StartTimestamp;EndTimestamp，即为 KeyTime。例如：1557902800;1557910000。eb2519b498b02ac213cb1f3d1a3d27a3b3c9bc5f。/?acl，则认为是/?acl=。?以后的部分，例如请求路径为/?versions&prefix=example-folder%2F&delimiter=%2F&max-keys=10，则请求参数为versions&prefix=example-folder%2F&delimiter=%2F&max-keys=10。key1=value1&key2=value2&key3=value3，即为 HttpParameters。key1;key2;key3，即为 UrlParamList。/?prefix=example-folder%2F&delimiter=%2F&max-keys=10
UrlParamList：delimiter;max-keys;prefix
HttpParameters：delimiter=%2F&max-keys=10&prefix=example-folder%2F/exampleobject?acl
