Fhir $export custom location - hl7-fhir

For $export operations the HL7 Fhir spec says Content-Location header with a url for subsequent status requests for Response-Success. Has anyone found a way to direct output to a location of their own choosing?
Let's say I'm calling $export as part of a pipeline that generates a custom Url with my own GUID as part of the CDM GenerateSchema (for tracking purposes), I would like to be able to pass a Url to the $export call with that Url. I see $export is a ResourceType of OperationDefinition, which leads me to believe a customization is possible.
OperationDefinition for $export
Right now I'm capturing the Content-Location from the output of the Web Activity and then copying the resultant ndjson files in a For Loop. It would be better to be able to cut out these steps and direct the output.
TIA

Uploading PDF to AWS Lambda via API Gateway mangles the bits...why?

I have deployed an AWS Lambda function, written in Python, and AWS API Gateway structure to cause POST requests to an API endpoint to be redirected to my function. I want to upload a PDF document to my function and have it store the document in a S3 bucket. The problem I have is that the payload of any POST request to my API is being UTF-8 encoded. I don't want that but can't figure out the magic mojo to disable encoding of the request payload.
I am testing using curl, with the following command line:
curl -XPOST https://xxxxxxxxxx.execute-api.us-west-1.amazonaws.com/test -H 'content-type: application/pdf' --data-binary #document.pdf
UPDATE: I just found the following article describing how API Gateway and Lambda support uploading binary data:
https://aws.amazon.com/blogs/compute/handling-binary-data-using-amazon-api-gateway-http-apis/
This article suggests that all of the complexities that I discussed in the initial formation of my question (still provided below) should not be necessary. All I should need to do to upload binary content to my Lambda function is insure that my request includes an appropriate Content-Type header. I was already doing that, but I massaged my Curl command a bit (modified above) to define my request in exactly the way that is done in this article. I still get UTF-8 encoded data and NOT base-64 encoded data. I tried uploading a jpeg file rather than a PDF so I was doing exactly what was done in the article. Still no love. I don't get it. This article demonstrates exactly what I'm doing. But I don't get the result it suggests I should. Ggggrrrr.
ORIGINAL POST:
I am using Terraform to define my deployment. I want to cause the PDF to not be encoded/mangled at all. This is my first time using API Gateway, and I'm obviously missing some bit of config. The one thing I'm doing specifically right now to say that I want incoming payloads to be treated as binary is via the binary_media_types argument to my API definition in Terraform:
resource aws_api_gateway_rest_api proxy {
...
binary_media_types = [
"application/pdf",
"application/octet-stream",
"*/*"
]
This sets the Binary Media Types configuration associated with the API I've defined. I've confirmed via the AWS Console that this setting is having the desired effect...I can see these types in the console. I should need just the first item in the list, but I've added the others while I try to figure out the problem here. By adding that wildcard item, I believe that it shouldn't matter what the incoming Content-Type is...all payloads should be being treated as binary.
The other bit of config that I know about that might be important is the "integration contentHandling property". Here is the key bit of AWS docs that seems to explain all this:
I think the case that applies to me here is the one I've highlighted, per what I say above. This says to me that I shouldn't need to do anything else, per the "unspecified" value in the table for "contentHandling. I've tried setting the "contentHandling" argument on the integration record of my Terraform config, like this:
resource aws_api_gateway_integration proxy {
...
passthrough_behavior = "WHEN_NO_MATCH"
content_handling = "CONVERT_TO_BINARY"
}
I first tried only specifying the content_handling value. I've also tried setting that value to "CONVERT_TO_TEXT", hoping to then get base64-encoded data. Neither of these has any effect. I've tried adding the passthrough_behavior value as shown. I've also tried replacing "WHEN_NO_MATCH" with "WHEN_NO_TEMPLATES". Nothing I do changes the behavior. I haven't been able to figure out where these settings would show up in the AWS console. If I knew they were necessary, I'd explore this further. But I don't think I need to set these.
What am I missing? How can I POST a PDF document to my AWS Lambda function through API Gateway and have the payload of the request not be converted in any way? TIA!
NOTE: I am aware of this Q/A: PDF Uploaded via AWS API Gateway getting corrupted. The answer there doesn't apply to me, as I need to avoid having to form-encode the upload. The client code that will eventually be doing the upload is set in stone and sends a POST request with a payload that is just the bytes of the PDF.

