在此代碼中，我正在嘗試執(zhí)行函數(shù)中存在的 。tmpl.ExecuteTemplate(res, "about.html", d)showAbout()在文件中，我有兩個(gè)函數(shù)。第一個(gè)是，第二個(gè)是。 函數(shù)檢查授權(quán)，授權(quán)成功后，進(jìn)入具有if語(yǔ)句的函數(shù)。handler.goshowAbout()about()about()showAbout()如果數(shù)據(jù)庫(kù)中的 about 字段為空，則應(yīng)執(zhí)行 ，獲取數(shù)據(jù)并將其插入到數(shù)據(jù)庫(kù)中。aboutform.html如果數(shù)據(jù)已成功插入，則顯示消息并返回以在此處顯示數(shù)據(jù)。about.html只有不執(zhí)行。盡管給出了成功消息。about.html關(guān)于.html<section>   <h1>About</h1>   <hr>   <p>{{.Aboutdata}}</p></section>關(guān)于形式.html<form action="/about" method="POST">    <section>        <label>Content</label>        <textarea name="content"></textarea>        <div>            <input type="submit" value="Submit">        </div>    </section></form>數(shù)據(jù)庫(kù)func Insertdata(key, value string) bool {    collection := Connect.Database("webApp3").Collection("data")    filter := bson.M{"email": Account.Email, "password": Account.Password}    update := bson.M{        "$set": bson.M{            key: value,        },    }    _, err := collection.UpdateOne(context.TODO(), filter, update)    return err == nil}處理程序.gofunc showAbout(res http.ResponseWriter, req *http.Request) {    d := struct{ Aboutdata string }{Aboutdata: database.Account.About}    if d.Aboutdata == "" {        tmpl.ExecuteTemplate(res, "aboutform.html", nil)        content := req.FormValue("content")        inserted := database.Insertdata("about", content)        if inserted == true {            fmt.Println("About is successfully inserted")            tmpl.ExecuteTemplate(res, "about.html", d)   // It is not executing the about.html file        } else {            fmt.Println("About is not inserted")        }    } else {        tmpl.ExecuteTemplate(res, "about.html", d)    // Although this same file is executing here.    }}
