英文:
golang mux HandleFunc always 404
问题
我尝试使用mux来处理HTTP请求，而不是使用net/http中的标准HandleFunc，因为有一些原因。在使用http时它可以工作，但在使用mux时却不能。
import (
_ "github.com/go-sql-driver/mysql"
"github.com/gorilla/mux"
_ "io/ioutil"
"net/http"
)
func init() {
mx := mux.NewRouter()
// 创建一个投票
mx.HandleFunc("/poll", pollCreate)
mx.HandleFunc("/poll/{id}", loadPoll)
mx.HandleFunc("/poll/vote", castVote)
http.ListenAndServe(":8080", mx)
}
发送以下POST请求：
localhost:8080/poll
结果为：
INFO 2015-06-02 16:23:12,219 module.py:718] default: "POST /poll HTTP/1.1" 404 19
英文:
I try to handle HTTP request using mux instead of standart HandleFunc from net/http, because of reasons. With http it used to work, with mux it doesnt.
import (
_ "github.com/go-sql-driver/mysql"
"github.com/gorilla/mux"
_ "io/ioutil"
"net/http"
)
func init() {
mx := mux.NewRouter()
//create a poll
mx.HandleFunc("/poll", pollCreate)
mx.HandleFunc("/poll/{id}", loadPoll)
mx.HandleFunc("/poll/vote", castVote)
http.ListenAndServe(":8080", mx)
}
The following POST request
localhost:8080/poll
Results in:
INFO 2015-06-02 16:23:12,219 module.py:718] default: "POST /poll HTTP/1.1" 404 19

找到解决方案。
将
http.ListenAndServe(":8080", mx)
改为
http.Handle("/", mx)
英文:
Found solution.
Change
http.ListenAndServe(":8080", mx)
To
http.Handle("/", mx)

你忘记添加默认处理程序了。最好将方法与处理程序一起保留。
import (
_ "github.com/go-sql-driver/mysql"
"github.com/gorilla/mux"
_ "io/ioutil"
"net/http"
)
func init() {
mx := mux.NewRouter()
// 创建一个投票
mx.Path("/").HandlerFunc(indexHandler)
mx.PathPrefix("/poll").Handler(pollCreate).Method("POST")
mx.PathPrefix("/poll/{id}").Handler(loadPoll)
mx.PathPrefix("/poll/vote").Handler(castVote)
http.ListenAndServe(":8080", mx)
}
英文:
You forgot to add the default handler. It's always better to keep the method along with the handlers.
import (
_ "github.com/go-sql-driver/mysql"
"github.com/gorilla/mux"
_ "io/ioutil"
"net/http"
)
func init() {
mx := mux.NewRouter()
//create a poll
mx.Path("/").HandlerFunc(indexHandler)
mx.PathPrefix("/poll", pollCreate).Method("POST)
mx.PathPrefix("/poll/{id}", loadPoll)
mx.PathPrefix("/poll/vote", castVote)
http.ListenAndServe(":8080", mx)
}
