方法1 .restlet client 把https 改为http
方法2.找到tomcat目录下的server.xml,增加以下内容

<Connector URIEncoding="UTF-8" port="8080" protocol="org.apache.coyote.http11.Http11NioProtocol"
    useBodyEncodingForURI="false"
    enableLookups="false"
               connectionTimeout="20000"
               redirectPort="8443" maxHttpHeaderSize="你想要的大小"/>
