如何在同一文件中运行两个匿名结构？

Question

在此代码中，我有两条消息。

1-第一个是注册您的帐户已创建。现在登录到一个帐户，然后

2-第二个是登录失败，即如果电子邮件或密码不匹配，则给出错误消息。

我已经在文件中调用了这两条消息，但是当我运行此代码时，它更喜欢只运行第一条消息。login.html

 <div class="loginfailure">

        <h1>{{.Loginfailure}}</h1>

    </div>

它不允许第二个消息，如果调用第二条消息，它将提供空白页。

处理程序.go

注册成功

success := struct{ Signupsuccess string }{Signupsuccess: "Your account is successfully created"}

loginTmpl.Execute(w, success)

登录失败

failure := struct{ Loginfailure string }{Loginfailure: "Enter the correct email or password"}

loginTmpl.Execute(w, failure)

登录.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}}

始终检查 返回的错误。Execute在模板内部，您不能引用在传递给模板的结构中不存在的字段，即当您传递操作时会破坏模板，当您传递中断模板时。failure{{.Signupsuccess}}success{{.Loginfailure}}您可以使用地图，允许引用地图中不存在的地图键success := map[string]string{"Signupsuccess": "Your account is successfully created"}if err := oginTmpl.Execute(w, success); err != nil {&nbsp; &nbsp; panic(err)}failure := map[string]string{"Loginfailure": "Enter the correct email or password"}if err := loginTmpl.Execute(w, failure); err != nil {&nbsp; &nbsp; panic(err)}或者使用具有两个字段的单个结构type TemplateData struct {&nbsp; &nbsp; Signupsuccess string&nbsp; &nbsp; Loginfailure string}success := TemplateData{Signupsuccess: "Your account is successfully created"}if err := oginTmpl.Execute(w, success); err != nil {&nbsp; &nbsp; panic(err)}failure := TemplateData{Loginfailure: "Enter the correct email or password"}if err := loginTmpl.Execute(w, failure); err != nil {&nbsp; &nbsp; panic(err)}
