I'm working on an integration and need to upload files to an API. The API documentation says to "
Send your file to
POST /pendingfiles.json
using the FORM field
file
"
I tried using tRestClient, but when you select FORM, it sets the content-type as "application/x-www-form-urlencoded". The API doesn't accept that; it has to be multipart/form-data.
I tried using tFileFetch and set the Upload File parameter to True and passed in teh File parameters Name = "file", File = filePath, etc. This actually worked, but I got an error because the response from the API was a 201: Created. Apparently, tFileFetch only considers a 200: OK as an acceptable response.
I tried following this post that suggests customizing tRestClient so that it will accept a multipart form, but I couldn't get the parameter named correctly (form field has to be file) to make it work.
https://community.talend.com/t5/Design-and-Development/tRestClient-MIME-Multipart-Form-Data-POST-to-... This post explained the problem that tFileFetch only allows a 200 OK response.
https://community.talend.com/t5/Design-and-Development/resolved-Upload-file-to-server-that-returns-o... After the last post, I created a new version of tFileFetch and adjusted the accepted responses to 200 OK and 201 Created. It successfully posted the file and gave a correct response.
But now, I need to be able to parse the response to get the file token. When the file successfully uploads, I get a temporary file token that I can then use to attach it to another object in the system. So I have to be able to parse the response to get that file, otherwise it's no good to me.
So I either need to figure out how to adjust tFileFetch so that the response can be sent out as a row or I need to find another way of uploading the file.
I'm not a developer and only understand the basics in Java programming. Any suggestions or help would be greatly appreciated.
Unfortunately it is not supported directly in tRESTClient,
please vote for
https://jira.talendforge.org/browse/TESB-12065 I guess in meantime any HTTP client that can post multipart payloads can be used in tJavaFlex, Apache HTTPClient or CXF, I can prototype the code for the latter option if it can be of interest
