將編碼字符串添加到 http 響應(yīng)似乎用 !F(MISSING) 替換了一些字符。如何防止？輸出：{"encodedText":"M6c8RqL61nMFy%!F(MISSING)hQmciSYrh9ZXgVFVjO"}代碼：package mainimport (    "encoding/json"    "fmt"    "net/http"    "net/url")type EncodeResult struct {    EncodedText string `json:"encodedText"`}func main() {    http.HandleFunc("/encodedString", encodedString)    _ = http.ListenAndServe(":8080", nil)}func encodedString(w http.ResponseWriter, r *http.Request) {    inputString := "M6c8RqL61nMFy/hQmciSYrh9ZXgVFVjO"    er := EncodeResult{url.QueryEscape(inputString)}    response, _ := json.Marshal(er)    w.Header().Set("Content-Type", "application/json")    fmt.Fprintf(w, string(response))}
