+    cors命令通过设置method选项值为put、get,可以设置、查询bucket的TLS版本设置
+
+用法:
+    该命令有两种用法:
+
+    1) ossutil https-config --method put oss://bucket local_xml_file
+        这个命令从配置文件local_xml_file中读取TLS版本设置，然后设置bucket的TLS版本设置
+        配置文件是一个xml格式的文件，举例如下
+
+        <?xml version="1.0" encoding="UTF-8"?>
+        <HttpsConfiguration>  
+		  <TLS>
+			<Enable>true</Enable>   
+			<TLSVersion>TLSv1.2</TLSVersion>
+			<TLSVersion>TLSv1.3</TLSVersion>
+		  </TLS>
+		</HttpsConfiguration>
+
+    2) ossutil https-config --method get oss://bucket [local_xml_file]
+        这个命令查询bucket的TLS版本设置
+        如果输入参数local_xml_file，TLS版本设置将输出到该文件，否则输出到屏幕上
+`,
+	sampleText: ` 
+    1) 设置bucket的TLS版本设置
+       ossutil https-config --method put oss://bucket local_xml_file
+
+    2) 查询bucket的TLS版本设置，结果输出到标准输出
+       ossutil https-config --method get oss://bucket
+
+    3) 查询bucket的TLS版本设置，结果输出到本地文件

+    cors command can set、get the https configuration of the oss bucket by
+    set method option value to put, get
+
+Usage:
+    There are two usages for this command:
+
+    1) ossutil https-config --method put oss://bucket local_xml_file
+
+        The command sets the https configuration of bucket from local file local_xml_file
+    the local_xml_file is xml format
+        The following is an example of the contents of local_xml_file
+
+        <?xml version="1.0" encoding="UTF-8"?>
+        <HttpsConfiguration>  
+		  <TLS>
+			<Enable>true</Enable>   
+			<TLSVersion>TLSv1.2</TLSVersion>
+			<TLSVersion>TLSv1.3</TLSVersion>
+		  </TLS>
+		</HttpsConfiguration>
+
+    2) ossutil https-config --method get oss://bucket [local_xml_file]
+        The command gets the https configuration of bucket
+        if you input parameter local_xml_file,the configuration will be output to local_xml_file
+        if you don't input parameter local_xml_file,the configuration will be output to stdout
+`,
+	sampleText: ` 
+    1) put https configuration
+       ossutil https-config --method put oss://bucket  local_xml_file
+
+    2) get https configuration to stdout
+       ossutil https-config --method get oss://bucket
+
+    3) get https configuration to local file
+       ossutil https-config --method get oss://bucket  local_xml_file
