Go中處理POST和PUT等HTTP方法可通過net/http包實現。1. 在單一處理器中通過r.Method判斷方法類型，適用于簡單場景；2. 為不同方法編寫獨立處理器函數并用switch分發(fā)，結構更清晰；3. 推薦在大型應用中使用Gorilla Mux或Gin等路由器，支持按方法精確路由，提升可維護性。
Handling different HTTP methods like POST and PUT in Go is straightforward using the net/http package. You can distinguish between methods inside a handler function by checking the request's Method field, or use more structured approaches like multiplexers or routers for larger applications.
Check Method in a Single Handler
If you're using a basic setup, you can write one handler that responds differently based on the HTTP method:
func handler(w http.ResponseWriter, r *http.Request) {???if r.Method == "POST" {
??????fmt.Fprintf(w, "Handling POST request
")
??????// Handle form data, JSON, etc.
???} else if r.Method == "PUT" {
??????fmt.Fprintf(w, "Handling PUT request
")
??????// Update resource logic here
???} else {
??????http.Error(w, "Method not allowed", http.StatusMethodNotAllowed)
???}
}
This works for simple cases, but becomes messy as endpoints grow.
Use Separate Handlers per Method
A cleaner approach is to define individual functions for each method and route them accordingly:
- Create dedicated handlers: handlePost() and handlePut()
- Register them under the same path with different logic
???if r.Method != "POST" {
??????http.Error(w, "Invalid method", http.StatusMethodNotAllowed)
??????return
???}
???fmt.Fprintf(w, "Created or updated via POST")
} func handlePut(w http.ResponseWriter, r *http.Request) {
???if r.Method != "PUT" {
??????http.Error(w, "Invalid method", http.StatusMethodNotAllowed)
??????return
???}
???fmt.Fprintf(w, "Fully updated via PUT")
}
Then register them:
http.HandleFunc("/resource", func(w http.ResponseWriter, r *http.Request) {???switch r.Method {
??????case "POST":
?????????handlePost(w, r)
??????case "PUT":
?????????handlePut(w, r)
??????default:
?????????http.Error(w, "Method not allowed", http.StatusMethodNotAllowed)
???}
})
Use a Router (Recommended for Larger Apps)
For better scalability, use a third-party router like Gorilla Mux or Gin:
- Gorilla Mux: Allows explicit method routing
- Gin: Lightweight with built-in method handling
Example with Gorilla Mux:
r := mux.NewRouter()r.HandleFunc("/items", createItem).Methods("POST")
r.HandleFunc("/items/{id}", updateItem).Methods("PUT")
This keeps routes clean and method-specific.
Basically, choose the method based on your app size. For small APIs, direct method checks work fine. For anything bigger, go with a router to keep things maintainable.

Golang中使用的空結構{}是什么
Sep 18, 2025 am 05:47 AM
struct{}是Go中無字段的結構體，占用零字節(jié)，常用于無需數據傳遞的場景。它在通道中作信號使用，如goroutine同步；2.用作map的值類型模擬集合，實現高效內存的鍵存在性檢查；3.可定義無狀態(tài)的方法接收器，適用于依賴注入或組織函數。該類型廣泛用于表達控制流與清晰意圖。

Sep 16, 2025 am 04:17 AM
使用$_SERVER['REQUEST_METHOD']可獲取HTTP請求方法，如GET、POST、PUT、DELETE；對于PUT等方法需通過file_get_contents('php://input')讀取原始數據，并可用switch語句處理不同請求類型。
