what does the writeToFile service do in webmethods? - webmethods

*
Can any one explain me the writeToFile service do in webMethods
*

In webMethods out-of-the-box there is no such service.
There is a service PSUtilities.file:writeToFile commonly used by people from PSUtilities2_x package. It us used to write a string into a file (like name actually suggests).
It requires three input parameters:
userData - actual string to write to file
filename - complete file path (folder+file name)
appendOverwriteFlag - flag indicating whether to overwrite file contents or append string to to end of the existing file
Update: in newer wM versions (checked 9.9+ versions) there are new services:
pub.file:readerToFile
pub.file:streamToFile
pub.file:stringToFile
that can be used to wrote content to file. Please refer to available document ation in "Integration_Server_Built_In_Services_Reference" document for more details on service usage.

differences between get_directory_client and get_subdirectory_client for azure file share

Azure file share Python SDKs have two similar methods get_directory_client and get_subdirectory_client. It seems both are interacting with directories. But do we need two methods to perform the same task?
get_directory_client is to get the root directory, and get_subdirectory_client is to get the subdirectories of the current directory.
As you can see from the document, you must get the ShareClient object first. At this time, you can only call get_directory_client to get the root directory, and then you will get the ShareDirectoryClient object. At this time, if you want to get the subdirectory , You can only call the get_subdirectory_client method.
You can also refer to the description of the file share client to understand the difference:
==========================update======================
connection_string = "<your-connection-string>"
service = ShareServiceClient.from_connection_string(conn_str=connection_string)
share = service.get_share_client("<your-file-share-name>")
my_files = []
for item in share.list_directories_and_files():
my_files.append(item)
if item["is_directory"]:
for item2 in share.get_directory_client(item["name"]).list_directories_and_files():
my_files.append(item)
for item3 in share.get_directory_client(item["name"]).get_subdirectory_client(item2["name"]).list_directories_and_files():
my_files.append(item3)
else:
my_files.append(item)
print(my_files)
You can refer to this official documentation.
Honestly, I find it a bit confusing having to deal with two different methods to do "the same thing". I prefer to instantiate the directory client via the from_connection_string method.
For more information on how to list files from a FileShare, take a look at the following post: "Azure File Share - Recursive Directory Search like os.walk". The approach I reported allows to list files recursively, walking through the directories.

Download a file from Google Drive using google-api-ruby-client

I try to download files from a directory on Google Disk.
The code, mostly copied from official quickstart guide, works fine:
# ... code from official quickstart tutorial...
# Initialize the API
service = Google::Apis::DriveV3::DriveService.new
service.client_options.application_name = APPLICATION_NAME
service.authorization = authorize
# now the real deal
response = service.list_files(q: "'0ByJUN4GMe_2jODVJVVpmRE1VTDg' in parents and trashed != true",
page_size: 100,
fields: 'nextPageToken, files(id, name)')
puts 'Files:'
puts 'No files found' if response.files.empty?
response.files.each do |file|
puts "#{file.name} (#{file.id})"
# content = service.get_file(file.id, download_dest: StringIO.new)
end
The output looks fine:
Files:
k.h264 (0B4D93ILRdf51Sk40UzBoYmZKMTQ)
output_file.h264 (0B4D93ILRdf51V1RGUDFIWFQ5cG8)
test.mp4 (0B4D93ILRdf51dWpoZWdBV3l4WjQ)
test2.mp4 (0B4D93ILRdf51ZmN4ZGlwZjBvR2M)
test3.mp4 (0B4D93ILRdf51ZXo0WnVfdVBjTlk)
12.mp4 (0ByJUN4GMe_2jRzEwS1FWTnVkX00)
01.mp4 (0ByJUN4GMe_2jSlRWVEw4a1gxa2s)
01.mp4 (0ByJUN4GMe_2jOFpPMW9YNjJuY2M)
But once I uncomment content = service.get_file(file.id, download_dest: StringIO.new), I get a lot of errors:
Files:
k.h264 (0B4D93ILRdf51Sk40UzBoYmZKMTQ)
/Users/mvasin/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/google-api-client-0.9.15/lib/google/apis/core/http_command.rb:211:in `check_status': Invalid request (Google::Apis::ClientError)
[...lots of other 'from' stuff...]
from /Users/mvasin/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/google-api-client-0.9.15/generated/google/apis/drive_v3/service.rb:772:in `get_file'
from quickstart.rb:56:in `block in <main>'
from quickstart.rb:54:in `each'
from quickstart.rb:54:in `<main>'
But that's the way it should work according to ruby section in "download files" official tutorial.
I also tried content = service.get_file(file.id, download_dest: "/tmp/#{file.name}"), but it failed with the same set of errors.
UPDATE: Here are my findings. If you start with Google Drive API Ruby quick start tutorial, and want make it download something,
1) change scope to not just let your script read meatadata, but read files contents as well:
SCOPE = Google::Apis::DriveV3::AUTH_DRIVE_METADATA_READONLY
to at least
SCOPE = Google::Apis::DriveV3::AUTH_DRIVE_READONLY
2) Filter out google docs files, because you can't download them this way, you have to convert them. To filer them:
2.1) Add mime_type to fileds set:
response = service.list_files(page_size: 10, fields: 'nextPageToken, files(id, name, mime_type)')
2.2) and in the final loop where you print files' ids and names, put something like
service.get_file(file.id, download_dest: "/your/path/#{file.name}") unless file.mime_type.include? "application/vnd.google-apps"
From the error that you got, it says that your request is invalid. So make sure that your request there are correct. Here is the documentation on how to download files using Ruby(just click the Ruby on the example to view the ruby code.)
Take NOTE: Downloading the file requires the user to have at least
read access. Additionally, your app must be authorized with a
scope
that allows reading of file content.

