使用spray / scala从post请求中获取表单参数

Question

I'm really new with all this Scala/Spray. With some testing I was able to get parameters from a Get request using the parameters function. However I'm trying to fetch some parameters sent from a POST request on the body of the request. It seems like parameters function is unable to fetch those values.

As an example, I'm trying to get this values "name=john&lastname=smith" from the post request body. What is the best option to get these values?

Thank you

You could use [Form-Field-Filters] to extract parameters from POSTs

Answer 2

Indeed, the parameters directive only handles things actually in the query-string and not parameters in the body of the request. To get things out of the body, you'll need to use the content directive and then unmarshal the content.

This spray-user thread may be helpful, as it includes some unmarshalling code doing precisely what you're looking for.

截至最近的Spray版本，您需要使用Unmarshaller for FormData 。
