Posting a File to a Web Service

[Jeffrey Ferreira]

Hi List,
in the past i could never get *plus/web/request work with uploading a file.
i can get it to work in postman, curl and powershell....but i cannot get syntax right in pxplus
i'm referring to line 100 .
does anyone know what i'm doing wrong or has used *plus/web/request to post/upload file
i dont want to use a 3rd party utility if i can help it

0040 let RAW_CREDENTIALS$="username:password"
0050 call "*web/base64;ENCODE_STR",RAW_CREDENTIALS$,BASE64_CREDENTIALS$
0060 let EXTRA_HEADERS$="Authorization: Basic "+BASE64_CREDENTIALS$
0070 let MIME_TYPE$="multipart/form-data"
0080 let URI$="https://staging.saberis.com:9000/api/v1/documents/modules/21/upload"
0100 let BODY$="filename=Cleary_Quote.xml"
0110 call "*plus/web/request",URI$,BODY$,RESPONSE$,RESPONSE_HEADER$,MIME_TYPE$,"",EXTRA_HEADERS$


thanks

jeff

Attached is the PVX helper class I use to upload files to APIs

Use it like this :

Code: [Select]

field_name$="Name of the form field the webservice is waiting for"
file_name$="Name of the file to upload : this will be the value of the form field above"
file_content$="File content"
file_mime_type$="MIME type of the file to upload, application/octet-stream by default"
upload=new("http.upload",field_name$,file_name$,file_content$,file_mime_type$)
! // use upload'content_type$ as mime_type in the *plus/web/request
! // use upload'body$() as body in the *plus/web/request

The file_content$ variable should be loaded with a binary read of the file

Code: [Select]

open (hfn,isz=-1) file_name$
file_content$ = rcd(lfo,siz=10000000)
Hope this helps

Jeff,

There is a utility built into PxPlus that will load a variable with the contents of a file:  *tools/readfile.

https://manual.pvxplus.com/PXPLUS/utilities/readfile.htm

Given this all you need to do is change line 100 in your code to something like:

0100 call "*tools/readfile", "Cleary_Quote.xml", Body$

Hi Mike, i tried your method...
of course i know i'm doing something wrong.
but i think it might have something to do with what Stephane said
the api says i have to  reference a field name and a filename

Here is there sample post below.....maybe i have to try sending this filename somewhere..
i'm going to try and find my curl command that worked and attach.

POST /api/v1/documents/modules/17/upload HTTP/1.1
Host: {host}
Authorization: Basic [BASIC_ENCODED_LOGIN_INFORMATION]=
Cache-Control: no-cache
Content-Type:https://forum1.pvxplus.com/Themes/vVide/images/bbc/bold.gif multipart/form-data; boundary=----
WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="filename"; filename="Paradigm.xml"
Content-Type: text/xml
------WebKitFormBoundary7MA4YWxkTrZu0gW--

Here is my curl command that worked

curl -k  -H "Content-Type: multipart/form-data" -H "Authorization: Basic  Base64Credentials" -F file[filename]=@s:\jeff\Cleary_Quote.xml -X POST https://staging.saberis.com:9000/api/v1/documents/modules/21/upload

i'm going to try adding in what Stephane said and see if that helps.

Hi,

i got it to work  with Stephane's helper class.
thank you so much.
at least the response said message queued and i'm pretty sure that means it worked.
i have to read thru Stephane's class now and figure out what on earth he did.
