Codeigniter CSRF错误："您请求的操作不允许。"

Question

我在codeigniter的配置文件中启用了csrf_保护选项，并使用form_open（）函数创建表单。但当我提交表单时，会出现以下错误：

不允许您请求的操作。

我已经回答了这个主题（与我的问题最相关）：问题

但是它们不起作用，问题仍然存在。

Answer 1

对我来说最简单的一个是将URI列入白名单，如CodeIgniter用户指南中所述（此处）

选择的URI可以从csrf保护中列入白名单（例如，期望外部发布内容的API终结点）。您可以通过编辑csrf_exclude_uris配置参数来添加这些URI：

$config['csrf_exclude_uris'] = array('api/person/add');

Answer 2

只要把这个写进你的表格，一切都会好起来的。

<input type="hidden" name="<?php echo $this->security->get_csrf_token_name();?>" value="<?php echo $this->security->get_csrf_hash();?>">

Answer 3

此解决方案解决的问题：

如果使用HTTP，请将配置文件中的$config['cookie_secure']设置为FALSE。
