How can I make a PUT request to an API framework

Post by dbcbos » Thu Aug 17, 2017 10:13 am

Question: How can I make a PUT request to an URL?

I have done the following:

Code: Select all

   put "Authorization: Basic " & tUsr & tPwd & cr &\
   "Content-Type: application/json" & cr &\ 
   "PUT /_db/key2publish/_api/cursor/13499179 HTTP/1.1" & cr &\
   "Host: localhost:8529" into tHeaders
   set the httpHeaders to tHeaders
   put URL tURL into tContent
tUsr, tPwd, tURL contents are all verified working with Postmen

Content of the libURLLastHTTPHeaders(): (As you can see where there is a GET there should be a PUT)

Code: Select all

GET /_db/key2publish/_api/cursor/13514325 HTTP/1.1
Host: localhost:8529
Accept: */*
User-Agent: LiveCode (Win32)
Authorization: Basic cm9vdDprZXkycHVibGlzaA==
Content-Type: application/json
Response of the API (which is correct GET is not supported for that URL, PUT is):

Code: Select all

{"error":true,"errorMessage":"method not supported","code":405,"errorNum":405}
I am working on Windows 10 and Livecode 8.1.5

405 suggests the server is expecting something other than PUT. Does POST work? Double-check the API docs.

Hello Richard,

Sorry to get with you back so late. Thank you for your answer.

I have used another API call that does not require PUT to solve this issue.

POST also did not work and setting the headers or customheaders did also not work.

I wonder if this is a bug, it does work in the Chrome App Postmen using PUT.

Everytime I manually set the headers I get from the Postmen app they get written back to either POST or GET

You could actually test it yourself by going to this url: https://docs.arangodb.com/3.1/HTTP/AqlQ ... rom-cursor

and download and install arangodb which I am connecting to

Perhaps this helps:

Code: Select all

command buildHeaderPut
   put "Content-Type: application/json" & cr \
         & "Accept: application/json" & cr \
         & "X-HTTP-Method-Override: PUT" & cr  into tHeaders
   put "Authorization: Basic " after tHeaders
   put base64encode(""& ":" & sAccessToken) into tH
   replace cr with "" in tH
   put th after  tHeaders
   set the httpHeaders to tHeaders
end buildHeaderPut

-- update DBdata Tablename, id_field, id_of_record_to_update,data_as_array -returns 0 if success

function wservice_Update ptable,pkey,precord,pdata
   local turl,tjson,tpost,tresp
   put JsonExport(pdata) into tjson
   put textencode(tjson,"UTF8") into tpost
   buildHeaderPut
   put "http://xxx.xxx.xxx.xxx:81/api/v2/bodata/_table/"&ptable&"/"&precord&"?id_field="&pkey into turl
   libUrlSetSSLVerification false
   post tpost to url turl 
   put JsonImport(it) into tresp
   put tresp["resource"][1]["id"] into tanswer
   if tresp["id"] is a number then
      return 0
   else 
      return "error updating db"
   end if
end wservice_Update

dbcbos-

Sorry to come in late to this topic... I don't spend that much time in the forum.

You're using the wrong syntax if you want to issue a PUT. Your syntax of

Code: Select all

put URL tURL into tContent
issues an http GET command, and translates to

Code: Select all

GET url(tURL) ; put it into tContent
instead try

Code: Select all

put tContent into url(tURL)

First of all the code should be like:

Code: Select all

put URL "http://127.0.0.1:8529/_db/key2publish/_api/cursor/13499179"

I just tested on ArangoDB and livecode works very well.
No changes on header, just use POST:

Code: Select all

put "max" into temp["username"]
put "maxp" into temp["password"]
put jsonexport(temp) into myauth
post myAuth to "http://127.0.0.1:8529/_open/auth"
put it
And I get:

Code: Select all

{"jwt":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1MDk2MzA2OTQsImlhdCI6MS41MDcwMzg2OTQ3NDc0NTJlKzYsImlzcyI6ImFyYW5nb2RiIiwicHJlZmVycmVkX3VzZXJuYW1lIjoibWF4In0=.xJkJh45Eh4zPMJhpPCGrQVKl1IDrIs63R4UcoLXlwBc="}

MaxV-

Yes, the authentication transaction uses an http POST command, but other rest endpoints in the api require a PUT. You have indeed confirmed that LC works with arangoDB, but the http syntax for various endpoints differ, i.e., creating a new user is a POST request, granting access is a PUT request, limiting the amount of documents in a query is a PUT request, returning an index is a GET request. All of these should be easily doable in the context of LC code.

I think that the problem is in Arango Documentation. I have problems also with CURL.
Try CouchDB, that is well supported by livecode http://livecode.wikia.com/wiki/CouchDB

CouchDB is indeed well supported by Greg Miller's Daybed library:
https://github.com/madpink/couchdb4livecode

Re curl, allow me to recommend httpie. For quite some time now I've been using httpie as an alternative to curl or wget. It has a much more intuitive (IMO) commandline syntax and is much more powerful (built-in JSON support, for one thing)
https://httpie.org/

...and Postman for exploratory testing of rest APIs from within a browser. Usually my first stop when faced with a new API. And Postman scripts are exportable to curl.

Thank you all for your input.

I have not tested your new solutions. I gave up using the cursor api and thus using PUT, I used normal post requests to get the data by adding a limit/steps implementation to a query. Which worked out great for the solution I was working on.

Wow, can you show some examples?
I'd like to add a guide on the Wiki, or you can do it yourself. :D
