+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 := io.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.
