How to Post an attachment or an Excel file via cURL

Hello Dear All,

I am trying to post an attachment to a document or upload an excel file by using restful webservices via cURL. However, I could not make it working so far. I believe I am doing something wrong with my xml request which I post. Could you please advise me on the subject?

Here is the command I have sent for uploading excel files, after I logged on successfully to the server:

curl -i -X "POST" -H "accept:application/xml" -H "content-type:multipart/form-data" -H "X-SAP-LogonToken:"%logtok%"" -d "@spreadsheet.xml" http://pvs9060:6405/biprws/raylight/v1/spreadsheets

content of the spreadsheet.xml file as follows:

<content name="attachmentInfos" type="application/xml">

<spreadsheet>

<name>Rests</name>  // this is the file name

<folderId>38370</folderId> // this is the folder ID in BO server

</spreadsheet>

</content>

<external-content name="attachmentContent" content-type="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" filename="C:/.../Rests.xlsx" /external-content>

Same logic applies to attachments as well...

curl -i -X "POST" -H "accept:application/xml" -H "X-SAP-LogonToken:"%logtok%"" -H "content-type:multipart/form-data" -d "@attachment.xml"  http://pvs9060:6405/biprws/raylight/v1/documents/38372/attachments

Content of the attachment xml as follows:

<content name="attachmentInfos" type="application/xml">

      <attachment>

          <name>Attach_text</name>

          <mimeType>text/plain</mimeType>

          <size>123</size>

      </attachment>

                     </content>

    <external-content name="attachmentContent" type="text/plain" filename="C:/../Test.txt"/>

The problem I am facing is with multipart/form-data types. These 2 post commands should in that format, but I just couldnt manage how to put in a right format to send the request.

Here are what I tried:

- Replacing -d with -f

-Sending  xml part with -d @xml  and the file with -f upload=@filename in the same command

-Changed the direction of the slashes in the xml file for the path of the upload file ( slash (/) and backslash(\)  )

What am I missing here? Could you please help on the subject?
