这几天和前端对接接口,前端的错误信息是:
注释:
Failed to load http://192.168.3.3:8080/Light_Push/webFrames.action?page=1&searchProject=1&page=1&searchProject=1: The value of the 'Access-Control-Allow-Origin' header in the response must not be the wildcard '*' when the request's credentials mode is 'include'. Origin 'http://localhost:8080' is therefore not allowed access. The credentials mode of requests initiated by the XMLHttpRequest is controlled by the withCredentials attribute.
前端用了vue,axios(http客户端)
后端ssm框架,spring版本是3.2.13
发现可以从后台spring跨域着手解决
解决跨域方法:
第一步:导入jar包
cors-filter-1.7.jar、java-property-utils-1.9.jar
下载地址:http://pan.baidu.com/s/1pLkLPGJ
第二步:在web.xml文件配置
<filter>
<filter-name>CORS</filter-name>
<filter-class>com.thetransactioncompany.cors.CORSFilter</filter-class>
<init-param>
<param-name>cors.allowOrigin</param-name> <!--配置授信的白名单的域名! -->
<param-value>*</param-value>
</init-param>
<init-param>
<param-name>cors.supportedMethods</param-name>
<param-value> GET, POST, HEAD, PUT, DELETE </param-value>
</init-param>
<init-param>
<param-name>cors.supportedHeaders</param-name>
<param-value> Accept, Origin, X-Requested-With, Content-Type, Last-Modified </param-value>
</init-param>
<init-param>
<param-name>cors.exposedHeaders</param-name>
<param-value>Set-Cookie</param-value>
</init-param>
<init-param>
<param-name>cors.supportsCredentials</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CORS</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