Storing data in FIWARE Object Storage

I'm building an application that stores files into the FIWARE Object Storage. I don't quite understand what is the correct way of storing files into the storage.
The code python code snippet below taken from the Object Storage - User and Programmers Guide shows 2 ways of doing it:
def store_text(token, auth, container_name, object_name, object_text):
headers = {"X-Auth-Token": token}
# 1. version
#body = '{"mimetype":"text/plain", "metadata":{}, "value" : "' + object_text + '"}'
# 2. version
body = object_text
url = auth + "/" + container_name + "/" + object_name
return swift_request('PUT', url, headers, body)
The 1. version confuses me, because when I first looked at the only Node.js module (repo: fiware-object-storage) that works with Object Storage, it seemed to use 1. version. As the module was making calls to the old (v.1.1) API version instead of the presumably newest (v.2.0), referencing to the python example, not sure if that is an outdated version of doing it or not.
As I played more with the module, realised it didn't work and the code for it was a total mess. So I forked the project and quickly understood that I will need rewrite it form the ground up, taking the above mention python example from the usage guide as an reference. Link to my repo.
As of writing this the only methods that aren't implement is the object storage (PUT) and object fetching (GET).
Had some addition questions about the Object Storage which I sent to fiware-lab-help#lists.fiware.org, but haven't heard anything back so asking them here.
Haven't got much experience with writing API libraries. Should I need to worry about auth token expiring? I presume it is not needed to make a new authentication, every time we interact with storage. The authentication should happen once when server is starting-up (we create a instance) and it internally keeps it. Should I implement some kind of mechanism that refreshes the token?
Does the tenant id change? From the quote below is presume that getting a tenant I just a one time deal, then later you can use it in the config to make less authentication calls.
A valid token is required to access an object store. This section
describes how to get a valid token assuming an identity management
system compatible with OpenStack Keystone is being used. If the
username, password and tenant details are known, only step 3 is
required. source
During the authentication when fetching tenants how should I select the "right" one? For now i'm just taking the first one similar as the example code does.
Is it true that a object storage container belongs to only a single region?
Use only what you call version 2. Ignore your version 1. It is commented out in the example. It should be removed from the documentation.
(1) The token will be valid for some period of time. This could be an hour or a day, depending on the setup. This period of time should be specified in the token that is returned by the authentication service. The token needs to be periodically refreshed.
(2) The tenant id does not change.
(3) Typically only one tenant id is returned. It is possible, however, that you were assigned more than one id, in which case you have to pick which one you are currently using. Containers typically belong to a single tenant and are not shared between tenants.
(4) Containers are typically limited to a single region. This may change in the future when multi-region support for a container is added to Swift.
Solved my troubles and created the NPM module that works with the FIWARE Object Storage: https://github.com/renarsvilnis/fiware-object-storage-ge

How to get custom-resource file after packaging Metro App?

I have a Metro application in which am using different service URLs for receiving the data.For this scenario I want to change service URLs after building my application into a package.I have followed adding resource files into my app as mentioned in MSDN sites and tested by using following code.
var resourceLoader = new Windows.ApplicationModel.Resources.ResourceLoader();
var resourceString = resourceLoader.getString("greeting");
Here am getting greeting resource value string in my app before packaging.After packaging am not able to see my resource files but am able to see default resource files like en-US,fr-FR etc but.
Can anyone suggest some solution to get custom-resource file after packaging?
The way I see it you need to add the resource files before packaging the app... after that's done, you can not additional resources... what you could do is getting the new service url from a service and save it locally as a setting or in your DB
edit: also, resourceLoader.getString("greeting").value; will give you the actual string, or "greeting" in case no resources were found

Not receiving "webViewLink" in response?

After turning on Google Drive API access from the management console and getting my Client ID keys, I followed the sample code (using Python 2.7) and I am able to insert a folder, set the appropriate permissions (type=anyone,role=reader), and insert a text/html type file into the new folder.
However the JSON file resource objects I receive from executing insert on the drive service have no 'webViewLink' field! There are 'webContentLink' and 'selfLink' fields but 'webViewLink', which is necessary for static HTML publishing, seems to be missing.
Most perplexing. If this feature hasn't been turned on yet or if I need to configure my account settings to allow HTML publishing please let me know. Any other help would be most appreciated ;)
The webViewLink property is only returned for public folders, and not the single files inside such folders. You can use that as the base url to construct links to your files.
The WebViewLink file property can be retrieved by doing something like this:
$file = $service->files->get($file_id, array('fields' => 'webViewLink'));
$web_link_view = $file->getWebViewLink();
OR
$sheetsList = $drive_service->files->listFiles([
'fields' => 'files(id, name, webViewLink, webContentLink)',
]);
$web_link_view = $sheetsList->current()->getWebViewLink();
Pay attention that you should load the file specifying which fields you wanna bring with it (In this case, webViewLink). If you don't do that, only id and name will be available.
If you also need to configure file permissions, you can do something like:
$permissions = new \Google_Service_Drive_Permission();
$permissions->setRole('writer');
$permissions->setType('anyone');
$drive_service->permissions->create($file_id, $permissions);
Possible values for setRole() and setType() can be found here: https://developers.google.com/drive/api/v3/reference/permissions/create
