Go martini handling of HTML form data

问题

我遇到了从HTML表单获取数据的问题。
模板显示在localhost:3000,我提交后被带到localhost:3000/results,显示"404页面未找到"的结果。URL中不包含任何表单字段。

以下是要翻译的代码部分:

package main

import (
	"html/template"
	"net/http"
	"github.com/go-martini/martini"
)

func main() {
	m := martini.Classic()
	m.Get("/", func(res http.ResponseWriter, req *http.Request) { // res and req are injected by Martini
		t, _ := template.ParseFiles("form.gtpl")
		t.Execute(res, nil)
	})

	m.Get("/results", func(r *http.Request) string {
		text := r.FormValue("text")
		return text
	})
	m.Run()
}

模板内容如下:form.gtpl

<html>
<head>
<title>Title Here</title>
</head>
<body bgcolor="#E6E6FA">
<h1>Header Here</h1>
<form action="/results" method="POST">
	Date: <input type="text" name="dated" size="10" value="01/12/2015">        
	Triggers: <input type="text" name="triggers" size="100" value="Trigger1|Trigger2"><br><br>
    <textarea name ="text" rows="20" cols="150">random text here
</textarea>
    <input autofocus type="submit" value="Submit">
</form>
</body>
</html>
英文:

I am having trouble getting data from the HTML form.
The template shows at localhost:3000, I submit and am taken to localhost:3000/results with a "404 page not found" results. The URL does not include any of the forms fields.

package main

import (
	&quot;html/template&quot;
	&quot;net/http&quot;
	&quot;github.com/go-martini/martini&quot;
)

func main() {
	m := martini.Classic()
	m.Get(&quot;/&quot;, func(res http.ResponseWriter, req *http.Request) { // res and req are injected by Martini
		t, _ := template.ParseFiles(&quot;form.gtpl&quot;)
		t.Execute(res, nil)
	})

	m.Get(&quot;/results&quot;, func(r *http.Request) string {
		text := r.FormValue(&quot;text&quot;)
		return text
	})
	m.Run()
}

and the template is: form.gtpl

&lt;html&gt;
&lt;head&gt;
&lt;title&gt;Title Here&lt;/title&gt;
&lt;/head&gt;
&lt;body bgcolor=&quot;#E6E6FA&quot;&gt;
&lt;h1&gt;Header Here&lt;/h1&gt;
&lt;form action=&quot;/results&quot; method=&quot;POST&quot;&gt;
	Date: &lt;input type=&quot;text&quot; name=&quot;dated&quot; size=&quot;10&quot; value=&quot;01/12/2015&quot;&gt;        
	Triggers: &lt;input type=&quot;text&quot; name=&quot;triggers&quot; size=&quot;100&quot; value=&quot;Trigger1|Trigger2&quot;&gt;&lt;br&gt;&lt;br&gt;
    &lt;textarea name =&quot;text&quot; rows=&quot;20&quot; cols=&quot;150&quot;&gt;random text here
&lt;/textarea&gt;
    &lt;input autofocus type=&quot;submit&quot; value=&quot;Submit&quot;&gt;
&lt;/form&gt;
&lt;/body&gt;
&lt;/html&gt;

答案1

得分: 4

在你的表单中,你指定了method="POST",但是在服务器代码中,你使用了m.Get("/results",...)。这一行应该改为m.Post("/results",...)。Martini试图路由请求,但是没有定义POST /results,只有GET /results

英文:

Notice in your form you've specified method=&quot;POST&quot;, but in the server code you have m.Get(&quot;/results&quot;,...). That line should be m.Post(&quot;/results&quot;,...). Martini is trying to route the request but there is no definition for POST /results only GET /results

答案2

得分: 0

将 m.GET 更改为 m.POST,然后问题解决了。

英文:

changed m.GET to m.POST, and voilà fixed.
