I am having issues with urlfetch's timeouts on Google App Engine in Go. The app does not appear to want to take a longer timeout than about 5 seconds (it ignores a longer timeout and times out after its own time).
My code is:
var TimeoutDuration time.Duration = time.Second*30
func Call(c appengine.Context, address string, allowInvalidServerCertificate bool, method string, id interface{}, params []interface{})(map[string]interface{}, error){
data, err := json.Marshal(map[string]interface{}{
"method": method,
"id": id,
"params": params,
})
if err != nil {
return nil, err
}
req, err:=http.NewRequest("POST", address, strings.NewReader(string(data)))
if err!=nil{
return nil, err
}
tr := &urlfetch.Transport{Context: c, Deadline: TimeoutDuration, AllowInvalidServerCertificate: allowInvalidServerCertificate}
resp, err:=tr.RoundTrip(req)
if err != nil {
return nil, err
}
defer resp.Body.Close()
body, err := ioutil.ReadAll(resp.Body)
if err != nil {
return nil, err
}
result := make(map[string]interface{})
err = json.Unmarshal(body, &result)
if err != nil {
return nil, err
}
return result, nil
}
No matter what I try to set TimeoutDuration
to, the app times out after about 5 seconds. How prevent it from doing that? Did I make some error in my code?
