 | |
| 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{
 | |
| 		TLSClientConfig:    &tls.Config{RootCAs: pool},
 | |
| 		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())
 | |