Google Drive API v3 : there isn't any way to get a download url for a google document?

The Google Drive API v2 to v3 migration guide says:
The exportLinks field has been removed from files. To export Google Documents, use the files.export method instead.
I don't want to export (download) the file right away. "files.export" will actually download the file. I want a link to download the file, later. This was possible in v2 by means of the exportLinks.
How can I in v3 accomplish the same? If it is not possible, why was this useful feature removed?
Besides, (similar problem to above) downloadUrl was also removed, and the suggested alternative ("files.get with ?alt=media") downloads the file instead of providing a download link. This means there is no way in v3 to get a public short lived URL for a file?
EDIT:
there is no way in v3 to get a public short lived URL for a file?
For regular files, apparently yes.
This seems to work fine (a public short lived link to the file with its right name and contents):
https://www.googleapis.com/drive/v3/files/ID?alt=media&access_token=TOKEN
For google apps files, no (not even private, as v2 exportLinks used to be).
https://www.googleapis.com/drive/v3/files/ID/exportmimeType=TYPEv&access_token=TOKEN
Similar to regular files, this URL is a short lived link to the file contents, but lacking of its right name.
BTW, I see the API is not behaving consistently: /drive/v3/files/FILEID delivers the right file name, but /drive/v3/files/FILEID/export does not.
I think the API itself should be setting the right Content-Disposition, as it is apparently doing when issuing a /drive/v3/files/FILEID call.
This file naming problem invalidates the workaround to the lack of ExportLinks in v3.
The v2 ExportLinks allowed me to link a file (which is not the same as getting its content right away). Anyone logged in and with the proper permissions was able to access it, and the link didn't needed any access_token, and it wasn't short lived. It was good and useful.
Building a link with a raw API call like /drive/v3/files/FILEID/export (with mandatory access_token) would be an close enough workaround (it is temporary and public, not the same as it was, anyway). However, the naming problem invalidates it.
In v2, regular files have a WebContentLink and google apps files have exportLinks. In v3 exportLinks are gone, and I don't see any suitable alternative to them.
Once you query for your file by id you can use the function getWebContentLink() to get the download link of the file (eg. $file->getWebContentLink() ).
I think you're placing too much emphasis on the word "method".
There is still a link to export a file, it's https://www.googleapis.com/drive/v3/files/fileIdxxxxx/export&mimeType=xxxxx/xxxxx. Make sure you URL encode the mime type.
Eg
https://www.googleapis.com/drive/v3/files/1fGBQ81haNU_nEiC5GITZD3bxT0ppL2LHg-C0ubD4Q_s/export?mimeType=text/csv&access_token=ya29.Gmo0BMvO-pVEPKsiD9j4D-NZVGE91MChRvwOcBSg3cTHt5uAClf-jFxcovQScbO2QQhwHS95eSGW1eQQcK5G1UQ6oI4BFEJJkntEBkgriZ14GbHuvpDL7LT2pKA--WiPuNoDDIuZMm5lWtlr
These links form part of the API, so the expectation is that you've written a client that sends authenticated requests, and deals with the response data. This explains why, if you simply paste the link into a browser without an access_token, it will fail. It also explains why the filename is export, ie. it isn't intended that your client would ever use a filename, but rather it should receive the data as a stream. This SO answer discusses the situation in more detail How to set name of file downloaded from browser?

