It seems like setStringBody() must be provided by classes using this trait. How about adding it as abstract method to this trait?

        }

        if (!is_resource($body)) {
            throw new InvalidArgumentException('Body must be a stream !');
        }
        if (!stream_is_local($body)) {
            throw new InvalidArgumentException('Body must be a local stream !');
        }

        rewind($body);
        $this->body = $body;

It seems like $body of type resource is incompatible with the declared type string of property $body.
