【问题标题】：Springboot authentication issueSpring Boot 身份验证问题
【发布时间】：2019-02-13 22:46:46
【问题描述】：

我有一个配置了 spring 安全性的 spring boot 应用程序。我已将登录请求重定向到http://localhost:8000，我在 python 服务器上运行我的前端。现在，当我尝试将登录信息发布到我的 springboot 应用程序时，它不起作用。即使我从邮递员那里尝试，它也会显示405 错误。我怎样才能得到这个工作。如果我将它作为 html 放在同一个项目中而不是从 python 服务器或邮递员中，它可以从 /login 中工作。有什么区别。

"message": "不支持请求方法'POST'", “路径”：“/登录”

【解决方案1】：

您忘记包含 csrf 值。这是一种防止跨站点攻击的安全预防机制。您有两种解决方法：

1.禁用CSRF：

由于默认情况下启用了 csrf，因此在启用 CSRF 的情况下不允许使用 POST 和 PUT Http 方法。要禁用它，您应该将其添加到您的安全配置中

.csrf().disable()

例如你可以有这样的东西：

http.
.csrf().disable().
authorizeRequests()
        .antMatchers("/admin/**").access("hasRole('ROLE_ADMIN')")
        .and()
          .formLogin().loginPage("/login").failureUrl("/login?error")
          .usernameParameter("username").passwordParameter("password")
        .and()
          .logout().logoutSuccessUrl("/login?logout")
        .and()
          .exceptionHandling().accessDeniedPage("/403");

2.发送csrf令牌值：

如果您使用带有登录表单的登录页面，我们需要始终将登录表单中的 CSRF 令牌作为隐藏参数手动包含在代码中：

<input
  type="hidden"
  th:name="${_csrf.parameterName}"
  th:value="${_csrf.token}" />

如果你想通过ajax登录你还应该包括这两个参数：

首先保存一些变量中的值：

<script type="text/javascript">
    var csrfParameter = '${_csrf.parameterName}';
    var csrfToken = '${_csrf.token}';
</script>

然后将它们包含在

中

var jsonParams = {};
jsonParams['parentId'] = 1;
jsonParams[csrfParameter] = csrfToken;
// include other values pass ,user, etc.

$.ajax({
    type: 'POST',
    cache: false,
    url: /login,
    data: jsonParams,
    dataType = 'json',
    contentType = 'application/json',

    ...
});
