啓用了不安全的http請求方法 OPTIONS

tomcat配置：

在tomcat的web.xml中添加如下的代碼後重啓tomcat，注意添加後只對tomcat下的目錄有效。參照所需禁用的http方法添加。

<security-constraint>  
   <web-resource-collection>  
      <url-pattern>/*</url-pattern>  
      <http-method>PUT</http-method>  
<http-method>DELETE</http-method>  
<http-method>HEAD</http-method>  
<http-method>OPTIONS</http-method>  
<http-method>TRACE</http-method>  
   </web-resource-collection>  
   <auth-constraint>  
   </auth-constraint>  
 </security-constraint>  
 <login-config>  
   <auth-method>BASIC</auth-method>  
 </login-config>

如果是其他應用程序，配置如下：

<?xml version="1.0" encoding="UTF-8"?>  
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"  
    version="2.4">
