I wrote a demo, but I found that the response body is empty ,For example, if
I add this plugin to a.com, and I request a.com, the plugin will request b.com
and do the processing, now the processing is successful but there is no
response content from a.com.
```bash
package plugins
import (
"encoding/json"
"fmt"
pkgHTTP "github.com/apache/apisix-go-plugin-runner/pkg/http"
"github.com/apache/apisix-go-plugin-runner/pkg/log"
"github.com/apache/apisix-go-plugin-runner/pkg/plugin"
"github.com/sirupsen/logrus"
"net/http"
"time"
)
func init() {
err := plugin.RegisterPlugin(&ForwardAuth{})
if err != nil {
log.Fatalf("failed to register plugin ForwardAuth: %s", err)
}
}
// ForwardAuth is a demo to show how to return data directly instead of
proxying
// it to the upstream.
type ForwardAuth struct {
}
type ForwardAuthConf struct {
Body string `json:"body"`
}
func (p *ForwardAuth) Name() string {
return "forward-auth"
}
func (p *ForwardAuth) ParseConf(in []byte) (interface{}, error) {
conf := ForwardAuthConf{}
err := json.Unmarshal(in, &conf)
return conf, err
}
func (p *ForwardAuth) Filter(conf interface{}, w http.ResponseWriter, r
pkgHTTP.Request) {
req, err := http.NewRequest("GET", "http://xxx";, nil)
if err != nil {
logrus.Errorf("send request failed err:%v", err)
return
}
//req.Header.Set("Cookie", r.Header().Get("Cookie"))
client := http.Client{
Timeout: 5 * time.Second,
}
resp, err := client.Do(req)
if err != nil {
logrus.Errorf("get response failed err:%v", err)
return
}
if resp == nil {
logrus.Errorf("response is nil")
return
}
defer resp.Body.Close()
if len(resp.Header) > 0 {
for k, v := range resp.Header {
if v != nil {
w.Header().Set(k, v[0])
}
}
}
w.Header().Add("X-Resp-A6-Runner", "Go")
return
}
```
not use plugin
after use pulgin
