Grails Form POST with missing params when form Content
I've a controller action where a third party application posts data, the problem is that the POST request params are empty, this is due to POST Content-Type = 'text'. If I simulate (with Chrome Rest Console plugin) the same POST with Content-Type = 'application/x-www-form-urlencoded' then the request params are correctly filled.
How can I enable POST data with Content-Type = 'text'?
You can access the raw POST data using
request.reader.text
As far as I can tell (and I might be wrong) grails won't parse this content type, because it ultimately uses HTTPServletRequest , which only parses www-form-urlencoded , as this is the normal way to pass variable values thorugh HTTP.
You can easily emulate the behaviour you desire by using a grails filter, such as this:
class TextRequestFilters {
def filters= {
textRequestFilter(controller: '*', action:'*') {
before = {
if(request.post && request.format == 'text') {
String postBody = request.reader.text
String[] variables = postBody.split('&')
variables.each { String variable ->
String[] parts = variable.split('=')
String key = URLDecoder.decode(parts[0], request.characterEncoding)
String value = URLDecoder.decode(parts[1], request.characterEncoding)
params[key] = value
}
}
}
}
}
}
Notes:
You probably want to exclude asset requests and such from this filter.
Content type should be text/plain , as this is what grails translates to text format out of the box, but I belive you can set this up in Config.groovy .
