在此代碼中，我有兩條消息。1-第一個是注冊您的帳戶已創(chuàng)建。現(xiàn)在登錄到一個帳戶，然后2-第二個是登錄失敗，即如果電子郵件或密碼不匹配，則給出錯誤消息。我已經(jīng)在文件中調(diào)用了這兩條消息，但是當我運行此代碼時，它更喜歡只運行第一條消息。login.html <div class="loginfailure"> <h1>{{.Loginfailure}}</h1> </div>它不允許第二個消息，如果調(diào)用第二條消息，它將提供空白頁。處理程序.go注冊成功success := struct{ Signupsuccess string }{Signupsuccess: "Your account is successfully created"}loginTmpl.Execute(w, success)登錄失敗failure := struct{ Loginfailure string }{Loginfailure: "Enter the correct email or password"}loginTmpl.Execute(w, failure)登錄.html{{define "body"}} <div class="loginfailure"> <h1>{{.Loginfailure}}</h1> </div> <div class="signupsuccess"> <h1>{{.Signupsuccess}}</h1> </div> <h1>Log In</h1> <p>Login to access your account</p> <form action="/login" method="POST"> <div> <label for="email">Email</label> <input type="email" name="email" placeholder="Enter your email address" required> </div> <div> <label for="password">Password</label> <input type="password" name="password" placeholder="Enter your password" required> </div> <div> <input type="submit" value="Login"> </div> <div> <a href="/signup" class="link">Signup</a> </div> </form>{{end}}

始終檢查 返回的錯誤。Execute
在模板內(nèi)部，您不能引用在傳遞給模板的結(jié)構(gòu)中不存在的字段，即當您傳遞操作時會破壞模板，當您傳遞中斷模板時。failure{{.Signupsuccess}}success{{.Loginfailure}}
您可以使用地圖，允許引用地圖中不存在的地圖鍵
success := map[string]string{"Signupsuccess": "Your account is successfully created"}
if err := oginTmpl.Execute(w, success); err != nil {
panic(err)
}
failure := map[string]string{"Loginfailure": "Enter the correct email or password"}
if err := loginTmpl.Execute(w, failure); err != nil {
panic(err)
}
或者使用具有兩個字段的單個結(jié)構(gòu)
type TemplateData struct {
Signupsuccess string
Loginfailure string
}
success := TemplateData{Signupsuccess: "Your account is successfully created"}
if err := oginTmpl.Execute(w, success); err != nil {
panic(err)
}
failure := TemplateData{Loginfailure: "Enter the correct email or password"}
if err := loginTmpl.Execute(w, failure); err != nil {
panic(err)
}
