英文:
why do i keep getting a "Method not allowed" on my html template whenever i try using http.MethodDelete?
问题
我正在使用http.MethodDelete来尝试从我的HTML模板中删除引用。每次我点击删除按钮时都会收到错误消息。
我尝试在我的HTML模板中使用以下代码："<a class="delete-button" href="/quote/delete?quote_id={{ .QuoteID}}">Delete</a> "，但仍然出现错误。
英文:
I am using http.MethodDelete to try and delete quotes from my html template. Everytime i press the delete button i get the error message.
I tried using this inside my html template, "<a class="delete-button" href="/quote/delete?quote_id={{ .QuoteID}}">Delete</a> " but it still gives me the error.

我认为你的意思是这样的：
router.HandlerFunc(http.MethodDelete, "/quote/delete", app.quoteDelete)
<a class="delete-button" href="/quote/delete?quote_id={{ .QuoteID }}">Delete</a>
默认情况下，浏览器通过发送GET请求来跟踪链接。它不会像你期望的那样发送DELETE请求。
你可以使用JavaScript代码发送DELETE请求。
看起来你的项目中没有编写任何JavaScript代码，所以一个快速的解决方法是修改服务器代码来处理POST请求，并使用表单发送POST请求到删除资源的端点：
router.HandlerFunc(http.MethodPost, "/quote/delete", app.quoteDelete)
<form action="/quote/delete?quote_id={{ .QuoteID }}" method="post">
<button type="submit">Delete</button>
</form>
请注意，表单不能用于发送DELETE请求。表单元素的允许方法在MDN的表单元素文档中列出：
method用于提交表单的HTTP方法。允许的方法/值仅限于（不区分大小写）：
post：使用POST方法，将表单数据作为请求体发送。get（默认）：使用GET方法，将表单数据附加到带有?分隔符的操作URL中。当表单没有副作用时使用此方法。dialog：当表单位于<dialog>内时，关闭对话框并在提交时触发提交事件，而不提交数据或清除表单。
关于HTTP请求方法的定义，请参阅HTTP请求方法。

I think you mean this:
router.HandlerFunc(http.MethodDelete, "/quote/delete", app.quoteDelete)
<a class="delete-button" href="/quote/delete?quote_id={{ .QuoteID}}">Delete</a>
By default, a browser follows a link by sending a GET request. It does not send a DELETE request as you expected.
You can send a DELETE request using JavaScript code.
It seems that you haven't written any JavaScript code in your project, so a quick fix is to modify the server code to handle the POST request and use a form to send a POST request to the delete resource endpoint:
router.HandlerFunc(http.MethodPost, "/quote/delete", app.quoteDelete)
<form action="/quote/delete?quote_id={{ .QuoteID }}" method="post">
<button type="submit">Delete</button>
</form>
Please note that a form can not be used to send a DELETE request. The allowed methods of a from element are listed on the doc for the Form element from MDN:
> method
>
> The HTTP method to submit the form with. The only allowed methods/values are (case insensitive):
>
> - post: The POST method; form data sent as the request body.
> - get (default): The GET; form data appended to the action URL with a ? separator. Use this method when the form has no side effects.
> - dialog: When the form is inside a <dialog>, closes the dialog and causes a submit event to be fired on submission, without submitting data or clearing the form.
