在 GoLang 中，我像這樣循環(huán)我的表單數(shù)據(jù)，for key, values := range r.Form {   // range over map    for _, value := range values {    // range over []string        fmt.Println(key, value)    }}我可以像這樣將數(shù)據(jù)打印到終端，但我需要這個(gè)數(shù)據(jù)是一個(gè)字符串，以便我可以從 for 循環(huán)外部訪(fǎng)問(wèn)它。當(dāng)循環(huán)完成時(shí)，我如何將它放在一個(gè)我可以在 for 循環(huán)之外調(diào)用的變量中？我的目標(biāo)是通過(guò)加入這三個(gè)字符串來(lái)構(gòu)建一個(gè) urlvar SearchUrl = "https://api.themoviedb.org/3/search/movie?query="var MovieSearch []string = r.Form["GetSearchKey"]   var apiKey = "&api_key=e2a"UrlBuild := []string {SearchUrl, MovieSearch, apiKey}fmt.Println(UrlBuild) 我收到這個(gè)錯(cuò)誤/main.go:71: cannot use MovieSearch (type []string) as type string in array or slice literalMovieSearch來(lái)自輸入表單。它是搜索關(guān)鍵字。一旦我有了一個(gè)字符串，我就可以將它傳遞給進(jìn)行 api 調(diào)用的函數(shù)。全功能func searchHandler(w http.ResponseWriter, r *http.Request) {  display(w, "search", &Page{Title: "Search"})   fmt.Println("method:", r.Method)         r.ParseForm()        fmt.Println("GetSearchKey:", r.Form["GetSearchKey"])for key, values := range r.Form {   // range over mapfor _, value := range values {    // range over []string    fmt.Println(key, value)  }}var SearchUrl = "https://api.themoviedb.org/3/search/movie?query=" var MovieSearch []string = r.Form["GetSearchKey"]   var apiKey = "&api_key=ewrfwrfwrcwerc"UrlBuild := []string {SearchUrl, MovieSearch, apiKey}fmt.Println(UrlBuild)fmt.Println(reflect.TypeOf(r.Form["GetSearchKey"] ))}錯(cuò)誤來(lái)自這一行，UrlBuild := []string {SearchUrl, MovieSearch, apiKey}
