Compiler changes:
* Change map assignment to use mapassign and assign value directly.
* Change string iteration to use decoderune, faster for ASCII strings.
* Change makeslice to take int, and use makeslice64 for larger values.
* Add new noverflow field to hmap struct used for maps.
Unresolved problems, to be fixed later:
* Commented out test in go/types/sizes_test.go that doesn't compile.
* Commented out reflect.TestStructOf test for padding after zero-sized field.
Reviewed-on: https://go-review.googlesource.com/35231
gotools/:
Updates for Go 1.8rc1.
* Makefile.am (go_cmd_go_files): Add bug.go.
(s-zdefaultcc): Write defaultPkgConfig.
* Makefile.in: Rebuild.

Package http provides HTTP client and server implementations.
|
|
|
|
Get, Head, Post, and PostForm make HTTP (or HTTPS) requests:
|
|
|
|
resp, err := http.Get("http://example.com/")
|
|
...
|
|
resp, err := http.Post("http://example.com/upload", "image/jpeg", &buf)
|
|
...
|
|
resp, err := http.PostForm("http://example.com/form",
|
|
url.Values{"key": {"Value"}, "id": {"123"}})
|
|
|
|
The client must close the response body when finished with it:
|
|
|
|
resp, err := http.Get("http://example.com/")
|
|
if err != nil {
|
|
// handle error
|
|
}
|
|
defer resp.Body.Close()
|
|
body, err := ioutil.ReadAll(resp.Body)
|
|
// ...
|
|
|
|
For control over HTTP client headers, redirect policy, and other
|
|
settings, create a Client:
|
|
|
|
client := &http.Client{
|
|
CheckRedirect: redirectPolicyFunc,
|
|
}
|
|
|
|
resp, err := client.Get("http://example.com")
|
|
// ...
|
|
|
|
req, err := http.NewRequest("GET", "http://example.com", nil)
|
|
// ...
|
|
req.Header.Add("If-None-Match", `W/"wyzzy"`)
|
|
resp, err := client.Do(req)
|
|
// ...
|
|
|
|
For control over proxies, TLS configuration, keep-alives,
|
|
compression, and other settings, create a Transport:
|
|
|
|
tr := &http.Transport{
|
|
MaxIdleConns: 10,
|
|
IdleConnTimeout: 30 * time.Second,
|
|
DisableCompression: true,
|
|
}
|
|
client := &http.Client{Transport: tr}
|
|
resp, err := client.Get("https://example.com")
|
|
|
|
Clients and Transports are safe for concurrent use by multiple
|
|
goroutines and for efficiency should only be created once and re-used.
|
|
|
|
ListenAndServe starts an HTTP server with a given address and handler.
|
|
The handler is usually nil, which means to use DefaultServeMux.
|
|
Handle and HandleFunc add handlers to DefaultServeMux:
|
|
|
|
http.Handle("/foo", fooHandler)
|
|
|
|
http.HandleFunc("/bar", func(w http.ResponseWriter, r *http.Request) {
|
|
fmt.Fprintf(w, "Hello, %q", html.EscapeString(r.URL.Path))
|
|
})
|
|
|
|
log.Fatal(http.ListenAndServe(":8080", nil))
|
|
|
|
More control over the server's behavior is available by creating a
|
|
custom Server:
|
|
|
|
s := &http.Server{
|
|
Addr: ":8080",
|
|
Handler: myHandler,
|
|
ReadTimeout: 10 * time.Second,
|
|
WriteTimeout: 10 * time.Second,
|
|
MaxHeaderBytes: 1 << 20,
|
|
}
|
|
log.Fatal(s.ListenAndServe())
|
|
|
|
Starting with Go 1.6, the http package has transparent support for the
|
|
HTTP/2 protocol when using HTTPS. Programs that must disable HTTP/2
|
|
can do so by setting Transport.TLSNextProto (for clients) or
|
|
Server.TLSNextProto (for servers) to a non-nil, empty
|
|
map. Alternatively, the following GODEBUG environment variables are
|
|
currently supported:
|
|
|
|
GODEBUG=http2client=0 # disable HTTP/2 client support
|
|
GODEBUG=http2server=0 # disable HTTP/2 server support
|
|
GODEBUG=http2debug=1 # enable verbose HTTP/2 debug logs
|
|
GODEBUG=http2debug=2 # ... even more verbose, with frame dumps
|
|
|
|
The GODEBUG variables are not covered by Go's API compatibility
|
|
promise. Please report any issues before disabling HTTP/2
|
|
support: https://golang.org/s/http2bug
|
|
|
|
The http package's Transport and Server both automatically enable
|
|
HTTP/2 support for simple configurations. To enable HTTP/2 for more
|
|
complex configurations, to use lower-level HTTP/2 features, or to use
|
|
a newer version of Go's http2 package, import "golang.org/x/net/http2"
|
|
directly and use its ConfigureTransport and/or ConfigureServer
|
|
functions. Manually configuring HTTP/2 via the golang.org/x/net/http2
|
|
package takes precedence over the net/http package's built-in HTTP/2
|
|
support.