REST API URL with Directory and File name as Path Variables

I have a requirement to send the folder details in the URL for POST method, some thing like this
http:///{directory}/{filename}
I am using Spring API to create the service. Using #PathVariables to two variables in the URI.
Problem : Directory can have "/" slashes in it.
Now how can I create my API, please help me.
POST http://example.com/api/files/path/to/my/file/filename
Stick a controller on /api/files. Scrape the URL starting after /files. Use that to locate the file.
P.S. This has the potential to be a Very Bad Idea. Make sure you secure the controller to only expose those parts of your filesystem you don't mind random internet strangers to be able to operate on.

Dredd can't find my API documentation, how do i tell it where it is if it's not on my local drive (it's on apiary.io server)

I am using the Dredd tool to test my API (which resides on apiary.io).
Question
I would like to provide dredd with a path to my documentation (it even asks for it), however my API doc is on apiary.io but i don't know the exact url that points to it. What would be the correct way to provide dredd with the API path?
What did work (but not what i'm looking for)
Note: I tried downloading the api to my local drive and providing dredd with a local path to the file (yml or apib) which works fine (yay!), but i would like to avoid keeping a local copy and simply providing dredd with the location of my real API doc which is being maintained on the apiary server.
How do I do this (without first fetching the file to local drive)?
Attempts to solve this that failed
I also read (and tried) on the following topics, they may be relevant but i wasn't successful in resolving the issue
- Using authentication token as environment variable
- Providing the domain provided by apiary.io//settings to dredd
- Providing the in the dredd command
all of these attempts still produces the same result, Dredd has no idea where to find the API document unless i provide a path in my local computer to the file (which i have to download or create manually on my computer first).
Any help is appreciated, Thanks!
If I understand it correctly, you would like to use dredd and feed it using the API description document residing on Apiar.io platform, right?
If so, you should be able to do that simply calling the init command with the right options:
dredd init -r apiary -j apiaryApiKey:privateToken -j apiaryApiName:sasdasdasd
You can find the private token going into the Test section of the target API (you'll find the button on the application header).
Let me know if this solves the problem for you - I'll make sure to propagate this and document it accordingly on our help page
P.S: You can also use your own reporter - in that case, simply omit -r apiary when writing the command line parameters.
You can feed Dredd not only with a path to file on your disk, but also with an URL.
If your API in Apiary is public, the API description document (in this case API Blueprint) should have a public URL. For example, if you go to http://docs.apiblueprintapi.apiary.io/, you can see on the left there is a Download link. Unfortunately, the link is visible only for users who do not have access to the editor of the API, so you can’t see the link if you’re owner of the API. Try to log out from Apiary and the link should appear:
Then you can feed Dredd with the link:
$ dredd 'http://docs.apiblueprintapi.apiary.io/api-description-document' 'http://example.com:8080/api'
I agree this isn’t very intuitive and since you’re not the first one to come up with this, I think we’ll think of some ways how to make it easier.
If your API isn't public then unfortunately there's no way to get the URL as of now. However, you can either use GitHub Sync or Apiary CLI to get the file on your disk in an automated manner.

Tyring to update a URL using Curl on Linux

I am trying to update an ticket and I am trying to do that through Linux. Not sure whether it can be done or not, in the way of searching, I found one blogger sharing, where he/she was also trying to update something
He/She has used the below commands to update the URL.
curl -i -u "script-user:password" -X PUT -d "short_description=Update+me" https:/0005000972
I suspect he/she is trying to update the URL with "Update me".
Is that right? or else Can some one explain what that blogger tried to do??
This is a RESTful request. That is a request using standard HTTP methods (GET, POST, PUT, DELETE) to query a server.
-X PUT specifies the method used
-d "...." specifies the data send to the server
https://... (ill formed in your example) is of course the URL of the target server
Usually, the PUT method is used to replace an existing attribute/value on the server. As the concrete parameters and/or methods available are service dependent, I can only guess here that the intend is to update some attribute named short_description to store the value Update Me (URL encoded -- or more formally x-www-form-urlencoded)
Maybe you should first read a little bit more about those topics, and then, if necessary post an other question describing more in details both the target server and the goal you're trying to achieve on it.
