tl=' + language + '&q=' + encodeURIComponent(query); cb && audio.addEventListener('ended', cb); audio.play();}");
// export it under sayIt variable
sayIt = v.sayIt;
}
I guess that I was able to byPass that restriction. They could potentially fix this hack in the future I don't know. I actually hope they don't...
You can also try to use the Text2Speech HTML5 api, but it is still very young...
IE 11 is not working with this hack, some time in the future I might try to fix it
Even though you see this as a 404 error, you're actually running into a cross-domain restriction.
Some of the response headers from that 404 will also give you a clue of what's going on:
X-Content-Type-Options:nosniff
X-XSS-Protection:1; mode=block
So, you won't be able to do this client-side, as Google does not (and probably will never) allow you to do so.
In order to do this dynamic loading of audio, you need to work around this x-domain restriction by setting up a proxy on your own server, which would download whatever file requested by the end-user from Google's servers (via wget or whatever) and spitting whatever data comes from google.
Code I used to reproduce the issue:
soundManager.setup({
url: 'swf',
onready: function() {
soundManager.createSound({
id:'testsound',
autoLoad:true,
url:'http://translate.google.com/translate_tts?ie=UTF-8&tl=da&q=testing'
});
}
});
Your code should look like this:
soundManager.createSound({
id:'testsound',
autoLoad:true,
url:'/audioproxy.php?ie=UTF-8&tl=da&q=testing' // Same domain!
});
Regards and good luck!
Does anyone have a definitive way to post to a user's wall, using nothing but the .NET Framework, or Silverlight?
Problems deriving from people's attempts have been asked here on SO, but I cannot find a full, clear explanation of the Graph API spec and a simple example using WebClient or some similar class from System.Net.
Do I have to send all feed item properties as parameters in the query string? Can I construct a JSON object to represent the feed item and send that (with the access token as the only parameter)?
I expect its no more than a 5 line code snippet, else, point me at the spec in the FB docs.
Thanks for your help,
Luke
This is taken from how we post to a user's wall. We place the data for the post in the request body (I think we found this to be more reliable than including all the parameters in the query part of the request), it has the same format as a URL encoded query string.
I agree that the documentation is rather poor at explaining how to interact with a lot of resources. Typically I look at the documentation for information on fields and connections, then work with the Graph API Explorer to understand how the request needs to be constructed. Once I've got that down it's pretty easy to implement in C# or whatever. The only SDK I use is Facebook's Javascript SDK. I've found the others (especially 3rd party) are more complicated, buggy, or broken than rolling my own.
private void PostStatus (string accessToken, string userId)
{
UriBuilder address = new UriBuilder ();
address.Scheme = "https";
address.Host = "graph.facebook.com";
address.Path = userId + "/feed";
address.Query = "access_token=" + accessToken;
StringBuilder data = new StringBuilder ();
data.Append ("caption=" + HttpUtility.UrlEncodeUnicode ("Set by app to describe the app."));
data.Append ("&link=" + HttpUtility.UrlEncodeUnicode ("http://example.com/some_resource_to_go_to_when_clicked"));
data.Append ("&description=" + HttpUtility.UrlEncodeUnicode ("Message set by user."));
data.Append ("&name=" + HttpUtility.UrlEncodeUnicode ("App. name"));
data.Append ("&picture=" + HttpUtility.UrlEncodeUnicode ("http://example.com/image.jpg"));
WebClient client = new WebClient ();
string response = client.UploadString (address.ToString (), data.ToString ());
}
I don't know much about .net or silverlight, but the facebook api works with simple http requests.
All the different sdks (with the exception of the javascript one) are mainly just wrappers for the http requests with the "feature" of adding the access token to all requests.
Not in all requests the parameters are sent as querystring, in some POST requests you need to send them in the request body (application/x-www-form-urlencoded), and you can not send the data as json.
If the C# sdk is not to your liking, you can simply create one for your exact needs.
As I wrote, you just need to wrap the requests, and you can of course have a method that will get a json as parameter and will break it to the different parameters to be sent along with the request.
I would point you to the facebook documentation but you haven't asked anything specific so there's nothing to point you to except for the landing page.
I am trying to use HTTP to POST a file to an outside API from within a grails service. I've installed the rest plugin and I'm using code like the following:
def theFile = new File("/tmp/blah.txt")
def postBody = [myFile: theFile, foo:'bar']
withHttp(uri: "http://picard:8080/breeze/project/acceptFile") {
def html = post(body: postBody, requestContentType: URLENC)
}
The post works, however, the 'myFile' param appears to be a string rather than an actual file. I have not had any success trying to google for things like "how to post a file in grails" since most of the results end up dealing with handling an uploaded file from a form.
I think I'm using the right requestContentType, but I might have missed something in the documentation.
POSTing a file is not as simple as what you have included in your question (sadly). Also, it depends on what the API you are calling is expecting, e.g. some API expect files as base64 encoded text, while others accept them as mime-multipart.
Since you are using the rest plugin, as far as I can recall it uses the Apache HttpClient, I think this link should provide enough info to get you started (assuming you are dealing with mime-multipart). It shouldn't be too hard to change it around to work with your API and perhaps make it a bit 'groovy-ier'
