+/**
+ * A tool class for uniformly formatting the keys of Entry's ExtendedMap <br>@date 2024/4/9 10:44<br>
+ * Process "Seaweed-" prefix, consistent with http upload file situation
+ * <br>
+ *
+ * <b>Premise:</b>
+ * <br>
+ * curl -H "Seaweed-name1: value1" -F file=to/path "http://localhost:8888/"
+ * <br>
+ * When uploading files using Http, you must add the "Seaweed-" prefix to the key of Extended. As shown above,
+ * the final storage result is Seaweed-name1, The name of key that actual users understand should be name1
+ * <br>
+ * The key of Extended is not forced to add the "Seaweed-" prefix when uploading files using FilerClient.
+ * This causes inconsistency in the key of Extended format of the two file upload methods.
+ * <br>
+ * <b>solution:</b>
+ * When storing Entry, add the "Seaweed-" prefix to the Extended key,
+ * and remove the "Seaweed-" prefix when reading Entry information.
+ * Users will not be aware of the "Seaweed-" prefix when using it,
+ * and the format of the Extended key in the two upload methods will be unified.
