[go-nuts] Re: How can I get the last followed URL use http.Client on 302 Redirections?
Hi Dave, I haven't made it clear on the first post, sorry, I am talking about the behavior of Go's net/http.Client, so there are no browsers involved. Go's net/http.Client will do redirections transparently for user, but there are no exposed way of get the redirected url. see https://play.golang.org/p/jLlKR3yjWSw , that explains what I want to achieve.

Found a hacky solution, https://play.golang.org/p/jLlKR3yjWSw
Any better ideas?
var client = {
CheckRedirect: setFollowURL,
}
func setFollowURL(req *http.Request, via []*http.Request) error {
via[0].URL = req.URL
if len(via) >= 10 {
return errors.New("stopped after 10 redirects")
}
return nil

Thank you all! But I still don't quite understand why the rule does not apply to the first case? var a2 u = a1 x ---> a1 T ---> u V ---> uint64 V and T has the identical underlying types (ie, uint64) and V is not a named type (literal) . which part did I misunderstand?

[go-nuts] question about func type
package main
type u uint64
type f func(int)
func g(x int) {
}
func main() {
var a1 uint64 = 1000
var a2 u = a1 //why this is not OK
var f1 func(int) = g
var f2 f = f1 //while this is allowed?
f2(1)
}
f1's type is func(int), and f2's type is main.f, they are different types,
does implicit conversion happen here?

[go-nuts] context example and http.Request
I am trying to understand Context by reading https://blog.golang.org/context
the code in https://blog.golang.org/context/google/google.go uses transport.
CancelRequest
Since http.Request now (I am using go 1.7.3) has context support now,
I think the code can be simpler now. This is my version of Search:
https://play.golang.org/p/EaHrbogwM9
// Search sends query to Google search and returns the results. func
Search(ctx context.Context, query string) (Results, error) { // Prepare the
Google Search API request. req, err := http.NewRequest("GET",
"https://ajax.googleapis.com/ajax/services/search/web?v=1.0;, nil) if err
!= nil { return nil, err } q := req.URL.Query() q.Set("q", query) // If ctx
is carrying the user IP address, forward it to the server. // Google APIs
use the user IP to distinguish server-initiated requests // from end-user
requests. if userIP, ok := userip.FromContext(ctx); ok { q.Set("userip",
userIP.String()) } req.URL.RawQuery = q.Encode() // Issue the HTTP request
and handle the response. The httpDo function // cancels the request if
ctx.Done is closed. var results Results client := {} req =
req.WithContext(ctx) resp, err := client.Do(req) if err != nil { return
nil, err } defer resp.Body.Close() // Parse the JSON search result. //
https://developers.google.com/web-search/docs/#fonje var data struct {
ResponseData struct { Results []struct { TitleNoFormatting string URL
string } } } if err := json.NewDecoder(resp.Body).Decode(); err != nil
{ return nil, err } for _, res := range data.ResponseData.Results { results
= append(results, Result{Title: res.TitleNoFormatting, URL: res.URL}) }
return results, nil }
But it does not work correctly, first search after `go run server.go`
curl 'http://localhost:8080/search?q=golang=1s'
will give `context deadline exceeded`
but after that repeated searches will not return context deadline.
what's wrong?

Re: [go-nuts] Re: SimpleHttpServer built into go toolchain?
But static binary is way bigger than 10loc snippet, if I compile it to binary which is 6.7 megabytes in size on my laptop, and then scp to my server, it takes 10 minutes to upload meanwhile I can not do anything on the server because my network is saturated during uploading. The case with SimpleHTTPServer is certainly not a production usage. Actually We built a server using net/http which handle 30 billion requests per day without any problems, and we use http.ServeContent for serivng static files. net/http is really good for us and we don't use nginx all. We just use LVS plus six backend servers. With regard to "production ready", someone suggests not using Go's tls: https://github.com/golang/go/issues/17053#issuecomment-246834654. I think It's kind of FUD.Not only do we use Go's https, we used it happyily and believe Go team can respond quickly to any possible security problems.

[go-nuts] SimpleHttpServer built into go toolchain?
One thing that I really like about python is this one command line to serve static files: python -m SimpleHTTPServer This is very convenient. Now I just want to use Go to do the same thing, I have to copy the snippet from https://github.com/golang/go/wiki/HttpStaticFiles and go run it. Since Go is battery included and http is part of its core library, why not just build it into the Go toolchain, So every time I want to serve static files, I can fire up go like this: go tool http /usr/share/doc go tool http --addr=: /usr/share/doc -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.

[go-nuts] why this code deadlocks?
var wg sync.WaitGroup
ints := make(chan int, 1)
done := make(chan bool)
go func() {
for i := 0; i < 3; i++ {
ints <- i
}
close(ints)
}()
f := func() {
wg.Add(1)
defer wg.Done()
for {
i, ok := <-ints
if !ok {
done <- true
return
}
}
}
exit:
for {
select {
case <-done:
break exit
default:
f()
}
}
wg.Wait()
