How to send double quote in -d parameter for curl.exe?

How can I send a double quote char using curl.exe in the -d parameter. I don't want to URL encode the double quote. Since the -d data needs to be surrounded in double quotes, I cannot seem to get it to work.

Or is there another flag for curl.exe that tells it to use a files contents for the whole form post data?

Old question but I liked none of the solutions (actually the -d @filename would have been fine but it wasn't working for me). So after reading the doc (https://curl.se/docs/manpage.html) here is what I ended up using:

echo '{ "a": 1, "b": 2 }' | curl -H "Content-Type: application/json" -d "@-" http://localhost:8080

If you are doing this in Powershell, you will need to quote the whole text block with single quotes and still escape the quotes. i.e. -d '{\"param\":\"value\"}'

Tested on Win11 VSCode Powershell 7 terminal

You can surround the data with single quotes and use double quotes inside.

Example in PowerShell

curl.exe https://httpbin.org/anything `
    -H 'Content-Type: application/json' `
    -d '{ "this": "is proper json" }'.Replace('"', '""')

Please note that cURL is built into Windows 10, but PowerShell shadows it with an alias, so you have to use curl.exe

There is something called dollar slashy string.

def cmd = $/ curl -d '{"param":"value"}' -X POST https://example.com/service /$
sh cmd

My curl.exe works with this form:

-d "{\"param\":\"value\"}"

i.e. doublequotes around data, and doublequotes masked with backslash inside

For the escaping of double quote question, I'm finding that tripling the doublequotes works from the shell:

curl -d {"""foo""":"""bar"""}

while doubling the doublequotes works from within a batch file:

curl -d {""foo"":""bar""}

Which is quite annoying for testing in the shell first.

You can most certainly escape double quotes. How you do that depends on your operating system and shell, which you fail to specify. On Windows, you'd use the ^ as the escape character.

You can also do this:

curl [...] -d @filename

...which reads post data from a file called filename.

Google and/or man is your friend.
