问题内容

我尝试将 golang 服务器链接到我的 html 联系表单，这是我的文件夹结构下图是文件夹结构..以下是 server.go 文件：

package main

import (
    "html/template"
    "net/http"
)

type contactdetails struct {
    fname string
    email   string
    telephone string
    subject string
    message string
}

func main() {
    tmpl := template.must(template.parsefiles("contact.html"))

    http.handlefunc("/", func(w http.responsewriter, r *http.request) {
        if r.method != http.methodpost {
            tmpl.execute(w, nil)
            return
        }

        details := contactdetails{
            fname:  r.formvalue("fname"),
            email:   r.formvalue("email"),
            telephone: r.formvalue("telephone"),
            subject: r.formvalue("subject"),
            message: r.formvalue("message"),
        }

        // do something with details
        _ = details

        tmpl.execute(w, struct{ success bool }{true})
    })

    http.listenandserve(":8080", nil)
}

以下是 contact.html 代码：

该程序似乎无法运行。我需要帮助才能完成这项工作。如果有办法可以链接文件或重组文件夹。

解决方案

在 html 中，您有：

&lt;input type=&quot;name&quot; id=&quot;form-name&quot; class=&quot;form-control&quot;&gt;

在 go 代码中，您有：

fname:  r.formvalue("fname"),

传递给r.formvalue的参数需要与输入标签中的“名称”匹配：

&lt;input type=&quot;name&quot; id=&quot;form-name&quot; class=&quot;form-control&quot; name=&quot;fName&quot;&gt;

您正在使用不存在的表单值填充结构。完整的示例可以在这里找到：https://astaxie.gitbooks.io/build-web-application-with-golang/content/en/04.1.html
