在单个 HTTP POST 请求中同时传递文件资源和 json 主体

Question

I'm building a REST API and I have an endpoint where I need to pass both a file resource, and a JSON body. Apparently I cannot do it:

You can only select one HTTP request method! You asked for both POST.

I'm getting this error when in cURL request I provide both form field and a body like this:

curl -X POST "http://127.0.0.1/path" -F "resource=@img.jpg" -d "@requestBody.json"

If I want this to work, I need to pass my request body as a form field itself:

curl -X POST "http://127.0.0.1/path" -F "resource=@img.jpg" -F "myRequestBody=@requestBody.json;type=application/json"

The thing is that in order to fetch this down the line, I need to use file_get_contents() function and then json decode the content as well. It's not a nice solution, and it seems a bit slow. Is there a cleaner way to do it?

Answer 1

Depending on how big the file is, you could base64 encode the data and include that in your JSON payload.

Otherwise, you will need to use Content-Type: multipart/form-data .
