這不是設置 POST 請求正文的正確方法嗎？data := url.Values{}data.Set("url", "https://www.google.com/")client := http.Client{}r, err := http.NewRequest(http.MethodPost, apiURL, strings.NewReader(data.Encode()))下面的代碼執行時表明請求url param中未發送任何內容POST。package mainimport ( "fmt" "io/ioutil" "net/http" "net/url" "strings")func doAPICall() { // curl -XPOST -d 'url=https://www.google.com/' 'https://cleanuri.com/api/v1/shorten' apiURL := "https://cleanuri.com/api/v1/shorten" data := url.Values{} data.Set("url", "https://www.google.com/") client := http.Client{} r, err := http.NewRequest(http.MethodPost, apiURL, strings.NewReader(data.Encode())) if err != nil { panic(err) } resp, err := client.Do(r) if err != nil { panic(err) } body, err := ioutil.ReadAll(resp.Body) if err != nil { panic(err) } fmt.Println(string(body))}func main() { doAPICall()}輸出：-$ go run .{"error":"API Error: URL is empty"}$

服務器期望 Content-Type 請求標頭具有有效值。
r, err := http.NewRequest(http.MethodPost, apiURL, strings.NewReader(data.Encode()))
if err != nil {
panic(err)
}
r.Header.Set("Content-Type", "application/x-www-form-urlencoded") // <-- add this line
resp, err := client.Do(r)
服務器還支持 JSON 請求體：
r, err := http.NewRequest(http.MethodPost, apiURL, strings.NewReader(`{"url": "https://www.google.com/"}`))
if err != nil {
panic(err)
}
r.Header.Set("Content-Type", "application/json")
resp, err := http.DefaultClient.Do(r)

你可以做這樣的事情
package main
import (
"fmt"
"io/ioutil"
"net/http"
"strings"
)
func main() {
url := "https://cleanuri.com/api/v1/shorten"
payload := strings.NewReader("url=https://www.google.com/")
req, err := http.NewRequest("POST", url, payload)
if err != nil {
fmt.Println(err)
return
}
req.Header.Add("content-type", "application/x-www-form-urlencoded")
req.Header.Add("cache-control", "no-cache")
res, err := http.DefaultClient.Do(req)
if err != nil {
fmt.Println(err)
return
}
defer res.Body.Close()
body, _ := ioutil.ReadAll(res.Body)
fmt.Println(res)
fmt.Println(string(body))
}
