I am using the Java API for uploading files to Rackspace Cloud. I am trying to figure out how to set the header "Access-Control-Allow-Origin" on the files that I am uploading. I found another link that talks about setting this header using Python Binding here:
Setting Access-Control-Allow-Origin (CORS) in the Rackspace Cloud Files Python API
Is there a similar API with Java Binding as well? I can't seem to find it.
Thanks!
I'm not much of a Java guy, but per this it looks like metadata needs to be set on your containers, with a key of X-Container-Meta-Access-Control-Allow-Origin, and a value of a space separated list of allowed origins.
Thus you need to use whatever function is used to set container metadata for the jclouds API.
It appears that this could be done on creation like so (based on adaptation of this code):
CreateContainerOptions options = CreateContainerOptions.Builder
.withMetadata(ImmutableMap.of("Access-Control-Allow-Origin", "*"));
swift.getApi().createContainer(Constants.CONTAINER, options);
Looking through the docs, I found the following function in org.jclouds.openstack.swift.CommonSwiftClient:
boolean setContainerMetadata(String container,
Map<String,String> containerMetadata)
It therefore looks like you should be able to do what you're looking for with something like the following:
swift.getApi().setContainerMetadata(container, ImmutableMap.of("Access-Control-Allow-Origin", "*"));

Currently using this method as a legacy method.
this.prefService = Components
.classes["#mozilla.org/preferences-service;1"]
.getService(Components.interfaces.nsIPrefService);
this.prefBranch = this.prefService.getBranch(root);
but i did not get a complete idea about how to use this in the webextension environment thunderbird .any api in order to use this feature ?
I solved my issue, by using Web Extension experiment.
Implemented the same legacy extension function with the Web Extension Experiment Specification and that solved my need at this moment.
the link mentioned below.

I think you can use the storage.local API (see documentation, it seems to work the same for Firefox and Thunderbird). This allows you to store data related to your add-on with something like:
let settingItem = browser.storage.local.set(
keys // object
)
and to retrieve or remove it after that (see available methods).
I have an HTTP triggered, NodeJs Azure Function, and I'm looking to remove the "X-Powered-By" header from my response, but have found no way to do so.
I've tried adding both this and this azure site extensions, but neither has worked for me,
Setting the response header manually, i.e. res.headers = { ['x-powered-by']: null } is ineffective.
Based on the comments made on this github issue: https://github.com/Azure/Azure-Functions/issues/290 it would seem that using either extension should have removed the headers you wanted.
Modifying the response headers will likely won't work as they are probably added further down the pipeline by the function host and not overridable, see:
Access Azure Function runtime settings
Azure functions recently removed the x-aspnet-version header, further removal of other headers is tracked as part of the azure-webjobs-script-sdk here
You should leave a comment on the github issue and you can further discuss with the team working on this.
There is an extension called Remove Custom Headers that works for Web Apps but not for functions that have their own resource group. So, what you can do is:
1. Create a regular Web App
2. Create a function and make sure you use the same Hosting Plan as the Web App (do not use Consumption).
3. Once the function is created, install the extension named: "Remove Custom Headers"
4. Restart the function and the headers (Server and X-Powered-By) should disappear.
I have Clarion 9 app that I want to be able to communicate with HTTP servers. I come from PHP background. I have 0 idea on what to do.
What I wish to be able to do:
Parse JSON data and convert QUEUE data to JSON [Done]
Have a global variable like 'baseURL' that points to e.g. http://localhost.com [Done]
Call functions such apiConnection.get('/users') would return me the contents of the page. [I'm stuck here]
apiConnection.post('/users', myQueueData) would POST myQueueData contents.
I tried using winhttp.dll by reading it from LibMaker but it didn't read it. Instead, I'm now using wininet.dll which LibMaker successfully created a .lib file for it.
