Description

Sets the post fields.
Pass a text, which should be the full data to post in an HTTP POST operation.
The plugin sets the size for you. There is usually not need to call CURL.SetOptionPostFieldSize function to overwrite it.

If you plan to pass a form, maybe check functions like CURL.FormAddKeyValue instead of building post fields yourself.

You can use CURL.SetOptionHTTPHeader to set the content type and other headers.

Using this function is not recommended for more than a few hundred MB of text. If you need more, better stream the data with CURL.OpenInputFile from a file.

If you like to make a PATCH or PUT, you can use either CURL.SetOptionPostFields + CURL.SetOptionCustomRequest or the combination of CURL.SetOptionUpload + CURL.SetInputText. It seems to be bad to use CURL.SetOptionPostFields and CURL.SetOptionUpload since CURL tries to upload, but hasn't got data.

See also COPYPOSTFIELDS option in CURL manual.

Examples

Run a generic POST request for REST or SOAP web service:

# new session
Set Variable [$curl; Value:MBS("CURL.New")]
# use stripe charge API
Set Variable [$result; Value:MBS("CURL.SetOptionURL"; $curl; "https://someURL/service")]
# set user name and password if needed:
Set Variable [$result; Value:MBS("CURL.SetOptionUserName"; $curl; "user name")]
Set Variable [$result; Value:MBS("CURL.SetOptionPassword"; $curl; "password")]
# set some additional headers, which may include custom authorization and content types:
Set Variable [$result; Value:MBS( "CURL.SetOptionHTTPHeader"; $curl; "Authorization: Bearer a92eabb9-76f9-42ee-b280-bcd15cb2e9db"; "Content-Type: application/json" )
# make a post with given content:
Set Variable [$result; Value:MBS("CURL.SetOptionPostFields"; $curl; $json]
# perform
Set Field [CURL Test::Result; MBS("CURL.Perform"; $curl)]
# now check result
Set Field [CURL Test::Text; MBS("CURL.GetResultAsText"; $curl; "UTF8")]
Set Field [CURL Test::header; MBS("CURL.GetDebugMessages"; $curl)]
# cleanup
Set Variable [$result; Value:MBS("CURL.Release"; $curl)]
