Upload a file via wininet with a POST

[jmsalvador]

Hi Team,

we are using the Dropbox REST API with OAuth2.
When attempting to upload a file I don't know where to put the file contents using the wininet for http way.

In the docs there is just a curl example

curl -X POST https://content.dropboxapi.com/2/files/upload \
    --header "Authorization: Bearer 

" \
    --header "Dropbox-API-Arg: {\"path\": \"/Homework/math/Matrices.txt\",\"mode\": \"add\",\"autorename\": true,\"mute\": false}" \
    --header "Content-Type: application/octet-stream" \
    --data-binary @local_file.txt

but I don't understand how to put the contents file.

I see the 3 headers like in the example but what about the file ?.

data-binary is put in the body ?

or in the header ?

and how ?

I used the postman tool to reproduce the upload I was successful. The problem is that the postman put the file in the body in a binary way selecting the file with a explorer but I cannot see how and where to put it using HttpSendRequest with a POST verb.

Any suggestion to do it ?

Thanks in advance

The /2/files/upload endpoint is a "content-upload" style endpoint, so it does expect the file data for the upload in the request body. That is what curl's "--data-binary" does. (I.e., in the example, that's how you specify what data or file curl should use for the request body.)

I can't offer support for and don't have a sample for WinINet/HttpSendRequest specifically unfortunately though, so you'll need to refer to the documentation for that for instructions on how to configure a request using that with the desired data in the body.
