POST csv/Text file using cURL

Question

How can I send POST request with a csv or a text file to the server running on a localhost using cURL.

I have tried curl -X POST -d @file.csv http://localhost:5000/upload but I get

{ "message": "The browser (or proxy) sent a request that this server could not understand." }

My server is flask_restful API. Thanks a lot in advance.

Answer 1

There are many alternate ways to accomplish this. One way is I have used the following:

curl -F ‘data=@<file_location>’ <URL>

Eg. curl -F [email protected] localhost:5000/h

Your command can also be changed slightly like this

curl -X POST -H 'Content-Type: text/csv' -d @file.csv http://localhost:5000/upload

The above is one of the many ways.It can be sent either as a part of form or data, or multipart, etc. You can refer Medium Post

Curl's default Content-Type is application/x-www-form-urlencoded so your problem is probably that the data you are POSTing is not actually form data. It might work if you set the content type header properly:

-H "Content-Type: text/csv"

Though it does depend on the server.