I'm currently using the PROTOTYPE procedures from this code on GitHub https://gist.github.com/ddur/34033ed1392cdce1253c
What I did was include them like:
SimpleApi.clw
PROGRAM
INCLUDE('winInet.equ')
ApiLog QUEUE, PRE(log)
LogTitle STRING(10)
LogMessage STRING(50)
END
MAP
INCLUDE('winInetMap.clw')
END
INCLUDE('equates.clw'),ONCE
INCLUDE('DreamyConnection.inc'),ONCE
ApiConnection DreamyConnection
CODE
IF DreamyConnection.initiateConnection('http://localhost')
ELSE
log:LogTitle = 'Info'
log:LogMessage = 'Failed'
ADD(apiLog)
END
But the buffer that winInet's that uses always returns 0.
I have created a GitHub repository https://github.com/spacemudd/clarion-api with all the code to look at.
I'm really lost in this because I can't find proper documentation of Clarion.
I do not want a paid solution.
It kind of depends which version of Clarion you have.
Starting around v9 they added ClaRunExt which provides this kind of functionality via .NET Interop.
From the help:
Use HTTP or HTTPS to download web pages, or any other type of file. You can also post form data to web servers. Very easy way to send HTTP web requests (and receive responses) to Web Servers, REST Web Services, or standard Web Services, with the most commonly used HTTP verbs; POST, GET, PUT, and DELETE.
Otherwise, search the LibSrc\ directory for "http" and you will get an idea of what is already there. abapi.inc for example, appears to provide a wrapper around wininet.lib.
I'm trying to access the result of a GET request provided by Azure, as shown in the example : https://msdn.microsoft.com/sv-se/library/azure/dn820159.aspx
My problem is that the api-version is a mandatory argument, but I have no idea about what to write inside. I'm a bit lost with the Azure Batch documentation, it doesn't seem to be complete.
I found something in an Azure webpage : https://azure.microsoft.com/en-us/documentation/articles/search-api-versions/ and the api-version was api-version=2015-02-28. However, if I try it in my browser, I have this answer : "key":"Reason","value":"The specified api version string is invalid".
Any idea of what I can put inside the api-version parameter ?
Have a look here
As the time of this writing
The version of the Batch API described here is '2016-07-01.3.1', and
using that version is recommended where possible.
Earlier versions include '2016-02-01.3.0', '2015-12-01.2.1',
'2015-11-01.2.1', '2015-06-01.2.0', '2015-03-01.1.1', and
'2014-10-01.1.0'.
So try specifying '2016-07-01.3.1'
I am using the Java jclouds API for access to my Rackspace cloud files account.
I can create and list containers, and upload objects, but I can't figure out how to get the public links for an uploaded object. (I can see these public links from within the Rackspace control panel, by right-clicking on the object - there are 4 types: HTTP, HTTPS, Streaming, iOS Streaming).
The closest I can get is by using object.getInfo() to get the object's metadata. This includes a URI, but this doesn't resemble the public links I find from within the control panel.
Anyone know what I'm doing wrong?
I figured it out...
First, I should get the public URI of the object's container, not from the object.
Then I use a CloudFilesClient object. On the container I need to use getCDNMetadata("containername").getCDNUri()
Here is more information and some sample code to get the specific file CDN address.
For more details you can checkout the Java guide:
https://developer.rackspace.com/docs/cloud-files/quickstart/?lang=java
First get the cloud files api:
CloudFilesApi cloudFilesApi = ContextBuilder.newBuilder("rackspace-cloudfiles-us")
.credentials("{username}", "{apiKey}")
.buildApi(CloudFilesApi.class);
From there you can query the container:
CDNApi cdnApi = cloudFilesApi.getCDNApi("{region}");
CDNContainer cdnContainer = cdnApi.get("{containerName}");
Now with that CDNContainer you can get the specific web address that you need:
URI httpURI = cdnContainer.getUri();
URI httpsURI = cdnContainer.getSslUri();
This will get you the base URI for the container. Now to get the final address for your specific file you will need to append /{"your_file_name.extension"} to the end of the address. For example if my base URI was converted to a URL then to a String it may look like:
http://123456asdf-qwert987653.rackcdn.com/
From here I can get a file with the name example.mp4 with the following address:
http://123456asdf-qwert987653.rackcdn.com/example.mp4
This all assumes that you have already enabled CDN on the container.
