Here is the flask code this is correct ? I am trying for 2 days please solve  this problem. While running thus code it showing 404 and 405 method.




@app.route('/delete/<int:postID>', methods=['DELETE'])
def delete_user(postID):
if not session.get('logged_in'):
     abort(401)
sqlsession.execute('delete from values WHERE id = ?', [postID])
flash('Entry was deleted')
return redirect(url_for('pageedituser'))

Answer 1

在您的HTML中，您构建了一个GET方法。将您的方法更改为GET将解决此问题，但这不是正确的答案。答案是使用HTML表单向烧瓶服务器发出POST请求。

HTML 的

<form action="{{ url_for('delete_user', postID=values.id) }}" method="POST">
</form>

视图

@app.route('/delete/<int:post_id>', methods=['POST'])

改进答案

如果你想要使用Javascript的DELETE请求，我建议使用fetch

HTML表单元素不能直接用于POST或GET之外的任何内容，因此任何对其他方法的支持都应该通过javascript中的XMLHttpRequest来完成。

即）

HTML 的

<td><a href="#" class="btn btn-danger" onclick="deletePost(23);">Delete</a></td>

<script type="text/javascript">
    function deletePost(postId) {
      return fetch('http://localhost:5000/delete' + '/' + postId, {
        method: 'delete'
      }).then(response =>
        console.log(response)
      );
    }
</script>
